A total of 32 surface sediment samples were collected from the East China Sea (ECS) to investigate the distribution of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments and evaluate their sources. The content of PAHs in the ECS surface sediments ranged from 2.3 ng/g to 57.8 ng/g. The source analysis revealed that the combustion of such fuels as petroleum is the main contribution source of PAHs in the ECS surface sediments, and oil spill is another important contribution source. The study also showed that the content of PAHs in the ECS surface sediments is low and does not cause adverse ecological risks.
共采集东海（ECS）32 个表层沉积物样品，调查表层沉积物中多环芳烃（PAHs）的分布情况，并评价其来源。东海表层沉积物中 PAHs 的含量范围为 2.3ng/g 至 57.8ng/g。源分析表明，石油等燃料的燃烧是东海表层沉积物中 PAHs 的主要贡献源，溢油是另一个重要贡献源。研究还表明，东海表层沉积物中 PAHs 的含量较低，不会造成不良的生态风险。
