Acid Rain in Wisconsin
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 lo...
متن کاملAcid Rain
Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H+) concentration.] The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). As is seen in Table I, carbon dio...
متن کاملEnvironment Agency - Acid rain
Once the acidic gases have been emitted to the atmosphere they can be transported over large distances. Hydrogen chloride is highly soluble and is deposited close to source areas, whereas sulphur dioxide and nitrogen oxides are relatively insoluble (at atmospheric concentrations) and are therefore usually transported much further from the source before being deposited. For example, around 90% o...

متن کاملResponse of Soil Respiration to Acid Rain in Forests of Different Maturity in Southern China
The response of soil respiration to acid rain in forests, especially in forests of different maturity, is poorly understood in southern China despite the fact that acid rain has become a serious environmental threat in this region in recent years. Here, we investigated this issue in three subtropical forests of different maturity [i.e. a young pine forest (PF), a transitional mixed conifer and ...
