📖 Assessment of heavy metal contamination. In Agriculture soil and irrigation water of Kasur.

Soil has become contaminated due to the addition of heavy metals and metalloids as a result of overexposure to rapid human activities such as emissions from industries, mine tailings, heavy metal wastes, utilization of manures, leaded gasoline and paints, sewage ooze, wastewater, burned coal residues, pesticides, spillage of petrochemicals, and environmental deposition. In terrestrial environments, metals are essential because oftheir impact on development and growth of plants [1]. Due to human activities, metal contamination level is increased at certain level. A dangerous level of heavy metals is not known in agricultural soils.
