Acid RainA Contemporary World Problem 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

Acid Rain Web Quest A note for teachers Why are sugar maple trees are dying? Why are some frog species are becoming extinct? How come some lakes are crystal clear but there are no fish in it? Why does the paint on some cars look so bad? Why does the paint peel off bridges? The answer to these questions is simple; acid rain is responsible for many of the serious environmental problems facing us today. While the answer may be simple, understanding and solving the acid rain problem is not. Your task As a member of " Students for a Safer Environment ", your group has been invited to write a feature article for the environment section in your local newspaper, The Record The editor of the paper has heard great things about your group and how you have taken on environmental issues at school. He knows that acid rain has been on your agenda from talking to your teacher. He decided to give you the opportunity to tell the people in your community all about it. In your article you will cover 5 different aspects that will help people understand the Acid Rain problem. Each person in your group will cover one aspect. You are personally responsible for understanding and being able to explain the aspect you choose. Then, as a team, you will be responsible for drawing up

FastWeb Free Scholarship Search : Find free money for college or an advanced degree. var site="sm3pwl1776" Adapted from "Acid Rain", Environmental Protection Agency August 6th, 2002 What is Acid Rain and What Causes It? "Acid rain" is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. 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.

EFFECTS OF ACID RAIN ON AQUATIC ECOSYSTEMS A lake is the landscape's most beautiful and expressive feature. It is earth's eye: looking into which the beholder measures the depth of his own nature. 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.

What causes acid rain? Acid deposition is a general term that includes more than simply acid rain. Acid deposition primarily results from the transformation of sulphur dioxide (SO ) and nitrogen oxides into dry or moist secondary pollutants such as sulphuric acid (H SO ), ammonium nitrate (NH NO ) and nitric acid (HNO ). The transformation of SO and NOx to acidic particles and vapours occurs as these pollutants are transported in the atmosphere over distances of hundreds to thousands of kilometers. Acidic particles and vapours are deposited via two processes - wet and dry deposition. Wet deposition is acid rain, the process by which acids with a pH normally below 5.6 are removed from the atmosphere in rain, snow, sleet or hail. Dry deposition takes place when particles such as fly ash, sulphates, nitrates, and gases (such as SO and NOx), are deposited on, or absorbed onto, surfaces. The gases can then be converted into acids when they contact water. What does acid mean? 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.
