本研究调查了中国南海海洋生物中的16种优先多环芳烃（PAHs）的水平和组成，并评估了其潜在健康风险。结果显示，总PAHs的污染水平在3.56到392.21 ng/g dw之间。值得注意的是，4环PAHs占总PAHs的主导成分（58.02％），其中吡啶是所有物种中最丰富的同系物。有趣的是，我们的研究结果表明，食用这些生物可能具有较低的非癌症风险。然而，大部分物种中检测到苯并[α]芘，浓度范围从不可检测到11.24 ng/g dw不等。与所研究地区的海鲜消费相关的个体终身癌症风险水平在1.10×10-5到1.52×10-5之间，强调了潜在的癌症风险，需要特别关注。这些研究结果强调了优先考虑致癌化合物而非总PAHs，并强调了对海鲜中PAH污染的持续监测的重要性。版权所有 © 2023 Elsevier Ltd. 保留所有权利。

This study investigated the levels and composition of 16 priority polycyclic aromatic hydrocarbons (PAHs) in marine organisms from South China Sea and assessed their potential health risks. The results revealed that the pollution levels of total PAHs ranged from 3.56 to 392.21 ng/g dw. Notably, 4-ring PAHs constituted the predominant fraction (58.02 %) of the total PAHs, with pyrene being the most abundant congener across all species. Intriguingly, our findings suggested that consuming these organisms might pose a low non-cancer hazard. Nonetheless, benzo[a]pyrene was detected in most species, with levels ranging from non-detectable to 11.24 ng/g dw. The individual lifetime cancer risk levels associated with seafood consumption in studied regions ranged from 1.10 × 10-5 to 1.52 × 10-5, highlighting a potential cancer risk that warrants special attention. These findings emphasize the need to prioritize carcinogenic compounds over total PAHs and underscore the importance of continuous monitoring of PAH pollution in seafood.Copyright © 2023 Elsevier Ltd.
