Additional information
Thiebaud (2000) is a GLP-compliant, 48 hour freshwater, static test on Daphnia magna, following OECD guideline 202. The results have been based on regression analysis of nominal concentrations. The validity criteria were met and the study is considered reliable and suitable for use for this endpoint.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
