Fish (herring, cod, eelpout, round goby, flounder, perch, lamprey, pikeperch, sand eel and lesser sand eel) caught in the Gulf of Gdansk in 1992 contained the residues of penta- (PCBz) and hexachlorobenzene (HCBz) in concentrations from 0.09 to 0.75 and from 0.36 to 3.7 ng/g wet weight (3.3-14 and 6.5-41 ng/g lipid weight), respectively. Both compounds were identified and quantified using capillary gas chromatography and low resolution mass spectrometry (HRGC/LRMS) after a non-destructive extraction and clean-up step with a semipermeable polyethylene membrane and further fractionation on the Florisil column. A higher HCBz/PCBz ratio indicated in some species of fish caught near the city of Gdynia when compared to the specimens caught close to the city of Gdansk indicated the existence of a slight local source of pollution with HCBz in the area of the seaport of the city of Gdynia.

An attempt has been made to review pollution of the Baltic fish and fishery products by hexachlorobenzene (HCBz) and to estimate daily intake of HCBz and pentachlorobenzene (PCBz) with marine and freshwater fishes and fishery products in Poland. The calculated arithmetic mean weighed concentrations of HCBz in muscle tissue of the Baltic fish are 22 ng/g wet weight in herring in 1973-1985 (n = 3115) and 4.3 ng/g in 1986-1992 (n = 371); 14 ng/g in sprat in 1971-1985 (n = 939); 6.4 ng/g in salmon in 1976-1982 (n = 151); 14 ngig in eel in 1981-1982 (n = 480); 200 ng/g m cod-liver in 1973-1978 (n = 72) and 85 ng/g in 1979-1990 (n = 918); 0.65 ng/g in cod in 1981-1992 (n = 527); 2.2 ng/g in flatfishes in 1974-1992 (n = 396); 0.96 ng/g in perches in 1983-1992 (n = 70) and 2.8 ng/g in other fish species in 1981-1992 (n = 192). The intake of HCBz has been assessed for 60 to 92 ng/person/day in the years 1973-1985 and from 45 to 56 ng/person/day (mean 52 ng) in 1989-1996, while of PCBz for 7.8 to 11 ng/person/day (mean 9.4 ng) in 1989-1996.
