Abstract
Chlorinated hydrocarbons have been determined in sediments and breams (Abramis brama) from different locations along the river Elbe, starting from the border to the Czech Republic down-stream up to Cumlosen (river km 470), near the frontier of the former German Democratic Republic. High levels of hexachlorobenzene (HCB) have been found in sediments. HCB, DDT-metabolites and octachlorostyrene (OCS) have been the most dominant compounds in bream, especially fish from eastern sampling sites have been heavily contaminated. Furthermore, sediments from 1991–1993 have been analysed to determine polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F). The CHC-burden of the river Elbe declines downstream, whereas the PCDD/F-content increases in that direction.
