摘　　要：苯并(a)芘(benzo(a)pyrene,Ba P)是一种强致畸、致突变与致癌的多环芳香族(PAHs)碳氢化合物,是在环境领域中研究的热点有机污染物。目前,针对土壤有机污染物的治理技术,通常难以达到去除高环PAHs的修复要求,还需要进一步在治理技术方面深入研究。以苯并(a)芘作为高环PAHs的典型代表,对现阶段土壤苯并(a)芘污染状况进行分析,结合国内外研究现状介绍几种常见的苯并(a)芘污染土壤修复技术,总结各技术的机制原理及最新优化措施,并对苯并(a)芘污染土壤今后的发展方向进行展望,以期更好地实现高环PAHs污染土壤的治理。Benzo(a)pyrene(BaP)is a highly teratogenic,mutagenic and carcinogenic polycyclic aromatic hydrocarbon,which is a research hotspot of organic pollutant studied in the environmental field.The current treatment technologies for soil organic contaminants are usually difficult to meet the remediation requirements for removing high molecular weight PAHs.Therefore,this study uses BaP as a typical representative of high molecular weight PAHs to analyze the status of contaminated soil at this stage.Combined with the research status at home and abroad,several common BaP contaminated soil remediation technologies are introduced,and discussed the mechanism and the latest optimization measures of them.Finally,this paper forecasts the future development direction of BaP contaminated soil to realize the better control of it.
