Abstract

Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants of global concern due to their environmental abundance, persistence, and high toxicity. In the late 1970s, the US Environmental Protection Agency proposed a set of 16 priority PAHs (PAH16), which has a strong influence on the monitoring studies and toxicity testing of this pollutant class until now. However, PAHs exist in the environment as complex mixtures with a variety of unsubstituted and substituted compounds. Levels and/or toxicity of several high-molecular-weight (HMW) PAHs and PAH-related compounds (e.g., alkylated, oxygenated, nitrated, and heterocyclic derivatives) may be comparable to or even surpass those of PAH16, suggesting the need of a more comprehensive monitoring scheme for this pollutant class.

固体废物和环境样品中未取代和甲基化多环芳烃的表征及潜在有机化合物的气相色谱-质谱联用筛选

多环芳烃(PAHs)因其在环境中的丰度、持久性和高毒性而成为全球关注的有机污染物。20世纪70年代末，美国环境保护署提出了一套16种重点多环芳烃(PAH16)，对这类污染物的监测研究和毒性测试至今仍有很大影响。然而，多环芳烃以复杂的混合物形式存在于环境中，与各种未取代和取代的化合物混合在一起。几种高分子量(HMW)多环芳烃和多环芳烃相关化合物(如烷基化、氧化、硝化和杂环衍生物)的水平和/或毒性可能与PAH16相当甚至超过PAH16，这表明需要对这类污染物进行更全面的监测方案。非取代和甲基化多环芳烃的气相色谱-质谱联用研究及固体废物和环境样品中潜在有机化合物的筛选
