"New Oilsands Testing Uncovers Higher Levels of Air Pollution"

"EDMONTON -- Warnings about higher levels of air pollution in the oilsands have emerged in a new provincial air quality report that calls for further investigation into possible pollution sources.

The report shows polluting emissions in 2012 did not surpass the legal limit set out in the Lower Athabasca Regional Plan. (Just two substances, sulphur dioxide and nitrogen dioxide, were measured). But air pollution rose to levels two and three on a scale of four at several monitoring sites, mostly between Fort McMurray and Fort McKay.

Level four is the legal limit set to protect human health and allow for economic growth."
