ABOUT THIS
ISSUE
We devote most, but not all, of this issue to
the serious problem of endocrine disrupting substances in our water. In November
2008, GL's editor and associates attended the Society of Environmental
Toxicology and Chemistry SETAC conference in Tampa, Florida. While scientific
research reported is still ongoing on industrial pollution, much scientific
attention was on emerging contaminants such as pharmaceuticals and personal care
products some of which are also endocrine disrupting chemicals EDCs which
present challenges to scientific research. In this issue, we discuss a couple of
the SETAC presentations, present a historical overview from the US National
Research Council on the issue and touch briefly on some of the other stories on
this vast and growing scientific and commercial literature.
Our editorial addresses the question of
environmental priorities, or lack thereof, in government and activist agendas.
In our last issue, we suggested that defining the Sins of Greenwashing might not
be the most helpful tool for encouraging greening of the marketplace. We
received a response from TerraChoice which we publish below. Dianne Saxe has
provided a column on James Lovelock’s recent presentation in Toronto. A reader
in Uzbekistan has drawn our attention to ongoing work on dryland sustainable
agriculture in that region and Dr. Peter Victor has written on “Bigger isn’t
Better” in relation to the economy.
Next issue we plan an update on green energy.
Meanwhile, we hope you find this acronym-filled issue (truly, we do try to
reduce the use of acronyms and to explain them before first use!) to be of
interest. We encourage your letters and comments.

PRIORITIES OR
ENVIRONMENTAL PATSIES?
Recently quite a few people have been asking
why governments are putting priority on such relatively trivial items as BPA in
baby bottles, shopping bags, and banning of seal products while making far fewer
big announcements about such major issues as endocrine disruptors, effective
waste reduction, and climate change. Why are governments cosying up to the
environmental NGO community and ignoring the scientists and green businesses
that offer in depth, and often alarming, analysis of the state of our climate,
our air, our water, our fisheries, and so on?
GL fears that the reason is that some of the
more high profile environmental groups are providing governments with instant
gratification on minor issues while backing off on those issue that truly
threaten the survival of species, including the human mammals. What government
could possibly resist the opportunity for such kudos as “Listing bisphenol A as
toxic is a tremendous step towards protecting Canadians from this harmful
chemical and we congratulate the Prime Minister and Ministers Clement and Baird
for this decision”?* Meanwhile, messages about the devastation that is now
expected by such respected advisors as Nicholas Stern to come from climate
change are almost totally ignored.
GL was most recently alerted to this
phenomenon of giving priority to the relatively unimportant by a series of
articles about the state of the Great Lakes that appeared in the Hamilton
Spectator. In those articles it was noted that the state of the Great Lakes has
almost completely dropped off the agenda of the Canadian and Ontario
governments. The question was why?
Our view is that the answer to the Great Lakes
question, as well as to many other major environmental questions, includes a few
realities:
• environmental
groups in Canada are no longer making water quality in the Great Lakes a
priority issue. Indeed, at least one major group that claims an environmental
agenda, the Council of Canadians, has made Great Lakes water quantity a higher
priority than water quality.
• almost
every press release, whether from an NGO or from a government, starts by telling
us what tremendous progress has been made on cleaning up the Great Lakes. The
facts tell otherwise but few of the major spokespersons have the intestinal
fortitude to explain that, while a few parameters indicate improvement, most of
the major indicators suggest that, overall, Great Lakes water quality continues
to pose a major threat to all those species that rely on it. By emphasizing the
tiny steps forward, governments have created a climate in which the fact that we
are taking many large steps backwards go almost totally ignored.
• Canadian
governments have cut back on research and collection of data. With less data and
few researchers the issues have disappeared. What a terrible message that sends,
encouraging cutbacks to research and data collection by those politicians that
want to reduce government action on the environment.
• Great
Lakes water quality has been found to be a tremendously complex issue. Like
governments, many environmental groups want quick hits and much press to support
their fundraising efforts. More important long-term issues are too expensive and
too technical for the political agenda of most activists.
We recognize that small steps can add up and
that every small step will bring us closer to the achievement of the
environmental goals to which most Canadians aspire. At the same time, we suggest
that spending time and government effort on the smallest of the small steps,
such as the issue of shopping bags, is taking valuable time and attention away
from the big issues that threaten major harm to humans around the
world.
Next year will mark the 20th
anniversary of the day when McDonald's withdrew polystyrene packaging from all
of its restaurants. The move, which was widely heralded, did nothing for the
environment. Indeed, arguably, it set back recycling efforts, contributed in the
wrong way to climate change, and gave lots of people an unwarranted good feel
about the environmental progress that they believed society was making. Note
that by 1990 the CFC problem, which was a serious problem in earlier polystyrene
foams, had been resolved so the withdrawal of polystyrene packaging served only
to remove a highly recyclable package for which a recycling program had been
developed in favour of a non-recyclable coated paper package which is still not
being recycled almost 20 years later.
GL encourages informed individuals to start
raising their voices against some of the trivial solutions being given such high
priority by governments and by environmental groups. Banning the sale of bottled
water in public spaces will not save the world. Indeed, some of the reaction,
such as larger sales for sweetened and carbonated beverages and use of reusable
but short life containers, will only make things worse. A Lake Simcoe management
plan, released last week may help Lake Simcoe [see a future issue for our
analysis] but will not itself do anything for the other 31,751 lakes larger than
three square kilometres in Canada. Why cannot Ontario develop a management plan
for the Great Lakes or for all lakes in the province.
It is time we started to focus more on the big
picture and less on the tiny solutions that give politicians and environmental
groups good press and a good feel but which almost completely ignore the real
threats to the environment which sustains us.

PHARMACEUTICALS AND PERSONAL CARE
PRODUCTS
****************************************************
INTRODUCTION
While the theme of this issue is
pharmaceuticals and personal care products , we shouldn't forget that these are
just part of what we as humans are doing to harm health and the environment: we
need a balanced approach which seeks to address the overall impacts of our
chemical use.
One of the presentations at the 2008 SETAC
annual meeting reported, for the first time, finding measurable concentrations
of a human pharmaceutical, the tranquilizer diazepam, in marine fish tissue.
Other research on potentially endocrine disrupting compounds in the southern
California coastal area finds legacy organochlorine pesticides (long banned in
commerce), PCBs, current pesticides, pharmaceutical and personal care products,
commercial chemicals, antifouling paints from ships, flame retardants and
nonylphenols. Some were found widely distributed in sediments, fish and marine
water, while others occur only in one or a few locations.
The detection of chemicals in the environment
and in the human body is usually a cause for further investigation, and even
concern but not always alarm. Some chemicals are a hazard but the risk may not
be high. Others may be indicators of significant risks.
Although the presence of the endocrine
disrupting chemicals in waters has been widely reported, a framework for
assessing the ecological risks of the EDCs is still lacking. One proposal at
SETAC was to relate the potency of estrogen-like active pharmaceutical
ingredients as a ratio to 17 -ethynylestradiol. This relative potency would then
be converted to a predicted no (adverse) effect concentration for aquatic life
proportional to that of the estrogen.
Excreted estrogens are considered to be the
most serious contributors to the aquatic concentration of estrogenic compounds.
It used to be believed that some forms of estrogen were inactive but it now
appears that these may be reactivated by interaction with chemicals and
microorganisms in the environment. GL notes that our (non-resident) population
expert Albert Bartlett, University of Colorado Professor Emeritus, wrote to us
to ask whether Elizabeth May and Zoe Caron's Global Warming for Dummies
discussed population (it did but only briefly) but here is an issue where
contraception controlling population is presenting a potential serious
risk.

NON-POINT
SOURCES OF POLLUTION OF INCREASING IMPORTANCE
Alan Kolok of the Aquatic Toxicology
Laboratory at the University of Nebraska at Omaha wrote recently about the
finding of eggs in male smallmouth bass in the Potomac River. He suggests that
"This phenomenon now poses one of the most important water quality problems of
our time." Despite five years of research it has not been possible to identify
the chemical compounds responsible. Although lab results indicate that certain
chemicals in water can cause intersex fish and other animals, in the environment
the link is still missing.
Kolok identifies changes from the past
approach to chemical pollution:
•
point sources usually, industrial pollution, were identified in the past as
causing pollution. Legislation such as the Clean Water Act and Safe Drinking
Water Act provided pressure for industry to stop the more blatant
pollution.
• the
levels of pollutants causing the effects are at much lower concentrations, some
of which a few years ago would not even have been detectable.
• in
the past, acute toxicity or lethality was key but endocrine disrupting chemicals
may not be very toxic but have chronic developmental or reproductive effects,
that is the effects are at the cellular level. Kolok writes, "This signal mimicy
and inappropriate pattern development can occur at astonishingly low exposure
concentrations, and can lead to bizarre changes in development, such as ovarian
follicles within the testes of male fish."
• Different
animals are affected differently so for example, fish are several orders of
magnitude more sensitive to estrogens than invertebrates.
While in the old pollution research,
scientists could check the end-of-the-pipe of the factory, this pollution is
much less visible but "an insidious trickle of effluent from a large number of
sources." Each compound may change into different metabolites, each having its
own environmental impacts as well as interacting with other compounds. Kolok
suggest that what is needed is:
• technical
innovation for better and cheaper assessment of the pollutants.
• public
awareness.
• political
will to deal with the much more difficult to solve problems than of
yesterday.

OTHER SOURCES
OF EMERGING CONTAMINANTS
Kolok (see above) was co-author of a number of
presentations at SETAC. Tests at the outlets of Wastewater Treatment Plants at
six small Nebraska cities concluded that WWTP effluent contributes significant
levels of estrogens to Nebraska’s surface waters. Caged minnows exposed to this
effluent have the greatest quantities of estrogen compared to fish at other
sites. Caffeine was also found almost everywhere, even in remote areas.
Growth hormones used in cattle have raised
concern about cattle feedlot runoff. Caged minnows were placed on the Elkhorn
River watershed where there are many feedlots. Female minnows experience reduced
expression of vitellogenin and estrogen receptor, indicators of defeminization,
compared to females in reference locations. But whether these reduced
expressions affect reproduction hasn't been established yet.

HISTORICAL
PERSPECTIVE: US NATIONAL ACADEMY OF SCIENCE REPORT
Public pressure in the 1990s led the US
Environmental Protection Agency, the Centers for Disease Control and Prevention,
and the Department of the Interior to request the National Research Council to
scientifically review the effects of environmental contaminants known as
endocrine disrupters on human health and on wildlife including fish. The
Committee on Hormonally Active Agents and the Environment was set up in 1995 and
found it a long and difficult process to produce its report, which was finally
published in 1999. There were problems defining in an unambiguous way what
"endocrine disruptors" were. Because disruptors implied a negative effect even
before the research was done, the Committee used the term hormonally active. The
most difficult area for reaching consensus was "in the area of reproduction and
development, including the issue of declining sperm production in human
populations."
Some synthetic chemicals in the environment
had adverse effects on wildlife mimicing the female hormone estradiol. In the
womb, human fetuses exposed to the synthetic estrogen diesthylstilbestrol (DES)
had adverse effects later in life. Mice similarly exposed as embryos had similar
effects which seems to indicate that lab studies were indicative of human
effects. Lab studies indicated that male and female rats, mice and guinea pigs
and female rhesus monkeys exposed during development to different concentrations
of HAAs such as DDT, methoxychlor, PCBs, dioxin, bisphenol A, octylphenol, butyl
benzl phthalate BBP, dibutyl phthalate DBP, chlordecone, and vinclozolin could
produce structural and functional abnormalities in the reproductive tract. It
was clear that at high concentration, HAAs affected wildlife and human health
but what was not clear was whether lower concentrations found in the environment
also caused the same type or extent of harm. Some effects may be due to other
chemicals or conditions. The Committee concluded that prenatal and postnatal
exposure to PCBs and polychlorinated dibenzofurans (PCDFs) due to contaminated
rice oil in Japan and Taiwan led to developmental defects but could not link
HAAs to other defects such as undescended testicles and testicular cancer.
Prenatal exposure to PCBs could lead to lower birth weight, shorter gestation,
deficits in IQ and memory and delayed neuromuscular development. There were many
studies on wildlife which showed reproductive and developmental anomalies due to
exposure to contaminants some of which are HAAs e.g. fish eposed to effluents
from sewage treatment plants, paper mills and polluted waters of the Great
Lakes. Effects include intersexes in trout exposed to sewage-treatment-plant
effluent STPE.
Estrogens, androgens, thyroid hormones and
many HAAs are assumed to be able to pass through cell membrances and interact
with receptors in the nucleus. Effects reported were "reproductive changes,
developmental defects, neurobehavioral abnormalities, immunologic deficits,
carcinogenesis and ecological effects."
The issues faced by the Committee were common
to all in the scientific community: limitations and uncertainty in the data,
determining appropriate sources of information, evaluating the evidence,
defining the chemicals with hormonal or antihormonal activity
CHALLENGES
A number of the challenges reported
were:
• while
there are observed effects, the question remains whether human sperm
concentration is really in decline. Sperm count is very controversial as some
data indicate this trend but it depends on whether different geographic regions
have difference in sperm concentration regardless of chemical
exposure.
• where
effects are clear such as developmental abnormalities, is the cause really the
HAAs. Many chemicals are in the environment and the variations of the
environment itself complicate conclusions.
• chemical
and other agents in the environment interact in multiple exposures so it is
difficult to assign causal action to specific chemicals. In the laboratory it
may be possible for the researcher to separate one potential causal agent from
all the other alternatives but outside the lab the complex biological processes
make it much more difficult. A harmful chemical may interact with many others.
The report says the Committee "has no illusion that the problem of how to
apportion cause among the members of a mixture of environmental chemicals will
soon be easily solved."
• chemicals
which have hormone-like activities also affect organisms unrelated to hormonal
activities.
• mechanism
of action between the HAAs and the biological outcomes is not well understood.
This doesn't mean that the reported effect is unimportant or unconfirmed but
more is needed about the direct and indirect effects of HAAs and between primary
and secondary effects. Mechanisms of actions are needed for both in vitro and in
vivo systems.
EXPOSURE TO
HAAS
HAAs can be synthetic or natural and exposure
can be involuntary or voluntary. Involuntary exposure for both humans and
animals can be by drinking contaminated water, breathing contaminated air,
eating food, or contacting contaminated soil although breathing in HAAs would
contribute a very small portion.
The Committee considered that humans
voluntarily exposed themselves to HAAs though use of cleaners, pesticides, food
additives, pharmaceuticals including birth control pills, herbal supplements,
cosmetics and pesticides.
Flavonoids in fruits and vegetables are HAAs,
especially high in soy beans. People consume about 1 gram of flavonoids a day
and these are related to lower incidences of some types of cancers such as
colon, breast, stomach and prostate. These natural estrogenic compounds could
have both anticancer activities and estrogen-related adverse effects. Compared
to estradiol estrogren, many of these natural estrogens or phytoestrogens are
many times weaker but their potency may depend on the conditions for binding to
the cell receptors. Some hormones are transformed into different oxidation
products. Steroids can interact with blood serum proteins changing the uptake of
HAAs. Legumes, oilseeds such as flax, nuts contain phytoestrogens. Even beer has
measurable concentrations of isoflavones. Concentrations can vary
widely.
Bisphenol A was detected in human tissue in
1995 from liquids in food cans containing a plastic coated liner. BPA was also
found in saliva leaching from composites and sealants in dentistry.
DDT is still used in developing countries.
PCBs are banned for production in North America but distributed due to
accidents, improper disposal or release from sediments or other environmental
sites or use.
Dioxins are HAAs which are unique in that they
are not purposefully made but are due to combustion of plant material and
byproducts of industries using chlorine. Forest fires, home wood fires, and
incineration create dioxins.
Alkyphenol ethoxylates APEs are used as
surfactants and detergents. The report discusses a range of potential HAAs which
may number in the tens of thousands as many chemicals have never been studied.

IJC: EMERGING
ISSUES FOR THE GREAT LAKES
The Great Lakes Water Quality Board advises
the International Joint Commission on restoring and maintaining the "chemical,
physical and biological integrity of the Great Lakes Basin ecosystem", the
US-Canada commitment under the Great Lakes Water Quality Agreement GLWQA.
Emerging challenges are making that mission more complicated. As well as
invasive species, the chemicals from pharmaceuticals and personal care products
and endocrine disrupting compounds are being examined for the proposed
renegotiation of the GLWQA in 2010.
About 70,000 commercial and industrial
compounds are produced, consumed and deposited into the environment and 1,000
new ones are introduced each year. New chemicals have effects of their own as
well as combining with already deposited toxic chemicals. Among the emerging
contaminants are: synthetic fragrances and musks, industrial and household
chemicals like flame retardants and stain resistant materials, veterinary drugs,
pesticides, genetically modified foods, vitamin and mineral supplements, food
additives, as well as pharmaceuticals and personal care products PPCPs. While it
used to be that most of the concern was at the manufacturing stage, ie
industrial pollution, these chemicals are released mostly during consumption and
disposal. These chemicals are not addressed in the GLWQA.
"Emissions" from medications are from human
feces and urine and from animal manure from animals treated with hormones and
drugs for speeding growth or dealing with disease. Other sources of
pharmaceuticals are dumping unused medications into the toilet or garbage and
sludge from sewage treatment spread on farm fields. Shampoos and soaps,
sunscreens, insecticides, hair gels, creams, makeup and perfumes are washed off
or thrown out to landfill to leach out into groundwater sources and eventually
to lakes and streams. Sewage treatment waste and agricultural runoff are big
sources of PCPPs into the aquatic environment. Sewage treatment plants do no
remove many of these substances which often become more active after
treatment.
The report outlines some of the impacts of
PCPPs:
• ingestion
by people and wildlife of excess hormones such as testosterone and estrogen
impact physical development and reproductive function.
• microbes
in water and soil adapt to antibiotics increasing risk of disease organisms with
antibiotic resistance.
• more
allergic reactions
• increased
negative impacts on sensitive people such as the very young, or the elderly or
those at certain stages such as pregnant women.
• adding
more to the already toxic soup of chemicals. The impacts of these mixtures is
still not well researched and represent risks many of them as yet
unknown.
STATUS
The US EPA set out a new approach in 2008 for
PPCPs which involves more research on:
• testing.
Since some of these chemicals may have effects at low concentrations; testing
protocols to detect both the chemical and the effects need
strengthening.
•
sources and effects in water.
•
policy development to regulate PPCPs.
No priority has been put on redesigning
pharmaceuticals to ensure that they degrade in the environment or use less toxic
chemicals.
In Canada, the Food and Drug Act covers both
pharmaceuticals and personal care products but while Health Canada conducts a
pre-market evaluation, there is no evaluation at the consumption and disposal
stage in terms of persistence, bioaccumulation or toxicity.

BIRTH CONTROL
FATAL FOR FISH
A popular presentation at the Society of
Environmental Toxicology and Chemistry SETAC meeting in Tampa in November 2008
was by Karen Kidd, Canadian Research Chair and Professor at the University of
New Brunswick.
She spoke to a slide show about a seven-year
whole lake experiment in northwestern Ontario, part of the 58 Experimental Lakes
in Canada which are used for research. It served to provide the answer to the
question of whether the laboratory studies of decreased reproductive success of
fish exposed to certain levels of EE2, the synthetic estrogen commonly used in
birth control pill. was valid in the wild fish. The lake was dosed with a
concentration of EE2 within the range of concentrations observed in treated and
untreated municipal wastewater. Fathead minnows have been adopted for toxicity
testing because they are widely distributed, easily cultured in the laboratory
and represents a large group of fishes. This fish normally has a lifespan of
about 4 years although only a few live beyond 2 years in this lake. Since they
don't spawn until the second year, most spawn only once. Two consecutive years
of reproductive failure spells catastrophe for the fathead minnow. Kidd told the
audience to watch carefully for Tristan shown in the slides as the person adding
the estrogen to the lake; we were to see him later in the
slideshow.
Within seven weeks of the addition of estrogen
in 2001, the fathead minnows began to show some changes compared to reference
samples from two reference lakes. The fish differences compared to the reference
samples were greatest during certain seasons ie the fall. In time, many males
were feminized to such an extent they were unable to reproduce and the females
also showed intersex features. By the fall of 2002, the fathead minnow
population collapsed. Although a few small minnows were still caught, they were
nearly extinct. The longer living dace in the same lake were not threatened to
the same degree. Lifespan and other factors may be important to the risk of
exposure to estrogens and estrogen mimics. Kidd suggests that while the
short-lived fish may be an indicator the chronic exposure of the longer-lived
fish would result in the loss of these populations too. The study concludes,
"inputs of natural and synthetic estrogens and estrogen mimics to the aquatic
environment in municipal wastewaters could decrease the reproductive success and
sustainability of fish populations."
Oh, and Tristan, the technical assistant
responsible for boating out into the lake and adding the estrogen: he was shown
feminized too with a wig and a dress.
One of the missions of the SETAC conferences
is to bring together scientists and policy makers in companies, government and
civil society. Some scientists do not find it easy to translate their technical
research into less-than-dry presentations, the topics in themselves are often
new and interesting even if that session is otherwise boring which is why many
sessions are surprisingly well-attended. Kidd, on the other hand, did a great
job of communicating the technical aspects while explaining what it meant, with
a touch of humour.

SWEDISH
PHARMACEUTICAL ENVIRONMENTAL INFORMATION
A voluntary Swedish pharmaceutical industry
initiative is classifying the environmental impacts of pharmaceuticals. Much of
the information in Swedish but some is in English. Three levels of information
are provided: 1. is for patients 2. and 3. give more detailed information with
3. the most applicable to the environmental risk assessment.
Level 1 rates the basic aquatic risk e.g. use
of this medicine results in insignificant environmental risk to high
environmental risk. Another category is for insufficient environmental
information available to assess risk.
Level 2 addresses whether the medicine will
degrade, bioaccumulate in aquatic organisms or whether the pharmaceutical is PBT
(Persistent, Bioaccumulative and Toxic) or vPVB ((very Persistent and very
Bioaccumulative), and again a designation for insufficient
information.
Level 2 is calculations related to risk
assessment including what % of the drug or its breakdown compounds is excreted,
what happens in sewage treatment plants, tests from ecotoxicity and degradation
tests, the names of species tests, (metabolites), CMR (Carcinogen, Mutagenic,
Reproduction effects) and endocrine disrupting potential and data analysis of
the risk.
Because they are not considered to be an
environmental risks, a number of pharmaceuticals are not documented including
vitamins, electrolytes, amino acids, proteins, and carbohydrates. Herbal
medicines and vaccines are also exempted.
Data is shared between companies where
possible. Predicted Environmental Concentration (PEC) is used as a basic measure
which uses a number of elements such as how many kg. are sold in Sweden for a
given year, what is the population of Sweden, volume of wastewater per capita
and day, dilution of waste water by surface water flow.

SAFE COSMETIC
CAMPAIGN
The US-based Environmental Working Group has
pushed for greater health and environmental improvements in personal care
products including operating a database on negative impacts through its
cosmetics database. It partners with the Campaign for Safe Cosmetics. According
to this group, a typical American consumer might use as many as 25 different
personal care products in a day with over 200 different chemical compounds.
Companies are encouraged to sign up to the Compact for Safe Cosmetics committing
to inventorying product ingredients and eliminating those linked to cancer,
birth defects and other serious health consequences and to bring safer, greener
production.

SCIENCE ON PPCPS: A POTENTIALLY BIG PROBLEM WITH A SOLUTION
A workshop on PPCPs was held in 2007 with
proceedings published as scientific assessment papers from Environment Canada's
National Water Research Institute.
It has been known for more than 20 years that
pharmaceuticals and personal care products are released into the environment but
only in the last decade have analytical methods been developed to identify and
quantify them in wastewater treatment plant effluents, surface waters, drinking
water, ground water, biosolids, farm manure and biota. Still the science about
exposure and impacts is rudimentary. This 2007 workshop was the third science
workshop on the topic following those in 2002 and 2004.
As well as pharmaceuticals, antibiotics and
personal care products such as synthetic musk fragrances widespread in Canadian
sewage effluent and waters, veterinary medicines and animal care products are
found in agricultural watersheds, according to Dr. Mark Servos, Scientific
Director of the Canadian Water Network. Wastewater treatment such as ozone and
filtration remove many of these types of compounds but are not widely used in
Canadian water treatment. Advanced treatments, also not used widely in Canada,
can remove many of these compounds.

TAKE-BACK
EXPIRED PHARMACEUTICALS-COLOMBIA
According to US-based law firm Beveridge &
Diamond, Colombia's Ministry of the Environment has issued a regulation which
will require take-back requirements for expired pharmaceuticals to be phased in
over a period of three years until 70% of the population have access.
Manufacturers and importers must develop management plans. Distributors and
retailers must accept return free of charge to the consumers and transfer them
free of charge to importers and manufacturers. Collection and disposal is
subject of hazardous waste rules. A Spanish version of the resolution is
provided.

TAKEBACK
PHARMACEUTICALS - CANADA
Post-Consumer Pharmaceutical Stewardship
Association (PCPSA) is a non-for-profit organization mandated with developing
harmonized approaches to medications return programs in Canada.
In BC on March 20, the British Columbia
Pharmacy Association and the PCPSA held a
medications return awareness campaign. In a
program which is a decade old, consumers are
asked to return unused medications to
drug-retail stores in BC so the unused and expired
medications can be disposed of in a safe way.
The stewardship initiative claims to have disposed of about 35,000 kg of
medication in 2008 up 53% since 2007. The collection containers were redesigned
to be larger and rectangular to reduce volume and fuel use in
transportation.
In Ontario, the the Municipal Hazardous or
Special Waste Regulation identifies pharmaceuticals, including natural health
products, as one of the category of obligated materials. The aim is to divert
the material through 3Rs stream (reduce, reuse, recycle) diverting them from
landfill by charging a fee to the makers and importers of the material. It is
expected the medications program will be implemented in early 2010. The PCPSA
says that the pharmacies should lobby for having a program run by the industry
so the medications are returned to community pharmacies for collection rather
than through hazardous waste days/depots as the return to store is seen as more
cost-effective ie cheaper.

MANUFACTURERS
VOLUNTARILY REMOVING PHTHALATES
The American Chemistry Council, an industry
group, issued a press release in April expressing concern that some
manufacturers have chosen to remove phthalates from fragrances even though there
is no science or regulatory support for that decision. The web site includes a
Phthalate Information Centre and information on endocrine
disruptors.
For example, SC Johnson known more for
housekeeping products but also selling skin-based pesticides and shaving gels,
has promised to phase out phthalates in fragrances particularly
DEP.

NEW COSMETIC
LAW FOR EU
In March, the European Parliament voted in
favour of a new version of an act on cosmetic products. Cosmetics legislation is
essentially a version of chemical law as cosmetics are chemical preparations. It
requires:
• prior
notification, safety assessment and labelling of nanomaterials. Each such
ingredient will have nano in brackets after its name. A catalog of all
nanomaterials used in cosmetic products as well as foreseeable exposure
conditions will be maintained by the EU.
• new
provision for traceability along the supply chain.
• safety
assessment based on the intended use as well as the systemic
exposure
• traces
of prohibited substances will be allowed but only if unavoidable under good
manufacturing practices. Prohibited substances include CMRs (causing cancer,
mutagenic and reproductive effects) and three phthalates DEHP, DBP and
BBPs.
• country
of origin on all imported cosmetics
• tightening
up on claims about characteristics and functions
• member
nations are expected to perform checks on products including physical and
laboratory checks based on adequate samples.
• a
channel for communicating adverse effects e.g to health professionals,
distributors, etc.
To come into force 42 months after the end of
the date of publication in the European Journal.
Environmental safety is not addressed by the
recast of the Cosmetics Directive per se but the REACH regulation requires
suppliers of chemicals used as cosmetic ingredients to supply cosmetic
manufacturers with information on environmental hazards:
• if
the substance is produced in quantities of over 10 tonnes per year per
registrant, a chemical safety assessment including environmental risks must be
performed and communicated by the cosmetics manufacturers.
• downstream
users of the ingredient must apply the recommended risk- reduction measures of
the manufacturers.
• substances
under REACH may be restricted or require an authorization process to address
environmental safety

US EPA:
ENDOCRINE DISRUPTORS TO BE SCREENED
In 1996, Congress as part of the Food Quality
Protection Act required the US Environmental Protection Agency to screen
pesticide and other contaminants for their endocrine disrupting potential. Along
with the OECD and OECD member countries, the US EPA developed a Endocrine
Disruptor Screening Program. Many of the tens of thousands of chemicals on the
market could be hormonally active. In April 2009, the EPA published the list of
initial Tier 1 Screening chemicals consisting of 67 pesticide active ingredient
and high production volumes pesticide inert ingredients. This doesn't mean the
chemicals are endocrine disruptors. Among the chemicals are some phthalates used
in personal care products. For example, dibutyl phthalate is used in some nail
polishes although some companies have phased it out.

HENKEL:
PRODUCT SUSTAINABILITY PROFILE
Henkel published its first Environment Report
in 1992. In its latest report, the Germany-based company says it is increasing
the use of ingredients from controlled organic crops in toiletry formulations.
Products are formulated for biodegradability and "we have set ourselves the
target of raising the proportion of readily biodegradable ingredients in our
soaps, shampoos and shower gels from the current 65 percent to 80 percent by
2012."
More products are being formulated for "a high
sustainability profile", for example no synthetic colourants, perfume
ingredients, polyethylene glycols, or mineral-oil-based paraffin oils. Some
products such as toothpaste and liquid soaps are third-party certified by
ECOCert to meet other ecological criteria.

CITY OF
MONTREAL - OZONATION TO REMOVE PHARMACEUTICALS
The 2009 budget for the City of Montreal
includes the installation of the new ozone treatment system for treating
wastewater discharged into the river
Researchers from Environment Canada, the City
of Montreal and the University of Montreal were involved in pilot projects using
different forms of treatment, using ozone, performic acid and UV-radiation
disinfection processes at the Montreal wastewater treatment plant. Before
disinfection, residues of a number of pharmaceutical products were found
including salicylic acid, clofibric acid, ibuprofen, naproxen, triclosan,
carbamazepine, diclofenac, and 2-hydroxy-ibuprofen at different concentrations.
Specific ozone doses eliminated more than 50% of these with higher removal rates
at higher doses of ozone. UV radiation often removed less than 10% although
there were better rates for diclofenac and triclosan. Irradiation which improves
bacteria removal did little to deal with the pharmaceuticals and performic acid
had poor removal rates for pharmaceuticals. How the by-products created by each
of the treatment methods affects health and the environment has yet to be
studied. The various chemicals and processes used in the current water
treatments such as chlorine also create by-products some of which are considered
potentially serious contaminants of water.

LETTER TO THE
EDITOR
Dear Editor, thanks for your recent coverage
of this year’s “Sins of Greenwashing” study.
As you might expect, we disagree with all or
most of your representations about and criticisms of the study. Nevertheless,
these are important issues and we welcome the debate. Most importantly, I
suspect we can agree on these two thoughts: Support for companies that are
trying to offer “greener” products is an important thing; consumers have a
tremendous power to change the world. And, encouraging ever greater standards
and transparency in environmental claims is important to encouraging ever
greener innovation and progress toward sustainability. We’re confident we share
those objectives with you and so, though we might disagree with your analysis
and conclusions in this case, we’re happy that the issue attracts your
attention.
Many thanks.
Sincerely,
Scott McDougall

GUEST COLUMN -
JAMES LOVELOCK AND THE CLIMATE “PHONY WAR”
by Dianne Saxe
Renowned scientist James Lovelock gave a
powerful speech in Toronto today. Lovelock argues persuasively that we are
already headed to huge, irreversible temperature changes, which will massively
disrupt human society and populations. These changes will be far greater and
faster than those predicted by the ?Intergovernmental Panel on Climate Change,
just as actual changes in sea level, temperature and ice have repeatedly
outstripped those predicted by the IPCC. And much, much greater than those
predicted by Al Gore. How will people react? (Gwyn Dyer says, “Climate
Wars”.)
In the face of this crisis, Lovelock calls for
an urgent shift to energy conservation, renewables and nuclear energy, less meat
consumption and a huge effort to create and bury charcoal. But even if we do all
of these things, disruptive temperature rises are inevitable, likely in sharp
jumps. Lovelock predicts food shortages and huge migrations to northern regions,
such as Canada. It’s like the “phony war” in 1939, he says; everyone knows the
disasters are coming, but no one is doing anything effective about it. When we
do decide to act, we will bitterly regret these lost years.
The speech was organized by Corporate
Knights.

CONSULTATION
ON DRYLAND SCIENCE
Christopher Martius of Uzbekistan writes to
draw awareness to the first drafts of scientific analysis papers to support
decision-making at the UN Scientific Conference contributing to the world’s
fight against desertification and land degradation**. He oversees a program
promoting more profitable and more sustainable agriculture in the highly
degraded lands of Central Asia and the Caucasus, where the collapse of the
Soviet Union has led to the virtual disappearance of farm research and support
for natural resource management, improving crops and livestock and ensuring good
links between consumers and producers. Food insecurity and poverty are the
result.
For one month, from 28 May to 28 June 2009,
the first drafts of the white papers from the three Working Groups plus one
paper on a cross-cutting topic will be open for review by scientists and
stakeholders worldwide. To begin the review of the 80-100 page long papers,

PROSPERITY
WITHOUT ECONOMIC GROWTH
Peter Victor, author of Managing without
Growth, (see GL Vol. 13, No. 12, December 22, 2008 Peter Victor: Managing
Without Growth) wrote an op-ed piece in the Ottawa Citizen. The comments on the
Ottawa Citizen web site on the article were generally positive although one
comment suggested that a steady state economy on a planet with ever-growing
population could mean a downward spiral for each individual.
Victor also provides a link to a new UK report
by the Sustainable Development Commission SDC, the Government’s independent
watchdog on SD. Prosperity without Growth? discusses the drive in current
economic policy to return to growth which fuels environmental crisis and "social
recession", a growing gap between the wealthy and the poor. One fifth of the
world shares just 2% of the world's income. In the last 25 years, the global
economy has doubled but resource consumption has degraded an estimated 60% of
the world's ecosystem and led to the threat of global and catastrophic climate
change. Author of the report, Tim Jackson, Economics Commissioner of the SDC
said, "For millions in developing countries, growth is clearly still vital to
deliver basic standards of living and well-being. But, in developed countries
including the UK, well-being far from increasing prosperity, our debt-driven
consumption has created an unstable system which has put jobs and livelihoods at
risk, as well as damaging us psychologically and socially."
