Faulty sanitation, waste water and wrong methods of agriculture also induce soil pollution. Wastes like glass, plastic, human excreta, fuel residues, metals and vehicular products are common urban wastes. Plants absorb what they need and the excess goes into the soil. For example, exposure to soil containing high concentrations of benzene increases the risk of contracting leukaemia. Soil pollution occurs due to untreated disposal of industrial wastes into soil; it has high toxic contaminants, which leads to soil pollution. Some of them are metals, inorganic ions, salts, compounds formed by soil microbial activity, and decomposition of organisms. Sewage sludge.

Soil pollution is a result of penetration of harmful pesticides and insecticides, which on one hand serve whatever their main purpose is, but on the other hand bring about deterioration in the soil quality, thus making it contaminated and unfit for use later. They harm the development and existence of flora and fauna. i. Mining wastes often cover the top soil, thus spoiling a precious natural resource. This leads to lower crop yields in the future and thus may lead to food shortages. Soil pollution has a direct impact on food security and there is a direct link between the quality and safety of the food we eat and the level of soil contaminants. They can be in the form of gas, liquid or solid substances.

Land pollution refers to all forms of pollution affecting any type of soil: agricultural, forestry, urban, etc. They cause soil pollution by changing the pH of the soil. Soil pollution is when it contains an abnormal concentration of man-made chemical compounds that are potentially dangerous to the health of living beings and to the functioning of ecosystems. Agriculture is a big source of soil pollution. It has been reported that about 50 per cent of raw materials ultimately become waste products in industry and about 15 per cent of it are toxic. Some of the agricultural practices lead to soil pollution. Sewage Sludge Soil Pollution Nerve Agent Organophosphorus Compound Sulphur Mustard These keywords were added by machine and not by the authors. iv. Industrial wastes or byproducts are among the leading causes of soil pollution. Solid wastes may or may not cause diseases in man but are hazardous to health. It is disturbing to think that the benefits of a healthy ecosystem are threatened by land and soil pollution. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. Causes of soil pollution Published by Experts.

When these contaminants exceed the natural level, it starts polluting. According to an estimate, agricultural activities produce more than 1.8 billion tonnes of waste, each year. In addition to fertilisers and pesticides, soil condi­tioners and fumigants are used in agriculture. i. Acids harm growth of plants that are sown in these soils. This harms the flora and fauna that thrive on rainwater. i. Soils that have been spoiled due to excessive use of chemicals and pesticides become barren. When these wastes are left on the soil’s surface, they change the chemical composition of the soil. And some mix in soil through atmosphere and wind activity. The general composition of municipal wastes is as follows: It has been estimated that in 45 major cities of India, the quantity of average per day municipal wastes is about 50,000 tonnes. fertilizers and some agricultural practices.
