Distribution of organochlorine residues between different fractions of sediments and between different planktonic compartments in the Scheldt estuary and the Belgian coastal zone
Delbeke, K.; Bossicart, M.; Joiris, C.; Bogaert, M.; Vanthomme, R. (1989). Distribution of organochlorine residues between different fractions of sediments and between different planktonic compartments in the Scheldt estuary and the Belgian coastal zone, in: Pichot, G. (Ed.) Progress in Belgian Oceanographic Research 1989: proceedings of the North Sea Symposium held in Ghent, 14 February 1989. pp. 393-412
PCB levels in sediments (bulk <63um), suspended matter and zooplankton from the Belgian continental shelf and Scheldt estuary are evaluated in relation to their organic carbon content, lipid content and for sediments also particle size distributions. Geographical and seasonal variations are discussed. A discussion is given on the PCB accumulation mechanics, considering passive (direct) contamination routes (absorption-partitioning) and for zooplankton also indirect contamination through food.
