| Abstract [eng] |
This study provides the analysis of the macrozoobenthos species sensitivity values and application of Benthic Quality Index (BQI) for the assessment of the south-eastern part of the Baltic Sea. The numerical sensitivity concept and its use in BQI were tested for different depths, macrozoobenthos communities and types of anthropogenic disturbance. The BQI was validated against total nitrogen, total phosphorus and chlorophyll concentrations, and the dynamics of macrozoobenthos sensitivity groups was used to characterise water quality class boundaries for the coastal waters. The specificity and sensitivity of the BQI was assessed using the non-parametric Signal detection theory method and its performance in relation to eutrophication parameters was tested for the open coastal waters and plume of the Curonian Lagoon. Additionally, the detailed recommendations for the coastal water status assessment in the southeastern part of the Baltic Sea were provided. |
