Table 2.

Contaminant concentrations in blue mussel and eelpout from the North Sea/ESB sampling site NS 1 (Lower Saxony Wadden Sea; FAO/ICES Division 27.4.b). White fields: D9 relevant contaminants; light blue shading: consideration of breathing water (measured concentration × 3); light green shading: additional contaminants not yet required for D9 assessment; concentrations for metals are given in mg kg⁻¹, those for PCDD/Fs + dl-PCBs as pg g⁻¹ WHO-TEQ, and all others in μg kg⁻¹ (all wet weight based)

n number of annual pool samples, n.s. not significant

^#Calculation based on linear trend analysis

^aMaximum level for human consumption (Regulation (EC) No. 1881/2006 and amendments)

^bSum of benzo[a]pyrene, benzo[a]anthracene, benzo[b,j,k]fluoranthene and chrysene + triphenylene

^cWet weight Environmental Assessment Concentration (EAC) for mussels calculated from the dry weight EAC of 12 μg kg⁻¹ and a mean water content of 90.6% in blue mussels from NS 1 during the sampling period
