[Chlordanes in blubbere harbour porpoises (Phocoena phocoena) from Gulf of Gdańsk]

ABSTRACT

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 frans-nonachlor (37%) as a most abundant compound, and followed by heptachlor epoxide (15%), ris-chlordane (14%), cu-nonachlor (14%), oxychlordane (11%), MC6 (3%), MC5 (2%), fra/is-chlordane, MC7, U82 and MC4 (<1%).
