陈腐垃圾的重金属污染特征及其潜在风险评价
Polluted characteristics and potential risk assessment of heavy metals in refuse
摘要
Abstract
Taking the different refuses from different landfill structures of Jiujiang city of Jiangxi province as the objects,the contents of heavy metals,such as Cr,Cu,Zn,As,Cd,Hg and Pb,were investigated.The results show that the concentrations of heavy metals are not beyond the three grades of Environmental Quality Standards for Soils (GB15618-1995) except Cr in anaerobic landfill D aged refuse.The concentrations of heavy metals of refuse from water recirculation are lower than leachate recirculation.Nemerow pollution index is at a clean level in semi-aerobic landfills,but is at a low ecological risk level in anaerobic landfills.The potential ecological risk assessment indicates the potential ecological risk index (RI) is at a low ecological risk level without distinct grade difference for different landfill structures and different leachate recirculation ways.关键词
