Description of key information
Halophosphate was tested in a fresh water algal growth inhibition test (OECD 201). No reduction of growth rate was recorded at a 0.45 μm filtered solution prepared at a loading rate of 100 mg/L after 72 hours of exposure.
Key value for chemical safety assessment
Additional information
Halophosphate was tested in a fresh water algal growth inhibition test (OECD 201). Under the conditions of the study with Pseudokirchneriella subcapitata, no reduction of growth rate was recorded at a 0.45 μm filtered solution prepared at a loading rate of 100 mg/L after 72 hours of exposure. The EC50 for growth rate reduction exceeded the concentration present in a 0.45 μm filtered solution prepared at a loading rate of 100 mg/L, which was considered the maximum soluble concentration in test medium. The NOEC equaled the maximum soluble concentration in test medium.
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.
