What Is Acid Rain? [USGS]
The term acid rain is commonly used to mean the deposition of acidic components in When you hear or read in the media about the effects of acid rain,
http://pubs.usgs.gov/gip/acidrain/2.html

Extractions: The term "acid rain" is commonly used to mean the deposition of acidic components in rain, snow, fog, dew, or dry particles. The more accurate term is "acid precipitation." Distilled water, which contains no carbon dioxide, has a neutral pH of 7. Liquids with a pH less than 7 are acid, and those with a pH greater than 7 are alkaline (or basic). "Clean" or unpolluted rain has a slightly acidic pH of 5.6, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid. Around Washington, D.C., however, the average rain pH is between 4.2 and 4.4. The extra acidity in rain comes from the reaction of air pollutants, primarily sulfur oxides and nitrogen oxides, with water in the air to form strong acids (like sulfuric and nitric acid). The main sources of these pollutants are vehicles and industrial and power-generating plants. In Washington, the main local sources are cars, trucks, and buses. Wet and dry bucket collector, used to collect samples for measuring rainfall acidity. Acidity in rain is measured by collecting samples of rain and measuring its pH. To find the distribution of rain acidity, weather conditions are monitored and rain samples are collected at sites all over the country. The areas of greatest acidity (lowest pH values) are located in the Northeastern United States. This pattern of high acidity is caused by the large number of cities, the dense population, and the concentration of power and industrial plants in the Northeast. In addition, the prevailing wind direction brings storms and pollution to the Northeast from the Midwest, and dust from the soil and rocks in the Northeastern United States is less likely to neutralize acidity in the rain.
EPA - Air&Radiation
Deals with issues that affect the quality of our air. OAR develops national programs, technical policies, and regulations for air pollution control. Areas of concern to OAR include indoor and outdoor air quality, stationary and mobile sources of air pollution, radon, radiation protection, acid rain, stratospheric ozone depletion, and pollution prevention.

Extractions: [August 18, 2005] 2004 decreases in emissions of ozone forming nitrogen oxides (NOx) signal that ozone air quality throughout the eastern US is improving. According to a new report, "Evaluating Ozone Control Programs in the Eastern United States: Focus on the NOx Budget Trading Program, 2004", EPA's rule, known as the "NOx SIP Call,"has yielded reductions to improve air quality for more than 100 million people. [August 17, 2005] Fourteen communities across the United States are ahead of schedule in the effort to reduce ground-level ozone, or smog. Because of the progress these areas have made under EPA's Early Action Compacts program, the agency is taking final action to defer certain ozone pollution requirements until Dec. 31, 2006.

Extractions: Acid rain is a widespread term used to describe all forms of acid precipitation (rain, snow, hail, fog, etc.). Atmospheric pollutants, particularly oxides of sulphur and nitrogen, can cause precipitation to become more acidic when converted to sulphuric and nitric acids, hence the term acid rain. Acid deposition, acid rain and acid precipitation all relate to the chemistry of air pollution and moisture in the atmosphere. Scientists generally use the term acid deposition but all three terms relate to the same issue.

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.

Extractions: Go To The Document. Table Of Contence. Introduction. Information About Sulfur Dioxide. ... A Brief Summary About Acid Rain. "Acid Rain," or more precisely acid precipitation, is the word used to describe rainfall that has a pH level of less than 5.6. This form of air pollution is currently a subject of great controversy because of it's worldwide environmental damages. For the last ten years, this phenomenon has brought destruction to thousands of lakes and streams in the United States, Canada, and parts of Europe. 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. This report contains the causes, effects, and solutions to acid rain. The two primary sources of acid rain are sulfur dioxide (SO2), and oxides of nitrogen (NOx). Sulfur dioxide is a colourless, prudent gas released as a by-product of combusted fossil fuels containing sulfur. A variety of industrial processes, such as the production of iron and steel, utility factories, and crude oil processing produce this gas. In iron and steel production, the smelting of metal sulfate ore, produces pure metal. This causes the release of sulfur dioxide. Metals such as zinc, nickel, and copper are commonly obtained by this process. Sulfur dioxide can also be emitted into the atmosphere by natural disasters or means. This ten percent of all sulfur dioxide emission comes from volcanoes, sea spray, plankton, and rotting vegetation. Overall, 69.4 percent of sulfur dioxide is produced by industrial combustion. Only 3.7 percent is caused by transportation

Extractions: By 2007, 3.2 billion peoplea number larger than the entire global population of 1967will live in cities. Developing countries will absorb nearly all of the worlds population increases between today and 2030. The urban growth rate of 1.8 percent for 2000 to 2030 will double the number of city dwellers in less than 30 years. Meanwhile, rural populations are growing scarcely at all. In this cover story, E profiles some of the worlds largest and most environmentally challenged megacities. By Divya Abhat, Shauna Dineen, Tamsyn Jones, Jim Motavalli, Rebecca Sanborn, and Kate Slomkowski If our mega-cities coverage in this issue doesnt convince our readers and the substantial audience of international politicians and journalists also receiving it that the world has much bigger problems on its hands than terrorism, then I dont know what will. On September 11, 2001 some 3,000 people died in one single savage act in one day. Yet around the world 10 times that many children die in one day, every day.
