The Aquatic Impact Indicator Database (AiiDA) groups together the 7 most important ecotoxicity databases and is based on more than 570 000 ecotoxicological tests results for more than 3600 species belonging to 30 phyla. This global ecotoxicity database is used to automatically calculate different ecotoxicological endpoints and their uncertainties. The database itself has two levels, first the tests results that are presented in an homogeneous format with transparent documentation; second the indicators per substances that are calculated on the tests.

Several indicators are provided such as the the HC50 (Hazardous concentration for 50% of species also called avlogEC50) which is commonly used in Life Cycle Impact Assessment (LCA), the HC5 (Hazardous concentration for 5% of species) which is used in the statistical approach in risk assessment and the PNEC (Predicted No Effect Concentration) which is described in depth in the Technical Guidance Document (TGD) from the European Commission. Aiida covers data on 7500 molecules from which 5400 are covered with data on 3 phyla or more. The calculated endpoints are available in the interactive platform which provides the results and the traceability of all the calculation steps of the endpoints. This traceability assure the consistency of the aquatic indicators. The comparison of the substances and the calculation of the Species Sensitivity and Phyla Sensitivity Distributions are provided to the user. Aiida is edited by Jerome Payet.
