The environmental effects of acid deposition that have been most thoroughly studied are probably those on lakes, ponds, and other bodies of fresh water. When acid and oxides of sulfur and nitrogen are added to such bodies of water, the pH of the lake or pond tends... 

Some of the most dramatic environmental effects of acid deposition have involved buildings, statues, monuments, and other structures made of metal and stone. The explanation of this kind of damage is obvious Acids in acid deposition react with metals and with many of the compounds of which rock and other building material are made. For example, corrosion occurs when metals such as iron are exposed to hydrogen ions in the presence of oxygen ... 

The Cooperative program for monitoring and evaluation of long-range transmission of air pollutants in Europe (EMEP) was launched in 1977 as a response to the growing concern over the environmental effects of acid deposition. EMEP was organized under the auspices of the United...

Ultimately the mitigation to the environmental effects of acid deposition requires decrease in exposure through emission reduction. There has been considerable debate about how much and where reductions can be achieved from practical planning for SO and NO ... 

Marble and limestone surfaces were exposed to atmospheric conditions at four eastern U.S. sites and were monitored for changes in surface chemistry, surface roughness/re-cession, and weight. The effect of acid deposition, to which calcareous materials are especially sensitive, was of particular interest. Results are described for the first year of testing, and aspects of a preliminary equation to relate damage to environmental factors are discussed. Thus far, findings support that acid deposition substantially damages marble and limestone surfaces. 

It has to be bom in mind that in addition to well-recognized pollution mediated health effects, other major areas that have emerged in the 1990s in the domain of environmental pollution monitoring recently in India includes ozone layer depletion, greenhouse effect, persistence of chemical species, acidic deposition, and altered biogeochemical cycles. 

Acidic deposition alters soils, stresses forest vegetation, acidifies lakes and streams, and harms fish and other aquatic life. These effects can alter important ecosystem services such as forest productivity and water quality. Decades of acidic deposition have also made many ecosystems more sensitive to continuing pollution. Moreover, the same pollutants that cause acidic deposition contribute to a wide array of other important environmental issues at local, regional, and global scales (see Table 3.1).

The Parties further agree to consult on approaches to, and share information and results of research on, methods to mitigate the impacts of acidic deposition, including the environmental effects and economic aspects of such methods. 

Peter J. Dillon, Ph.D. (Toronto), F.R.S.C. is a Professor in the Environmental Resource Studies and Chemistry Departments at Trent University where he is Director of the new Water Quality Center. His research interests focus on biogeochemistry effects of regional and global-scale stressors including acid deposition, climate change, mercury and other trace metals on environmental chemistry.
