Description of key information
BPS-MAE was considered to have had no biologically significant inhibitory effect on the respiration rate of activated sludge at any of the concentrations employed in the test. The EC20, EC50 and EC80 of the test substance could not, therefore, be calculated but these must be greater than 100 mg/I, the highest level tested.
The three-hour EC50 for 3,5-DCP (9.0 mg/I) fulfilled the validity criterion relating to sensitivity to inhibition (acceptable EC50 range 5 to 30 mg/I), and that relating to the respiration rates in the control (variation not greater than 15%) was also satisfied.
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.
