| The Bremerhaven Workshop required chemical data to help interpret the biological findings. Polychlorobiphenyls, organochlorine pesticides, polycyclic aromatic hydrocarbons, total hydrocarbons and trace metals were determined in sediments, dab liver and benthic invertebrates collected at stations along the German Bight and drilling site transects. In this paper, the chemical data are presented and reviewed. |

| During the Bremerhaven Workshop an improved, fast and easy method for the determination of ethoxyresorufin-O-deethylase (EROD) activity in dab Limanda limanda liver was tested. The improvement involved the use of a 12500 x g supernatant instead of the microsomal fraction, thus omitting the need for long ultra-centrifugations which cannot be carried out aboard a research vessel. EROD activities in the 12 500 x g supernatant and in the microsomal suspension were well correlated. Despite its disadvantages of lower specific EROD activity, higher minimum detection limit and higher analytical variance, the 12 500 x g supernatant was used for further analysis. EROD activity in dab liver showed a spatial trend corresponding to a pollution gradient in the German... |
