Abstract

Kattedan is an industrial area near Hyderabad, Andhra Pradesh, India, contaminated with high concentrations of metals attributed to industrial sources (battery manufacturing, metal plating, textile and pharmaceuticals production and others). Twelve different locations in the Kattedan industrial area were assessed for concentrations of metals (Zn, Cr, Cu, Ni, Co, Pb, Hg, Cd, and As) in soils, waters, and vegetation. Application of sequential extraction technique for the soils revealed relatively high percentages of Zn, Cu, and Cr associated with mobile fractions, and correspondingly high concentrations of Zn, Cr, Cu, and Pb in forage grass samples and a high degree of bioavailability to humans. Human exposure assessment revealed high concentrations of Pb, Zn, and Cr in blood and urine samples from the residents of the study area showing a direct pathway and a potential for toxicological hazard due to heavy metal pollution.
