Main Sources of soil pollution : pollution of soil caused by the various sources below mentioned Main Sources of soil pollution Read the carefully.
1. Physical Sources : The physical sources related with soil erosion and soil degradation. The natural factors of soil erosion includes high rainfall, changing temperature, wind, topography factor, lithographic factor, vegetation and soil characteristics. These favors accelerated by human activities
2. Biological Sources : The micro-organisms and unwanted plants degraded the quality and fertility of soil. The soil pollutant biological agent are pathogenic micro-organisms excreted by human beings and animals, enteric bacteria and protozoa. These micro-organisms enter the food chain and thus affect human bodies.
3. Air-borne Sources : The pollutants released in atmosphere by human activities affect on soil system. Fallout the atmospheric pollutants deposited tonics in soil. Sulphur emitted from factories causes acid rain which lower the PH of the soil. Sulphur dioxide (SOp emitted from the factories in UK and Germany has been responsible for widespread acid rain in the foray; Sweden, Finland. Huge quantity of particulate matters emitted from cement factories lime kilns coal mining, loading and unloading of coal,thermal power plants reach the soil and pollute soil by altering physical and chemical property.
4. Deposition of Solid Waste : Soil pollution involves the deposition of soled waste i e. cans, bottles, plastic containers in soil These components cannot break easily, when these materi accumulated in soil and it interfere organic life.
5. Chemical fertilizes and Pesticides : Excessive use of chemical fertilizers to boost agricultural profusion causes alteration in the physical and chemical properties of soils. The chemical pesticides,insecticides, herbicides destroy microorganisms including useful bacteria and thus lower down the quality of soil significantly. The world consumption of pesticides, Insecticides, herbicides has substantially Increased from 25,030 billion tonnes in 1965-66 to 100,000 billion tonnes during 1980 which shows four-fold increase within a period of 15 years.
