This study was conducted for assessment of human health risks due to intake of heavy metal cont aminated vegetables through determination of the heavy metals’ concentrations in soil and vegetables grown on it nearby Buriganga River, Dhaka, Bangladesh. Flame Atomi c Absorption Spectroscopy (AAS) was used to determine the concentrations of heavy metals. Moreover, Health Risk Index (HRI) of heavy metals was also calculated. The mean concentrations of heavy metals in soil were found in the decreasing order of Fe>Cr>Zn> Ni>Cu>Pb>Cd but in the case of roots and edible parts of vegetables, the mean concentrations of different heavy metals were as decreasing order of Fe>Cr>Zn>Pd>Ni>Cd>Cu and Fe>Cr>Zn>Pd>Ni>Cu>Cd respectively. In case of roots and edible parts of vegetables, except Cu and Ni all other heavy metal concentrations were higher than permissible limit. The HRI values of Cd, Cr, Fe, Pb and Zn were greater than 1 which indicated that contaminated vegetables were awfully detrimental to human health. Therefore, soil contamination as well as the heavy metal uptake into human body should be preven ted to avoid the health risk caused by heavy metal.
