Abstract
Sediment samples are pre‐treated with acid, mixed with silica and Soxhlet‐extracted with benzene/hexane. Humic substances and elemental sulfur are removed by passing the extract through a Chromatographie column containing basic alumina on which sodium sulfite and sodium hydroxide were adsorbed. After silica fractionation the concentrations of PAH's, PCB's and chlorinated pesticides are determined gas chromatographically. Recovery experiments with added standards gave recoveries of between 90% and 102%. Samples from two different European estuaries were analyzed with this new desulfuration/fractionation procedure: Rotterdam harbour sediment (Netherlands) and river Elbe estuarine sediments (Western Germany).This publication has 4 references indexed in Scilit:
