摘要: 土壤污染已经成为全球性的重要环境问题之一。多环芳烃(polyaromatic hydrocarbon,PAHs)和多氯联苯(polychlorinated biphenyl,PCBs)等有机污染物具有潜在的致癌性和致畸性,其修复研究近年来受到广泛关注。微生物修复技术既经济且无二次污染,具有其他修复技术难以比拟的优势。结合最新文献,综合阐述了目前利用微生物修复这2种有机污染物的研究进展及存在问题,重点介绍了降解微生物的筛选、降解过程和机理的研究成果,综合评述了微生物修复有机污染土壤的发展方向和发展趋势。

Abstract: Soil pollution has become a global environmental issue in recent years, and the remediation for polyaromatic hydrocarbon (PAHs) and polychlorinated biphenyl (PCBs) has been more aware because of their potential carcinogenicity and teratogenicity. Bioremediation is a very promising new environmental technology in light of its economic and no secondary pollution characteristics. Based on up-date publications worldwide, this paper mainly review PAHs and PCBs pollution remediation by microbial procedures in soil by focusing on introduction of development on screening microbial species which can degrade and adsorption these two organic pollutants, as well as on the methods and mechanism of microbial remediation to proceed systematically integrated effect. At last, we sum the trend of this researching field in China.
