Assessment of contaminant status of indicators of biological effects using CHASE+, Dec. 2019

This data set presents the resulting assessment grid (based on the EEA reference grid) with the classification of chemical status of the transitional, coastal and marine waters in the context of the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD), providing a mapping of contamination 'problem areas' and 'non-problem areas' based on measurements of biological effects. This classification has been performed using the CHASE+ tool, with classifications of the of contaminant status of indicators of biological effects. The status is evaluated in five classes, where NPAhigh and NPAgood are recognised as ‘non-problem areas’ and PAmoderate, PApoor and PAbad are recognised as ‘problem areas’. Monitoring biological effects is restricted to a few indicators (e.g. imposex) and data coverage is currently limited. Biological effects have thus been addressed in only 134 assessment units, mostly in the Baltic Sea, the North Sea and the North-East Atlantic Ocean. This data set underpins the findings and cartographic representations published in the EEA report “Contaminants in Europe’s seas” (No 25/2018). See the mentioned report for further information.本数据集呈现了基于欧洲环境署（European Environment Agency, EEA）参考网格构建的最终评估网格，该网格结合《水框架指令》（Water Framework Directive, WFD）与《海洋战略框架指令》（Marine Strategy Framework Directive, MSFD）的框架要求，对过渡水域、近岸海域及远洋海域的化学状态进行分类，并基于生物效应测量结果绘制了污染“问题区域”与“非问题区域”的空间分布图。本次分类工作依托CHASE+工具完成，针对生物效应指标的污染物状态开展分级评估。评估共设五个等级，其中NPAhigh与NPAgood被界定为“非问题区域”，PAmoderate、PApoor及PAbad则被归为“问题区域”。当前生物效应监测仅限定于少数指标（如性畸变imposex），且数据覆盖范围有限。因此，仅在134个评估单元中开展了生物效应相关分析，这些单元大多分布于波罗的海、北海及东北大西洋海域。本数据集为欧洲环境署（EEA）发布的报告《欧洲海域污染物》（第25/2018号）中的研究结果与制图成果提供了核心支撑。如需了解更多详细信息，请参阅上述报告。
