EcoHumane Health People Phenomena ... Acid Rain Threatens Forests In More Ways Than Previously Thought Ban On Pollution Credit Swaps Voided Ruling deals a blow to state's efforts to reduce acid rain in Adirondacks by Dina Cappiello, April 10, 2002 A state law that penalized New York power plants for trading pollution credits to 14 other states was voided by a federal judge on Tuesday, removing a key part of the state's strategy to reduce acid rain in the Adirondacks. U.S. District Court Judge David N. Hurd in Utica ruled that the 2000 Air Pollution Mitigation Law was unconstitutional and conflicted with the federal Clean Air Act by restructuring the nationwide trading system whereby tons of sulfur dioxide emissions, or credits, are swapped freely between states.

Acid Rain: Do you need to start wearing a rainhat? 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. Causes of acid rain 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. Effects of acid rain The environment can generally adapt to a certain amount of acid rain. Often soil is slightly

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.

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
