摘要

针对污染源的风险评估已被广泛用于分析污染源的风险，而不是污染物的含量，从而更准确地控制污染。然而，由于数据类型的限制，对源特异性生物效应的评估尚未见报道，这对生物保护具有重要意义。本研究对中国两个典型海湾蛤蚌中多环芳烃（PAHs）生物积累的健康风险和生物效应进行了综合评价。多环芳烃含量为122.68-367.21 ng/g d.w（干重），表明污染程度中等。增量终身癌症风险（ILCR）评估显示，食用蛤蜊的癌症风险较低。然而，综合生物标志物响应（IBR）分析表明，莱州湾的生物胁迫高于海州湾。正矩阵分解（PMF）确定了交通排放（燃烧后产物）、煤炭燃烧、不燃烧释放的石油产品和生物质燃烧是多环芳烃的来源。一种将偏最小二乘回归（PLSR）与IBR和PMF相结合的新方法使特定源的生物效应评估成为可能，与PMF- ilcr一起，结果表明交通排放是健康风险的主要来源，而石油是生物效应的主要来源。本研究强调了源特异性风险评价对制定有针对性的污染控制策略，特别是源特异性生物效应的重要性，强调渤海和黄海典型海湾多环芳烃污染源控制的重点应是：石油和天然气；交通比;煤比;生物质。

The source-specific health risk and biological effect assessment of PAHs in Mactra veneriformis from the Bohai Sea and Yellow Sea

Source-specific risk assessment has been widely used to analyze the source of pollution risk instead of pollutant content for more accurate control of pollution. However, due to limitations in data type, assessment of source-specific biological effect has not been reported, which is highly significant for organism protection. This study conducted a comprehensive assessment of the health risk and biological effect of polycyclic aromatic hydrocarbons (PAHs) bioaccumulated in the clam Mactra veneriformis from two typical bays in China. PAH levels ranged from 122.68 to 367.21 ng/g d.w. (dry weight), indicating a moderate level of pollution. Incremental lifetime cancer risk (ILCR) assessment revealed low cancer risks associated with clam consumption. However, the integrated biomarker response (IBR) analysis indicated higher biological stress in Laizhou Bay compared to Haizhou Bay. Positive matrix factorization (PMF) identified traffic emissions (post combustion products), coal combustion, petroleum products released without combustion, and biomass combustion as sources of PAHs. A novel approach that integrates partial least squares regression (PLSR) with IBR and PMF enable source-specific biological effect assessment possible, along with PMF-ILCR, the results showed traffic emissions as the primary source of health risks, while petroleum was the primary source of biological effects. This study emphasizes the importance of source-specific risk assessment for developing targeted pollution control strategies especially source-specific biological effect, highlighting that the priority of PAHs pollution source control for typical bays in the Bohai Sea and the Yellow Sea should be: Petroleum > Traffic > Coal > Biomass.

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
