Give various sources and harmful effects of soil pollution.
Sources of soil pollution:
-
Soil pollution is caused by solid wastes and chemicals made by humans. This solid waste has two types of pollutants:
i. Degradable pollutants include domestic wastes and sewage that decompose easily.
ii. Non-degradable pollutants which
are not degraded and persist in the
environment,
Example: plastics, inorganic metallic compounds, and many more.
-
Pulp and paper mills, sugar mills, and many industries produce complexes that are major contributions to soil erosion.
-
Industrial furnaces and thermal power stations produce fly ash, which is a gray, powdery residue of unburnt material which gets mixed with soil and causes soil pollution. This fly ash affects the growth of crop plants and also decreases crops of orchards.
-
The slag heaps from mines spoil the beauty of sites of mines.
Effects of soil pollution:
-
Soil pollution affects the health of humans, plants, and animals as the chemicals pass into them from soil by food.
-
Crops or plants grown on such contaminated soil absorb toxic material from the soil which will decrease the agricultural output of a land and it also decreases the soil fertility.
-
Soil pollution kill the useful bacteria in the soil and can also lead to desertification of cultivable land.
