摘要
硝基多环芳烃(nitrated polycyclic aromatic hydrocarbons,NPAHs)是一类通过硝基取代的多环芳烃的衍生物,比母体多环芳烃具有更强的致突变、致癌、致畸毒性,并且广泛存在于各种环境介质中,对生态环境和人类健康具有潜在的危害和影响.又因其具有持久性和长距离迁移性,所以近年来受到研究者的广泛关注.本文基于当前国内外对环境中NPAHs的研究,系统的综述了NPAHs的环境赋存、来源、毒性效应及其健康风险评价,深入探讨了不同环境介质中的污染现状与来源.最后提出了现有研究的不足,并对NPAHs今后的研究方向进行了展望.
Nitrated polycyclic aromatic hydrocarbons(NPAHs)are nitrated derivatives of PAHs,showing higher mutagenic,carcinogenic,and teratogenic effects than that of their PAHs.NPAHs are widely distributed in the environment,such as air,soil and water,posing potential harms or influences to the ecological environment and human health.They have been aroused extensive attention in recent years,because of their persistence and long-distance transport ability.Based on the current research on NPAHs in the environment around the world,the occurrence,source,toxicity effects in environments and health risk assessment of NPAHs have been comprehensively reviewed in this article.The pollution status and sources of NPAHs in various environment matrix have also been discussed deeply.The remaining problems of recent research were proposed,as well as future research directions of NPAHs.
