Diet is the main way for the human body to ingest polycyclic aromatic hydrocarbons (PAHs). In this study, the occurrence, dietary exposure, and health risks of 15 PAHs in 31 fried and grilled fish samples were investigated, which were collected from the Shandong Province of China. The results showed that benzo[a]pyrene (BaP) of 5 samples exceeded the European Union (EU) limit value. Naphthalene (NaP) and fluorene (Fle) were present in all samples, and the average concentration of ∑15PAHs was 91.1 μg/kg, with light PAHs dominated. The average contamination level of ∑15PAHs in fried and grilled fish was distributed differently, and there seemed to be more PAH contamination in the grilled samples. The results of the margin of exposure (MOE) suggested that PAH ingestion through fried and grilled fish did not imply significant toxicological concern for consumers in Shandong. The incremental lifetime cancer risk (ILCR) values for the consumption of fried and grilled fish were higher than 1 × 10, indicating a potential health risk in the adult population. The study provides baseline health information on PAH intake by residents due to dietary exposure to fried and grilled fish food products, suggesting that health risk monitoring of PAHs in such foods should be continually performed.
饮食是人体摄入多环芳烃（PAHs）的主要途径。本研究对采自中国山东省的31份油炸和烤鱼样本中15种PAHs的存在情况、膳食暴露及健康风险进行了调查。结果显示，5份样本中的苯并[a]芘（BaP）超过了欧盟限值。所有样本中均检测到萘（NaP）和芴（Fle），15种PAHs的平均浓度为91.1μg/kg，以轻PAHs为主。油炸和烤鱼中15种PAHs的平均污染水平分布不同，烤鱼样本中的PAH污染似乎更严重。暴露边际（MOE）结果表明，通过食用油炸和烤鱼摄入PAHs对山东消费者不存在明显的毒理学担忧。食用油炸和烤鱼的终生癌症风险增量（ILCR）值高于1×10，表明成年人群存在潜在健康风险。本研究提供了居民因膳食暴露于油炸和烤鱼食品而摄入PAHs的基线健康信息，建议持续开展此类食品中PAHs的健康风险监测。
