Abstract

The concentrations of polychlorinated biphenyls (PCBs) were determined in fish species from Bulgarian Black Sea coast. It had selected three of the most popular fish species in our country - european sprat (Spr. Sprathus Sullinig), Black Sea goby (Neogobius Melanostomu) and Mediterranean horse mackerel - scad (Trachurus Mediterraneus). The fish samples were collected from the region of Varna in year 2003 - 2005 and the edible tissues of the fish species were investigated. The fourteen congeners of PCB were analyzed including the set of 7 indicators PCBs (IUPAC ¹ 28, 52, 101, 118, 138, 153, 180) with Gas Chromatography Mass Spectroscopy method. PCBs were found in all investigated samples. European sprat showed the highest total level of PCBs (187.9 - 220.1 ng/g fat) compared to the other species - goby (66.3 - 192.2 ng/g fat) and horse mackerel (14.7 - 208.2 ng/g fat). The highest level of PCBs was found in year 2005. Our study illustrated that the concentration level of PCBs in analyzed samples was lower compared with those recommended by different European in sti tu tions.
