Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The study was performed accoridng to OECD guideline no. 209 (1984). The EC50(3h) was determined to be > 100 mg/L, based on nominal concentrations. The test compound was added to the water without any suspension aid. No effect on the bacteria was observed.
In a non-GLP guideline study according to OECD 209 performed with a structural analogue, no toxic effects were observed at 100 mg/L in activated sludge. Therefore, the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
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.
