The ratio between mean concentrations of hazardous substances in the blue mussel and values for Background/Reference concentrations (BRC-values) or Ecotoxicological Assessment Criteria (EAC- values) for these substances has been used to present the development on a comparable scale



Additional information

The BRC/ EAC-values have no legal significance and are only related to risks for marine ecosystems and not to human health risks (from consumption of mussels). The ratio is called Ecological Reference Index (ERI). BRC/ EAC-values have an upper and lower limit; the upper value has been used to calculate the ERI. ERI = 1 for the upper limits of the BRC/ EAC-range.
