Abstract
Acid rain refers to all types of precipitation- rain, snow, sleet, hail, fog- that is acidic in nature. The recent rapid acidification of many lakes including Lake Atawapaskat can not be attributed to natural causes alone, but instead to the effects of acidic pollution from the burning fossil fuels by mankind. The acidity of this lake is predominantly determined by the soil and rock type of this area because 90% of the water entering this lake comes from ground water and streams. Only 10% of the water that enter this lake comes directly from rainfall. Lake Atawapaskat is more susceptible to freshwater acidification due to its acidic geology such as granite and peat-based soil. Recently acid rain has been entering more than usual through the catchment. Some of the acid rain has been neutralized due to its alkaline-rich soil, so the water entering the lake is of low acidity. (K.M.,Oghenejoboh; 2005) Acidification of the lake occurred with time. The first natural buffering......
