Description of key information
EC50 (EU method C3) > 100 mg/L
Key value for chemical safety assessment
Additional information
Toxicity to aquatic algae Scenedesmus subspicatus was assessed according to EU Method C.3 (Algal Inhibition test).
Scenedesmus subspicata were exposed under static conditions to the substance at nominal concentrations of 1.23, 3.7, 11, 33 and 100 mg test substance/L in freshwater.
The test was performed with 3 vessels per concentration and 6 vessels per control. For each concentration, cell densities were recorded at 24-hours internals
The EC50 for growth inhibition (72h-EC50) was greater than 100 mg/L and NOEC = 100 mg/L.
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.
