铅污染土壤的修复技术

综述了铅对土壤的污染及其修复技术。目前应用于污染土壤的修复技术可分为物理化学修复技术和生物修复技术。物理化学修复技术又可分为隔离包埋技术，固化稳定技术，Pyrometalluryical separation，化学稳定技术，电动修复技术等；生物修复技术可分为微生物修复技术和植物修复技术等。以期进一步推动铅污染土壤的治理和修复工作。

Remediation of Lead-contaminated Soil

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.
