Atmospheric Issues
Atmospheric issues occur when a form of pollution interferes with the natural balance of the major gases and compromise the atmosphere having a variety of effects. These forms of pollution can be confused with indoor air pollution. Indoor air pollution is something that contaminates the air inside a building. Carbon monoxide, cleaning products, bacteria, and nitrogen dioxide are just a few examples or indoor air pollution. A few examples of atmospheric pollutants would be methane, dust, ozone, and microorganisms. Acid rain can be a result of atmospheric pollution.
Acid Rain is a combination of both wet and dry deposition that comes from the atmosphere that contains a higher than normal amount of sulfuric and nitric acids. The precursors of acid rain come from man-made sources, like emissions of nitrogen oxides and sulfur dioxide from the combustion of fossil fuels, and natural sources, like decaying vegetation and volcanoes (United States Environmental Protection Agency, 2012.) In America approximately 2/3 of the pollution that comes from the burning of fossil fuels are released into the air from the electric power that our generation relies so much on. When these gases mix with the gases that are already in the atmosphere, oxygen, water, and other chemicals multiple forms of acidic compounds are created and that results in a mild form of nitric acid and sulfuric acid (United States Environmental Protection Agency, 2012.)
Fog, snow, and acid rain are referred to as wet deposition. This occurs if the acid chemicals or compounds are blown into an area where the weather is wet causing the acids to come down in fog, mist, snow, or rain. This acidic water has direct effects on many different animals and plants as it travels over the ground. Dry deposition occurs in places where the weather is dry. The acidic chemicals mix with smoke or dust and end up on the ground generally sticking...
