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?

Though it will never be complete, it provides all the online resources for individuals to monitor and help our environment. Acid Rain "Acid rain" is a general name for many phenomena including acid fog, acid sleet, and acid snow. Although we associate the acid threat with rainy days, acid deposition occurs all the time, even on sunny days. Something is acidic if it has a low pH. The pH of a liquid is measured on a scale which ranges from to 14 with 7.0 being neutral. Anything with a pH value lower than 7.0 is acidic, and anything higher than 7.0 is basic. Particles of sulphur and nitrogen emitted by cars, coal-fired generators, and non-ferrous smelters can be carried great distances and deposited anywhere from a few hundred to a few thousand kilometers from their source area. Even when sulphur and nitrogen particles fall to the surface as dry deposition they combine with water at the earth's surface or in the ground to produce the same effects as wet deposition. Acid rain has become a grave problem. North America and Europe are the areas with the most problematic and noticeable overall acid precipitation levels. They both receive precipitation with pH as low as 4.7. Acid deposition endangers forests, lakes and agriculture. No single storm or event can cause all this remarkable damage. Rather, the effects of acid rain occur as a slow and continuous process.

Extractions: Every day of the year, industry and motor vehicles spew out gases, which when hit by the sunlight, change into acids. The acids collect on clouds and when it rains, come straight down onto us. Marble is a common building material, and what we have here is marble chips. I'm going to add some acidity here. About 10 times more acid than the most acid rain. But you can see immediately that the acid attacks the marble and starts to dissolve it. It's not what you'd want in your cup of coffee, so Dr.Greg Ayers from Australia's science agency, CSIRO, is collecting samples of rain and measuring them for acidity. Ph is measured from Zero to fourteen. On the alkaline side, seawater is around 8 and at the acidic end Orange juice and soft drinks are around PH2 or 3. Unpolluted rainwater should measure at around PH 5 and any measurement under 5 would be considered Acid Rain. As Australia is sparsely populated, its cities are far apart and it has no neighbors, the readings are not very high. In areas where there are smelters and power stations however, the problem of acid rain is far greater. The major effects are on forests and rivers and lakes, where the acid rain causes the soil or water to be so acidified that trees won't grow or in fact they can even die completely and rivers and lakes they can become so acidic that they won't support any sort of aquatic life.

Extractions: What is Acid Rain? Acid rain is a result of air pollution. When any type of fuel is burnt, lots of different chemicals are produced. The smoke that comes from a fire or the fumes that come out of a car exhaust don't just contain the sooty grey particles that you can see - they also contains lots of invisible gases that can be even more harmful to our environment. Power stations, factories and cars all burn fuels and therefore they all produce polluting gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain".

The fight against acid rain is not over yet. Acid deposition exceeds critical loads across large portions of eastern Canada, including most of New Brunswick and Nova Scotia. As a result, acidification in these areas will continue, the biodiversity of aquatic ecosystems will remain under threat, and more damage to forest health and productivity will occur unless further deep cuts in sulphur dioxide and nitrogen oxide emissions in Canada and the United States are implemented.

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.

http://www.citizenscampaign.org/campaigns/acid_rain.htm

Extractions: CAMPAIGNS Acid Rain CCE has been working to fight the devastating impacts of acid rain in New York and Connecticut since 1997. Acid rain is created when fossil fuels are burned, primarily in electric power plants and automobiles, producing sulfur dioxide and nitrogen oxides. These air pollutants react with water vapor in clouds, oxygen and oxidants in air, forming sulfuric acid and nitric acid. The acids fall to earth in wet form, either as rain, snow or fog, or dry form, as gas or solid particles The Mechanics of Acid Rain Art by Rani Stack Photo by Gary A. Randorf CCE advocates a national approach to solving the acid rain problem that is based on reducing the emissions of sulfur and nitrogen from major sources such as electric power plants. In 1997, at the urging of CCE members and citizens throughout New York, acid rain legislation was introduced into the United States Congress by Senator Daniel Patrick Moynihan. The Moynihan legislation focused on cutting power plant emissions of nitrogen oxides by 70% and sulfur dioxides by 50% from existing levels under the Federal Clean Air Act. Scientific monitoring and research has determined that these levels of emission reduction would halt and reverse the damage of acid rain, particularly in high elevation areas such as the Adirondack Mountains.

As is seen in Table I, carbon dioxide (CO ) is present in the greatest concentration and therefore contributes the most to the natural acidity of rainwater. Carbon dioxide

http://news.nationalgeographic.com/news/2002/08/0813_020813_acidrain.html

Extractions: August 13, 2002 Acid rain may be forgotten, but it is not gone, and now researchers at the Cornell Laboratory of Ornithology have linked it to the decline of the wood thrush, a forest bird known for its beautiful song. Using data from the BBS, from government studies of acid rain and soil acidity, and from a Cornell Lab study of forest fragmentation, the researchers did a statistical analysis and found that increased amounts of acid rain make wood thrushes less likely to breed. An article on the finding appears in the August 12 issue of Proceedings of the National Academy of Sciences. "I was surprised that we uncovered a negative effect this big," said Stefan Hames, an ecologist and ornithologist at Cornell, and one of the article's five coauthors. "Like many people, I thought acid rain was a non-issue." In the United States, the Clean Air Act has brought about a reduction in the emissions that cause acid rain, but as Hames and his colleagues point out, "many eastern regions of North America continue to experience heavy, wet acidic deposition, and many bird species breeding in these areas show unexplained population declines. Further, long-term acid deposition has depleted the available calcium in acid-sensitive soils, and current emission standards may be insufficient to ensure the recovery of these soils."
