چکیده مقاله:

Background & Aims of the Study: Leachate production is a major problem for solid wastelandfills and causes important threat to health public and environment. One of the typicalproperties of heavy metals is that they cannot easily decompose in the environment. Theaim of this study was to measure of heavy metals concentrations in old-age leachate fromQazvin landfill site, Iran.Materials & Methods: Sampling was conducted during summer 2014 from the leachatewhich was produced in Qazvin landfill site in Lia park. The concentration of heavy metalsincluding Zn, Ni, Hg, Cu, Co, Cd, Cr, Fe, Mn, and Pb along with pH were measured basedon the standard method.Results: The results of this study indicated the leachate generated from Qazvin landfill site,contains large amounts of different heavy metals. The mean concentration of Zn, Ni, Hg,Cu, Co, Cd, Cr, Fe, Mn, and Pb were 2.8, 0.2, 0.01, 0.1, 0.08, 0.04, 0.04, 4.6, 1.4 and 1.3ml/L, respectively. Also pH value was 8.4. The concentration of Fe, Pb, Zn and Mn in thelandfill leachate was higher than the permissible standard value which was suggested byDepartment of Environmental (DOE).Conclusion: The results suggest that we can achieve the permissible standards to dischargeeffluents into the surface water, absorbing well and agricultural irrigation by applyingbiological and physicochemical methods.
