Environmental pollution indices: a review on concentration of heavy metals in air, water, and soil near industrialization and urbanisation.

Current industrial operations pollute the world's land, water, and air with heavy metals. Metals' environmental behaviour and geographical distribution near the industrial production. Heavy metal contamination potential was assessed using geoaccumulation index, enrichment factor, and other criteria. Heavy metal concentrations have increased due to industrial waste, geochemical shifts, agriculture, and mining. Modifying cell structure, heavy metals can harm and cause cancer. We need to develop and conduct comprehensive monitoring to determine if industrial production and mining is causing elevated heavy metal levels nearby area in the zone. This review shares contemporary heavy metal contamination on its nature, origin, and extent. [ABSTRACT FROM AUTHOR]
