Effects of Environmental Pollution in Industry (Case Study: Soil Pollution)

Soil pollution has increasing risks for human health and environment. Heavy elements are considered among the most important pollutants in the environment, which have been highly concerned in the last few decades. The accumulation of heavy elements in the soil, especially in agricultural fields, is gradual and the concentration of heavy elements can reach a level that threatens human food security. Every year, thousands of tons of these elements, which are caused by urban, industrial, and agricultural activities, enter the soil. The study of different researchers inside the country shows that the intensification of industrial activities, on one hand, and the non-compliance of environmental issues and standards by some of the industrial owners, on the other hand, has caused environmental pollution in some areas of the country. Soil is one of the important components of earth's bio-travel and plays an important role in the health of humans and animals. Soil not only plays an important role in the production of food and clothing, but also has a significant effect on maintaining the environmental quality. Therefore, soil contamination by chemicals is one of the most important biological issues. In the last few decades, with the progress of industry, the amount of toxic elements in the soil has been increased. Municipal and industrial effluents, solid wastes from various urban, industrial and agricultural activities, various fertilizers, and chemical poisons are important sources of soil pollution with toxic elements.
