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
Data on toxicity to microorganisms are available in the ECB IUCLID (2000) for 2-nitrophenol. The EC50 after 3 h using activated sludge of a predominantly domestic sewage in an OECD 209 guideline study was determined to be 400 mg/L. Hence, 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.
