Endis-Risks is a four year project carried out by one Dutch and five Belgian research groups (see partners) in the framework of the SPSD-II research action of the Belgian Federal Science Policy Office. The Endis-Risks project aims to assess the distribution and the possible effects of endocrine disrupting substances in the Scheldt estuary. Priority substances, their physico-chemical distribution (speciation within the different compartments: sediment, water, suspended solids), their concentration in biota (mysid shrimp and gobies) and their geographic distribution will be assessed.

The valorisation of the Endis-Risks project will result in a thorough, integrated and multi-disciplinary description of the current status of the Scheldt estuary in relation to the issue of endocrine disruption. This study will result in a fundamental, ecotoxicological risk assessment of endocrine disrupting substances in the Scheldt estuary.

The major research objectives within the project are:

  • Analyses of endocrine disruptors in water, suspended solids, sediment and biota (mysids, gobies);
  • In vitro evaluation of the estrogenic and androgenic potential of samples of water, suspended solids and sediment;
  • Ecotoxicological and in situ evaluation of the effects on the resident mysid populations (short, intermediate and long-term);
  • Risk assessment of endocrine disruptors in the Scheldt estuary.


  • The ENDIS-RISKS project has come to an end. Therefore, this website will no longer be adjusted.
  • The Final Report of ENDIS-RISKS project can be downloaded here
