This is the first really seriously negative thing that I have read about the Canadian Oil Sands. I'm not that worried about C02 - but mercury is really bad news.

But the study has not been released. It is also unclear how widespread the toxin is. Many mining operations have really nasty side effects. Coal mines, copper mines, etc..... A lot of what makes a modern society possible has some real consequences.

weird... methyl mercury is usually created from biological activity on elemental mercury, not an actual emitted substance
"Here we have a direct source of methyl mercury being emitted in this region and deposited to the landscapes and water bodies," Kirk said of samples the team took from snow and spring snow-melt. "So come snow-melt that methyl mercury is now going to enter lakes and rivers where potentially it could be taken up directly by organisms and then bioaccumulated and biomagnified though food webs." - Jane Kirk
in fact the pathway from elemental mercury to methyl mercury is well understood (Togwell Jackson, et al.), especially in newly formed reservoirs.
"Methylmercury is formed from inorganic mercury by the action of anaerobic organisms that live in aquatic systems including lakes, rivers, wetlands, sediments, soils and the open ocean.[6] This methylation process converts inorganic mercury to methylmercury in the natural environment."
But it can be human sourced
"Acute methylmercury poisoning occurred at Grassy Narrows in Ontario, Canada (see Ontario Minamata disease) as a result of mercury released from the mercury-cell Chloralkali process, which uses liquid mercury as an electrode in a process that entails electrolytic decomposition of brine, followed by mercury methylation in the aquatic environment."
this is typically associated with pulp and paper industry... there are a few located on the Athabasca River... interesting indeed

Step away from the thread and no one will get hurt.
