Acid rain is a rain or any other form of precipitation that is unusually acidic , meaning that it has elevated levels of hydrogen ions low pH. It can have harmful effects on plants, aquatic animals, and infrastructure.

Effects of Acid Rain

Acid rain, or acid deposition, is a broad term that includes any form of precipitation that contains acidic components, such as sulfuric acid or nitric acid, according to the Environmental Protection Agency EPA. The precipitation is not necessarily wet or liquid; the definition includes dust, gasses, rain, snow, fog and hail. The type of acid rain that contains water is called wet deposition. Acid rain formed with dust or gasses is called dry deposition. The term acid rain was coined in by Scottish chemist Robert Angus Smith , according to the Royal Society of Chemistry, which calls him the "father of acid rain. In the s, scientists in the United States started studying the phenomenon, and in the s and early s, acid rain became recognized as a regional environmental issue that affected Western Europe and eastern North America. Though manmade pollutants are currently affecting most acidic precipitation, natural disasters can be a factor as well.

Acid rain is one of the consequences of air pollution. Gases produced from the burning of fuels react with the oxygen in the air and water vapour, transforming into acids that fall onto the earth's surface as rain. This acidification of the earth and surface water has devastating effects on ecosystems and poses a serious danger to living beings. The water and vapour emanating from Lake Kawah Ijen Indonesia , in the crater of the volcano of the same name, are lethal due to its high concentration of sulphuric acid. Volcanic eruptions, earthquakes, natural fires, lightning and some microbial processes release sulphur dioxide and nitrogen oxides into the atmosphere.

This report summarizes the potential impact of the acid precipitation phenomenon on human health. There are two major components to this phenomenon: the predepositional phase, during which there is direct human exposure to acidic substances from ambient air, and the post-depositional phase, in which the deposition of acid materials on water and soil results in the mobilization, transport, and even chemical transformation of toxic metals. Acidification increases bioconversion of mercury to methylmercury, which accumulates in fish, increasing the risk to toxicity in people who eat fish. Increase in water and soil content of lead and cadmium increases human exposure to these metals which become additive to other sources presently under regulatory control. The potential adverse health effects of increased human exposure to aluminum is not known at the present time. Full text is available as a scanned copy of the original print version.

Acid rain is defined as rain or another kind of precipitation that is abnormally acidic. This means that acid rain has heightened levels of something called hydrogen ions. Acid rain is known to have hurtful impacts on aquatic animals, plants and even infrastructure by a wet-disposition process. Chemicals in acid rain have been known to cause the paint to actually peel from surfaces. History of Acid Rain in the US Acid rain is a widely used phrase that really refers to the deposition of dry acidifying gases and particles and wet snow, rain, fog, sleet, dew or cloud water acidic components.

An ecosystem is a community of plants, animals and other organisms along with their environment including the air, water and soil. Everything in an ecosystem is connected. If something harms one part of an ecosystem — one species of plant or animal, the soil or the water — it can have an impact on everything else. The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released.

While the northeastern United States enjoys a relative abundance of freshwater, the quality of our water has degraded over the past century as a consequence of human activities. The deposition of acids is an important cause of this decline. Acid deposition is related to the combustion of fossil fuels, such as gasoline, oil, and coal, which releases sulfur dioxide SO 2 and nitrogen oxides NO X into the atmosphere. These gases mix with water vapor in the air and react to form acidic compounds, which fall to earth as rain or snow, sometimes hundreds of miles from their source. Over time, acid deposition, which includes acid rain, snow, and other kinds of acidic inputs, affects lakes and rivers.

Acid Rain: Causes, Effects and Solutions

Acid rain comes in many forms: rain, snow, sleet, hail, and fog wet deposition , and as acid particles, aerosols, and gases dry deposition. Acid deposition forms when sulfur dioxide SO 2 and nitrogen oxides NO x combine with moisture in the atmosphere to produce sulfuric acid and nitric acid. By the s, it became clear to scientists that acid deposition was devastating natural resources across New York.

Ellis B. Cowling, Rick A. Acid rain and atmospheric deposition have become dominant features of man-induced changes in the chemical climate of the earth. Detrimental effects predominate in many aquatic ecosystems, but the balance between beneficial and harmful effects in terrestrial systems remains uncertain.

Коммандер поднес его к уху. - В чем дело? - рявкнул он и замолчал, внимательно слушая собеседника. Сьюзан на какое-то время забыла про Хейла. Она молила Бога, чтобы Стратмору звонил Дэвид. Скажи мне скорей, что с ним все в порядке, - думала .

 - И быстро пробежала глазами информацию.

Он по-прежнему смотрел вниз, словно впав в транс и не отдавая себе отчета в происходящем. Сьюзан проследила за его взглядом, прижавшись к поручню. Сначала она не увидела ничего, кроме облаков пара. Но потом поняла, куда смотрел коммандер: на человеческую фигуру шестью этажами ниже, которая то и дело возникала в разрывах пара.

Стратмор покачал головой. - Это и мне сразу пришло в голову. Но послушай: канадец сказал, что буквы не складывались во что-то вразумительное.

 - Положите на место. Офицер еще какое-то время разглядывал паспорт, потом положил его поверх вороха одежды. - У этого парня была виза третьего класса.

 - Внезапно Беккер понял, что говорит чересчур громко. Люди на соседних койках приподнялись и внимательно наблюдали за происходящим. В дальнем конце палаты появилась медсестра и быстро направилась к .

 По-прежнему чепуха, - с отвращением скривился Джабба.  - Смотрите. Это просто бессмысленный набор букв… Слова застряли у него в горле, глаза расширились.  - О… Боже ты мой… Фонтейн тоже все понял.

Дверь повернулась и мгновение спустя выкинула его на асфальт. Беккер увидел ждущее такси. - Dejame entrar! - закричал Беккер, пробуя открыть запертую дверцу машины. Водитель отказался его впустить.

 Ну и ну… - Беккер с трудом сдержал улыбку.  - И что же ты ответила. Она ткнула его в ногу носком туфли. - Я сказала нет! - И, выдержав паузу, добавила: - И до вчерашней ночи это была правда. В глазах Сьюзан Дэвид был самим совершенством - насколько вообще такое .


Лицо ее побелело, глаза не отрываясь смотрели на застывший кадр, демонстрировавший неподвижное тело Дэвида Беккера, залитое кровью, брошенное на пол мини-автобуса. - Вы его убили! - крикнула .

    Effects of acid rain on Health: Acid​​ The harm to people from acid rain is not direct. Walking in acid rain, or even swimming in an acid lake, is no more dangerous than walking or swimming in clean water. However, the pollutants that cause acid rain sulfur dioxide (SO2) and nitrogen oxides (NOx) do damage human health.
