Description of key information
Activated sludge was exposed to diphenyl cresyl phosphate in a 3 hour
respiration inhibition study acording to OECD 209 (Kanne, 1987). The 3 -hour EC50 was reported to be >10000 mg/L (the highest concentration tested), the corresponding NOEC was 10000 mg/L.
Key value for chemical safety assessment
Additional information
Activated sludge was exposed to diphenyl cresyl phosphate in a 3 hour respiration inhibition study acording to OECD 209 (Kanne, 1987). The 3-hour EC50 was reported to be >10000 mg/L (the highest concentration tested), the corresponding NOEC was 10000 mg/L. Therefore, no PNEC can be derived as no effects were seen up to the limit of the water solubility.
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.
