The average Canadian has more than hockey in his blood; there
are also flame retardants, stain removers, heavy metals, PCBs
and volatile organic compounds, says an environmental group. Blood
and urine tests of 11 volunteers from Saltspring Island, B.C.,
to St. John's, NL, found scores of toxic chemicals suspected of
causing everything from cancer to learning disabilities, says
a report by Toronto-based Environmental Defence.
On average, each of the volunteers showed blood contamination
by more than 40 compounds, as well as urine contamination by a
number of pesticides. Environmental Defence says it's the first
nationwide study of blood and urine contamination in Canada, although
similar results have been obtained in the United States and Britain.
Despite the small sample size of the study the results reflect
a national problem, said Sarah Winterton, program director with
Environmental Defence, who had her own blood tested for the study.
She noted the 11 volunteers came from different parts of the country,
different types of communities, different ethnic backgrounds,
professions and age categories. "It's not like we all had
dinner together and had blood poisoning the next day," said
Winterton in an interview. "The only thing this group of
people had in common was that they live in Canada."It's a
glimpse of what everybody has in them."
Volunteers included B.C. wildlife artist Robert Bateman, St.
John's filmmaker Mary Sexton, and David Masty, chief of the Whapmagoostui
First Nation in northern Quebec. Masty had the highest levels
of mercury contamination despite living far from heavy industry.
Rick Smith, executive director of Environmental Defence, said
the results underline the need for tighter regulation on toxic
chemicals under the Canadian Environmental Protection Act (CEPA).One
of the few bits of good news in the report is that PCB concentrations
were much lower in young volunteers, which he attributed to the
PCB ban imposed about 10 years ago.
The study notes the number of new cases of cancer in Canada has
increased 54.4 per cent since the 1980s, while cancer deaths have
increased by 43.4 per cent. Although researchers often blame rising
cancer incidence on Canada's aging population, data show incidence
has increased among Canadians aged 20 to 44, says the report."The
types of cancer most common among this age group differ from those
among older people, which suggests that risk factors other than
age may be responsible for certain types of cancer.
"Among the study's recommendations:
-Virtual elimination of all releases of carcinogens to the air
and water by 2008.-A ban on brominated flame retardants.
-Expanding CEPA to cover chemicals used in consumer products,
not just those released to the environment.
-Requiring industry to prove the safety of its chemicals before
they are introduced, rather than testing them for toxicity after
they are in use.
The blood and urine tests were conducted by Centre de Toxicologie,
Institute National de Sante Publique du Quebec and Accu-Chem Laboratories
of Richardson, Texas.
