Topics: Water and marine environment Environment and health

The figure shows concentrations of CB188 relative to the assessment criteria BAC (Background 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.

Metadata

Methodology:: For status, we used the 90% percentile over the 10-year period 2010-2021 to classify concentrations in 'low', 'moderate' and 'high' classes using two threshold values. The lower of the two thresholds was OSPAR's BAC criterion, while the threshold value was the EQS given by the Water Framework Directive. In order to calculate status, we needed at least 1 year (Mediterranean) or 3 years (other areas) of data since 2010.
