The sources, distribution and risk of 51 organic micropollutants (OMPs) in the Cantabrian coastal environment (NW Spain) were evaluated. Gas chromatography coupled to tandem mass spectrometry was used to determine polycyclic aromatic hydrocarbons, polychlorinated biphenyls, organochlorinated pesticides, polybrominated diphenyl ethers, phthalates esters, bisphenol A and alkylphenols. 45 OMPs were detected in coastal/estuarine waters. Wastewater treatment plant effluents and emissary discharges were identified as the main sources of contamination. The accumulation of OMPs in sediments and the bioaccumulation in 21 days caged mussels were also assessed. Chemical results were combined with the "Combined Monitoring-based and Modeling-based Priority Setting Scheme" COMMPS procedure for risk assessment analysis. Finally, the chemical status of the different sampling locations was estimated using site risk indexes. Those indexes can be conveniently displayed in quality geographical maps and are considered a valuable tool for the environmental management and risk assessment of the region under study.
评估了西班牙西北部坎塔布里亚沿海环境（Cantabrian coastal environment）中 51 种有机微量污染物（organic micropollutants，OMPs）的来源、分布和风险。采用气相色谱-串联质谱联用技术测定了多环芳烃、多氯联苯、有机氯农药、多溴联苯醚、邻苯二甲酸酯、双酚 A 和烷基酚。在沿海/河口水中检测到 45 种 OMPs。污水处理厂的废水和排放口被确定为主要的污染源。还评估了 OMPs 在沉积物中的积累和在 21 天笼养贻贝中的生物累积。将化学结果与基于综合监测和基于模型的优先级设置方案（Combined Monitoring-based and Modeling-based Priority Setting Scheme，COMMPS）程序相结合，进行风险评估分析。最后，使用地点风险指数估计了不同采样地点的化学状况。这些指数可以方便地显示在质量地理地图上，被认为是该研究区域环境管理和风险评估的有价值工具。
