Acid Rain

"Acid Rain," or more precisely acidic precipitation, is the term used to describe rainfall that has a pH level of less than 5.6--a pH of 7 being neutral. This form of air pollution is currently a subject of great controversy because of the damage it does to the environment and property worldwide. For the last ten years, this occurrence has brought destruction to thousands of lakes and streams in the United States, Canada, and parts of Europe. It also leads to the deterioration of buildings and statues by reacting with several minerals. Acid rain is formed when oxides of nitrogen and sulfite combine with moisture in the atmosphere to make nitric and sulfuric acids. These acids can be carried away far from its origin. …show more content…

This gas attacks the membranes of the respiratory organs and increases the likelihood of respiratory illness. It also contributes to ozone damage, and forms smog (Phamornsuwana, http://www.geocities.com/CapeCanaveral/Hall/9111/DOC.HTML#SPECIFIC). Nitrogen oxide can spread far from the location it was originated by acid rain.

Changes in environment change the wildlife living in that environment. The lowering of pH from 7 to 4 is a dramatic change in environment, and the changes in wildlife reflect it. There are both direct and indirect effects of acid rain. Acid directly interferes with the ability of fish to take in oxygen, salt, and other nutrients needed to stay alive. Acidic conditions in the water cause mucus to form in the gills of fish, and prevents them from absorbing oxygen from the surrounding waters (Farnham, http://www.ems.psu.edu/info/explore/AcidRain.html). With a few exceptions adult fish are unable to survive in waters with a pH below 4.8. However, fish eggs and baby fish are unable to survive pHs below 5.5 (Farnham, http://www.ems.psu.edu/info/explore/AcidRain.html). If reproduction is not possible a given fish population will eventually die off even if the pH is not low enough to kill the adult fish. Most importantly, acid rain can harm us through the atmosphere or through the soil from which our food is grown. Acid rain causes toxic metals to break loose from their natural chemical compounds, thus making the
