| Abstract: |
| The sources and ecological risk from sixteen polycyclic aromatic hydrocarbons in surface sediment in the Liaodong Bay were investigated from 2014 to 2015. The total concentrations of PAHs ranged from 88.5 to 347.1 ng/g, and the high value occurred in the central region of the Liaodong Bay. Cluster analysis identified two site clusters representing the coastal region affected by land-based pollution and the central region of the Liaodong Bay. Principal component analysis-multiple linear regression and diagnostic ratios suggested that PAHs contaminants originated from a mixture of combustion and petroleum sources, and the major was combustion sources. Based on sediment quality guideline, naphthalene, acenaphthylene, acenaphthene, phenanthrene and dibenz[a,h]anthracene may occasionally cause adverse biological effects in some stations. The toxic equivalent concentrations of carcinogenic PAHs indicated low carcinogenic risk for the Liaodong Bay. The ecological risk and toxic pollution levels of PAHs were higher in the central region than in the coastal region along the Liaodong Bay. |
| 中文摘要: |
| 研究于2014年和2015年对辽东湾表层沉积物中16种多环芳烃（PAHs）的来源和生态风险状况进行了调查和评估。辽东湾表层沉积物中16种PAHs的含量范围为88.5-347 ng/g，高值区主要分布在辽东湾中部海域。对辽东湾各站位沉积物中多环芳烃的含量进行中聚类分析结果表明，辽东湾的采样站位可分为两类，一类站位主要分布在辽东湾沉积物中部海域，另一类站位主要分布在受陆源污染较为严重的近岸海域。辽东湾表层沉积物中PAHs的来源为燃烧源和石油源的混合来源，其中燃烧源为主要来源。萘、苊、苊烯、菲、二苯并[a,h]蒽可能偶尔会引发有害生物效应；辽东湾表层沉积物为低致癌风险；辽东湾中部海域表层沉积物中PAHs的生态风险和毒性污染水平高于辽东湾近岸海域。 |
