title: Arsenic and heavy metals in leachate from a real landfill and a laboratory landfill.
abstract: A preliminary study, based particularly on Arsenic and some heavy metals determination (Cd, Cr, Hg and Pb) in three leachate tipologies produced from municipal waste landfill plant, lab-scale aerobic landfill, lab-scale anerobic landfill was undertaken. Leachate was collected and analysed monthly; samples were homogenized and then, all heavy metals were determined after mineralization, except for Hg, determined before mineralization, due to his high volatility. In all samples pH was measured. In general we can say that low concentrations of the elements analyzed were found in all kinds of landfills considered; in particular, in the lab-scale anaerobic reactors, where low pH values have been found, we have a more considerable mobilization of As and the others heavy metals, moreover due to the behaviour of these elements.
