Tools 4 Environment launches AiiDA v1.0, a world-wide aquatic ecotoxicological database
Since the use of chemicals became widespread, many negative consequences have been observed on man and his environment. Scientists have therefore attempted to identify and quantify the toxicity of substances released into the aquatic environment.
Although the reality and the significance of the ecotoxic impacts of industrial chemicals on rivers have been proven, these impacts are rarely taken into account in the framework of eco-design.
The lack of ecotoxicological data, the difficulty of accessing these data and the complexity of the implementation of calculations and methods for determining the various indicators of aquatic ecotoxicity make the use and the ecological representativeness of these indicators hardly exploitable.
AiiDA (Aquatic Impact Indicator Database), developed by Tools for Environment provides 200 000 unique tests and sourced over 7500 molecules, 3600 species and 45 phyla. This overall database is used to automatically calculate the various indicators of aquatic ecotoxicity and their uncertainties by following the official TGD (Technical Guidance Document). It covers 5400 molecules with ecological representativeness of 3 or more phyla.
The indicators available are:
- HC50 (hazardous concentration 50%)
- HC5 et HC5-95% (Hazardous Concentration 5 %)
The values thus obtained will soon be made available through an interactive internet platform (AiiDA version2) which will allow to keep records of calculations and to trace all the source tests used. The platform will make it possible to draw SSD Species and SSD Phyla curves of various molecules and compare their toxicity levels.
