Following the European Water Framework Directive (2000/60/EC), the authors proposed, in a previous contribution, a Marine Biotic Coefficient (BC) to establish the ecological quality of soft-bottom benthos within European estuarine and coastal environments. The present study examines the application of the BC to the Atlantic (North Sea; Bay of Biscay; South of Spain) and Mediterranean (Spain and Greece) European coasts. The investigation assesses also the usefulness of the BC, in relation to different impact sources (e.g. drilling cuts with ester-based mud, submarine outfalls, heavy metals, industrial and mining wastes, jetties and sewerage works). The results obtained are consistent with those obtained using several methods and parameters, such as richness, diversity, evenness, Abundance-Biomass comparison plots and univariate and multivariate statistical analyses. The BC values provide a simple and clearly defined way to establish the ecological quality of soft-bottom benthos, complementary to the above mentioned methods.
遵循《欧洲水框架指令》（2000/60/EC），作者在之前的一篇论文中提出了海洋生物系数（BC），以确定欧洲河口和沿海环境中软底底栖生物的生态质量。本研究考察了BC在欧洲大西洋沿岸（北海、比斯开湾、西班牙南部）和地中海沿岸（西班牙和希腊）的应用情况。该调查还评估了BC对于不同影响源（如酯基泥浆钻屑、海底排污口、重金属、工业和采矿废弃物、码头及污水处理工程）的适用性。所得结果与使用多种方法和参数（如丰富度、多样性、均匀度、丰度-生物量比较图以及单变量和多变量统计分析）所获结果一致。BC值提供了一种简单且明确界定的方式来确定软底底栖生物的生态质量，是对上述方法的补充。
