Description of key information
Acutely harmful to aquatic algae.
EC50 (72h) = 97 mg/L and EC10 (72) = 15.4 mg/L (nominal) for growth rate of Desmodesmus subspicatus (OECD 201)
Key value for chemical safety assessment
Additional information
In a GLP guideline study following OECD 201 green algae (Desmodesmus subspicatus) were exposed for 72 hours to
the test item [Eurofins, 2013]. Based on the low water solubility of the test substance the aquatic toxicity was determined using saturated stock solutions. The respective concentrations were determined in a pretest. The 72-h EC50 for growth rate inhibition was 97 mg/L and the EC10 (72h) was 15.4 mg/L based on loading rate.
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.
