Current status of acid deposition science in Canada

Environment Canada has released the 2004 Canadian Acid Deposition Science Assessment which shows that despite Canada's success at reducing acid causing emissions, acid deposition is still affecting our environment.

Scientific research in 2004 and Canada, acid rain, and the collection in Canada and the impact of acid in the evaluation of technical surveillance. Universities and federal and state levels, acid about the current state of knowledge is evaluated by experts.

Despite the spread of wrong ideas, according to new research the problem of acid rain, does, and solution to this problem. Eastern Canada and the important parts of the load between 75 to 21% of the acids (volume) can not be affected by acid rain continues to receive. Canada for the stability of ecosystems is the potential for acid.

Is estimated that in Canada, Canada, the United States of America in 2010 by the conservation of these ecosystems in terms of, in Canada, air quality, SO2 emissions, the U.S. decision to further reduce the acid in 75 per cent, including the loss against the . At this time, the right, but in Europe, the scope of the assessment of ecosystem acid can.

Canada and the U.S., the major emission sources in addition to inorganic acid, base metals, mining, fusion, electricity, oil and gas activities, production, transport and processing of oil.

Acidic lakes, rivers, soil, forests, vegetation and fauna, biodiversity and human health and harm the plants. For example, 50 per cent of the boreal forest to live a healthy and meaningful future is angry. There is evidence to suggest that acid rain is currently reducing the growth rate of trees in eastern Canada; it has been estimated that over half a million cubic meters of wood, at a value of hundreds of millions of dollars, is being lost from forests each year. Rivers and lakes of acid, or acid-sensitive areas in the eastern Netherlands in the back in its place and aquatic organisms are sensitive to fish, where to support. Decrease in fish, affecting sports fishing.

However, there are signs of improvement are promising. East Canada Lake, close to a merger for the recovery of evidence and, ultimately, the increase in lake pH (Sudbury, Rouyn - Noranda) measured by the reduction in emissions. Southern Canada, the first symptoms of acid and acid emission reduction due to the lack of carbon in the lakes on the basis of the acid.

That climate change and smog, including the acid is associated with many other environmental issues.

The acid solution of the problem is not clear yet.
