Concentrations of 16 US EPA priority polycyclic aromatic hydrocarbons (PAHs) were measured in 15 marine wild organism species from South China Sea. The concentration (dry weight) of 16 PAHs ranged from 94.88 to 557.87ng/g, with a mean of 289.86ng/g. The concentrations of BaP in marine species were no detectable. The composition of PAHs was characterized by the 2- and 3-ring PAHs in marine species, and NA, PHE and FA were the dominant constituents. PAHs isomeric ratios indicated PAHs mainly originated from grass, wood and coal combustion, and petroleum. The human health risk assessment based on the excess cancer risk (ECR) suggested the probability of PAHs posing carcinogenic risk to human beings with consumption of marine organisms were negligible (probability<1×10).
在中国南海的 15 种海洋野生生物中，测定了 16 种美国环保署优先控制的多环芳烃（PAHs）的浓度。16 种 PAHs 的浓度（干重）范围为 94.88 至 557.87ng/g，平均值为 289.86ng/g。海洋物种中 BaP 的浓度未检出。PAHs 的组成以海洋物种中的 2-和 3-环 PAHs 为特征，萘、菲和芴是主要成分。PAHs 异构体比值表明，PAHs 主要来源于草、木和煤的燃烧以及石油。基于超额癌症风险（ECR）的人类健康风险评估表明，海洋生物消费对人类产生致癌风险的可能性可以忽略不计（概率<1×10）。
