在过去的40年里，EPA的16种多环芳烃在环境和分析科学中发挥了特别大的作用，但现在有充分的理由质疑它们在许多情况下的效用，尽管它们的使用是如此的确定和舒适。在这里，我们回顾了为什么名单如此成功，为什么有时它被视为不太相关。三组多环芳香族化合物（PAC）缺失：较大且高度相关的PAH，烷基化PAC和含有杂原子的化合物。已知尝试改善某些基质的情况，并且在此：（1）用于评价环境中的毒性的PAH（包括16种EPA PAH）的更新列表（40种EnvPAH）;（2）23种NSO-杂环化合物和6种杂环代谢物的列表;和（3）提出10种氧代-PAH和10种硝基-PAH的列表以供将来实际使用。请科学界对这些清单进行讨论。虽然自20世纪70年代引入16种EPA多环芳烃以来，知识水平已得到显着提高，但本总结也表明，需要对毒性，在环境中的存在和化学分析进行更多的研究，特别是烷基化多环芳烃，高分子量多环芳烃和取代的PAC，如氨基多环芳烃，氰基多环芳烃等。我们还建议启动一个早就应该讨论的监管环境多环芳烃分析的更新。
The 16 EPA PAHs have played an exceptionally large role above all in environmental and analytical sciences in the last 40 years, but now there are good reasons to question their utility in many circumstances even though their use is so established and comfortable. Here we review the reasons why the list has been so successful and why sometimes it is seen as less relevant. Three groups of polycyclic aromatic compounds (PAC) are missing: larger and highly relevant PAHs, alkylated PACs, and compounds containing heteroatoms. Attempts to improve the situation for certain matrixes are known and here: (1) an updated list of PAHs (including the 16 EPA PAHs) for the evaluation of the toxicity in the environment (40 EnvPAHs); (2) a list of 23 NSO-heterocyclic compounds and 6 heterocyclic metabolites; and (3) lists of 10 oxy-PAHs and 10 nitro-PAHs are proposed for practical use in the future. A discussion in the scientific community about these lists is invited. Although the state of knowledge has improved dramatically since the introduction of the 16 EPA PAHs in the 1970s, this summary also shows that more research is needed about the toxicity, occurrence in the environment and chemical analysis, particularly of alkylated PAHs, higher molecular weight PAHs and substituted PACs such as amino-PAHs, cyano-PAHs, etc.. We also suggest that a long overdue discussion of an update of regulatory environmental PAH analysis is initiated.
