摘　　要：多环芳烃(PAHs)和重金属是土壤环境中有机和无机污染物的典型代表,二者来源广泛且能在土壤中长期存在,极易造成复合污染。研究表明,PAHs和重金属共存时会发生复杂的相互作用,使复合污染土壤修复往往比单一污染土壤修复更加困难。生物修复具备成本低、不造成二次污染、适用于大范围修复等优势,是极具应用前景的PAHs和重金属复合污染土壤修复技术。本文总结了土壤中PAHs和重金属复合污染的分布特点及交互作用,对PAHs和重金属复合污染土壤生物修复技术作用机理及研究进展进行了综述,并对PAHs和重金属复合污染土壤生物修复技术的发展提出了展望。Polycyclic aromatic hydrocarbons(PAHs) and heavy metals are representatives of soil organic and inorganic pollutants.They can easily cause combined contamination of soil because of the wide spread pollution sources and long-term existence in the soil.Complex interactions occur when PAHs and heavy metals coexist,which makes soil remediation more difficult than single contamination.Bioremediation has the advantages of low cost,no secondary pollution,which is suitable for remediation of large-area contaminated soil.It is a promising technology for the remediation of soil co-contaminated by PAHs and heavy metals.This paper describes the distribution characteristics of combined pollution and interaction of PAHs and heavy metals in soil,summarizes the mechanism and research progress of bioremediation technology for soil co-contaminated by PAHs and heavy metals,and puts forward the prospect for the development of bioremediation technology.
