Acid Rain

The increase in the acidity of wet and dry depositions has been attributed to the increase of sulfate and nitrate and emissions from stationary and mobile sources.The problem of acid rain has reached dramatic proportions in many regions of the United States, Canada, Europe, and Japan. Monitoring of air and rain are essential to assess the effects of pollutants on global ecology. Ion chromatography (IC) offers the unique advantage of selective and rapid determination of low anion concentrations in acid rain.
