[Compounds from the chlordane group in adipose tissue of harbour seals from the Gulf of Gdansk].

The composition and the concentration of chlordanes were shown in blubber of harbour porpoises collected from the Gulf of Gdańsk, Baltic Sea, in 1991-1992. Chlordanes were determined using capillary gas chromatography and low resolution mass spectrometry (HRGC/LRMS). The range of CHLs concentration in blubber was between 420-1000 ng/g wet weight (470-1300 ng/g lipid weight). The composition of CHLs residues was similar in males and females, with trans-nonachlor (37%) as a most abundant compound, and followed by heptachlor epoxide (15%), cis-chlordane (14%), cis-nonachlor (14%), oxychlordane (11%), MC6 (3%), MC5 (2%), trans-chlordane, MC7, U82 and MC4 (< 1%).
