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.
