[DDT and it metabolites in fish in the Gulf of Gdańsk].
The residues of DDT and its metabolites (DDTs; p,p'-DDT, o,p'-DDT, p,p'-DDD, o,p'-DDD, p,p'-DDE, o,p'-DDE i p,p'-DDMU) has been determined in ten species of edible fish caught in the Gulf of Gdańsk in 1992. The method of measurement was capillary gas chromatography and low resolution mass spectrometry (HRGC/LRMS) after a nondestructive extraction and clean-up step with a further fractionation of the extract on Florisil column. All fish examined contained detectable residues of DDTs, and the concentrations ranged from 28 to 310 ng/g wet weight. o,p'-DDT accounted from 0.4 to 2.5% to DDTs content. The residue concentration of DDTs in herring (110 ng/g wet weight and 1100 ng/g lipid weight) in 1992 was threefold lower than in the years 1979-1983 and fourteen fold lower than in 1969-1973.
