It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
Soil particles picked up during wind erosion of soil are a major source of air pollution, in the form of airborne particulates—"dust". These airborne soil particles are often contaminated with toxic chemicals such as pesticides or petroleum fuels, posing ecological and public health hazards when they later land, or are inhaled/ingested.
Human-induced land degradation and water scarcity are increasing the levels of risk for agricultural production and ecosystem services. [1] The United Nations estimate that about 30% of land is degraded worldwide, and about 3.2 billion people reside in these degrading areas, giving a high rate of environmental pollution. [2]
Pollution by heavy metals decreases the soil organic matter composition resulting in a decline in soil nutrients which then leads to a decline in the growth of plants or even death. [ 197 ] Besides creating environmental damage, the contamination resulting from leakage of chemicals also affect the health of the local population. [ 198 ]
