Description of key information
A significant inhibition of bacterial respiration was not observed up to and at the highest test concentration of 1000 mg/L tripotassium hexacyanocobaltate in an activated sewage sludge respiration inhibition test according to OECD 209. Therefore, the respective 3-h EC10 and EC50 values were estimated with > 1000 mg/L and the 3-h NOEC (respiration inhibition) with ≥ 1000 mg/L tripotassium hexacyanocobaltate (Simon, 2018). Hence, a hazard for aquatic microorganisms could not be identified for tripotassium hexacyanocobaltate.
Key value for chemical safety assessment
Additional information
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.
