Polychlorinated biphenyls (PCBs) and some oranochlorine pesticides were measured in flounder, cod, sole, shrimps and mussels by capillary gaschromatography. PCBs predomiated among the organochlorine residues and represented 75 to 90 % of the global content. The average PCB-concentration in the wet tissue ranged from 39.5 ppb in shrimps to 261.1 ppb in mussels. From the group "DDT and its metabolites" only the derivates p,p'-DDE and p,p'-DDD could be quantified. The different organochlorine pesticides were present in concentrations generally below 5 ppb in wet tissue. From the point of view of public health the organochlorine residues in marine organisms seem to present no risk.
