Abstract：
Substituted polycyclic aromatic hydrocarbons (SPAHs) are a type of emerging pollutant that widely exist in the environment, which also exhibit carcinogenicity, mutagenicity, and teratogenicity. These pollutants belong to toxic pollutants because of their similar structures to polycyclic aromatic hydrocarbons (PAHs). Their environmental behavior and ecological risk have attracted increasing attention. Based on a literature review, we found a new breakthrough in the source, distribution, behavior, and risk of SPAHs with comparison to traditional pollutants PAHs. This paper reviewed the current research progress on the environmental occurrence and photochemical behavior of SPAHs. Their sources, formation mechanisms, and distribution characteristics in the multimedia environment were highlighted, and the photochemical transformation kinetics, pathways, and affecting factors of SPAHs in water, ice, and other media were discussed. Furthermore, the research prospects about the environmental behavior and risk of SPAHs were proposed.
摘要：
取代多环芳烃(SPAHs)是一类广泛存在于环境中的新兴污染物,也表现出致癌性，致突变性,和致畸性。这些污染物由于其与多环芳烃（PAHs）相似的结构而属于有毒污染物。它们的环境行为和生态风险日益引起人们的关注。在文献综述的基础上，我们在源头上找到了新的突破，分布，行为，与传统污染物PAHs相比，SPAHs的风险。本文综述了SPAHs的环境发生和光化学行为的研究进展。他们的来源,形成机制，强调了多媒体环境中的分布特征，和光化学转化动力学，通路,以及影响水中SPAHs的因素，冰,和其他媒体进行了讨论。此外，提出了SPAHs环境行为与风险的研究展望。
