  2. Freshwater acidification - Wikipedia

    en.wikipedia.org/wiki/Freshwater_acidification

    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.

  3. Acid rain - Wikipedia

    en.wikipedia.org/wiki/Acid_rain

    Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.

  4. Smog - Wikipedia

    en.wikipedia.org/wiki/Smog

    HNO 3, nitric acid, is a sticky compound that can easily be removed onto surfaces (dry deposition) or dissolved in water and be rained out (wet deposition). Both ways are common in the atmosphere and can efficiently remove radicals and nitrogen dioxide.

    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 ...

  7. Lake - Wikipedia

    en.wikipedia.org/wiki/Lake

    An acid lake contains water with a below-neutral pH of less than 6.5. A lake is considered to be highly acidic if its pH drops below 5.5, leading to biological consequences. A lake is considered to be highly acidic if its pH drops below 5.5, leading to biological consequences.

    Dry deposition can be computed on ground and also on ceil/roof and on lateral faces of obstacles. Dispersion under generalized geometries like arches, tunnels and walkways can be performed. Dense gas dispersion is simulated using five conservation equations (mass, energy, vertical momentum and two horizontal momenta) based on Glandening et al ...

    Jizera Mountains in Central Europe in 2006 Tree dieback because of persistent drought in the Saxonian Vogtland in 2020. Forest dieback (also "Waldsterben", a German loan word, pronounced [ˈvaltˌʃtɛʁbn̩] ⓘ) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or conditions like acid rain, drought, [1] and more.
