Abstract: Several researches have shown that some polychlorinated biphenyl congeners and organochlorine pesticides degrade slowly in the environment and build up in the food chain, causing a wide range of possible adverse effects to humans. Marine organisms are an excellent indicator for pollution in aquatic ecosystems, where trace contaminants are difficult to be analyzed directly. The aim of the study was to determine concentrations of persistent organochlorine compounds in some marine species from the Black Sea, Bulgaria. Concentrations of polychlorinated biphenyls (PCBs), DDT and its metabolites were determined in rapana (Rapana venosa), shrimp (Crangon crangon) and mussels (Mytilus Galloprovincialis) collected from the Black Sea in summer 2011. Determination of PCB congeners, DDT and its metabolites DDE and DDD was carried out by gas chromatography coupled to mass spectrometry after clean-up of the fatty extracts. The levels of organochlorine pollutants in rapana and mussels were found in the order DDTs > PCBs. Among the DDTs, essentially only the metabolites p, p’-DDE and p, p’-DDD were found. The sum of DDT and its metabolites was determined from 1.78 to 3.27 ng/g wet weight (in rapana and mussels, respectively) and PCBs concentrations were found below 0.12 ng/g ww. The levels of persistent organochlorine pollutants in mussels, rapana and shrimp were found lower compared to those in seafood from other studies.
