烟熏鲣鱼是日本传统的加工鱼产品，含有大量的多环芳烃（PAHs）。其浓度通常超过欧盟法规规定的最高水平。虽然卤代多环芳烃（XPAH）由于其高毒性而引起了人们的关注，但没有关于烟熏干鲣鱼中XPAH存在的信息。在这项研究中，我们调查了2020年在日本市场购买的烟熏干鲣鱼中多环芳烃和XPAH的存在情况，并根据浓度和终身癌症风险增量（ILCR）评估了污染水平。多环芳烃的总浓度为419-1070 μg kg-1，XPAHs的总浓度为0.306-1.01 μg kg-1。由于烟熏干鲣鱼的消费量很低，因此通过饮食消费烟熏干鲣鱼的PAH 4的ILCR在其他烟熏食物中最低。木屑热板熏烟是减少多环芳烃污染的有效措施之一。
Smoke-dried bonito is a traditional Japanese processed fish product containing considerable amounts of polycyclic aromatic hydrocarbons (PAHs). Their concentrations generally exceed the maximum levels under EU regulations. Although halogenated PAHs (XPAHs) have attracted attention owing to their high toxicities, no information on the occurrence of XPAHs in smoke-dried bonito is available. In this study, we investigated the occurrence of PAHs and XPAHs in smoke-dried bonito purchased in the Japanese market in 2020 and evaluated the contamination levels in terms of concentrations and incremental lifetime cancer risks (ILCRs). The total concentrations of PAHs were 419–1070 μg kg–1and those of XPAHs were 0.306–1.01 μg kg–1. Because smoke-dried bonito is consumed in low amounts, the ILCR of PAH4 via dietary consumption of smoke-dried bonito was the lowest among those of other smoked foods. Smoking by hot-plate heating of wood chips should be one of the effective countermeasures to reduce PAH contamination.
