Explanation:
Detailed explanation-1: -Environmental pollution caused by heavy metals is persistent, covert, and long-term (Ali et al., 2019). Because metals are nonbiodegradable and have a lengthy half-life, biological species are unable to decompose them, and they remain in their body parts and surroundings, posing health risks (Nabulo et al., 2011).
Detailed explanation-2: -Sources of heavy metals include mining, industrial production (foundries, smelters, oil refineries, petrochemical plants, pesticide production, chemical industry), untreated sewage sludge and diffuse sources such as metal piping, traffic and combustion by-products from coal-burning power stations.
