ORGANOCHLORINE PESTICIDES (OCPs) AND POLYCHLORINATED BIPHENYLS (PCBs) IN MURAENA HELENA FROM THE ADRIATIC SEA NEAR DUBROVNIK, CROATIA
The work demonstrates why Moray eels are good bioindicator organisms for the local studies of bioaccumulation or biomagnifi cations. Morays were caught in the East Adriatic Sea near Dubrovnik in what is believed to be an unpolluted area. Not a single animal was recorded to be free of OCPs or PCBs. Regardless of the season, minimally 5 to 11 pollutants were detected in each fi sh in the summer and 5 to 9 in the winter period. Out of these, at least 1 to 5 were PCB congeners in the summer and 3 to 4 congeners in the winter caught fi sh. Levels of bioaccumulated p-DDT were similar to those in other biota caught from the Italian side of central and southern Adriatic or same as average values for the Mediterranean biota. Other OCPs had lower (but detectable) levels than in the rest of the Adriatic or Mediterranean (endrine > ppDDE > heptachloreepoxide >heptachlore > aldrine > lindane > βHCH > δHCH > endrine aldehyde). During winter season, 20 % higher concentrations of endrine were present in fi sh. Aldrine was detected only in the summer caught fi sh while δHCH and endrine aldehyde were detected only in the winter caught fi sh. Other OCPs were present in both seasons in different proportions. We detected PCB congeners 77, 105, 114, 118, 125, 156, 169 which is again fewer than the usual average in the fi sh of the Adriatic and Mediterranean. PCB 105 and 169 were the only two congeners found in the same proportion in caught fi sh regardless of the season. A congener 169, which is considered to be of a particular hazardous potential, was detected in all analysed fi sh regardless of the season.
