HEALTH RISK ASSESSMENT OF HEAVY METALS IN DRINKING WATERS

Heavy metal concentrations of Pb, Cd, Zn, Ni, Cr, Mn, and Cu in drinking water collected from capture groundwater stations were determined. These values were correlated with physicochemical indicators. Concentrations of all metals were lower than maximum admitted limits established by Romanian Law 311/2004. The health risk index values for all determined elements (Pb 0.029 +/- 0.009, Cd 0.008 +/- 0.011, Zn 0.012 +/- 0.002, Ni 0.003 +/- 0.001, Cr 0.012 +/- 0.009, Mn 0.006 +/- 0.001, and Cu 0.017 +/- 0.004) were also found to be lower than the safe limit values.
