Chlorostyrenes in fish and sediment samples from the river Elbe

Chlorinated styrenes were identified in fish (bream) and sediment samples from the river Elbe. Four hexachlorostyrenes, four heptachlorostyrenes (concentrations in fish 1-10 ng/g wet weight) and octachlorostyrene (10-45 ng/g wet weight) were analysed. The gas chromatographic retention times and the electron impact (EI) mass spectra of the respective hepta- and hexachloro congeners found in the environment as well as those of some synthesised compounds are presented and discussed. The comparison of the chromatograms from the samples in the upper part of the river with those from the estuary revealed a possible difference in the pattern of chlorostyrenes.

Syntheses and Properties of Hexa- and Heptachlorostyrenes with Fully Chlorinated Aromatic Nuclei

All six possible hexa- and heptachlorostyrenes with fully chlorinated aromatic nuclei have been synthesized.Their ultraviolet and infrared spectra are discussed, fragmentation in the mass spectrometer described and from the 1H and 13C NMR spectra all para
