摘要：

为了解和评估人类活动对河口海岸带沉积物质量的影响,在长江口及邻近东海海域采集87个表层沉积物样品,研究了16种优控多环芳烃（polycyclic aromatic hydrocarbons,PAHs）和8种含氧多环芳烃（oxygenated PAH,O-PAHs）的含量与组成及空间分布特征,解析它们的主要输入来源及潜在生态风险。研究发现,沉积物中检出16种PAHs和7种O-PAHs,其中Σ₁₅PAHs（不包括萘）质量分数范围为5.53—415 ng∙g^-1,苯并[b]荧蒽、苯并[a]蒽、菲和芘是主要PAHs;Σ₇O-PAHs质量分数范围为8.93—158 ng∙g^-1,主要成分为蒽醌。基于PAHs诊断参数,研究区域沉积物中PAHs主要来源生物质和化石燃料的燃烧。从空间分布看,PAHs和O-PAHs主要分布在长江入海口、杭州湾入海口以及长江口泥质区和浙江—福建沿岸泥质区沉积物中,并随着向东海延伸,质量分数呈现由西南向东北逐渐下降的趋势。研究结果表明,陆源PAHs和O-PAHs主要经长江及其支流、钱塘江输入研究区域;此后在多重洋流共同作用下,吸附于颗粒物上的PAHs和O-PAHs沉降于泥质区;区域繁忙的船舶运输对沉积物中PAHs和O-PAHs分布有重要贡献。采用沉积物质量标准评估生态风险,结果表明苯并[a]蒽和二苯并[a, h]蒽单体会对底栖生物造成一定的生态风险,其余单体以及ΣPAHs综合生态风险有限。

Abstract:

To understand and assess the impact of human activities on sediment quality in estuarine and coastal zones, 87 sediment samples were collected from the Yangtze River Estuary and the adjacent East China Sea. The occurrence and distribution of 16 priority polycyclic aromatic hydrocarbons (PAHs) and 8 oxygenated polycyclic aromatic hydrocarbons (O-PAHs) were investigated, and potential ecological risks were assessed based on Sediment Quality Guidelines. The results indicated that 16 PAHs and 7 O-PAHs were detected in the sediments in the studied region. Total concentrations of 15 PAHs (∑₁₅PAHs, with exception of naphthalene due to its high volatility) varied in the range of 5.53-415 ng∙g^-1 with benzo [b] fluoranthene, benzo(a)anthracene, phenanthrene, and pyrene as the predominant PAHs. Simultaneously, total concentrations of O-PAHs (∑₇O-PAHs) ranged from 8.93 ng∙g^-1 to 158 ng∙g^-1 predominated by anthraquinone. PAHs in the study region mainly originated from the combustion of fossil fuel and biomass, and were discharged into the study region via Qiantang River, Yangtze River and its tributaries, after that deposited into sediment under complex impacts from currents. The results also indicated that O-PAHs shared similar emission sources of the parent PAHs. Higher levels of PAHs and O-PAHs were found at sampling sites adjacent to the Yangtze River Estuary and its mud area. Their levels tended to decrease when getting closer to the coastal to East China Sea, or in the interface of Hangzhou Bay and mud area along Zhejiang-Fujian Coastal Current. Risk assessment revealed that low ecological risks were posed by Benzo(a)anthracene and Dibenzo(a, h)anthracene. Overall, the sediment-dwelling organisms in the region are susceptible to low ecological risks.

Key words: PAHs, oxygenated PAH, Sediment, the Yangtze River Estuary, East China Sea, ecological risk
