Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when the substance introduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The toxicity on microorganisms was tested according to OECD 209 (RCC 1996). The respiration rate of aerobic waste water bacteria was not inhibited when exposed to the test article concentrations of 10, 20, 32 and 50 mg/L. At 100 mg/L, the respiration rate was very slightly inhibited by 1.8 %. Based on these results, the EC50 (30 minutes) was determined to be >100 mg/L.
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.
