Acid deposition also occurs via dry deposition in the absence of precipitation. This can be responsible for as much as 20 to 60% of total acid deposition. [ 69 ] This occurs when particles and gases stick to the ground, plants or other surfaces.
In United States federal environmental legislation, the National Acid Precipitation Assessment Program (NAPAP) was authorized by Congress under the Acid Precipitation Act of 1980 (P.L. 96-294, Title VII) because of concern that acidic deposition might contribute to adverse effects on aquatic systems; agriculture; forests; fish; wildlife and natural ecosystems; materials such as metals, wood ...
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

The Acid Rain Retirement Fund (A.R.R.F) is an all-volunteer, non-profit environmental educational organization, incorporated in Maine, dedicated to reducing pollution by purchasing and "retiring" marketable sulfur dioxide emissions allowances issued by the U.S. Environmental Protection Agency’s Acid Rain Program. A.R.R.F. was created in 1995 ...
The National Atmospheric Deposition Program (NADP) is a Cooperative Research Support Program of the State Agricultural Experiment Stations (NRSP-3). Housed at the Wisconsin State Laboratory of Hygiene at the University of Wisconsin–Madison, [1] the NADP is a collaborative effort between many different groups, such as: Federal, state, tribal, local governmental agencies, educational ...
Ocean alkalinity enhancement (OAE) is a proposed "carbon dioxide removal (CDR) method that involves deposition of alkaline minerals or their dissociation products at the ocean surface". [34]: 2241 The process would increase surface total alkalinity. It would work to increase ocean absorption of CO 2.
The Eastern Canadian Provinces (dark green) were the focal point in Canada's mitigation plan towards minimizing acid rain in the country, and lead to the implementation of the Eastern Canada Acid Rain Program in 1985. The United States-Canada Air Quality Agreement initially prioritized the reduction of acid rain within each country. [13]
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines and coal mines. [citation needed]
