Description of key information
72 h, EC50>104 mg/L, Desmodesmus subspicatus, measured
72 h, NOEC =104 mg/L, Desmodesmus subspicatus, measured
Key value for chemical safety assessment
Additional information
A 72 h EC50 value of >104 mg/L has been determined for the effects of the test substance on growth rate and biomass of the freshwater algae Desmodesmus subspicatus. In the same study a 72 h NOEC value of =104 mg/L has been determined. The results are based on geometric mean measured concentration due to rapid loss of test substance from test medium.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
