Abstract

Heavy metal pollution of soils is a major concern today because contamination of food chain considered as one of the major environmental pathways of human exposure leading to potential health risk.A pot experiment was carried out to investigate the transfer of Zn, Cu, Ni, Fe, Cd, Cr, Pb and Mn from non-contaminated and contaminated soils to jute leaves vegetable plant and to evaluate their associated health risk in the local population.The mean concentration of the heavy metals in jute leaves vegetable plants followed a decreasing order of Fe>Zn>Mn>Cu>Cr>Pb>Cd>Ni. Among the all heavy metals the highest transfer factor (TF) values was found for Cu (77.50-34.95) and the lowest TF value was observed for Ni(0-0.001) in jute leaves vegetables plant. The daily intake of metals (DIM) for a person through ingestion of jute leaves were in order of Fe>Mn>Zn>Cu>Cr>Pb>Ni>Cd. The values of health risk index (HRI) for the heavy metals were less than 1, therefore, no significant health risk is anticipated for the local consumers through ingestion of jute leaves.
