The process of change in the chemical characteristic – acidity – of an environmental medium such as water, soils, ecosystems. It is characterized by a lowering of the pH (the measure of acidity) from its ‘normal’ basic (alkaline) values of around 5.5 to 7 towards lower values characterized as acid. This process has both natural and human causes although the later are help accountant for the speed with which acidification proceeds in the post-industrial era. Acidification concerns mostly water bodies (lakes and rivers), soils, and forest ecosystems.

Process by which soil or water becomes acidic

grida.no

Acidification occurs when certain gases emitted to the atmosphere by various processes react to enhance the natural acidity (pH) of precipitation. This precipitation (commonly termed “acid rain”) can have impacts upon plant life, rivers and lakes (and associated aquatic plants and animals) and man-made structures.

hess.com

An increase in acidity of a substance, referring in this case to such adverse environmental effects as acid rain or soil acidification.

csbsju.edu

A state in the soil lowered pH reduces the availability of molybdenum, phosphorus and sulphur but increases the probability of toxic levels of manganese and aluminium.

ees.adelaide.edu.au

Happamoituminen Försurning A natural process. The term is used to describe the loss of nutrient bases (calcium, magnesium and potassium) through the process of leaching and their replacement by acidic elements (hydrogen and aluminium). However, acidification is commonly associated with atmospheric pollution arising from anthropogenically derived sulphur (S) and nitrogen (N) as NOx or ammonia. Anthropogenically derived pollutant deposition enhances the rates of acidification, which may then exceed the natural neutralising capacity of soils and result in reduced pH values in soils and waters. Indirect damage to forests.

tkk.fi

The most important substances contributing to acidification are SO2 and NOX. These are released into the atmosphere when fossil fuels such as oil and coal are combusted. Air pollution with these substances leads to acid deposition (acid rain) that can pollute forests, lakes and rivers, as well as buildings.

dantes.info

The process by which rivers, lakes, rain, and other natural features become affected by excess acid. For example, nitrogen dioxide may form toxic organic nitrates, which contribute to acid rain and the acidification of ground and surface water.

deq.mt.gov

Increase in the acidity of a soil or watercourse due to human activity. This phenomenon can modify chemical and biological equilibria and seriously affect ecosystems.

burhani.com

The shift of an ecosystem in its physical characteristic towards higher acidity. Acidification is caused by anthropogenic input of acidifying compounds, manly sulphur and nitrogen compounds, into an ecosystem in excess of its ability to buffer the acidifying effects.

oekodata.com

Chemical alteration of the environment, resulting in hydrogen ions being produced more rapidly than they are dispersed or neutralized. Occurs mainly through fallout of sulfur and nitrogen compounds from combustion processes. Acidification can be harmful to terrestrial and aquatic life.

abb.at

The process of increasing the hydrogen ion concentration.

infoplease.com

Fall in the pH of soil and water due to precipitation containing dissolved ammonium compounds, sulphur and nitrogen oxides; an indirect cause of forest damage

english.forestindustries.fi

A build-up of hydrogen ions above normal levels; the process of becoming acidic.

dwb.unl.edu

The process whereby soils become acidic over time as a result of: the parent material; the addition of nitrogen to the soil by either fertiliser or legumes (where nitrogen is converted to nitrate); and/or the leaching of the soil by rainfall.

dpi.vic.gov.au

the decrease of acid neutralizing capacity in water or base saturation in soil caused by natural or anthropogenic processes.

www2.nature.nps.gov

Process of becoming more acid. pH 7 is neutral, above this is alkaline below pH 6 is acidic. i.e Acidification of the soil.

ecifm.rdg.ac.uk

reduction of the pH of soil, waterways and lakes.

svenska-mineral.com

Acidication of surface waters occurs where there are large inputs of acidic pollutants and where catchments have susceptible acid soils and underlying rock.

forestry.gov.uk

Acidification is caused by acid depositions of three main pollutants: sulfur dioxide (SO2), nitrogen oxides (NOx), and ammonia (NH3). Acid depositions have negative impacts on water, forests, and soil as well as causing damage to buildings and monuments. The main sources of emissions of acidifying substances are fossil fuel combustion used for energy production and transport.

The addition of acid (usually tartaric) during fermentation, frequently practised in hot climates where grapes tend to overripen and become deficient in acid.

The addition of acid (usually tartaric) during fermentation, frequently necessary in hot climates where grapes tend to over ripen and become deficient in acidity, thereby losing freshness.

bigredliquors.com

The addition of natural acids to wines that are too low. Tartaric acid is the most common but small amounts of citric acid are also sometimes added. The laws allowing or against acidification vary by country or production zone.
