Environmental Pollution Effects on Health

The effects of environmental pollution on health can be classified on the basis of different types of environmental pollution i.e. water pollution, air pollution and soil pollution.

Effects of Water Pollution
Many water-borne diseases are caused by infections which result from the intake of polluted water. Amongst the different water-borne diseases, typhoid, hepatitis, diarrhea gastroenteritis, encephalitis, ascariasis, giardiasis and amoebiasis are the important ones. Respiratory problems, skin rashes are some of the other health problems caused by water pollution.

Effects of Air Pollution
Health problems resulting from air pollution are mostly associated with the respiratory tract. Bronchitis and asthma are some of the major problems; and an overall reduction in lung functioning is also the result of air pollution. Air pollution reduces the energy levels and is responsible for dizziness, headaches, cardiovascular problems, neurobehavioral disorders and even premature death in extreme cases. The ozone layer protects all living beings on earth from ultraviolet rays. Emission of greenhouse gases is the cause of the thinning of ozone layer. Therefore, air pollution affects life on earth in different ways.

Effects of Soil Pollution
The pollution of soil with the element lead is one of the major problems since, it affects the health of children. Damage caused to the brain in the developmental phase of children is also the result of lead pollution. Mercury is responsible for damaging the kidneys. Functioning of the liver is greatly affected by cyclodiene, a kind of insecticide. Insecticides are known to enter the food chain and hamper the health of all the living elements of the food chain it enters.

The different environmental pollution effects on flora, fauna and human beings were presented in this article; it gave information about how does pollution affect the environment. Pollutants have a direct impact on the quality of life and often have disastrous consequences. Industrialization is the main cause of the addition of pollutants to the environment. Although it is not possible to completely remove the pollutants from our environment , we should try to keep the emission of pollutants under control, thereby taking a step towards curbing pollution.
