The distribution, sources and risk assessment of 16 polycyclic aromatic hydrocarbons (PAHs) of surface sediments in the Luan River Estuary, China, have been investigated in the research. The results indicated that the total concentrations of 16 PAHs in surface sediments of the Luan River Estuary ranged from 5.1 to 545.1 ng g(-1)dw with a mean value of 120.8 ng g(-1)dw, which is relatively low in comparison with other estuaries around the world. The PAHs in the study area were mainly originated from pyrogenic sources. Besides, PAHs may be contaminated by petrogenic PAHs as indicated by the selected ratios of PAHs, the 2-tailed Pearson correlation analysis and principal components analysis at different sites. The result of the ecological risk assessment shows little negative effect for most individual PAHs in surface sediments of the Luan River Estuary, China.
本研究对中国滦河河口表层沉积物中16种多环芳烃（PAHs）的分布、来源及风险评估进行了调查。结果表明，滦河河口表层沉积物中16种PAHs的总浓度范围为5.1至545.1 ng g(-1)dw，平均值为120.8 ng g(-1)dw，与世界其他河口相比相对较低。研究区域内的PAHs主要来源于热解源。此外，根据不同站点PAHs的选定比值、双尾Pearson相关分析和主成分分析表明，PAHs可能受到石油源PAHs的污染。生态风险评估结果显示，中国滦河河口表层沉积物中大多数单一PAHs的负面影响较小。
