Effect on human health: The land when contaminated with toxic chemicals and pesticides lead to problem of skin cancer and human respiratory system. The toxic chemicals can reach our body through foods and vegetables that we eat as they are grown in polluted soil.

Application of synthetic fertilizers, manures, and wastewater treatment facilities can all contribute salt to surface and groundwater.
