Acid rain is very harmful to everything over a period of time. There are many forms of acid rain that are seen around the world. In wet weather there is acid rain, acid snow, and acid fog. In dry weather there is acid gas and acid dust. Acid rain is formed by pollution, which is released into the air. ... The damage of acid rain causes worldwide environmental problems. ... These chemicals react with water and other chemicals in the air to form sulfuric acid, nitric acid, and other pollutants. These acid pollutants reach high into the atmosphere, travel with the wind for hundreds of miles, and eventually return to the ground by way of rain, snow, or fog, and as invisible “dry” forms. Damage from acid rain has been widespread in eastern North America throughout Europe, Japan, China, and Southeast Asia (Hart, John B. ... Acid rain takes nutrients and vital sources from soil, slows the growth of trees, and makes lakes unlivable for aquatic life. In cities, acid pollutants erode almost everything they touch, such as buildings and statues. ... Rain becomes acidic because of the gases, which dissolve in the rainwater to form various acids. Major contributing gases for acid rain are sulfur dioxide (SO2), oxides of nitrogen (NOx), carbon dioxide (CO2) and chlorine (CI2). The following reactions show the acid formation due to these gases (Cherrington, Brett; 1996): Sulfur dioxide reacts with water to form sulfuric acid (SO42-). Oxides of nitrogen react with water to form nitric acid (NO3-). Carbon dioxide (CO2) reacts with water to form carbonic acid (HCO3-). Chlorine (CI2) reacts with water to form Hydrochloric acid (CI-). ... Automobiles release harmful smoke into the air, which causes acid rain. ... Acid rain effects almost everything and anything over a period of time. ... On sea life, acid rain damages all the plants and animals living inside a body of water. Acid rain causes lakes and rivers to become acidic, killing off fish. ... Short-term increases in acid levels kill lots of fish, but the greatest threat is from long-term increases, which stop the fish from reproducing. |
