This section explains what acid rain is, where it comes from, and what its effects are. What causes acid deposition? Acid deposition - commonly called acid rain - is caused by emissions of sulphur dioxide and nitrogen oxides. Although natural sources of sulphur oxides and nitrogen oxides do exist, more than 90% of the sulphur and 95% of the nitrogen emissions occurring in eastern North America are of human origin. These primary air pollutants arise from the use of coal in the production of electricity, from base-metal smelting, and from fuel combustion in vehicles. Once released into the atmosphere, they can be converted chemically into such secondary pollutants as nitric acid and sulfuric acid, both of which dissolve easily in water. The resulting acidic water droplets can be carried long distances by prevailing winds, returning to Earth as acid rain, snow, or fog.

EPA's Clean Air Market Programs - Allowance Trading Basics U.S. Environmental Protection Agency's efforts to control air pollution concerns such as acid rain and groundlevel ozone through emission caps and market trading of emission allowances. http://www.epa.gov/airmarkets/trading/basics/index.html

Clean Air Markets - Allowance Trading Recent Additions Contact Us Print Version Search: EPA Home Clean Air Markets Allowance Trading Trading Basics ... Auctions Allowance Trading Basics Market-based mechanisms for reducing pollution include a variety of economic or market-oriented incentives and disincentives, such as tax credits, emissions fees, or tradeable emissions limitations (emissions trading for short). There are many types of emissions trading approaches; the one used by EPA's Clean Air Market Programs is called "allowance trading" or "cap and trade" and has the following key features: An emissions "cap" : a limit on the total amount of pollution that can be emitted (released) from all regulated sources (e.g., power plants); the cap is set lower than historical emissions to cause reductions in emissions Allowances : an allowance is an authorization to emit a fixed amount of a pollutant Measurement : accurate tracking of all emissions Flexibility : sources can choose how to reduce emissions, including whether to buy additional allowances from other sources that reduce emissions

31. What Is Acid Rain? [USGS] USGS logo What is acid rain? The term acid rain is commonly used to mean thedeposition of acidic components in rain, snow, fog, dew, or dry particles. http://pubs.usgs.gov/gip/acidrain/2.html

What is acid rain? 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.

ACID RAIN The Acid Rain WebQuest was featured in the March, 2001 episode of NetFiles View the episode by clicking HERE Introduction Why are the trees dying? How come there are no fish in the lake? Why does the paint on my Dad's car look so bad? Where does that terrible rotten egg smell come from in our school yard every Spring? 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, solving the acid rain problem is not. The Task A local citizens' group has hired you, and a group of other researchers, to investigate acid rain. You will take on the role of either a Chemist, Ecologist, Health Scientist, or Economist and examine the issue from that perspective. Working within this team, you will create a web site detailing the problems caused by acid rain and recommending ways that these problems can be alleviated. Within your group, decide who is going to assume the following roles. Use the questions appearing under each role to assist you in your research. While you are responsible for completing your section of the report, you will also be responsible for drawing up a series of recommendations, along with the other members of your team, on how to combat this serious issue.

USGS Tracks Acid Rain By John Gordon, Mark Nilles and LeRoy Schroder [Fact Sheet FS-183-95] WHAT IS ACID RAIN? Rain and snow are naturally slightly acidic due to chemical reactions with carbon dioxide in the atmosphere. The term "acid rain" is used to describe rain or snow that has a pH lower than what is natural for a given area. pH is a measurement of how acidic or basic a material is and ranges from to 14. Precipitation with a pH value less than 5 is considered acid rain. Graph depicting pH values for common substances. HOW DOES ACID RAIN FORM? Enormous quantities of manmade and natural material are added to the air every day. Overview of how acid rain forms. Because of global winds and mixing in the atmosphere, every country's air pollution contributes to some degree to the earth's problem of acid rain. In 1993, the United States released approximately 90 billion pounds of sulfur dioxide and nitrogen oxides into the air. Rain and snow that falls in the Eastern U.S. typically has a much lower pH than precipitation in other parts of the country. The pH of rain and snow in the Eastern U.S. is much lower than in less populated areas. Graph comparing pH readings for the Eastern U.S. with parts of the world with fewer coal burning powerplants and automobiles.
