Types of Pollution

Types of Pollution

3.Waste pollution:The presence on land or water of solid material, organic or inorganic, which has no beneficial qualities.

4.Chemical pollution:The presence in plants and animal tissues including feed or foodstuffs, of adulterant chemicals which have no beneficial effect.

5.Thermal pollution:The discharge into the environment of stream of air or water which is at a different temperature from that of the environment at the point of discharge or downpour of this point.

6.Land pollution:Deforestation, industrialization, urbanization and indiscriminate use of fertilizers causes alarming degradation of earth and environment.

7.Oil pollution:Crude oil is another major pollutant particularly of the sea’s.
