[Investigation on spatial distribution of chloronaphthalenes in flounder Platychtis flesus from the gulf of Gdansk].
Flounders from the three different and relatively distant sites in the Gulf of Gdańsk were collected in august and october 1992 and analysed to investigate a potential differences in concentration and composition of chloronaphthalenes. The method of PCNs measurement was capillary gas chromatography and high resolution mass spectrometry (HRGC/HRMS) after a nondestructive extraction and cleanup step via dialysis with polyethylene membrane and than HPLC preseparation on a activated carbon column. Chloronaphthalenes were separated and quantified on RTx-5 capillary column using an electron impact (EI) mode and selective ion recording (SIR). All samples contained detectable concentrations of many tetra-, penta- and heksachloronaphthalenes, and the total PCNs concentration ranged from 1700 to 3900 pg/gwet weight. A substantial difference in pattern and concentration of PCNs residues in flounders between some of the sampling sites were found.
