多环芳烃(PAH)衍生物，如硝基、氧基、卤代和羟基化的多环芳烃，是由多环芳烃形成的或作为其转化产物产生的有机化合物。这些衍生物比母体多环芳烃具有更强的毒性和蓄积性，这需要对其转化机制和环境行为有进一步的认识。发展多环芳烃衍生物的分析方法是全面研究其转化机理和评价其环境风险的关键。在本研究中，我们讨论了固体和水样中多环芳烃衍生物的前处理方法，包括提取、纯化和衍生化。我们还比较了两种广泛使用的联用分析技术，包括GC-联用和HPLC-联用质谱法。总结了自2010年以来研究中报道的多环芳烃衍生物的环境特性。最后，对未来的研究提出了几点研究展望。本文综述了近年来多环芳烃衍生物的分析技术，并提出了满足不同分析要求的技术选择思路。
Polycyclic aromatic hydrocarbon (PAH) derivatives, such as nitro-PAHs, oxy-PAHs, halogenated PAHs, and hydroxylated PAHs, are organic chemicals formed with or produced as transformation products of PAHs. The derivatives are more toxic and accumulative than parent PAHs, which require further recognition on their transformation mechanisms and environmental behaviors. Development of analytical methods for PAH derivatives is essential for comprehensively studying their transformation mechanisms and evaluating their environmental risks. In this study, we discuss pretreatment methods, including extraction, purification, and derivatization for PAH derivatives in solid and aqueous samples. We also compare the widely used two coupling analytical techniques, including both GC- and HPLC-coupled mass spectrometry methods. The environmental characteristics of PAH derivatives reported in studies since 2010 are summarized. Finally, several research prospects are raised for future studies. This review provides a comprehensive understanding of recent analytical techniques for PAH derivatives, and ideas for technique selection to meet different analytical requirements.
