Soil pollution is defined by Wikipedia to be, “a part of land degradation caused by the presence of xenobiotic chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.”
Soil pollution gives rise to diseases such as headaches, coughing, chest pain, nausea, and skin or eye irritation. Studies have also proven that prolonged exposure to contaminated soil can lead to depression of the central nervous system and damage to vital organs. Much like water pollutants, common air pollutants are industrial wastes, agricultural wastes, nuclear wastes, mining and sewer sludge.
