To answer the requirement of the European Commission's Water Framework Directive (WFD) for biological-effects endpoints to classify the ecological health of aquatic ecosystems, we propose the biomarker response index (BRI). The BRI, based on a suite of biomarkers at different levels of biological response at the individual level, provides an integrated relative measure of the general health status of coastal invertebrates. Using the BRI, the health of mussels (Mytilus edulis) from 10 estuaries classified by the Environment Agency of England and Wales under the WFD was compared. Eight sites were healthier than predicted and two showed a similar health status to that of the predicted point-source pollution risk classification. Results indicate that the BRI offers a potential measure of organism health that can be used in monitoring under the WFD as an additional aid to reduce uncertainty in defining risk classification and to provide better evidence of existing impact.
为满足欧盟委员会水框架指令（WFD）对生物效应终点的要求，以对水生生态系统的生态健康进行分类，我们提出了生物标志物反应指数（BRI）。BRI基于个体水平上不同生物反应层次的一系列生物标志物，提供了沿海无脊椎动物总体健康状况的综合相对度量。利用BRI，对英格兰和威尔士环境局根据WFD分类的10个河口的贻贝（紫贻贝）健康状况进行了比较。8个地点的健康状况好于预期，2个地点的健康状况与预测的点源污染风险分类相似。结果表明，BRI提供了一种潜在的生物体健康度量方法，可用于WFD下的监测，作为减少定义风险分类不确定性的额外辅助手段，并为现有影响提供更好的证据。
