EFFECTS OF ACID RAIN ON TERRESTRIAL ECOSYSTEMS The thirsty earth soaks up the rain, And drinks, and gapes for drink again. The plants such in the earth and are With constant drinking fresh and fair. Abraham Cowley from Drinking Effects on Soil It was argued by early acid rain researchers that forests in Canada and northeastern U.S.A. are on acidic soils and therefore acid rain makes no difference to the forests. However, we now know this is not true. The effects of acid rain on soil is dependent on the behaviour of ions in the soil. Most of the ions of interest are cations such as Ca and Mg in addition to the cation H . These ions are the nutrients needed by plants. There are also toxic ions such as aluminum, lead, mercury, cadium and other metal ions. These ions are usually not free to migrate in the soil because they are bound to the negatively charged surface of immobile soil particles. These particles are negative because of the silicates on the surface of clays and the organic acids on particles of organic matter. The cation-exchange capacity is the ability of the soil to bind to the positively charged ions but acid rain depletes this capacity. Acid rain is able to mobilize these ions from the soil in two ways: The H+ ion in the acidic water displaces the other positive ions from their binding sites and increases the concentration of these ions in the soil water. When the soil particles are no longer able to bind anymore H+ ions, the concentration of H+ also increases in the soil water.

Acid Rain Written by Colin Hocking, Jacqueline Barber, and Jan Coonrod This stimulating unit fosters scientific inquiry and critical thinking skills as it harnesses the curiosity, agility, and determination of student minds to study the troubling environmental issue of acid rain. Students learn about acids, bases, and the pH scale; make "fake lakes" and determine how their pH changes after an acid rainstorm; present a play on the effects of acid rain on aquatic life; determine the effect of various dilutions of acid on seed germination; and hold a town meeting to discuss possible solutions to the problem of acid rain. A "startling statements" game challenges students' preconceptions and prompts investigation. In addition to providing much information on acid rain, the unit encourages students to analyze complex environmental issues for themselves, and emphasizes community cooperation (making it an effective companion unit to the GEMS guide Time: Eight or more 45- to 60-minute sessions.

68. ACID RAIN RETIREMENT FUND A R R F. Mission Statement. The acid rain Retirement Fund was foundedto prevent air pollution by buying it right out of the sky. http://www.usm.maine.edu/~pos/arrf.htm

A R R F Buying Pollution Right Out of the Sky! A R R F Mission Statement The Acid Rain Retirement Fund was founded to prevent air pollution by buying it right out of the sky. The U.S. Environmental Protection Agency issues pollution allowances or permits that enable companies to emit sulfur dioxide (SO2). These permits are auctioned off to the public and a permit for one ton of sulphur dioxide was recently about $130. The Acid Rain Retirement Fund raises funds and bids alongside polluters for as many pollution allowances as our funds can buy. We then retire that pollution credit permanently. As we buy pollution allowances we remove that amount of sulfur dioxide from our ecosystem forever. As we retire more pollution allowances, the price will go up. Polluting companies will need to bid larger amounts of money to continue polluting. As the price of polluting goes up, companies will be more inclined to invest money in technologies that remove pollution before it reaches the smokestack. The Acid Rain Retirement Fund is a nonprofit corporation that uses 100% of the money donated to buy pollution allowances. No portion of a donor's money will be use for administrative purposes unless the donor designates it so. We seek to bid on and remove as much pollution as possible from the environment.

All DiscoverySchool Students Teachers Parents DO Try This At Home! What is Acid Rain? Absolutely pure water is neutral - neither acid nor base. But rainwater is not absolutely pure. Some gases in the atmosphere dissolve in raindrops as they fall to the ground. Under normal conditions, rain is only slightly acidic. But chemical pollutants in the air - namely, sulfur and nitrogen - dissolve in rain to make it even more acidic. What causes acid rain? Acid rain is caused by two main pollutants in the air - sulfur dioxide and nitrogen dioxide. In the United States each year, more than 30 million tons of sulfur and nitrogen compounds are discharged into the air. But where are these dangerous gases coming from? Sulfur dioxide can come from natural sources, like volcanoes, but much of this gas is released into the atmosphere by factories that burn fossil fuels, such as coal and oil. Nitrogen dioxide comes from automobile exhaust and emissions from power stations.

Acid Rain Simulation Louie Beuschlein YES! I'd like to download the original onto Microsoft Word 6.0 or higher. Introduction : This is a two day unit plan that incorporates some decision-making ideas from statistics into the science classroom. It is intended for intermediate level science students (about high school freshman age) and beyond. No previous experience with statistical analysis is required. The NCTM Statistics Standard is taken into account in this lesson by having students make use of sampling to back up a claim and by having students design (with teacher assistance) a statistical experiment to study a problem. Acid Rain Lab : Acid rain is literally acid in rain water. It is a weak acid (sulfuric and nitric) but strong enough to damage buildings and statues and harm lakes, forests, and crops. The purpose of this lab is to investigate the damaging effects of acid rain on plants. In particular, students will determine whether and/or to what extent acid rain affects the germination rate of turnip seeds. The germination rates of seeds placed in an acid rain solution will be compared with that of the controlseeds placed in distilled water. Statistical methods will then be employed to determine whether any differences in germination rates is attributable to the acid rain or if it is reasonable to explain any differences as coincidences. The acid rain solution should be a mixture of dilute sulfuric and nitric acids (about pH 4). Students, working in groups of no more than four, should sandwich exactly 25 turnip seeds (or some other type of seed) between two layers of paper toweling saturated in acid rain solution. (There should be no pools of solution.) Each group should also prepare a control Petri dish in which distilled water is used in place of the acid rain solution. The Petri dishes should then be wrapped in aluminum foil to keep them in darkness and allowed to remain undisturbed (preferably for a weekend).

Acid Rain 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.

UK Acid Rain In the 1980s, the UK was described by Scandinavian countries as ‘the dirty old man of Europe’ due to high emissions of sulphur dioxide from industrial sources causing transboundary acid rain. Emissions of sulphur dioxide and oxides of nitrogen have since been reduced, although the UK remains a considerable emitter of acidic pollution compared to other European countries. Most of the UK sulphur dioxide comes from power stations (65% in 1999) and other industries (22% in 1999) whilst the largest source of nitrogen oxides is road transport (44% in 1999) and power stations (21% in 1999). Total deposition of sulphur on the UK during 1998 was around 0.33 million tonnes compared to 1.19 million tonnes emitted in 1999. This highlights that the UK emits more sulphur pollution than is deposited in the UK. A significant proportion of sulphur and nitrogen pollutants are exported to other countries, mainly Germany, France, Norway, Sweden, the Netherlands and Russia. The wind direction is the main factor affecting where UK pollutants are deposited. The UK experiences typical impacts from acid rain. In 1995, the United Nations Economic Commission for Europe (UNECE) Forest Survey revealed that 42% of UK

Sulfur Dioxide Big Trucks: The Dirty Truth Survey Results Control Technologies The Clean Air Act: Basic Objectives Restated The Clean Air Act: Recommended Reading Site Search Links to Other Resources Contact Us Acid rain (or acid deposition, as it's called in technical circles) is produced by the burning of fossil fuels. It is formed when emissions of sulfur dioxide and nitrogen oxides react in the atmosphere with water, oxygen and oxidants to form various acidic compounds. These compounds then fall to the ground in either wet or dry form. Acid rain acidifies lakes and streams and contributes to damage of trees at high elevations. (Check out Mount Mitchell in North Carolina if you want a graphic example of tree damage.) Hundreds of lakes in the Adirondacks have become too acidic to support sensitive fish species. In addition, acid rain accelerates the decay of paints and buildings. Electric power plants account for about 70 percent of sulfur dioxide emissions about 30 percent of nitrogen oxides emissions. Cars, trucks and buses also are major sources of nitrogen oxides.

78. Acid Rain pollution. HOW acid rain IS FORMED. acid rain is caused by the releaseof the gases SO2 (sulphur dioxide) and NOX (nitrous oxides). The http://www.botany.uwc.ac.za/Envfacts/facts/acidrain.htm

WHAT ARE ACIDS? There are many different kinds of acids. The proteins in our food, and in our bodies, are made up of amino acids. Motor cars start because of the sulphuric acid in their batteries. Swimming pools need hydrochloric acid, commonly known as `pool acid'. Some acids are weak, e.g acetic acid (vinegar) and lemon juice. They are not harmful and are used in preparing our food. Othershowever, such as sulphuric acid (battery acid) are strong and can burn holes in our clothes. WHAT SHOULD RAIN BE LIKE? The only place on earth where pure water is found is in a laboratory. Rain water always contains small amounts of impurities. These impurities come from dust particles or are absorbed from the gases in the air. If pure water is exposed to the air it absorbs carbon dioxide to form carbonic acid and becomes slightly acidic, dropping from pH 7 i.e. neutral, to pH 5,6. Even in remote, unpopulated areas rain can reach a pH of 4,5. However, a pH of less than 4,5 in rain is almost certainly caused by pollution. HOW ACID RAIN IS FORMED Acid rain is caused by the release of the gases SO2 (sulphur dioxide) and NOX (nitrous oxides). The main sources of SO2 in South Africa are coal-fired power stations and metal working industries. The main sources of NOX emissions are vehicles and fuel combustion.

Acid Rain in Wisconsin This information originally appeared in the DNR booklet "Acid Rain in Wisconsin," publication AM-129-94. What is acid rain? And where does it come from? How do we measure acidity? What do we know about the effects of acid rain in Wisconsin? What legislative action has been taken? ... Contacts The effects of acid rain are evident in New York's Adirondack Mountains, in Germany's Black Forest, and industrial urban areas around the worldand the picture is not a pretty one. It includes stands of dying trees, lakes uninhabitable by fish, and weathered and damaged historic architecture. While acid rain has not caused such severe problems in Wisconsin as in the places mentioned above, it is still an air pollution issue that generates concern among the state's residents. Frequently asked questions are: How bad is the problem in the state? What are the causes? What is being done to protect Wisconsin's resources? What is acid rain? And where does it come from? While pure rain is naturally slightly acidic, the higher level of acidity in acid rain makes it a threat to plant and aquatic life and to some manmade materials and structures. The slight natural acidity of pure rain is the result of carbon dioxide in the air dissolving in water to produce a weak carbonic acid solution. This natural acid in rainfall and snowmelt is partly responsible for the long, slow weathering of soil and rocks. Acid rain, however, is the result of sulfur dioxide and nitrogen oxides entering the atmosphere. These two pollutants are mainly produced by human activities. Sulfur dioxide is most commonly produced by coal-fired power plants and factories, while nitrogen oxides are products of motor vehicles and off-road engines, coal-fired power plants and factories (such as pulp and paper mills in Wisconsin), and home furnaces.
