| Abstract: | PCDDs, PCDFs and some related aromatic compounds were determined isomer specifically in sediments from the river Rhine and its tributaries, in order to study sources and environmental fate of these compounds. Additionally, waste water effluents from industries that unintentionally might coproduce PCDDs or PCDFs were analyzed. In all sediments and in some waste water effluents these compounds could be detected. Variations of the isomeric patterns of the PCDFs enabled a distinct industrial area, that was associated with PCB contamination to be identified. The contamination of sediments and organisms from the Dutch river Rhine delta with these compounds mainly could be attributed to the transboundary pollution of the river Rhine. |
