Description of key information

L579 was tested in a fresh water algal growth inhibition test (OECD 201). No reduction of growth rate was recorded in a filtered solution prepared at a loading rate of 100 mg/l after 72 hours of exposure.

Key value for chemical safety assessment

Additional information

L579 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 in a 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 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.
