Pesticides are synthetic toxic chemicals that definitely kill different types of pests and insects causing damage to agriculture but it has many ecological repercussions. Hence this led to the introduction of other harmful chemicals such as Aldrin and Dieldrin. Moreover, pests became resistance to DDT due to the chemicals regular use. However, everyone gradually the adverse effects of this chemical which led to the ban of this chemical in many parts of the world including India. Hence, post-war, people started using it as pest control in agriculture for killing rodents, weeds, insects, etc and avoiding the damages due to these pests. Therefore, it was used for controlling many diseases. However, DDT was found to be extremely useful for malaria control and as pest control of many insects during World War II. ![]() Pesticidesīefore World War II, the chemical nicotine chemical present in the tobacco plants was used as the pest controlling substance in agricultural practices. However, it mostly boils down to the activities of the human that causes the majority of soil pollution such as heavy industries, or pesticides in agriculture. Soil pollution can be natural or due to human activity. This soil erosion refers to soil pollution. Moreover, the presence of excess chemicals will increase the alkalinity or acidity of soil thus degrading the soil quality. Thus, due to many different human activities such as overuse of pesticides the soil will lose its fertility. The primary cause of soil pollution is a lack of awareness in general people. The soil contamination can occur due to the presence of chemicals such as pesticides, herbicides, ammonia, petroleum hydrocarbons, lead, nitrate, mercury, naphthalene, etc in an excess amount. However, mostly it is due to human activities. Soil contamination or soil pollution can occur either because of human activities or because of natural processes. It occurs when the pollutants causing the pollution reduce the quality of the soil and convert the soil inhabitable for microorganisms and macro organisms living in the soil. Soil pollution refers to anything that causes contamination of soil and degrades the soil quality. However, unintended pesticide dispersion into the environment (often referred to as “pesticide drift”) raises a number of environmental issues, including water and soil degradation. Pesticides are chemicals (or chemical mixes) that are used to kill or prevent pests from reproducing.Industrial Waste Soil contamination can come from the dumping of industrial waste into soils. ![]() Coke (coal) production, automobile emissions, cigarette smoke, and shale oil extraction are all sources of PAHs in the soil.PAHs (polycyclic aromatic hydrocarbons) are a class of organic chemicals where only carbon and hydrogen atoms are present. ![]()
