Contemporary status of heavy metal contamination in soils affected by tannery activities, Ranipet, north India

Abstract

This study was focused to reveal the current heavy metal pollution in soil by tannery activities. This research was done at the site of the Tannery, Residential and normal agricultural areas in two layers of the soil samples at Ranipet, Vellore district. We evaluated only four heavy metals (Cr, Pb, Cd, Zn) contamination in the soil samples of study area. Flame AAS (Atomic Absorption Spectrometer) technique was used to determine these four heavy metals concentration. This result showed that heavy metals concentration is significantly higher in soil at the site of the tannery locality than in the normal agricultural and residential areas and also these four metals strength was found to be not very much significant changes in soil at the site of the normal agricultural and residential areas. These metals contamination in the soil is answerable for the support of harmfulness in farming crops and underground water.
