Chemical and toxicological profiles were assessed in surface sediments (fraction <63??m) from the southern North Sea. In extracts of freeze-dried samples, polybrominated biphenyl (PBB), Irgarol 1051 and phthalate concentrations were below the respective detection limits (except di(2-ethylhexyl)phthalate, which was between 170 and 3300??gkg^???1 dry weight (dw)). Hexabromocyclododecane (HBCD) concentrations were between 0.8 and 6.9??gkg^???1dw, with highest concentrations at river mouths. Polybrominated diphenylethers (PBDE) concentrations were 0.4???0.6??gkg^???1dw, decabromodiphenylether (BDE209) 1???32??gkg^???1dw. The ratio BDE209/PCB153 was used as a tracer for recent emissions, and pointed towards a BDE209 source in the Western Scheldt???s upper estuary. PCBs and PAHs were between 0.19???4.7 and 2.6???200??gkg^???1dw respectively and generally had highest concentrations at near-shore locations and river mouths.
