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.
开展了一项初步研究，特别针对城市垃圾填埋场、实验室规模的好氧填埋场、实验室规模的厌氧填埋场产生的三种渗滤液类型中的砷及一些重金属（镉、铬、汞和铅）进行测定。每月收集并分析渗滤液；将样品均质化，然后除汞外，所有重金属在矿化后进行测定，汞由于挥发性高，在矿化前进行测定。测量了所有样品的pH值。总体而言，可以说在所考虑的各类填埋场中，所分析元素的浓度都较低；特别是在已发现低pH值的实验室规模厌氧反应器中，由于这些元素的特性，砷和其他重金属的迁移更为显著。
