The aim of this study is to develop a new method for classification of marine benthic quality according to the European Union Water Framework Directive. Tolerance values to environmental disturbance were determined in an objective analysis for benthic species along the Swedish west coast by using 4676 samples from 257 stations. Based on a combination of the species tolerance values, abundance and diversity, a benthic quality index (BQI) was calculated for the assessment of environmental status at a particular station. The qualification of BQI was evaluated in relation to known spatial and temporal gradients of disturbance.

    • "The BQI is one of the most widely used multimetric indices for macrofauna status assessment (Rosenberg et al., 2004; Fleischer and Zettler, 2009; Leonardsson et al., 2009). Although designed for application in marine areas, it is also considered to be suitable for different environments provided that the assigned species' tolerance/sensitivity values are based on individual data sets and "

    ABSTRACT: The European Marine Strategy Framework Directive requires EU Member States to prepare national strategies and manage their seas to achieve good environmental status (GES) by 2020. There are many multimetric indices proposed as indicators of the ecological quality of the benthic environment. Their functionality and utility are extensively discussed in the literature. Different frameworks are suggested for comparative assessments of indicators with no agreement on a standardized way of selecting the most appropriate one. In the current study, we apply signal detection theory (SDT) to evaluate the specificity and sensitivity of the Benthic Quality Index (BQI), its response to the eutrophication pressure, and its performance under the effects of estuarine water outflow. The BQI showed acceptable response to total nitrogen, total phosphorus and chlorophyll-a concentrations in the study area. Based on the results, we suggest using SDT for setting GES thresholds in a standardized way. This aids a robust assessment of the environmental status and supports differentiation between the quality classes.

    • "). In addition, a series of biotic indices used in the context of the WFD was calculated: BQI (Rosenberg et al., 2004) as modified in Leonardsson et al.

    ABSTRACT: Biological and geochemical variables in the water column and sediments were monitored along a transect of a mussel farm located in a transitional environment in Maliakos Gulf, a semi-enclosed gulf in eastern Mediterranean. Analyses of water, sediment and macrofauna samples were used to calculate ecological status indicators in the context of the European Water Framework Directive. The water column ecological status was "Poor" or "Bad" showing little change with distance from the farm, but the ecological status of the benthic communities was found to be "Good," although there were quantitative changes in macrofaunal indices with distance from the farm.

    • "For certain pressures a signal in LHT of a species may be observed before the abundance changes. To support the WFD, there is an extensive literature in the interpretation of the good status (Rosenberg et al., 2004; Muxika et al., 2007; Borja and Dauer, 2008; Borja et al., 2009b), including intercalibration in coastal waters (Borja et al., 2007, 2009a; Pinto et al., 2009). Some of the indicators (AMBI, M-AMBI) have been widely used (e.g. "
