Concentrations of CB188 relative to assessment criteria

The figure shows concentrations of CB188 relative to the assessment criteria BAC (Backgound Assessment Concentration) and EQS (Environmental Quality Standard as given in the Water Framework Directive). For instance, a point at '4x EQS' indicates a site where the observed concentration was four (4) times the EQS limit. The points have been spread in the x direction in order to avoid too much overlap.

Additional information

Concentrations of CB-118 in mussels and oysters are relative to environmental thresholds (3). Each point represents a location (station). The green points under the yellow line are locations with concentrations under BAC; the yellow points are over BAC but under EQS (Environmental Quality Standard), while the red points are locations with concentrations over EQS. The inset (upper left) shows time trends (change per decade) by the MSFD region over the most recently available 10-year period (meta-analysis of trends for each location). Significant decreases are shown in green, while insignificant time trends are shown in black. Regions not included in the time trend graph did not have enough data to enable trend analysis.
