Description of key information
The inhibition of the degradation activity of acitvated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The toxic potential of the compound towards activated sludge was investigated in an OECD 209 guideline study under consideration of GLP. The incubation time of the activated sludge was 3 hours, the tested concentration were nominal 1000, 500, 250, 125, 62.5 mg/L. The EC10, EC20, EC50 and EC80 were all above 1000 mg/L. The inhibition of the degradation activity of acitvated sludge is not anticipated when introduced to biological treatment plants 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.
