Precipitation laced with pollution, produced predominantly by power plants that burn coal of variable purity, generating SO2 and NO2, lowering the pH of precipitation

acid rain

any rain that contains pollutants such as dissolved sulphur compounds, and as a result adversely affects plant and animal life on precipitation. The pollutants are released into the atmosphere by the burning of fossil fuels such as coal or oil.

(52) In advisory committee sessions, the Adirondack Council urged the EPA to adopt the approach taken in New York's Acid Deposition Act, and to retain the power to intervene in trades that might contribute additional deposition to sensitive resource areas.
Many other benefits are likewise ignored or underestimated in most studies, specifically the diminution of impacts and effects from improvements in stratospheric ozone depletion, acid deposition and hazardous air pollutants.
To understand the environmental impact of the CAAA and to develop new methods to protect the environment from acid deposition, it is important to address the relationship between emissions and deposition (the source-receptor relationship).(170) As a result, the National Acid Precipitation Assessment Program developed the Tagged Species Engineering Model ("TSEM") to analyze the source-receptor relationships.(171) By understanding the relationship between emissions and deposition, it is possible to identify the emissions source which produced particular acid deposition.
Besides learning about acid deposition, the participants also developed and perfected their skills in sampling and assessments of the results.
Over the past four decades, it became clear that the damaging effects of acid deposition on forests, agriculture, and soils needed to be documented.

Moreover, the assessment reports results of new supercomputer simulations using NAPAP's Regional Acid Deposition Model (RADM), indicating that cutting [SO.sub.2] emissions by 50 percent would not yield a commensurate decrease in acid deposition.

Years of research by Interior have shown that the problems associated with poor air quality--impaired visibility, acid deposition in streams, damage to plants from ozone, and eutrophication of coastal water--are increasing.
In 1980, President Carter created NAPAP as a 10-year program to study not only the causes and effects of acid deposition but also the best strategies for controlling iti(SN: 2/16/80, p.106).
