About pollution and types of pollution

1. Pollution

2. Pollution , the addition of any substance ( solid ,  liquid , or  gas ) or any form of  energy  (such as  heat , sound, or  radioactivity ) to the  environment  at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are  air pollution ,  water pollution , and  land pollution . Modern society is also concerned about specific types of pollutants, such as  noise pollution ,  light pollution , and  plastic pollution . Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human  health  and well-being. Definition

4. Air Pollution Air pollution , release into the  atmosphere  of various  gases , finely divided solids, or finely dispersed liquid  aerosols  at rates that exceed the natural capacity of the  environment  to dissipate and dilute or absorb them. These substances may reach concentrations in the air that cause undesirable health, economic, or  aesthetic  effects.

5. Noise Pollution Noise pollution , unwanted or excessive  sound  that can have  deleterious  effects on human health, wildlife, and environmental quality. Noise  pollution  is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities.

6. Soil Pollution Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.

7. Water Pollution  "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1] : 6   Water is typically referred to as polluted when it is impaired by  anthropogenic  contaminants. Due to these contaminants, it either no longer supports a certain human use, such as  drinking water , or undergoes a marked shift in its ability to support its biotic communities, such as fish.
