Sediment and marine organism samples collected from Haizhou Bay and Lusi fishing ground in South Yellow Sea, China were analysed for polycyclic aromatic hydrocarbons (PAHs). The concentrations of 16 PAHs in marine organisms ranged from 127.43 to 350.53 ng/g dry weight (dw, Haizhou Bay fishing ground) and from 86.37 to 213.02 ng/g dw (Lusi fishing ground). The dominant compounds were 2- and 3-ring PAHs in marine organism tissues. The main PAH sources were found to be coal combustion. Specific habitat, feeding habit, trophic level and environmental differences may affect the PAH levels in marine organisms in our study area. The biota-sediment accumulation factor (BSAF) decreased with increasing PAH log K and BSAF values might differ in response to various environmental conditions and species. The excess cancer risk from PAH-contaminated seafood consumption was slightly higher than the guideline value (10), but much lower than the priority risk level (10).
从中国黄海海州湾和吕泗渔场采集了沉积物和海洋生物样本,对多环芳烃(PAHs)进行了分析。海洋生物中 16 种多环芳烃的浓度范围为 127.43-350.53ng/g 干重(海州湾渔场)和 86.37-213.02ng/g dw(吕泗渔场)。海洋生物组织中主要的化合物为 2-和 3-环多环芳烃。研究发现,煤燃烧是主要的多环芳烃来源。特定的生境、摄食习性、营养水平和环境差异可能会影响研究区域海洋生物中的多环芳烃水平。生物沉积物积累因子(BSAF)随着 PAH log K 的增加而降低,BSAF 值可能因各种环境条件和物种的不同而有所差异。受多环芳烃污染的海鲜消费导致的超额癌症风险略高于指导值(10),但远低于优先风险水平(10)。
