| 摘 要： | 由于其致癌、致突变和致畸性，多环芳烃(PAHs)成为环境中一类重要的有机污染物。生物修复是一种经济和有效的修复污染土壤的方法。由于PAHs低的水溶性、强的吸附性，使其生物可利用性降低，不利于生物修复。添加表面活性剂是一种常见的加强PAHs生物利用性的方法。文章概述了近年来在多环芳烃生物修复中关于表面活性剂的研究进展。

| Abstract: | Polycyclic aromatic hydrocarbons are important organic contaminated compounds in the environment because of their carcinogenic, mutagenic, teratogenic properties. Bioremediation is a economical and effective method for the remediation of contaminated soil. PAHs have low bioavailability due to their low solubility and strong sorption. Adding surfactant is a common way to enhance PAHs bioavailability. This paper reviews the researches on surfactants applied in the PAHs bioremediation in recent years, particularly introduces the study on anionic surfactant, nonionic surfactant, biosurfactant. |
