Mercury wafting out of oilsands operations is impacting an area – or “bull’s-eye” — that extends for about 19,000 square kilometres in northeast Alberta, according to federal scientists.
Levels of the potent neurotoxin found near the massive industrial operation have been found to be up to 16 times higher than “background” levels for the region, says Environment Canada researcher Jane Kirk, who recently reported the findings at an international toxicology conference.
Mercury can bioaccumulate in living creatures and chronic exposure can cause brain damage. It is such a concern that Environment Minister Leona Aglukkaq signed an international treaty in October pledging Canada to further reduce releases to the environment.
