Abstract：
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.
摘要：
在过去的40年中，16种EPAPAHs在环境和分析科学中发挥了非常重要的作用。但是现在有充分的理由质疑它们在许多情况下的效用，即使它们的使用是如此成熟和舒适。在这里，我们回顾了该列表如此成功的原因，以及为什么有时它被认为不太相关。缺少三组多环芳烃化合物（PAC）：较大且高度相关的PAHs，烷基化PAC，和含有杂原子的化合物。改善某些基质状况的尝试是已知的，在这里：（1）更新的PAHs清单（包括16种EPAPAHs），用于评估环境中的毒性（40种EnvPAHs）；（2）23种NSO杂环化合物和6种杂环代谢物的清单；（3）提出了10种氧基-PAHs和10种硝基-PAHs的清单，供将来实际使用。邀请科学界就这些清单进行讨论。尽管自1970年代引入16种EPAPAHs以来，知识状况已大大改善，此摘要还表明，需要对毒性进行更多研究，在环境和化学分析中的发生，特别是烷基化的PAHs，较高分子量的PAHs和取代的PAC，如氨基-PAHs，氰基-PAHs,等。.我们还建议对监管环境PAH分析的更新进行早就应该进行的讨论。
