The major air pollutants are acid rain, smog, fly ash, and indoor air pollutants. Acid rain is caused by when exhaust from burning fossil fuels combine with water vapor in the atmosphere and falls as rain or snow. Acid rain causes extensive damage to water, forest, soil, resources, and even human health. Many lakes and streams have been contaminated by acid rain and this had lead to a diminished population of fish. Acid rain has lead to the international limitations of sulphur and nitrogen oxide.
In some cases, acid rain is caused when industrial fumes mix with moisture in the atmosphere. Acids are then carried in clouds for long distances before they are deposited through rain, which indicates that forests and lakes far away from factories may be damaged by acid rain. Another significant cause of acid rain is automobile exhaust. Research has shown that although industrial emission makes up for most causes, sulfur dioxide from oil and coal combustion and nitrogen oxides produced from automobile engines have greatly intensified the problem. Electric power plants are also to blame for this issue.
Acid rain is rain that is more acidic than normal. Acid rain is a complicated problem. Caused by air pollution, acid rain's spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and from acid rain in the water. Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil.
Rainwater, snow, fog, and other forms of precipitation containing those mild solutions of sulfuric and nitric acids fall to the earth as acid rain. Acid rain is a much more complex problem then most people realize. Acid rain does not only drop dangerously high levels of acid into the ground directly affecting wildlife but it also mixes with other elements and compounds in the earth which then become harmful to the environment. For example aluminum is one of the most common metals on earth. It is stored in a combined form with other elements in the earth.
Sulfur Dioxide (SO2) is released by fossil fuels when they undergo combustion. Power plants and other fossil fuel burning industrial areas release various forms of nitrous oxides (Nox). These two chemical compounds combine with the water in the atmosphere to form what is known as acid rain. The main reason that has prompted legislation of industrial emissions from governments is because of the negative effects they can have on the environment. Acid rain is harmful to the environment because of it's low pH.
Acid rain can affect many substances including plants and animals. Even though it can affect all of these things, some people still think that it is not such a big deal. In my opinion, acid rain is very bad for the environment and we should do everything in our power to decrease the amount of it, and eventually put an end to it. The United States contributes around ⅔ of the total sulfur dioxide and ¼ of the total nitrogen oxides to the atmosphere from generating electric power by burning fossil fuels, such as coal. Acid rain forms from these gases when they react with water, oxygen and other gases in the atmosphere to form highly acidic compounds.
When this takes place, it is called acid rain. Acid rain contaminates the food, water, and air we breathe with acidic pollutants. It increases soil weathering and reduces the amount of nutrients in the soil, making the vegetation more vulnerable to disease, viruses, fungi, and insect pests. It increases the amount of toxic metals such as mercury, copper, and aluminum in untreated drinking water supplies. Acid rain also pollutes the air with a variety of pollutants such as carbon dioxide, carbon monoxide, hazardous air pollutants (HAPS), lead, nitrogen oxides, and sulfur dioxides.
It is known that without the atmosphere our planet would be inhabitable, but we continue to put numerous amounts of toxic waste into it. The burning of fossils fuels, produces gases that cause acid rain. Acid rain is harmful to forests, lakes, rivers, and any wildlife that is located in these areas. High standards of living, which developed countries are accustomed to, depends upon fossil fuels to withhold these standards. Therefore, they cause the pollutants that cause acid rain.
Acid Rain The topic of this paper is acid deposition, also known as acid Rain. Acid rain is precipitation, as rain, snow or sleet containing relatively high concentration of acid forming chemicals. As the pollutants from coal, smoke, chemical manufacturing, and smelting, that have been released into the atmosphere and combine with water vapor, the harmful deposition is created (http://dictionary.reference.com/browse/acid+rain). Acid rain affects many things greatly. Acid rain affects many different things and is very harmful to the environment.
Acid Rain Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain, snow, hail, or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth.
