Description of key information
The inhibition of the degradation acitivity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The toxicity to microorganisms was tested in a study conducated according to OECD guideline 209 under consideration of GLP. 62.5, 125, 250, 500 and 1000 mg/L test substance were used as test concentrations. After an exposure time of 3h no inhibition of oxygen consumption in the activated sludge was observed. Therefore, the EC10, EC20, EC50 and EC80 were determined to be greater than 1000 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.
