ABOUT THIS
ISSUE
In the 1960s romantic sitcom, I Dream of
Jeannie, Barbara Eden plays a genie Jeannie. Jeannie is a couple of thousand
years old, beautiful, and sometimes lives in a bottle. Her so-called master
is an astronaut. Jeannie, who today might be called a nanogenie, is the same in
miniature as she is in her larger form. Unfortunately, for our health of
ourselves and the environment, such may not be true for nanomaterials. Quantum
rather than conventional physics applies when the scale is at the atom and
molecule level. In this issue we look at the challenge of nanomaterials and
share some ideas of what needs to be done to ensure their adequate
safety.
As always we have some general news and views.
Asahi Glass Foundation recently gave its Blue Planet award for
environmental work; Environment Canada has a project researching links between
science and policy development, and we pass on a couple of reports on climate
issues, with much more to come later this Fall. A correspondent asked us what we
think about the work of Bjorn Lomborg, the Skeptical Environmentalist, so
instead of telling you what we think we share the thoughts of a number of people
and organizations with much more expertise than GL. You can even read about the
findings of the Danish Committee on Scientific Dishonesty, the kind of
organization that is sorely needed here in North America. We end this issue with
a commentary on the Nobel Peace Prize recently awarded to President Obama.
Somehow we think it unlikely that Prime Minister Harper will receive a similar
honour, at least not this year!
Our next issue will follow up on the Ontario
Environment Commissioner’s recent exposure of the democratic unfairness of SLAPP
suits against those who oppose almost anything. How far we have come from the
1980's and 1990's when governments and at least some industry leaders recognized
the value of citizen participation in the making of public policy. While waiting
for the next issue we encourage you to submit your comments on this one, or on
anything else relevant to the field of environment and Sustainable
Development.

CAN SUNCOR
BECOME AN ENERGY LEADER?
It was fascinating to hear Rick George, CEO of
Suncor, Canada’s largest energy company, call at a recent luncheon of the
Economic Club of Canada for a national energy strategy for Canada. Sure he
called it a sustainable national energy strategy and certainly he remarked, in
an aside, that he was not calling for a return to the National Energy Program,
that Trudeau-era initiative that Albertans still love to hate, but there was no
doubt about it - here was the CEO of Canada’s largest oil company calling on a
federal government with a very significant Alberta base to adopt a plan for
Canada’s energy future. Even the most brash of Canada’s environment and energy
NGOs have not been so brave for a long time.
Of course George is right - if we do not know
where we are going we have no hope of knowing whether we have arrived, or even
whether we are making progress. Many of his suggested elements also make a lot
of sense in the context of sustainable development:
- We need to assess our likely energy
requirements 10, 20 and even 50 years down the road, based on what kind of
society we want to build.
- We should determine the mix of proven and
potential energy sources that can best meet those domestic requirements, and
identify the additional resources we want to develop for export to sustain
economic growth, provide jobs and generate government revenues that fund
essential public services.
- We need to understand the future is about
increasing energy choice, not restricting it. The global population is set to
grow from 6 to 9 billion people and they will need energy to develop their
societies. We should work to ensure alternative sources such as solar, wind,
geothermal and biofuels are part of the mix and use conventional sources to
help drive research and development of alternatives and new technologies.
- We must find ways to build the required
infrastructure to deliver energy where it is needed and when it is needed. The
current system of pipelines and transmission lines are testament to what
happens when you don’t have a clear national energy strategy.
- Targets and goals for reducing greenhouse gas
emissions must be an integral part of this national plan. In fact, a sound
energy strategy will in large part become our climate change strategy.
- A sustainable energy strategy must go well
beyond the issue of basic energy production. After all, up to 80% of
greenhouse gas emissions from a barrel of oil are generated through the
tailpipe.
- Improved vehicle energy efficiency, better
standards for building construction, more mass transit and a renewed
conservation ethic all need to be part of any national plan.
But despite the wisdom of George’s proposal
for a National Energy Strategy, Canada needs more. First, Canadians concerned
about the environment need to be convinced that the Alberta oil sands are
something other than an environmental disaster in the making. George told the
Economic Club that claims that the carbon footprint of oil sands crude is three
to five times higher than other crude oil products are simply not true. He said
that independent studies show that oil sands crude is only marginally more
carbon-intensive than many other crude sources and actually less
carbon-intensive than many conventional sources. GL has not yet found
peer-reviewed reports to support the claim, so those making it need to prove it
with hard data, independently verified and made readily available to the public.
It needs to be true not just for Suncor’s operations but for those of all other
oil sands companies. The oil industry also needs to demonstrate how the land
area affected by mining of oil sand is going to be restored to habitat
equivalent to that which existed before mining. It needs to demonstrate that not
one drop of contaminated water leaves the mining and processing sites. It needs
to mitigate the adverse effects on air quality.
Suncor, as the largest Canadian player, has
the opportunity to pull the petroleum industry out of the dark ages. Even today,
the Canadian Association of Petroleum Producers repeatedly presses the point
that “about 75 per cent of GHG emissions occur during fuel consumption and are
not impacted by the source of the crude oil”. Hardly a mantra for industry
leadership, given that the petroleum industry itself is arguably better placed
than any other industry to encourage fuel conservation measures, just as many
electricity utilities are doing.
The downstream side of the oil industry, to
which Suncor also belongs, is represented by the Canadian Petroleum Products
Institute. CPPI distributes via its websites the claim that “Today’s gas, in
today’s cars, produces no smog-causing emissions”. In an associated brochure it
also claims that “since the Kyoto Protocol was signed in 1997, . . . our
industry’s greenhouse gas emissions, particularly carbon dioxide (CO2), have not
increased.” Both statements are for the gullible and can only bring an
industry’s credibility into disrepute.
Finally, George needs to recognize that this
federal government is totally disinterested in a National Energy Strategy.
Suncor, as the second largest Canadian company of any kind, is more than capable
of taking the lead in developing the strategy and ramming it down the
government’s throat. George should give serious consideration to appointing a
National Energy Strategy Round Table, inviting others in the industry to
participate along with leaders from environmental organizations, energy experts,
labour, first nations, energy consuming goods manufacturers, and communities.
Governments should also be invited to participate. The exercise should be
adequately funded, not just from Suncor but from other industrial and private
sector sources. The group should be given no more than 24 months to develop and
publish a National Energy Strategy for Canada.
Putting money and resources where your mouth
is demonstrates a real commitment to Sustainability. As the second largest
Canadian company, Suncor has the potential to show true business leadership
towards a sustainable energy future for Canada. Gallon Environment Letter urges
Rick George to rise to the cause.

NANOMIRACLE,
OR NOT?
Although the term is now commonly seen in the
media, nanotechnology isn't a sector or even a specific technology. It seems
that one can put the word nano in front of almost anything - there are
nanotextiles, nanodiamonds, nanotubes, nanofilms, nanostructures, nanobots
(robots) and endless actual and potential applications including non-invasive
tests and cures for cancer. These have nothing in common except that they or
their components are ultrasmall. Recently there have been news stories that
nanotechnology will enable immortality as nanobots repair and replace cells.
Before we get there though, someone needs to examine the environmental and
health impacts. We begin that process through a review of some recent
publications.
While in the early years, the emphasis was all
on the amazing potential of nanotechnology, it seems that the hazards are
beginning to draw more attention. Dr.Shuji Abe, Deputy Director, Nanotechnology
Research Institute National Institute of Advanced Industrial Science and
Technology (AIST), Japan, suggests that industry is more cautious when entering
into decisions about the production of nanomaterials due to concerns about the
environmental and health effects. He says that there is no easy way around EHS
issues in the development and use of nanotechnologies.

IEHN:
DISCLOSURE OF NANO WEAK
In June, the US-based Investor Environmental
Health Network, which includes ngos as well as investment management firms,
compared the lack of disclosure about nanotechnology to what the group calls the
"asbestos litigation disaster for investors." It calls on the securities
commission to close eight major loopholes to improve disclosure.

NANOTECH MAY
HAVE NO ROLE IN ORGANIC AGRICULTURE
Tanya Brouwers, consultant to The Organic
Agriculture Centre of Canada, wrote about the need to assess whether
nanotechnology materials are suitable for organic certification. OACC is a
research and education centre headed by Ralph Martin Ph.D, P. Ag Professor at
the Nova Scotia Agricultural College. Brouwers describes some of the farm
application such as miniature sensors providing detailed crop needs for
fertilizers, pesticides and herbicides or sensors embedded in dairy cows which
provide treatment even before the farmer knows of any problem. Estimated to be
worth $9 billion a year, nanotechnology is already found in cosmetics, food
packaging and of course, agriculture and in five to ten years, the scenarios she
mentions are expected to become actualities.
Companies such as Bayer and BASF have used
nanoscale ingredients to give more killing power to pesticides claiming that
less input means less pollution. Nanotech is being used in Thailand to change
the DNA of rice so it will grow all year, have an attractive colour and shorter
stems. Nanotechnology is touted as ending starvation; critics say this was also
the promise of biotechnology but it has had unintended consequences and famines
are still common. Brouwers writes, " Most disturbing is the fact that
nanotechnology has, like genetic engineering, been developed and pushed into the
market place without any form of public debate or political legislation
regarding its potential health, environmental and socioeconomic risks. The
little amount of publically documented research that does exist regarding human
health and nanotechnology demonstrates that nano-particles can be taken up from
the air, food, drink and through the skin, and can, given their unnaturally
small size, pass through cell membranes into tissues like the brain or a
developing fetus."
Some organic certifiers such as the UK Soil
Association and the OCIA are banning use of engineered nano-materials. The
Canadian Organic standard which came into law in June 2009 hasn't addressed
nanotechnology. Brouwers suggests that "Given the recent backlash to genetic
engineering, a similar response is expected for products of nanotechnology. It
is quite possible that the organic industry will attract a whole new clientele:
those that prefer their food “nano-free”.

AMEC BOOK:
NANOTECHNOLOGY AND THE ENVIRONMENT
Christopher Mackay, an environmental chemist
and toxicologist whom we met at one of the science conferences we recently
attended told us that AMEC had given a group of in-house scientists $50,000 and
asked them to write a book on nanotechnology and the environment. GL found the
book a good insight into the science as well as the initiatives underway to link
the science to policy such as environmental regulations, mostly American but
also some others.
The book describes the lifecycle of nanoscale
materials from manufacture to the possible points of exposure, with some
estimate of the consequences of exposure. It outlines the state of the science,
a rapidly moving field, and suggests priority areas requiring
research.
Nanotechnology is applied science with matter
at 1 to 100 nanometers (nm). A nm is one-billionth of a metre. (GL notes the
diameter of a human hair is about 60,000 nm) The extremely small size means nano
materials of the same chemistry as regular-sized materials may have different
properties e.g. increased physical strength or different chemical reactivity.
These properties are seen by proponents to have applications for almost
everything - textiles, paints and coatings, pharmaceuticals, energy,
electronics.
Public
awareness is low
A number of surveys in Great Britain, Japan,
and the US from 2003 to 2007 indicate general lack of much public knowledge. For
example, in the most recent 2007 one of 1014 adults in the US, "Approx. 70%
had heard just a little or nothing at all about nanotechnology." Those who had
heard about it tended to think that the benefits outweighed the
risks.
Benefits and
risks
History has many examples of revolutionary new
inventions which have left a legacy of hazardous waste instead of progress e.g.
gas lights fueled by pyrolysis of coal and oil left cyanide compounds polluting
groundwater and soil. MTBE added to gasoline to replace lead polluted
waterways.
The potential benefits of nanotechnology
include:
-
Energy: Lightweight composites in
automobiles, thinner coatings can reduce weight of automobiles and aeroplanes
reducing fuel consumption. Nano additives to fuel can increase
efficiency.
-
Renewable Energy: Nano could help to produce
cheaper solar cells, to produce batteries for electric cars or provide storage
through hydrogen fuel cells.
-
Efficient use of resources: Nano could
replace more expensive rarer metals and platinum. Nano zeolite catalysts are
used now for cracking oil. They may also be substitutes for more hazardous
materials such as nano solders instead of lead.
-
Environmental Protection: Nanomaterials are
used in wastewater treatment and soil remediation, may have applications in
air pollution and may be used to detect chemical contamination.
-
Agricultural applications: Nanodevices could
deliver "smart" treatment delivering fertilizer and pesticides as needed
reducing the overall application and runoff.. Nanocontainers could eliminate
the need for solvents and concentrates often used in agricultural chemical
systems.
-
Medical: Nano can build artificial bone and
may be used for other prosthetic devices. Drug delivery and medical imagery
are also proposed.
The potential risks and perceived risks
include:
- incomplete knowledge. Government agencies
have not assessed environmental exposure to nanomaterials.
- in vitro tests have shown effects of
nanomaterials on cell lines
- some bioassays have shown toxic
effects
- the most important pathway may be inhalation
of nanoparticles which may cause inflammation or immune response.
- other materials used in the manufacture,
distribution of nanomaterials may be harmful e.g. some nanomaterials are
shipped stored in caustic chemicals. C60 fullerenes are manufactured using
toxic benzene
- disposal of commercial products containing
nanomaterials at the end-of-life may cause exposure as yet
unknown.
The Nanotechnology Consumer Products Inventory
by the Woodrow Wilson Institute listed 500 consumer products by the end of 2007*
Katherine Sellers, an engineer, writes in the
introduction, "Some of these product descriptions illustrate how manufacturers
can guard the details of proprietary technology by providing little information
about the nanomaterials in their products."
Properties
Common nanomaterials discussed in this book:
particles of titanium dioxide, iron, silver, carbon (known as carbon black),
carbon nanotubes (a tube which may be a single layer or multiple layers of
carbon atoms), and buckeyballs (hollow spheres called fullerenes and usually
made of carbon atoms e.g. C60 fullerene is 60 carbon atoms.)
Naturally occurring nanoscale materials: ash
from volcanoes, viruses, human-caused activities such as burning of diesel and
welding to release very small particulates. The term nanotechnology usually
applies only to the engineered materials.
Nanomaterials come in all kinds of shapes and
structure: particles, crystals, tubes, wires, rods, branches called dendrimers,
composites, and sphere. The National Institute for Occupational Safety and
Health has 11 categories and other agencies classify them in different ways. The
shape and structure may affect whether the nanoparticle can enter the human or
other living body or how it reacts physically in certain settings.
Free nanoscale materials are those in solution
or suspension and are more likely to result in exposure during manufacture, use
and after the end-of-life of the product. Examples are diesel fuel with cerium
oxide for emissions reduction, sunscreens using titanium dioxides, face creams
with fullerenes, drugs containing dendrimers, and foods such as vegetable oils
containing nanodrops of supplements such as vitamins.
Fixed nanoparticles are less likely to be
released into the environment. Examples include nanotubes used to strengthen
tennis racket, carbon black reinforcing rubber products, and nanoscale
transistors in electronics.
Small particles tend to remain suspended and
may become more dispersed in air and water. The size may mean they can enter the
human or other living body through skin or into organs.
GL has written previously about the fires that
have been caused by dust from grain or other sources. Nanoparticles suspended in
the air can explode if there is an ignition source.
Nanoparticles can agglomerate, changing the
size and the behaviour compared to the original nanoparticles or structures.
Under other circumstances, nanoparticles may disperse from the
assembly.
A positive or negative charge on the surface
of the nanomaterials affects reactivity and stability.
Nanoscale materials have different properties
from larger-scale materials for two main reason:
- they are so small that the relative surface
area is large compared to each unit of mass, increasing the reactivity
significantly.
- quantum effects apply to very small objects.
While regular physics affects nanoparticles, they are also influenced by
quantum effects, changing optical, magnetic and electrical properties and
potentially causing nanoparticles to agglomerate or adsorb to each other.
While a pencil with a graphite pencil lead doesn't conduct electricity, an
atom thick carbon nanotubes can act as a semi-conductor even though it is not
metal. Centuries ago, glass blowers used to use very fine particles of gold to
add colour to stained glass, producing red, purple, green or
orange.
It is difficult for scientists to use what
they already know about regular materials to evaluate nanomaterials. The book
includes an almost 5 page long table of critical properties of nanomaterials and
which of three reporting and framework programs are collecting data on each
specific property.
Ecological
hazards
The chapter on the potential ecological
hazards of nanomaterials discusses the question :"If a nanomaterials were to be
released into the general environment, would it pose a significant risk to
ecological organisms such as fish or wildlife?" Issues include:
- the tendency of nanomaterials to aggregate
and sorb (to be taken up) onto environmental media limits their
bioaccessibility. Even though they are small, they might bioconcentrate to a
degree but because they are often solid they would not bioaccumulate or
biomagnify in the food chain.
- Depending on the manufacturer and the
process, even the same kind of nanomaterials could be quite different.
- Bulk nanomaterials may contain impurities or
byproducts that could affect the toxicity. For example, carbon nanotubes have
been found to contain iron, cobalt and molybdenum (which is used as a
catalyst) as well as smaller amounts of chromium, copper and lead.
- Some nanomaterials are toxic materials in
their own right such as heavy metals and can enter cells such as the human
lung.
- there are many questions about whether the
design of experiments to test nanomaterials for toxicity are scientifically
valid. Many toxicity tests in conventional testing requiring dissolving the
material in water but many nanoparticles are insoluble in water.
- they are not expected to act like asbestos
because nanoparticles are so small they are more like a gas to be carried very
high into the stratosphere or washed down into soil and water by a rainstorm.
They may also enter the environment through wastewater discharges, such as
industrial waste streams, effluent from wet scrubbers used for pollution
control
Exposure possibilities are through ingestion,
dermal contact, or inhalation:
- In soil, nanoparticles would tend to bind
with micropores in the soil and become unavailable or could get washed through
the soil horizon. Except for invertebrates such as earthworms, most other
animals don't eat much soil e.g. voles, gophers eat less than 1% of their
diet.
- Least likely is dermal as most animals have
protection e.g. fish scales overlap, mammals have fur, birds feathers, many
insects thick dermal layer. Amphibians have semi-permeable skin, though.
- Most animals are likely to be affected mostly
by the lung. e.g. aquatic animals such as fish through gills.
Fullerenes have strong antibacterial action so
disposal can create environmental impacts.
Insoluble nanoparticles would tend to bind
with other insoluble materials and settle into the bed sediments. They could
still pose a risk to sediment species.
The traditional toxicology measures may not
apply for example, How does the researcher define a dose? Although nanoparticles
can be counted, there is no standardization as to how they are made. As each
manufacturer has a different kind, a test done for one isn't applicable to
another, like comparing apples with oranges To be scientifically valid, one lab
has to be able to reproduce the results of another. So far, the relative hazard
in laboratory settings of bioassays of aquatic species indicates a low to
moderate range of relative hazard. Colloidal silver may represent more hazard
because it is both soluble in water and silver is toxic to aquatic
organisms.
It might be possible to manage the risks, "But
the oft-quoted phrase "those that ignore history are doomed to repeat it" may
hold true if there is little to no communication between scientists
(particularly between toxicologists and industrial hygienist with research
scientists who are inventing these materials at a rapid rate), regulators and
the public. It would be prudent to treat each new nanomaterials in the same way
society treats each new chemical compound, and the only way to do that is
through the use of a carefully selected battery of tests and
bioassays."
Health risk
assessment
While the lung is the prime area of concern
with respect to nanomaterials exposure, research indicates that nanomaterials
can get in the blood stream through the skin and circulate into organs and
tissues, accumulating and causing organ damage. Cardiovascular disease may
result. The conclusion is that "Nanomaterials are less likely to induce systemic
effects and more likely to act as contact toxicants. Furthermore, the size of
the material's particles makes it likely that the physiological response will be
of an immune or inflammatory nature." Adverse effects are unlikely to follow a
dose-response and could be highly variable in the population depending on the
sensitivity of the person.
GL only touches on some of the topics in the
book which is a good technical basis to understand this so-called emerging
technology which is already in use. A large number of scientific studies are
summarized in chart form. There are also chapters on manufacturing processes,
methods for measuring and monitoring nanoparticles in the environment (many
challenges and not readily available), environmental fate and transport,
treatment of nanoparticles in water, and use of nanoparticles in pollution
control, and a final chapter on balancing risks and rewards. Although it is
probable that some will find this a little too technical, the authors do a good
job of explaining what is done to test, say for toxicity of a conventionally
sized chemical, and then what is the same or different for an ultrafine
particle. Readers making their way through this might still not be able to
understand research articles elsewhere entitled "Staple single-unit-cell
nanosheets of zeolite MFI as active and long-lived catalysts" but will be well
on the way to understanding what might be needed as a general framework of
environmental health and safety and why businesses ought to be alert to a
growing demand for such a framework by the public.

2008 REPORT:
SMALL IS DIFFERENT AND NEEDS REGULATION
In 2007 the Expert Panel on Nanotechnology was
set up by the Council of Canadian Academies at the request of the federal
Minister of Health. Chaired by Pekka Sinervo, then Dean, Faculty of Arts and
Science at the University of Toronto, the report concluded in July 2008 that
little is known to assess the overall human and environmental risks posed by the
introduction of nanomaterials and nanoproducts into society. Available risk
strategies applied to nanomaterials should do the trick, though.
The report examined likely routes of exposure
and different categories of exposure: workplace, consumer use and exposure due
to the nanoparticles being in the environment e.g. in combusting fuel, in the
air, water, soil. The gaps in techniques for measuring and monitoring were
explored. Because there are also natural nanoparticles, overestimations of the
impact of engineered particles may also result. Among the conclusions of this
report:
- It is unlikely that a general measurement is
applicable to all nanomaterials. [GL notes
that this is not surprising since nanotechnology isn't a single material,
process, product, or thing]
- Current measure of human and ecological risk
assessment frameworks can be applied by nanomaterials but need new ways of
measuring exposure, dose and response.
- Effects over the lifecycle need to be
considered. e.g. just as scientists are finding polar bears with
brominated flame-retardants in their blood so the lifecycle of the
nanomaterials needs to be linked to potential exposure.
- It is important for industry to address the
uncertainty as the public might not have confidence in the technology reducing
sales and resulting in greater regulation. A higher level of precaution,
regulation and transparency to the public might help the companies involved in
nanotechnology otherwise vulnerable to future public lack of
acceptance.
- Nano-containing products enter Canada with
little regulatory review.
- Nanomaterials Management includes: US EPA
Voluntary Materials Stewardship Program; EU Code of Conduct for Nanoscience
and Nanotechnologies Research and the UK Voluntary Reporting.
The report is full of terminology highlighting
the uncertainty: "inadequate data", "given the current state of knowledge",
"dearth of research strategies that lay out a clear roadmap to filling essential
knowledge gaps, especially in the Canadian context" and “nanomaterials may be
small but the diversity is vast." Government needs to direct funding for risk
assessment and risk management including overcoming barriers due to proprietary
information.
The members of the Council of Canadian
Academies are the Royal Society of Canada: The Academies of Arts, Humanities and
Sciences of Canada; the Canadian Academy of Engineering; and the Canadian
Academy of Health Sciences. None of them are in any way ‘alarmist’
organizations.
One member of the expert panel was Robert
Slater, Adjunct Professor, Carleton University and President, Coleman, Bright
and Associates (Ottawa, ON) who GL and many people know from his long service in
senior positions at Environment Canada.
GL thinks it good that both the AMEC-funded
book (see separate article) and this report considered the likely sources of
exposure throughout the lifecycle of the nanomaterials/products: production and
manufacture, use e.g. by the consumer of cosmetics or other products, and post
consumer.
The public wouldn't know that the Health
Minister asked the Council of Canadian Academies to review the safety of
nanomaterials. Our search on Health Canada's web site using the title
of the report there are zero results. In fact, on Health Canada's A-Z index
there is no nanotechnology as a topic.

US: NATIONAL
NANOTECHNOLOGY INITIATIVE
In the US, a report on the budget requests for
nanotechnology was published as a supplement in the President's 2010 Budget
Request to Congress in May 2009. Twenty-five federal agencies are involved. The
request for Fiscal Year 2010 of $1.64 billion brings the cumulative investment
in the National Nanotechnology Initiative since 2001 to $12 billion.
Nanotechnology is huge; it has already provided tools. processes and products
but the report says, "It is the enormous potential of nanotechnology to lead
revolutionary, paradigm-shifting advances that warrants continued public and
private investments."
Environment
health and safety
One of the four goals is responsible
development of nanotechnology. Cumulative investment in Environment Health and
Safety is $350 million, mostly since 2005. EHS requests for 2010 are $88 million
which will cover increased research on the type and amount of nanomaterials in
biological systems, the environment and the workplace. Some of the comments
were:
- EPA's program has found that coating the
particles with a layer of certain materials changes toxicity. Rice University
researchers have found iron oxide nanocrystals can remove 98-99% of arsenic
from drinking water.
- FDA is reviewing how to regulate food, food
additives, nutritional supplements, cosmetics, drugs, medical devices and
biologicals. New tools are needed including detection methods and identifying
and characterizing nanomaterials in terms of toxicity, biocompatibility,
exposure assessment, formulation and suspension media which affect
properties.
- National Institute for Occupational Health
and Safety aims to control occupational exposure to fine and ultrafine
titanium dioxide, improve sampling and analysing for workplace exposure and
controlling airborne exposures; develop recommendations for controlling
occupational exposure to carbon nanotubes and find and address gaps in
information on sampling, analysis, exposure assessment, instrumentation and
controls; long term health effects, explosive potential; establish guidance
for engineering controls and protective equipment and safe handling of
nanomaterials
- Households are exposed to both nanoparticles
released by common kitchen appliance. Engineered nanomaterials can be
transferred up the lowest levels of the food chain from single-celled
organisms to multi-celled ones. The amount is low and nanomaterials don't
concentrate in higher-level organisms. NIST has developed techniques to purify
carbon nanutobes and apply a method to enable uniform testing for EHS and
commercial applications a key step to assessing hazard to biological
systems.
The US (as is Canada) is working with the OECD
on an international level. EPA is testing 14 nanomaterials on 59 environmental
end points.

PROPOSED
CANADIAN REGULATORY FRAMEWORK FOR NANOMATERIALS
In 2007, Environment Canada and Health Canada
posted a proposed regulatory framework for nanomaterials under the Canadian
Environmental Protection Act, 1999. Two phases of implementation were
outlined:
Phase 1 (started fall 2006)
1. Continue work with international partners
to develop scientific and research capacities (OECD, ISO).
2. Inform potential notifiers of their
regulatory responsibilities under the current framework.
3. Develop initiatives to gather information
from industry on the uses, properties, and effects of
nanomaterials.
4. Consider whether amendments to CEPA 1999 or
the NSNR would be needed to facilitate the risk assessment and management of
nanomaterials
Phase 2 (starting 2008)
1. Resolution of terminology and nomenclature
by ISO TC229.
2. Consider establishing data requirements

3. Consider the use of the Significant New
Activity (SNAc) provision of CEPA 1999 to require notification of nanoscale
forms of substances already on the DSL."
A search on the CEPA Registry didn't outline
any further regulatory or consultation process and while the priorities of both
departments for 2009-2010 mention nanotechnology in connection with emerging
technologies, a search on both websites did not help us learn about any progress
on this proposal. As far as GL has been able to determine, CEPA-related activity
on nanomaterials has been reduced to invisible nanoscale.

CANADA
DOMESTIC SUBSTANCES LIST
In Canada, substances that are not on the
Domestic Substances List require notification and assessment, as prescribed by
regulations, before they can be manufactured in or imported into Canada. In
2007, Environment Canada issued a notice on the requirements for nanomaterials
(whether chemical or polymer) regarding the New Substances Program of the DSL.
Anyone who manufactures or imports a new substance exceeding a specified
regulatory trigger is required to provide a risk assessment of its potential
effects on the environment and human health. The notice includes:
- a definition of nanoscale , typically between
1-100 nanometers but some nanomaterials such as quantum dots, may have three
dimensions greater than 100 nanometers. Buckyballs have all three dimensions
smaller than 1 nanometer.
- If the substance is already on the Domestic
Substances List as a conventional substance and the nanoscale version has no
unique molecular arrangement, notification is not required, e.g. titanium
dioxide is on the list and there is no unique nanostructure so nanoscale
notification is not required. There are some exceptions for substances where
notification is required even if the DSL has them e.g. the proposed use is
defined as a Significant New Activity Notice.
- incidentally created or natural nanomaterials
do not require notification.
The Canada Gazette has a number of notices for
nanoscale substances, for example recently tungsten carbide.

ENVIRONMENT
CANADA: LINKING SCIENCE AND POLICY DEVELOPMENT
Dr. Alex T. Bielak, Director, Science and
Technology Liaison at Environment Canada wrote, "I enjoyed the most recent
Gallon and thought you might be interested in the latest my group has done by
way of work on strengthening links between science knowledge and policy/decision
making. My colleague Karl Schaefer was involved with Gail Krantzberg at McMaster
University and a student intern via the Science Horizons Program at seeing how
science figures in the scheme of things for Ontario's Conservation Authorities.
A synopsis is available at http://ec.gc.ca/scitech/default.asp?lang=En&n=1B75C5DC-1. We hope that the insights gained from this will help in
better targeting EC's science. Follow up work is ongoing with a second intern
now to explore further some of the interesting findings.
INTERMEDIARIES/RESEARCH INTERPRETERS
For policies to be based on science,
environmental research results need to be disseminated and implemented. In The
Strengthening...paper (see above) Bielak and co-author in a section on Canada
discuss a range of issues regarding research and the users of research but one
is communicating the results. While some researchers are willing and able to
communicate their results to potential science users, others are not for various
reasons such as unwillingness to take time away from research or inability to
translate the technical language to plain language accessible to policy makers.
GL notes that at one environmental science conference, the keynote speaker
begged scientists to quit concluding every research project with the statement
"More research is needed" and tell policy-makers what difference this particular
result makes,
Relevant to environmental research is the role
of intermediaries between the scientists and the science users. These people act
as translators and interpreters but in order to do a good job need to meet
certain requirements such as "background in science and policy; strong
interpersonal, written and oral communication skills; and the ability to develop
trust and understanding with both researchers and science users. Understanding
the science needs of program managers and policy makers is fundamentally
important." Bielak's paper discusses how many organizations e.g. government fund
research but allocate no money for the intermediaries whose role is to "serve to
compile and synthesize complex scientific information, highlight policy-relevant
information, make linkages, and tailor information to specific
audiences."
While these papers are not specific to
business, GL suggests that businesses with heavy investments in science have
similar needs to communicate to policy-makers within their own company, to
investors, to government and to the public.

IEA: URGENT
NEED FOR ENERGY POLICIES FOR CLIMATE
The International Energy Agency released a
special early excerpt of the World Energy Outlook 2009 climate change analysis
for governments participating in the international climate change negotiations.
The full report will be published November 10. In the introduction to the
report, Executive Director Nobuo Tanaka writes that the report "delivers a
simple stark message: if the world continues on the basis of today's energy
policies, the climate change impacts will be severe." The IEA sets a 450
Scenario or 450 parts per million of CO2 equivalent. Higher than the 350 ppm
targeted by others, a number of scientists say that number is high and comes
with high risk. One effect of the recession, the financial crisis of the last 18
months, is that CO2 emissions fell in 2009 which helps to achieve the 450 ppm
"but only if the right policies are put in place promptly." The UN Climate
Change talks in Copenhagen in December are crucial to these policies. Fossil
fuel use must peak by 2020 and decline from then.
For OECD countries of which Canada is a
member, policies recommended are:
- an OECD-wide emissions trading scheme to
deliver emission reductions in power generation and industry.
- expand support mechanisms for end-use sectors
to encourage investment in energy efficiency in buildings and transport
- facility the transfer of low-carbon
technologies to non-OECD countries, through international sectoral agreements,
the purchase of carbon credits and other measures.

CO2 STORAGE:
IT'S NOT ROCKET SCIENCE, IT'S ROCK SCIENCE
A paper by another science interpreter
Edmonton Journal’s Graham Thomson explores not so much the direct economic costs
which are high but the problems, hazards, risks and hidden environmental costs
of large scale storage of carbon in saline aquifers Carbon Capture and
Sequestration CCS. The report is a good source of views on the subject but the
conclusion is that as yet, CCS is folly mostly because of the hazards it poses
for drinking water. Among some of the issues are:
- Power plants such as coal-burning facilities
already withdraw a lot of water some of which is returned to the lakes and
rivers. Power plants using CCS are expected to use 1/4-1/3 more water than the
same plant without CCS. Some areas such as the American southwest and
provinces such as Alberta and Saskatchewan don't have extra water.
- While Enhanced Oil Recovery is often offered
as an example that CCS works, EOR isn't CCS. In EOR, oil companies inject CO2
into depleted fields to extract more oil, The CO2 doesn't have to stay
underground for the long term and EOR is such a small scale to what would be
required for CCS.
- The number of sites suitable for CCS has yet
to be determined. Abandoned wells, faults and bad seals allow leaks.
- Leaks can pollute water as captured CO2 has
contaminants from the combustion process at the electricity producing plant.
Other toxics in CO2 may be produced by other large emitters such as cement
plants. CO2 and the pollutants may allow other toxics within the rock to leach
out, may escape as toxic gas or leach into groundwater. The pressure of the
CO2 in saline aquifers could force out the saline into drinking water
sources.
- The pressure of the CO2 can induce
micro-earthquakes, already documented for oil wells in the US and Canada.
These can cause fractures and more leaks leading not only to the release of
CO2 but more pollution of the water supply.
- Who 're you goin' call? Liability for the
legal consequences of most of CCS is yet to be established. The U.S. EPA has
introduced proposals for a new class of injection well – Class VI – specific to CCS which stipulates issues such
as site selection, monitoring, well construction and testing, decommissioning,
and the closure of the sites. In August, the US EPA began a new round of
consultations on its proposal for regulating geological storage of CO2. Robert
Page, TransAlta Professor of Environmental Management and Sustainability at
the University of Calgary, is quoted as saying that Canada has made little
progress compared to the US.
- While many regard the saline aquifer
reservoirs as waste places, they may not be so. They may be sources of
desalinized water and important mineral content such as silica, lithium, zinc,
and manganese.
GL still sees CCS as mostly a strategy for
those wanting to delay global action on climate change and those who want to
promote "clean coal" without being clean. That is not to say that CCS is useless
but it is certainly no magic bullet and cannot possibly reduce GHG levels to
something that the vast majority of scientists see as ‘safe’. But there is a
growing literature on CCS and on another technological approach that seems even
more far out, geoengineering, the idea of massive infrastructures such as
reflective kites. A number of these papers also urgently call for emission
reductions but are predicting that overshooting certain CO2 concentrations in
the atmosphere could be so dire that these almost-unthinkable and indeed
almost-impossible approaches have to be considered, tested for feasibility, and
implemented if possible even at horrendous costs.

BJORN LOMBORG:
ALWAYS LOOK ON THE BRIGHT SIDE OF THE STATE OF THE WORLD
John DeWilde, M.Eng., P.Eng., Senior Environmental
Engineer at PGL (Pottinger Gaherty Environmental Consultants) wrote, "I was
recently talking to my MP () about global warming. He was evasive and defensive
but used the book Cool It: The Skeptical Environmentalist's Guide to Climate
Change by Bjorn Lomborg as a reference for much of the conversation. I got
the book from the library and read it so I could be informed for the next
discussion. It was tough going. The book seems fraught with assumptions and
has blinders to many issues but I would love to hear your take on it. If you
have reviewed it already I’d love to read that."
GL: A few decades ago, we could buy almost all
the books published relating to business and the environment but no longer so
our gesture is not much of a statement but we made a deliberate decision not to
buy, read or review Cool It - a small boycott but having read his 2001 book it
seemed like a waste. It is an expression of disapproval of Lomborg's unorthodox
and unfounded claim to the scientific truth despite his obvious and
self-admitted ignorance. Gary Gallon, the founder and namesake of the GL, wrote
a whole issue in 2003 (GL Vol. 7, No. 1, January 11, 2003) focussing on
Lomborg's ignoring key issues, setting up straw men and knocking them down thus
reaching wrong conclusions.
Nature
journal's review
DeWilde's MP is not the only one who prefers
Lomborg's convenient misinterpretation of selected information to the complexity
and the uncertainties of science. Economist Partha Dasgupta, professor of
economics at the University of Cambridge, reviewing Cool It writes of how
much people have clung to Lomborg's view while "the world's foremost environmental
scientists expressed more than mere scepticism towards Lomborg's grasp of
their science." Dasgupta writes that when people learn about his field, ecological
economics, some ask him "And have you read Lomborg?" - implying "Why have
you thrown away so much of your working life?" But he says, things have changed
with Al Gore's film Inconvenient Truth and the Fourth Report of the Intergovernmental
Panel on Climate Change raising public concern.
The review points out that Lomborg's
cost-benefit seems to assume that we can just keep doing the same thing until
things get better. But the earth is a non-linear system. Going as high as 560
ppm concentration of CO2, as Lomborg suggests could cause irreversible natural
processes. While there is a possibility that the changes could be good at least
for some, the greater likelihood is that the effects could be disastrous. While
Lomborg thinks the Kyoto Protocol is a bad economic deal in the context of his
own limited scenario, it could be a very good deal indeed if some of the
scenarios projected by many of the world's climatologists turn out to be
reality. Lomborg's chief failing is that he doesn't deal with uncertainty; his
assumptions are based on arbitrary boundaries which if he is wrong leaves
humanity without insurance. Dasbupta concludes "Lomborg's seemingly persuasive
economic calculations are a case of muddled concreteness."

Lomborg errors
web site
More involved people than GL have been
challenging the credibility of Lomborg. Biologist Kåre Fog, Denmark writes a web site on Bjorn
Lomborg, He laments the media attention to Lomborg. He doesn't know to what
extent (indeed if any) Lomborg was influential in the US not signing on to Kyoto
Protocol or other delaying action on climate change. He talks about the Danish
Ecological Council posting a book showing the flaws and errors saying, "It was
available from June 2002. Unfortunately, it has received little attention so
far. It is strange to me that Lomborg´s book, which is full of errors and flaws
and not reliable, is sold in large numbers throughout the world, whereas a book
that corrects the errors and gives a more balanced view of the same topics, is
nearly completely ignored."

Lomborg's 2001
book: not good scientific practice
The Danish Committee on Scientific Dishonesty,
an almost unique committee established by the Danish government, reviews
complaints such as forging of data and plagiarism. Danish legislation stipulates
that DCSD’s chairman must be a high-court judge. Three complaints, two Danish
and one foreign, were filed about Bjorn Lomborg's 2001 book. The Committee
wasn't sure the book was science but it was presented as science. The ruling was
that the book was not consistent with good scientific practice.
Lomborg appealed to the Danish Minister for
Science, Technology and Innovation who asked for a review of the terms of
reference of the Committee.
The Committee in its 2004 report reviewed the
case and didn't seem to feel the need to retract or review any further. Among
the items in that annual report were:
- whether the book is science or general
debate. If intended to be evaluated as science, the report says, "the
scientific message had been so distorted that the objective criteria for
establishing scientific dishonesty has been met."
- whether the misleading of readers was
intentional. DCSD didn't find intent or gross negligence mostly because, "in
the preface of the book, the defendant had himself drawn attention to the fact
that he was no expert in environmental issues."
- the Ministry of Science delivered a ruling
which seemed to fault the DCSD for regarding the book as a scientific work and
in part of the concept of "good scientific practice." The DCSD report however
said any kind of review or renewed assessment "could not be expected to lead
to any result other than that set out in DCSD's decision of 6 January 2003. By
law, the DCSD cannot undertake an appeal if the "possibility of upholding the
complainant's claim is considered unlikely a priori."

Intermediaries
GL isn't discounting Lomborg due to his being
non-climatologist or even a non-scientist or lack of other credentials although
all of those are important depending on which positions one takes. We weren't
impressed with his 2001 book. Rather Lomborg is being judged as untrustworthy,
for conjuring up eco-conspiracies without providing evidence e.g. his assumption
that world environmental researchers including climatologists are either
willingly misleading or willy-nilly miscalculating their estimations of impacts
of human-caused impacts on the environment. If this charge of his had any basis,
his extraordinary ability for gaining media attention would surely ensure a
multi-million dollar advance by the oil companies for an expose of such an
eco-conspiracy. Somehow that book hasn't been written.
Perhaps it is timely that in another article,
GL discusses papers on linking science and policy sent by Alex Bielak of
Environment Canada. Bielak and co-authors report on the the role and
qualifications of intermediaries, the people who help to interpret, translate,
communicate or otherwise help decision-makers and the public use science. David
Suzuki who just won a prize for his work in raising awareness of climate change
is such an intermediary*. Although Suzuki has a science background, like GL's
editor, his scientific expertise and recent publications are not on climate
change. Instead he interprets in ways which we here at GL see as generally
consistent with the scientific research to the public and any governments who
will listen. All of us, Lomborg, Gallon now deceased, GL's editor and Suzuki are
basically policy wonks when it comes to climate change and when expressing
opinions on science not within our training Without our own recent peer-reviewed
research, we can still speak to the policy implications of science but we have
to be careful. To use an analogy in medicine, we could comment on fair access to
health services but have to be careful not to have the hubris to tell the
surgeon where to cut with the scalpel. Lomborg's hubris has no such limits when
it comes to mending the damage to another kind of patient, the global
environment.
* Among the recognition of the Right
Livelihood Award, described by sone as the alternate Nobel prize, Suzuki is
honoured for his "lifetime advocacy for the socially responsible use of
science."

US FEDERAL
DEPARTMENTS TO SET ENVIRONMENTAL EXAMPLE
US President Obama signed an Executive Order
setting environmental goals for federal agencies including to:
- set a 2020 greenhouse gas emissions reduction
target within 90 days
- increase energy efficiency
- reduce fleet petroleum consumption
- conserve water
- reduce waste
- support sustainable communities and
- leverage Federal purchasing power to promote
environmentally-responsible products and
technologies.
According to the press release, the federal
government occupies nearly 500,000 buildings, operates more than 600,000
vehicles, employs more than 1.8 million civilians, and purchases more than $500
billion per year in goods and services.

DOE FAILS TO
SET-BACK TEMPERATURE CONTROLS.
It is possible that the President’s order that
federal departments should set an example while also saving taxpayer money might
have had a push from an audit of the Department of Energy DOE. The audit was
entirely on how the DOE conserved energy by using setback controls, both
mechanical and software to decrease the temperature difference between outside
and inside during non-working hours. The inspector general audit reported that
DOE is supposed to lead the country on energy efficiency and provide direction
for smart, efficient energy management. DOE didn't set back the thermostats in
over two-thirds of its buildings even though the department advised consumers
and businesses to do so.
As well as not using setbacks where they were
available, the Department also let a number of controls deteriorate so setback
was impossible and despite expanded leasing of space, failed to require setback
capability in leased buildings. The report also lists prior audit reports
showing how the department wastes energy.

NOBEL: CHANGE
OF CLIMATE AND CLIMATE CHANGE
Extract from the Citation of The Norwegian
Nobel Committee when awarding the 2009 Nobel
Peace Prize to President Barack Obama:
The Norwegian Nobel Committee has decided that
the Nobel Peace Prize for 2009 is to be awarded to President Barack Obama for
his extraordinary efforts to strengthen international diplomacy and cooperation
between peoples. The Committee has attached special importance to Obama's vision
of and work for a world without nuclear weapons.
Obama has as President created a new climate
in international politics. Multilateral diplomacy has regained a central
position, with emphasis on the role that the United Nations and other
international institutions can play. Dialogue and negotiations are preferred as
instruments for resolving even the most difficult international conflicts. The
vision of a world free from nuclear arms has powerfully stimulated disarmament
and arms control negotiations. Thanks to Obama's initiative, the USA is now
playing a more constructive role in meeting the great climatic challenges the
world is confronting. Democracy and human rights are to be
strengthened.
EarthShastra
Amit Bhattacharya's EarthShastra blog in the
Times of India congratulated Obama on the prize and then asked him to deliver on
the promise, to repay the debt the US owes the world. He wrote, "The US has been
the single biggest CO2 emitter since around 1915 (when it overtook Europe). Its
cumulative share in human induced carbon emissions currently stands at around
28% (World Energy Outlook 2009) - in other words, the US is responsible for
almost one-third of the CO2 emitted by burning fossil fuels since 1890.
Scientists say much of this carbon is still in circulation and causing global
warming.
That's a tremendous debt US owes the world.
Yet the US continues to tie any CO2-reduction commitments to actions taken by
China and India, countries that started developing only in the last 20-30
years."
