ED-NORTH database

The ED-North database is a database containing the data that where gathered during the SPSD I research project 'Evaluation of possible impacts of endocrine disruptors on the North Sea ecosystem'. This ED-NORTH project aimed at establishing a clear overview of the increasing volume of available scientific literature on endocrine disruption. Specific objectives were: to address the uncertainties presently associated with the issue of environmental endocrine disruption; to specify future research and policy needs; to accomplish these tasks specifically for endocrine modulating activity in the marine environment.

Based on the available scientific literature a list and electronic database of chemicals with (potential) endocrine disruptive activity was developed. This relational database contains information on the hormone disrupting potential, including effects and physico-chemical properties of these chemicals. Chemicals of which enough data was available on the environmental concentrations in the North Sea and the sources and endocrine effects they cause were prioritised. Finally, future research and policy needs were formulated based on these results.

The ED-North database is a MS Access relational database that contains 423 references, 765 chemical compounds and 2355 test cases. A search interface to this database provides the possibility to search on chemical compound, described effect and author. An entire list of compounds can be obtained by leaving the search fields blank.

The database was developed by the Research Group Environmental Toxicology, Laboratory of Environmental Toxicology and Aquatic Ecology, Ghent University, Belgium. For queries about the data, please contact Colin Janssen or Tim Verslycke .
Development of the ED-North database search interface was carried out by Francisco Hernandez of the Flanders Marine Institute.
