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 changes in the respiration rate of activated sludge in presence of the test substance was investigated in a guideline study according to ISO 8192, with activated sludge as inoculum. At test termination after 30 minutes effect concentrations > 700 mg/L (nominal) were determined [BASF AG 1986].
Additionally, oxygen consumption test which was conducted according to ROBRA (DIN 38412, part 27) are available for the toxicity assessment. The bacteria Pseudomonas putida was exposed to different test concentrations of the test substance [BASF AG 1986]. After an exposure period of 16 h an EC10 of 6287 mg/L (nominal) was determined.
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.
