The advent of the Water Framework Directive and the introduction of the Water Act will place the focus of the assessment of aquatic systems on the quality of surface water. This raises the question of the extent to which aquatic sediments act as a source of pollution due to the release of substances. This study examines whether substances are released from aquatic sediments to the water column by means of diffusive transport, and the degree to which this occurs. It also considers what routine or specialist methods are available to measure this subsequent release of substances. Three very different locations (IJmuiden, the Afferdensche and Deestsche Waarden, and the Ghent-Terneuzen Canal) were sampled. A range of measuring techniques were used, and experiments were conducted to quantify emission fluxes of organic compounds (PAHs, PCBs), heavy metals and nutrients
