This research was aimed to reveal the Present-day heavy metal pollution in top soil by tannery activities. This research was done at the site of the Tannery, Residential and normal rural zone areas in two layers of the top soil samples at Vaniyambadi, Vellore district. We investigated only four heavy metals (Cr, Pb, Cd, Zn) adulteration in the top 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 top soil at the site of the tannery region than in the normal rural zone and residential areas and also these four metals strength was found to be not very much significant changes in top soil at the site of the normal rural zone and residential areas. These metals adulteration in the top soil is answerable for the support of harmfulness in farming crops and underground water.
