Acid Deposition: A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere, often far from the original sources, ...
Acid Deposition: A comprehensive term for the various ways acidic compounds precipitate from the atmosphere and deposit onto surfaces. It can include: 1) wet deposition by means of acid rain, fog, and snow; and 2) dry deposition of acidic ...
A acid deposition
Definition (english only)
Any form of deposition on water, land and other surfaces that increases their acidity by contamination with acid pollutants, such as sulphur oxides, sulphates, nitrogen oxides and nitrates, ...
Acid Deposition
A complex atmospheric phenomenon that occurs when sulfur and nitrogen compounds are transformed by chemical processes in the atmosphere, often far from the original sources, and then deposited on earth in either wet or dry form (e.g.

Acid rain is a form of acid deposition in which sulphur dioxide (SO2) and nitrogen oxides (NOx) transform into acidic particles or vapors (such as sulphuric acid (H2SO4), ...
ACID RAIN Acid rain or "acid deposition" occurs when sulphur dioxide and nitrogen oxides that are released into the atmosphere by industries, towns and cities, ...
The process of adding lime to freshwater that has been polluted by acid deposition. Liming can reverse acidification by increasing water alkalinity.
Because various forms of acid deposition may have been stored in the frozen water, the melt can result in abnormally large amounts of acidity entering streams and rivers, sometimes causing fish kills.
Acid rain: Rainfall with a pH of less than 7.0. One source is the combining of rain and sulfur dioxide emissions, which are a by-product of combustion of fossil fuels. Also referred to as acid deposition and wet deposition.
reactions of nitric oxide in ambient air; major component of photochemical smog. Product of combustion from transportation and stationary sources and a major contributor to the formation of ozone in the troposphere and to acid deposition.
The gases present include sulfur dioxide as a result of the burning of coal for use as energy, and the particulate matter included calcium sulfide as a result of acid deposition. [Science of the Total Environment; v334-335; 435-445; 2004.] ...
It is a major component of photochemical smog, a product of combustion from transportation and stationary sources, and a major contributor to the formation of ozone in the lower atmosphere and to acid deposition.
