ErC10 = 58.1 mg/L (BASF AG, 1993)
NOErC = 25 mg/L (BASF AG, 1993)
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 58.1 mg/L
Additional information
In a 72 hour acute toxicity study, cultures of green algae (Scenedesmus subspicatus, CHODAT SAG 86.81) were exposed to the test substance at nominal concentrations of 0 (control), 0.78, 1.56, 3.13, 6.25, 12.5, 25, 50 and 100 mg/L under static conditions in accordance with EU method C.3. NOEC, EC10 and EC50 values based on growth rate were 25 mg/L, 58.1 mg/L and above 100 mg/L. No compound related phytotoxic effects were observed during the study.
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.
