欧盟海洋战略框架指令的描述符9(D9)是指定义的海洋区域或次区域的鱼类和其他海产品中的污染物水平符合人类健康阈值。这需要在依赖商业渔业或设计用于监测人类暴露的程序时通常难以获得的地理参考样本。本研究检查了在这种情况下是否可以使用德国环境标本库(ESB)的蓝贻贝(Mytilusedulis)和eelpout(Zoarcesviviparus)鱼片的地理参考样本。ESB样品的适用性,程序,和分析方法是根据D9要求进行评估的。根据D9相关污染物Pb的ESB数据,Cd,Hg,∑4PAHs,PCDD/Fs,二恶英样(dl)-多氯联苯,以及指示非dl-多氯联苯和潜在相关物质TBT,全氟辛烷磺酸,PBDE,和六溴环十二烷,在北海和波罗的海的ESB站点评估了D9的良好环境状况。总体评估表明,ESB样品适用于D9评估,但仅限于北海和波罗的海的沿海地区。在长达30年的时间里,D9相关污染物的浓度远低于允许人类食用的最大水平。
Descriptor 9 (D9) of the European Union Marine Strategy Framework Directive refers to the compliance of contaminant levels in fish and other seafood of a defined marine region or subregion with human health threshold values. This requires georeferenced samples that are often difficult to obtain when relying on commercial fisheries or programs designed for monitoring human exposure. The present study examines whether georeferenced samples of blue mussel (Mytilus edulis) and eelpout (Zoarces viviparus) fillet of the German environmental specimen bank (ESB) can be used in this context. The suitability of the ESB samples, procedures, and analytical methods is evaluated with respect to D9 requirements. Based on ESB data for the D9 relevant contaminants Pb, Cd, Hg, ∑4 PAHs, PCDD/Fs, dioxin-like (dl)-PCBs, and indicator non-dl-PCBs and the potentially relevant substances TBT, PFOS, PBDE, and HBCDD, the Good Environmental Status for D9 is assessed at the ESB sites in the North and Baltic Seas. The overall evaluation indicates that ESB samples are suitable for D9 assessment with the limitation that only coastal areas of the North and Baltic Seas are covered. Over a period of up to 30 years, concentrations of the D9 relevant contaminants were well below the maximum levels allowed for human consumption.
