Additional information
In an OECD 201 guideline study conducted by RCC in 1996 Desmodesmus subspicatus (reported as Scendesmus subspicatus) was exposed to the test substance for 72 hours. In the static test system the test item concentrations were analytically verified and the EC50 (72 h) based on the growth rate was determined to be 14.5 mg/L and therefore has to be classified as harmful to algae.
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.
