There are many on-line databases available on the internet today that can be useful when solving Ecological Risk Assessment (EcoRA) issues. Most of these databases provide information on toxicology data, hazardous chemicals, chemical and physical properties, hazard identification, dose-response assessment, bioavailability etc. In general, available internet databases concern on properties of chemical substances, and many of these databases are very well developed and provide extensive and valuable information in this area. The test results here can be often incomparable due to different methodology used to acquire results. The aim of this article is to inform about efforts to provide a tool that can parametrically describe and store information about various ecotoxicological tests and can be used to quickly find relevant tests for given situation and therefore support the decision-making process. The system and its current content is further described here and proposed changes and possible collaboration is outlined.
