A proprietary ASRIT study is available.
Key value for chemical safety assessment
Additional information
Five concentrations of phosphorus trichloride (1000, 1800, 3200, 5600 and 10000 mg/L) were assessed for their effect on activated sludge by measuring the respiration rate and % inhibition according to ISO 1892. The resulting nominal EC50 value was calculated to be 9450 mg/L. Analytical determination of test substance concentration was not practical due to its rapid reaction with water and subsequent degradation
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.
