Therefore sediments were sampled in July 2002 and September 2002 at 5 stations in the greater Hamburg area. Sediments and elutriates of the sediments were analysed for toxicology (algal growth inhibition test, elutriate; bioluminescence bioassay, elutriate and bacterial contact test assay, sediment), ARGE-Elbe chemical compounds (Pb, Cr, Cd, Cu, Zn, Hg, As; EPA-PAH, PCB, HCH, HCB, DDT) and additionally screened in detail for organic componds via GC-MS. The data of this small program provide informations about the influence of the flood on the Hamburg harbor system. Additionally, 2 suspended matter samples of the water quality assurance net of Hamburg were screened for further compounds not included in the analysis program and for comparison relative to the sediment samples.
