Remediation of Lead-contaminated Soil

HE Bing,YANG Xiao-e,WEI You-zhang (Institute of Agricultural Chemistry,College of Natural Resource and Environmental Sciences,Zhejiang University,Huajiachi Campus,Hangzhou 310029,China)  
A review with 38 references is given on the recent works covering soil contamination with Pb,the toxic effects of Pb on human health,and the remediation of soils contaminated with Pb.Golbal environmental contamination with heavy metals has accelerated dramatically in the past decades due to anthropogenic activities such as mining,smelting,and fertilization.Lead is one of the primary contaminats and is released mainly through offgas,sewage,and mining.Soils contaminated with lead elicit a challenge of world concern for lead that lead can be uptaken by plants and followed a transfer along the food chain and pose a human health problem.Up to now,available remediation technologies for Pb-polluted soils can be divided into two major groups:physicochemical remediation and bioremediation.The former on includes isolation and containment,solidification and stabilization,pyrometallurgical separation,chemical stabilization,electrokinetic remediation as well as soil leaching;the later one includes microbial remediation,biosorption and phytoremediation.
