Description of key information
The determination of the inhibition of oxygen consumption by activated sludge was assessed according to EEC Directive 88/302/EEC, ISO Standard 8192 and OECD Test Guideline 209. The EC50 (180 mins) was > 1000 mg/L (nominal).
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
Additional information
The determination of the inhibition of oxygen consumption by activated sludge was assessed according to EEC Directive 88/302/EEC, ISO Standard 8192 and OECD Test Guideline 209. The EC50 (180 mins) was > 1000 mg/L (nominal). The EC20 in the test was > 100 mg/L. Disturbances in the biodegradation process of activated sludge are not to be expected, if the test substance is correctly introduced into adapted wastewater treatment plants at low concentrations.
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.
