Distilled wateronce carbon dioxide is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline.
A common example is nitric acid produced by electric discharge in the atmosphere such as lightning. History The corrosive effect of polluted, acidic city air on limestone and marble was noted in the 17th century by John Evelynwho remarked upon the poor condition of the Arundel marbles.
At first the main focus in research lay on local affects of acid rain. Public awareness of acid rain in the U.
S increased in the s after 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.
These areas all burn sulphur-containing coal to generate heat and electricity. The use of tall smokestacks to reduce local pollution has contributed to the spread of acid rain by releasing gases into regional atmospheric circulation.
An example of this effect is the low pH of rain which falls in Scandinavia. Ina group of scientists including Gene Likens discovered the rain that was deposited at White Mountains of New Hampshire was acidic.
The pH of the sample was measured to be 4. Acid rain that mixed with stream water at Hubbard Brook was neutralized by the alumina from soils. Experimental research was done to examine the effects of increased acidity in stream on ecological species.
There was a decrease in species diversity, an increase in community dominants, and a decrease in the food web complexity. Congress passed an Acid Deposition Act. 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. Government's 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.
Inthe panel of scientists came up with a draft report, which concluded that acid rain is a real problem and solutions should be sought. In Maythe House of Representatives voted against legislations that aimed to control sulphur 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 House's vote was due to the fact that the report was not ready to be published.
Subsequent Reports to Congress have documented chemical changes in soil and freshwater ecosystems, nitrogen saturation, decreases in amounts of nutrients in soil, episodic acidification, regional haze, and damage to historical monuments.
Meanwhile, inthe U. Congress passed a series of amendments to the Clean Air Act. It was implemented in two phases. Phase I began inand limited sulphur dioxide emissions from of the largest power plants to a combined total of 8.
Phase II began inand affects most of the power plants in the country.
During the s, research continued. This rule provides states with a solution to the problem of power plant pollution that drifts from one state to another. Inby which time the cap and trade system had been augmented by the George W.
A European Perspective' a first use of the term 'citizen science' by R. The first recorded example of the use of the term is fromdescribing how volunteers across the US collected rain samples to assist the Audubon Society in an acid-rain awareness raising campaign.
The volunteers collected samples, checked for acidity, and reported back to the organization. The information was then used to demonstrate the full extent of the phenomenon.
Emissions of nitrogen oxides which are oxidized to form nitric acid are of increasing importance due to stricter controls on emissions of sulphur containing compounds. Acid-producing gasses are also created by biological processes that occur on the land, in wetlandsand in the oceans.Glossary of Water Resource Terms.

This incredible phenomenon is . It's pretty clear how this phenomenon got its nickname: It looks like a tornado, but it's made of fire. "It's just like a spinning column of flames," forecaster Michael Watkins told the Los Angeles Times.
They form when wind patterns twist an active fire into a column. About once a year, the US sees one large fire whirl — as tall as feet.
