ResumoAbstract Concentrations of polychlorinated biphenyls (PCBs) were determinated in the muscle tissues of mullets ( Liza aurata ) caught from two coastal marine areas in Tunis bay, “Raoued” and “Rades”. Twenty congeners were detected in all the fish samples analyzed, among which were 4 congeners recommended by the European Union for assessing pollution and 4 “dioxin-like” congeners. Residue levels of total PCBs ranged from 45 to 194 ng/g wet wt in the mullet from “Rades” and from 43 to 65 ng/g w wt in specimens from “Raoued”. Hexachlorobiphenyls were predominant in fishes caught from both “Raoued” and “Rades” areas, accounting for 43% and 40%, respectively. The individual PCB profiles were dominated by congeners 153 in mullet from “Raoued” and PCB 200 in fishes from “Rades”. The levels of TEQs of “dioxin-like” congeners were 3.4 pg/g w wt for fishes from “Raoued” and 2.5 pg/g w wt for specimens from “Rades”.
