Acid rain Wikipedia. Processes involved in acid deposition note that only SO2 and NOx play a significant role in acid rain. Acid clouds can grow on SO2 emissions from refineries, as seen here in Curaao. Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions low p. H. It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts since the 1. Nitrogen oxides can also be produced naturally by lightning strikes, and sulfur dioxide is produced by volcanic eruptions. Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health. DefinitionAcid rain is a popular term referring to the deposition of a mixture from wet rain, snow, sleet, fog, cloudwater, and dew and dry acidifying particles and gases acidic components.

H of 7. Liquids with a p. H less than 7 are acidic, and those with a p. H greater than 7 are alkaline. Clean or unpolluted rain has an acidic p. H, but usually no lower than 5. H2. O l CO2 g H2.

A common example is nitric acid produced by electric discharge in the atmosphere such as lightning. Acid deposition as an environmental issue discussed later in the article would include additional acids other than H2. CO3. History. The corrosive effect of polluted, acidic city air on limestone and marble was noted in the 1. John Evelyn, who remarked upon the poor condition of the Arundel marbles. Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides into the atmosphere have increased. In 1. Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England. Though acidic rain was discovered in 1. The term acid rain was coined in 1. Robert Angus Smith. Canadian Harold Harvey was among the first to research a dead lake. Public awareness of acid rain in the U. S increased in the 1. The New York Times published reports from the Hubbard Brook Experimental Forest in New Hampshire of the myriad deleterious environmental effects shown to result from it. Occasional p.

These areas all burn sulfur containing coal to generate heat and electricity. The problem of acid rain has not only increased with population and industrial growth, but has become more widespread. The use of tall smokestacks to reduce local pollution has contributed to the spread of acid rain by releasing gases into regional atmospheric circulation. Often deposition occurs a considerable distance downwind of the emissions, with mountainous regions tending to receive the greatest deposition simply because of their higher rainfall. An example of this effect is the low p. H of rain which falls in Scandinavia. In the United States. Creative X-Fi Elite Pro Drivers Windows 7 64 Bit. Since 1. 99. 8, Harvard University wraps some of the bronze and marble statues on its campus, such as this Chinese stele, with waterproof covers every winter, in order to protect them from corrosion caused by acid rain and acid snow1. The earliest report about acid rain in the United States was from the chemical evidence from Hubbard Brook Valley. In 1. 97. 2, a group of scientists including Gene Likens discovered the rain that was deposited at White Mountains of New Hampshire was acidic. The p. H of the sample was measured to be 4. Hubbard Brook. 1. The Hubbard Brook Ecosystem Study followed up with a series of research that analyzed the environmental effects of acid rain. Acid rain that mixed with stream water at Hubbard Brook was neutralized by the alumina from soils. The result of this research indicates the chemical reaction between acid rain and aluminum leads to increasing rate of soil weathering. Experimental research was done to examine the effects of increased acidity in stream on ecological species. In 1. 98. 0, a group of scientists modified the acidity of Norris Brook, New Hampshire, and observed the change in species behaviors. There was a decrease in species diversity, an increase in community dominants, and a decrease in the food web complexity. In 1. 98. 0, the U. S. Congress passed an Acid Deposition Act. This Act established an 1. National Acidic Precipitation Assessment Program NAPAP. NAPAP looked at the entire problem from a scientific perspective. It enlarged a network of monitoring sites to determine how acidic the precipitation actually was, and to determine long term trends, and established a network for dry deposition. It looked at the effects of acid rain and funded research on the effects of acid precipitation on freshwater and terrestrial ecosystems, historical buildings, monuments, and building materials. It also funded extensive studies on atmospheric processes and potential control programs. From the start, policy advocates from all sides attempted to influence NAPAP activities to support their particular policy advocacy efforts, or to disparage those of their opponents. For the U. S. Governments scientific enterprise, a significant impact of NAPAP were lessons learned in the assessment process and in environmental research management to a relatively large group of scientists, program managers and the public. In 1. 98. 1, the National Academy of Sciences was looking into research about the controversial issues regarding acid rain. President Ronald Reagan did not place a huge attention on the issues of acid rain2. Canada and confirmed that Canadian border suffered from the drifting pollution from smokestacks in Midwest of US. Reagan honored the agreement to Canadian Prime Minister. Pierre Trudeaus enforcement of anti pollution regulation. In 1. 98. 2, US President Ronald Reagan commissioned William Nierenberg to sit on National Science Board. Nierenberg selected scientists including Gene Likens to sit on a panel to draft a report on acid rain. In 1. 98. 3, the panel of scientists came up with a draft report, which concluded that acid rain is a real problem and solutions should be sought. White House Office of Science and Technology Policy reviewed the draft report and sent Fred Singers suggestions of the report, which cast doubt on the cause of acid rain. The panelists revealed rejections against Singers positions and submitted the report to Nirenberg in April. In May 1. 98. 3, the House of Representatives voted against legislations that aimed to control sulfur emissions. There was a debate about whether Nierenberg delayed to release the report. Nierenberg himself denied the saying about his suppression of the report and explained that the withheld of the report after the Houses vote was due to the fact that the report was not ready to be published.
