Fishes have been used to characterize pristine aquatic environments. In samples from a lake in the Tyrolian Alps (arctic char) and Northwest Ireland (pike), the Caspian Sea (sturgeonevruga), the North Atlantic (salmon), the North Pacific (salmon) an the Antarctic Ocean at South Georgia (antarctic cod) hexachlorobenzene and polychlorinated camphene (PCC, toxaphene) have been found. Samples are extracted by n-hexane/acetone (2 + 1), following a dimethylformamide/hexane clean-up of the lipid matrix. Adsorption chromatography on Florisil (1.25% water content) allows the elution of hexachlorobenzene, 4,4'-DDE and the polychlorobiphenyls (PCB) with n-hexane, while the mixture n-hexane/diethyl ether (90 + 10) will elute the polychlorocamphenes (PCC) together with the hexachlorocyclohexane (BHC) isomers and the DDT group. Identification of the PCC has been done by matching their retention indices measured by high resolution ECD glass capillary gas chromatography using the n-alkyl-trichloroacetates as references and technical toxaphene together with a slightly dehydrochlorinated product as authentic samples. The PCC content of the samples from the lakes in the European Alps and Northwest-Ireland, the North Pacific and the Antarctic Ocean was 125, 240, 285 and 68 ng of PCC per g of extractable lipids, respectively. The samples from the Caspian Sea and the North Atlantic had 1625 and 3500 ng of PCC per g of extractable lipids, respectively. All samples but the one from the Antarctic Ocean (liver) were spawn. Besides hexachlorobenzene and the PCC all samples contained polychlorobiphenyls (PCB), the alpha, beta and gamma-isomers of hexachlorocyclohexane, the compounds of the DDT-group and many other ECD-detectable not yet identified compounds.
