摘　　要：土壤环境中的铅(Pb)污染日趋严重,对农作物和人类健康产生巨大影响。介绍了土壤中Pb的来源、形态,并且阐述土壤因子对Pb形态的影响;探讨了Pb转移到植物体内的途径及影响,对植物的影响及危害和对人体的毒理效应及作用机制、修复治理土壤Pb污染的几种修复技术进行分析阐述,基于以上的一些论述内容,对未来的污染治理方向提供一些参考和建议,以期为该领域内的学者提供一些借鉴。Lead( Pb) pollution on soil environment is becoming more and more serious,which brings about a great impact on crops and human health.The source and speciation of Pb in the soil is introduced and the influences of soil factors on speciation of Pb is described.The ways that Pb migrates into the plant body and their influences on the plant are explored.This paper also reviews the influences and harm of Pb pollutants to the plant,the toxicology effect and action mechanism on human body,several remediation techniques for the soil polluted by Pb.Finally,it provides some references and suggestions about pollution control direction in the future.
