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.

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.

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. For example, volcanoes can cause acid rain by blasting pollutants into the air. These pollutants can be carried around the world in jet streams and turned into acid rain far from the volcano. After an asteroid supposedly wiped out the dinosaurs When it hit the air, it turned into sulfuric acid, generating a downpour of acid rain , according to a paper published in in the journal Nature Geoscience.

Even before that, over 4 billion years ago, it is suspected that the air may have had 10, times as much carbon dioxide as today. Geologists from the University of Wisconsin-Madison backed up this theory be studying rocks and publishing the results in a issue of the journal Earth and Planetary Science Letters.

That is a condition that will dissolve rocks," said study team member John Valley. Sulfur dioxide SO 2 and nitrogen oxides NOx released into the air by fossil-fuel power plants, vehicles and oil refineries are the biggest cause of acid rain today, according to the EPA.

Two thirds of sulfur dioxide and one fourth of nitrogen oxide found in the atmosphere come from electric power generators.

A chemical reaction happens when sulfur dioxide and nitrogen oxides mix with water, oxygen and other chemicals in the air. They then become sulfuric and nitric acids that mix with precipitation and fall to the ground. Precipitation is considered acidic when its pH level is about 5. The normal pH of rain is around 5.

Acid rain affects nearly everything. Plants, soil, trees, buildings and even statues can be transformed by the precipitation. Acid rain has been found to be very hard on trees. It weakens them by washing away the protective film on leaves, and it stunts growth. A paper released in the online version of the journal of Environmental Science and Technology in showed evidence of acid rain stunting tree growth. Geological Survey scientist who headed the effort.

Acid rain can also change the composition of soil and bodies of water, making them uninhabitable for local animals and plants. For example, healthy lakes have a pH of 6. As acid rain raises the level of acidity, fish tend to die off. Most fish species can't survive a water pH of below 5. When the pH becomes a 4, the lake is considered dead, according to National Atmospheric Deposition Program. There are several solutions to stopping manmade acid rain.

Regulating the emissions coming from vehicles and buildings is an important step, according to the EPA. This can be done by restricting the use of fossil fuels and focusing on more sustainable energy sources such as solar and wind power. Also, each person can do their part by reducing their vehicle use. Using public transportation, walking, riding a bike or carpooling is a good start, according to the EPA.

People can also reduce their use of electricity, which is widely created with fossil fuels, or switch to a solar plan. Many electricity companies offer solar packages to their customers that require no installation and low costs.

Potential human health effects of acid rain: report of a workshop

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.

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. The Catskill and Adirondack Mountains were particularly hard hit.

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.

Effects of Acid Rain

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.

The Effects of Acid Rain on Ecosystems

 - Не думаю, что он знал, что имеет дело с вирусом. Я думаю, он был введен в заблуждение. Бринкерхофф молчал. Мидж Милкен явно чего-то не поняла. - Это многое объясняет, - настаивала.  - Например, почему он провел там всю ночь.

Чатрукьян опустился на колени, вставил ключ в едва заметную скважину и повернул. Внизу что-то щелкнуло. Затем он снял наружную защелку в форме бабочки, снова огляделся вокруг и потянул дверцу на. Она была небольшой, приблизительно, наверное, метр на метр, но очень тяжелой. Когда люк открылся, Чатрукьян невольно отпрянул. Струя горячего воздуха, напоенного фреоном, ударила ему прямо в лицо.

WHAT IS ACID RAIN

Фонтейн молча обдумывал информацию. - Не знаю, ключ ли это, - сказал Джабба.  - Мне кажется маловероятным, что Танкадо использовал непроизвольный набор знаков.

 - НБ - это, конечно, не болтай. Вот такое агентство. На другой стороне авениды Изабеллы он сразу же увидел клинику с изображенным на крыше обычным красным крестом на белом поле. С того момента как полицейский доставил сюда канадца, прошло уже несколько часов.

Парень загородил ему дорогу. - Подними.

    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.

    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.
