Acidifying Pollutants, Arctic Haze, and Acidification in the Arctic
The emissions of acidifying compounds, sulfur dioxide (SO2) and nitrogen oxides (NOx), have increased since pre-industrial times as fuel combustion, population and industrial activity have increased worldwide. These pollutants occur in considerable quantities and cause adverse effects on human health and the natural environment. Sulfur emissions are mainly associated with point sources such as power plants, smelters, pulp and paper mills, and oil and gas processing. In contrast, nitrogen oxides are derived not only from power generating stations but also from diffuse emissions, which are less easy to quantify.
