The major pollutants that cause acidic deposition are sulfur dioxide (SO2) and nitrogen oxides (NOx) produced during the combustion of fossil fuels. In the atmosphere these gases oxidize to sulfuric acid (H2SO4) and nitric acid (HNO3) that can be transported long distances before being returned to the earth dissolved in rain drops (wet deposition), deposited on the surfaces of plants as cloud droplets, or directly on plant surfaces (dry deposition). Electrical utilities contribute 70% of the 20 million tons (21 million metric tons) of SO2 that are annually added to the atmosphere. Most of...
