Description of key information
The inhibition of the degradation activity of activated sludge is not anitcipated when introduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The effect of the substance on the respriration rate of activated sludge was determined in a study following OECD guideline 209. The respiration rate was monitored for 30 minutes. Based on the nominal test substance concentrations an EC20 of 1000 mg/l (EC50 >1000 mg/l) was determined (BASF AG 1998).
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.
