EC10/EC50 (3 h) > 100 mg/L (OECD 209, 2010)
Key value for chemical safety assessment
Additional information
One study is available investigating the toxicity of 4,4',4''-methylidynetrianiline (EC No. 208-952-0) to activated sludge microorganisms according to OECD 209, 2010 (Spoo-Klöppel, 2015). Activated sludge from a sewage treatment plant treating predominantly domestic sewage was used as inoculum. This study was performed as a limit test with a concentration of 100 mg/L and the respiration rate was measured after 3 h. No inhibition of respiration was recorded compared to the control resulting in an EC10 (3 h) > 100 mg/L and an EC50 (3 h) > 100 mg/L. No inhibition of the biodegradation process in sewage treatment plants caused by the test substance is anticipated.
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.
