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.

Introduction Acidic pollutants can be deposited from the atmosphere to the Earth's surface in wet and dry forms. The common term to describe this process is acid deposition . The term acid precipitation is used to specifically describe wet forms of acid pollution that can be found in rain, sleet, snow, fog, and cloud vapor. An acid can be defined as any substance that when dissolved in water dissociates to yield corrosive hydrogen ions. The acidity of substances dissolved in water is commonly measured in terms of pH (defined as the negative logarithm of the concentration of hydrogen ions). According to this measurement scale solutions with pHs less than 7 are described as being acidic , while a pH greater than 7.0 is considered alkaline . Precipitation normally has a pH between 5.0 to 5.6 because of natural atmospheric reactions involving carbon dioxide. Precipitation is considered to be acidic when its pH falls below 5.6 (which is 25 times more acidic than pure water). Some sites in eastern North America have precipitation with pHs as low as 2.3 or about 1000 times more acidic than natural. Acid deposition is not a recent phenomena. In the 17th century, scientists noted the ill effects that industry and acidic pollution was having on vegetation and people. However, the term

26. Acid Rain acid rain Backgrounder. Purpose of this file To provide a primer on acid rainfor environmental journalists. acid rain harms more than aquatic life. http://www.lehigh.edu/~kaf3/books/reporting/acid.html

Acid Rain Backgrounder 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 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

31. 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

ACID RAIN 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 student shall be given opportunities to (B) observe properties and patterns of objects, organisms and events in the environment. (4) Communicate data and information in appropriate oral and written form. The student shall be given opportunities to (B) describe objects, organisms and events from the environment, (D) describe changes that occur to objects and organisms in the environment. Objective: Students will learn how acid rain is an air pollution problem. Focus: Show a picture of a defaced statue. Materials: chalk, vinegar and glasses for each group Background: Acid rain is more acidic than normal rain and forms through a complex process of chemical reactions involving air pollution. 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.

37. Acid Rain acid rain. Rain more acid than normal. So the problem of acid rain is reallyone of acid deposition in dry weather as well as wet. Nitrogen oxides. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/A/AcidRain.html

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). Sulfur dioxide 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 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 Types of damage 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).
