[Residues of chlordane in fish in the Gulf of Gdańsk].
Concentrations, composition and spatial variations of the residues of the pesticide Chlordane were determined in several species of fish caught in Gulf of Gdańsk. The residues of Chlordane (cis-i trans-chlordane, cis-i trans-nonachlor, oxychlordane, heptachlor, heptachlor epoxide, MC4, MC5, MC6, MC7, U82 and U83) were found in all fish examined, however, the concentrations noted were low, i.e. from 0.40 to 12 ng/g wet weight. Among the Chlordane constituents and metabolites determined trans-naonachlor, cis-chlordane, oxychlordan, heptachlor epoxide, cis-nonachlor, MC5, MC6 and trans-chlordane were dominated, and MC4, MC7, U82 and U83 were minor compounds. No heptachlor residues were found in fish examined. A small concentrations and specific composition of the residues of Chlordane and its metabolites determined in fish from the Gulf of Gdańsk do indicate on a distant sources of pollution with that pesticide--mainly transported and deposited via the atmosphere.
