Not only is terrestrial ecological risk assessment a relatively new field of science that has developed rapidly only since the mid-1980s, but it is also complicated by the fact that soil, in contrast to most aquatic environments, is very often on private lands and traded as real estate. In order to preserve the fertility and the productivity of the soil, control measures are to be taken in a herculean manner, thereby improving the health of all living beings.Īssessing the ecological risk of contaminated soil, pesticide application, sewage sludge amendment, and other human activities leading to exposure of the terrestrial environment to hazardous substances is a complicated task with numerous associated problems. In addition to this the enormous quantities of man-made waste products, sludge and other product" from new waste treatment plants even polluted water are also causing or leading to soil pollution.
We are losing this important natural resource by the accelerated erosion 10 some extent. All crops for human food and animal feed depend upon it. Due to this our precious natural resources like air, water and soil are getting polluted. Generally most pollutants are introduced in the environment by sewage, waste, accidental discharge or else they are by-products or residues from the production of something useful. A pollutant is something which adversely interfere with health, comfort, property or environment of the people. Pollution may be defined as an undesirable change in the physical, chemical and biological characteristics of air, water and soil which affect human life, lives of other useful living plants and animals, industrial progress, living conditions and cultural assets. There is urgency in controlling the soil pollution in order to preserve the soil fertility and increase the productivity. It is getting polluted in a number of ways. Soil being a "universal sink" bears the greatest burden of environmental pollution. Air, water and soil are being polluted alike.

Environment pollution is a burning topic of the day.
