Ontario - is concerned about acid rain. The major source areas of acid rain are large industrial areas such as Ontario in Canada, and the Ohio River Valley area in the United States. (lNCO's Sudbury smelter is the world's largest single emitter of sulphur dioxide).
It is estimated that of all the acid rain pollutants being deposited in. Water quality is also an important concern for both human use of lakes and other freshwaters as well as the ecological value of water bodies. Water quality is used in determining the state of aquatic environments and is an interesting point of study in determining both human impacts and natural processes in the environment.
