Canadian scientist links fish deformities to oilsands and American spills

David Schindler of the University of Alberta has written an open letter to two federal cabinet ministers pointing out the recent research findings from scientists as far afield as the Gulf of Mexico.
"Given the parallels in the cases from various locations, it seems likely that some chemical or suite of chemicals in crude oil is causing the malformations," Schindler wrote.
He's proposing that Canada take the lead in researching the issue by isolating the various chemical compounds and introducing them to fish stocks in a controlled setting.
And Schindler says the federal Experimental Lakes Area - which has been shut down by Ottawa for a savings of about $2 million annually - is the ideal natural laboratory for the work.
In a letter Wednesday to Fisheries Minister Keith Ash-field and Environment Minister Peter Kent - copied to a number of U.S. scientists and some news media - Schindler praised the monitoring work of government scientists in the Athabasca River.
But he said such monitoring can't possibly determine which chemicals may be affecting aquatic life due to the "complex chemical soup" found downstream from industrial oilsands development.
What's required, the scientist said, "would be whole ecosystem experiments where small amounts of selected chemicals are applied to whole lakes, and the effects determined on several key species in the food chain."
It's tailor-made for the federal Experimental Lakes Area in northwestern Ontario, a remote region of 58 pristine lakes that have been used since 1968 for groundbreaking freshwater studies on everything from nutrient-loading and mercury exposure to acid rain.
The Harper government announced last year it was closing the world-renowned facility as a cost-saving measure - although insiders say the operating cost of the facility is only $600,000 annually, of which a third comes back in user fees.
Fully funded independent researchers have been refused access to the site to continue their research this summer, although Ottawa is in negotiations with the province of Ontario and other parties to transfer management.
Linking the closure of the Experimental Lakes Area - a cause celebre among Canada's scientific research community and environmentalists - with oilsands pollution is a potentially toxic political mix for the government.
Activists have already claimed climate-change research at the ELA is the real reason the Conservatives closed the facility.
A spokeswoman for Ashfield did not directly address Schindler's proposal when reached for comment, but said in an email "the government continues to actively work toward establishing a new operator for the ELA site so that research there can continue."
Erin Filliter added that "freshwater science continues to be conducted across Canada at multiple facilities which more than adequately meets the needs of government research."
Similarly, Rob Taylor at Environment Canada said by email that "Minister Kent is very engaged in the environmental monitoring of the oilsands region." "The Canada-Alberta joint scientific monitoring program has been put in place to study any impact on air quality, water quality and biodiversity," said Taylor.
