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 microbial toxicity of the test substance was studied in a non-GLP guideline study with activated sludge according to OECD 209 (BASF, 1991; Rep. no. 1/91/0407/08/1). The 30min EC20 was determined to be 800 mg/L.
In a non-GLP guideline study with Pseudomonas putida growth inhibition test according to Bringmann-Kühn, German Industrial Standards DIN 38412, part 8, the 17h EC50 was determined to be 66 mg/L (BASF, 1990; report no. 9/1890503).
Based on the available information, 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.
