Key value for chemical safety assessment
- EC50 for microorganisms:
- 320 mg/L
Additional information
The toxicity of the test substance to microorganisms was determined in a GLP-compliant study according to OECD Guideline 209 (CG, 1994). In this study, activated sludge from a local communal sewage treatment plant was exposed to test substance concentrations of 0, 10, 32, 100 and 320 mg/L. No inhibitory effects on respiration were noted up to the highest concentration tested. Based on these findings, the 3 -h IC50 was determined at >320 mg/L (nominal concentration).
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.
