Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
A GLP guideline study according OECD 209 has been conducted (BASF SE 2017). The inhibition of the oxygen consumption has been determined in the Activated Sludge Respiration Inhibition Test using activated sludge from a municipal wastewater treatment plant. After 3 h exposure no effects could be observed up to the highest tested concentration. Therefore, EC10, EC20, EC50 and EC80 were determined to be > 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.
