Extractions: Acid rain refers to all types of precipitationrain, snow, sleet, hail, fogthat is acidic in nature. Acidic means that these forms of water have a pH lower than the 5.6 average of rainwater. Acid rain kills aquatic life, trees, crops and other vegetation, damages buildings and monuments, corrodes copper and lead piping, damages such man-made things as automobiles, reduces soil fertility and can cause toxic metals to leach into underground drinking water sources. Rain is naturally acidic because carbon dioxide, found normally in the earth's atmosphere, reacts with water to form carbonic acid. While "pure" rain's acidity is pH 5.6-5.7, actual pH readings vary from place to place depending upon the type and amount of other gases present in the air, such as sulphur oxide and nitrogen oxides. The term pH refers to the free hydrogen ions (electrically charged atoms) in water and is measured on a scale from to 14. Seven is considered neutral and measurements below seven are acidic while those above it are basic or alkaline. Every point on the pH scale represents a tenfold increase over the previous number. Thus, pH 4 is 10 times more acidic than pH 5 and 100 times more so than pH 6. Similarly, pH 9 is 1O times more basic than pH 8 and 100 times more basic than pH 7. The acid in acid rain comes from two kinds of air pollutants sulphur dioxide (SO2) and nitrogen oxides (NOx). These are emitted primarily from utility and smelter "smokestacks" and automobile, truck and bus exhausts, but they also come from burning wood.

Rivers

http://www.wildlifetrust.org.uk/facts/rivers.htm

Extractions: Rivers and the surrounding land drained by them (catchments) are very important wildlife habitats. The water itself provides the environment for fish, plants and animals, while the banks and nearby land support creatures such as otters, kingfishers and dragonflies and a variety of water-loving plants. Between 1985 and 1990 there was a decrease in the total length of rivers and canals in England and Wales having top quality water. Meanwhile the total length of 'poor' quality waterways increased. Since 1990 the situation in England and Wales has improved. The Environment Agency reports an increase in length in the best quality grades of waterway and a reduction in the poorest. Indeed there has been significant improvement in 10.7% of the total length of rivers and canals in England and Wales. Where does pollution come from? There are several sources of water pollution which work together to reduce overall river water quality. Industry and agriculture discharge liquid waste products. Rain as it falls through the air, or drains from urban areas and farmland, absorbs contaminants. Serious incidents resulting from spillages or discharges of toxic chemicals are the pollution events that make the news. For example, just one litre of insecticide killed over 1,000 fish in the River Glaven in Norfolk. The impact of a slow build-up of pollution over a long time and in a wide area can be even more serious. During the 1950s, otters in many parts of the country were nearly wiped out by the accumulation of pesticides in our rivers
ENERGY FACTS: ACID RAIN
acid rain. acid rain Chemistry. As mentioned earlier, the term acid rainis used to describe a variety of different types of acidic deposition.
http://www.iclei.org/efacts/acidrain.htm

Extractions: Acid rain is a term which is used to describe a variety of processes which might more accurately be referred to as acidic deposition. Natural rainfall is slightly acidic due to dissolved carbon dioxide, picked up in the atmosphere. Organisms and ecosystems all over the planet have adapted to the slightly acidic nature of normal rain, and thus it poses no environmental problems. It is an increase in the acidity of rain, caused by human activities such as the combustion of fossil fuels, that has turned acid rain into a problem. Highly acidic rain can damage or destroy aquatic life, forests, crops and buildings, as well as posing a threat to human health. The actual term "acid rain" was first used over one hundred years ago by British chemist Robert Angus Smith. At that time, he realized that smoke and fumes from human activities could change the acidity of precipitation. Despite this awareness, acid rain was not considered an environmental concern until the 1950's. Around this time, increased levels of acidity were discovered in lakes in both Canada and Scandinavia. At first, this was looked at as simply an interesting situation, rather than a problem. Since that time, much research has gone into identifying the sources of acid rain and the damage that it causes. As research continued, the situation reached crisis proportions in the late 1970's. By this time, thousands of lakes in Canada and Scandinavia had been declared dead, devoid of life, while emissions of acid gasses continued to increase.

The two most important pollutants that contribute to the formation of acid rain are oxides of nitrogen and sulfur dioxide, which react with moisture in the atmosphere to form nitric and sulfuric acid. The sulfur and nitrogen compounds that contribute to acid rain primarily come from manmade sources, such as industries and utilities. Emissions also come from automobiles and other forms of transportation and industrial processes, such as smelting. Acid rain can harm forests and crops, damage bodies of water, and contribute to the damage of statues and buildings. Researchers are considering the possible effects of acid rain on human heath. These acidic pollutants can be deposited through rain, snow, fog, dew, or sleet. Large quantities can also be deposited in a dry form through dust.

Pollutants that contribute to acid rain may be carried hundreds of miles before being deposited on the earth. Because of this, it is sometimes difficult to determine the specific sources of these acid rain pollutants.

http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/A/AcidRain.html

Extractions: Acid Rain Rain more acid than normal. Natural rain and snow is slightly acidic ( pH 5.6) because of the carbon dioxide dissolved in it. But over recent decades, rain in North America and Europe downwind of industrial areas has had a pH close to 4.5 and sometimes as low as 2.1 (equivalent to lemon juice). The evidence is very strong that most of this acidity is caused by sulfur dioxide released from the smokestacks of coal-burning power plants and other industrial sources. The sulfur dioxide is converted into sulfuric acid. This may be carried to the ground in rain or snow, but often particles containing sulfuric acid settle out of dry air. So the problem of acid rain is really one of acid deposition in dry weather as well as wet. Nitrogen oxides ("NO x "), which are converted into nitric acid, also contribute to acid deposition. Automobile exhaust accounts for 50% or more of the nitrogen oxides in polluted air. View Acid rain has been held responsible for damaging buildings and statues made of limestone (true - view an example ), damaging aquatic life in lakes (true), causing a decline in the vigor of U.S. and European forests (may be partially responsible), and harming human health (doubtful).

http://ga.water.usgs.gov/edu/acidrain.html

Extractions: Depending on where you live, maybe you've heard of acid rain. Now, acid rain is not pure acid falling from the sky, but rather it is rainfall or atmospheric moisture that has been mixed with elements and gases that have caused the moisture to become more acidic than normal. Pure water has a pH of 7, and, generally, rainfall is somewhat on the acidic side. But, acid rain can have a pH of about 5.0-5.5, and can even be in the 4 range in the northeastern United States, where there are a lot of industries and cars. Acid rain is a uniquely human-related phenomenon. The burning of fossil fuels (coal and oil) by power-production companies and industries releases sulfur into the air that combines with oxygen to form sulfur dioxide (SO ). Exhausts from cars cause the formation of nitrogen oxides in the air. From these gases, airborne sulfuric acid (H SO ) and nitric acid (HNO ) can be formed and be dissolved in the water vapor in the air. Although acid-rain gases may originate in urban areas, it is often carried for hundreds of miles in the atmosphere by winds into rural areas. That is why forests and lakes in the countryside can be harmed by acid rain that originates in cities. The environment can generally adapt to a certain amount of acid rain. Often soil is slightly
