Muscle tissue of bluefin tuna (Thunnus thynnus) was analysed for PCBs to ascertain whether the concentrations exceeded the levels fixed by the European Commission and whether this fish was suitable for human consumption. PCB concentrations were comprised between 96 and 6571 ng/g l. w. (mean: 764 ng/g l.w.). Isomer-specific analysis revealed a profile dominated by hexa- (65.4%) and pentachlorobiphenyls (18.0%), followed by hepta- (15.4%) and tetrachlorobiphenyls (1.2%). The dietary intake was below the limit of 14 pg TEQs/kg body weight/week set by European Commission. The results obtained are not to underestimate, considering that the daily intake do not include other food which might also pass these contaminants to man.
