RESIDUI DI POLICLOROBIFENILI (PCBs)NEL TESSUTO MUSCOLARE DI DUE SPECIE BENTONICHE: VALUTAZIONE DEL RISCHIO PER IL CONSUMATORE

Polychlorinated biphenyl (PCBs) residues in the muscle tissue of Mugil cephalus and Mullus surmuletus have been determined in order to evaluate the risk for humans, resulting from the consumption of these marine species. Contamination levels were 1210 μg/kg lipid wt for M. cephalus and 252 μg/kg lipid wt for M. surmuletus. Isomer-specific analysis revealed a profile dominated by hexa- and pentachlorobiphenyls. The dietary intake was below to 8 pg TEQs/kg body weight/week recently set by European Commission. To educate the consumer to chose fish with low lipid content and of little size may constitute a valid tool to reduce the exposure risk to these contaminants
