These pollutants may be carried in clouds for long distances before falling, which means that forests and lakes far away from factories may be damaged by acid rain. Two of the major ingredients of acid rain are the chemicals sulphur dioxide [SO2] and nitrogen oxides [NOx]. When large quantities of these two particular chemicals come in contact with the atmosphere, they team up with moisture [H2O] to produce strong acids called sulphuric and nitric acid.
These two acids which are formed in the atmosphere, are very strong pollutants. Some air pollution as a matter of fact comes from natural sources, but most is human made. The burning of oil and coal by plants and factories, homes and cars, is the main source of chemicals that cause acid rain. Power stations and factories emit large amounts of sulphur dioxide and also nitrogen oxides, whilst car exhausts contain large amounts of nitrogen oxides.
When volcanoes erupt, they emit various gases which have been trapped under the ground, including sulphur dioxide. This can cause air pollution, which can then be made much worse by the addition of human-made emissions. The air in many towns and cities is overfull of harmful pollutants. In the northern hemisphere sulphur emissions are decreasing steadily, due to pollution controls in industry.
NOx emissions, however, are not yet in such steady decline. The acid from rain takes important minerals from the leaves of trees and from the soil. Acid rain also releases toxic metals from the soil which damage the roots of the trees. The trees are weakened, cannot grow properly and are attacked by viruses, fungi and pests.
Eventually the trees may die. Direct damage to trees occurs when SO2 blocks the pores on the leaves, through which the trees takes in the air they need to live. Forest floods that are affected by acid rain have high concentrations of metals like aluminium and lead. When animals drink from acidic lakes and dew that have been affected, the metals they take in may gradually poison them. There is an obvious link between acid rain and damage to human health. People can be harmed by breathing in the chemicals from dry deposition, causing chest illness.
When air pollution is breathed in as people walk along the street, it gets into their lungs. Once in the lungs, it acts like a poison, causing the airways in the respiratory system to become narrower. The essay will consider acid rain as the dependent variable.

The essay then details the effects acid rain has on the environment as well as the human population. The researcher conducted a survey on the measures being taken by governments and environmental agencies to tackle the issue. The essays contents are as follows;. Acid rain is a term that refers to all forms of acid precipitation. For a long time, pollution and hazardous discharges have been identified as the major causes of this form of precipitation.
Existing scientific research has linked acid rain to increased environmental degradation. Studies have identified acid rain as a contributing factor in decreased fish and wildlife population. Acid rain has also been blamed for contamination of lakes and rivers. Several cases of acid rain causing health issues in humans have also been reported.
Acid rain was first identified in the s in Sweden.
