Extractions: Acid rain is one of the most dangerous and widespread forms of pollution. Sometimes called "the unseen plague," acid rain can go undetected in an area for years. Technically, acid rain is rain that has a larger amount of acid in it than what is normal. The acidity of rain in parts of Europe and North America has dramatically increased over the past few decades. It is now common in many places for rain to be ten to seventy times more acid than unpolluted rain. Many living and non-living systems become harmed and damaged as a result of acid rain. This website gives an informational, in-depth look at acid rainit's causes and effects; and solutions to the acid rain problem. Causes of Acid Rain Acid rain is caused by smoke and gases that are given off by factories and cars that run on fossil fuels. When these fuels are burned to produce energy, the sulfur that is present in the fuel combines with oxygen and becomes sulfur dioxide; some of the nitrogen in the air becomes nitrogen oxide. These pollutants go into the atmosphere, and become acid. Sulfur dioxide and nitrogen oxide are produced especially when coal is burnt for fuel. Burning coal produces electricity, and the more electricity that people use, the more coal is burnt. Of course, nowadays people probably couldn't live without electricity, so coal will continue to be burnt; but electricity and energy are constantly being

http://www.policyalmanac.org/environment/archive/acid_rain.shtml

Extractions: Wet deposition refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals. The strength of the effects depend on many factors, including how acidic the water is, the chemistry and buffering capacity of the soils involved, and the types of fish, trees, and other living things that rely on the water. Dry deposition refers to acidic gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition. The wind blows these acidic particles and gases onto buildings, cars, homes, and trees. Dry deposited gases and particles can also be washed from trees and other surfaces by rainstorms. When that happens, the runoff water adds those acids to the acid rain, making the combination more acidic than the falling rain alone. Prevailing winds blow the compounds that cause both wet and dry acid deposition across state and national borders, and sometimes over hundreds of miles. Scientists discovered, and have confirmed, that sulfur dioxide (SO2) and nitrogen oxides (NOx) are the primary causes of acid rain. In the US, About 2/3 of all SO2 and 1/4 of all NOx comes from electric power generation that relies on burning fossil fuels like coal.

http://www.ec.gc.ca/acidrain/acidfact.html

Extractions: What causes acid rain? Acid rain is rain, snow or fog that is polluted by acid in the atmosphere and damages the environment. Two common air pollutants acidify rain: sulphur dioxide (SO ) and nitrogen oxide (NO X ). When these substances are released into the atmosphere, they can be carried over long distances by prevailing winds before returning to earth as acidic rain, snow, fog or dust. When the environment cannot neutralize the acid being deposited, damage occurs. An acid is a substance with a sour taste that is characterized chemically by the ability to react with a base to form a salt. Acids turn blue litmus paper (also called pH paper) red. Strong acids can burn your skin. A pH scale is used to measure the amount of acid in a liquid-like water. Because acids release hydrogen ions, the acid content of a solution is based on the concentration of hydrogen ions and is expressed as "pH." This scale is used to measure the acidity of rain samples. The smaller the number on the pH scale, the more

EFFECTS OF ACID RAIN ON AQUATIC ECOSYSTEMS
Short primer, from University of Toronto.
http://www.scar.utoronto.ca/~weather/maryp/Effects/fish.html

Extractions: Henry David Thoreau The most dramatic reports of acid rain damages in the early 70s, were those of Ontario lakes having irreversible fish losses. Dead fish were washing up along the beaches, and the term "wet desert" was being used to describe the clear, blue, fishless lakes. Ontario now has over 100 fishless acidified lakes. Species such as lake trout (see top) , wall-eye, burbot and smallmouth bass have disappeared from most of these lakes. Starting in 1981, 202 lakes were monitored in Ontario, Quebec and the Atlantic Provinces, and in 1994, 33% showed some improvement in acidity while 11% were worse. The remaining 56% had stable acidity levels. Ontario lakes are especially sensitive to acid rain because of the hard bedrock of the Canadian Shield (an ancient sheet of Precambrian granite) and the poor soil cover which has poor buffering ability. It was first believed that the fish deaths were caused by the acids themselves, however, research has since shown that the high levels of aluminum (a toxic heavy metal) that were leached from the soil, was the real cause of the deaths. Aluminum can be acutely toxic to fish at pH levels that are not normally considered toxic to humans. A concentration as low as 6.2mg/L is known to kill fish.
