Description of key information

GLP study reporting EL50 (48 h) > 1000 mg/L based on growth rate (OECD 201)
Non-GLP study reporting EC50 (day 2 to day 4) as > 10mL/L

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L

Additional information

Methodological deficiencies render a non-GLP study unreliable. However, the key study was conducted in accordance with OECD methods and found the maximum reduction in culture growth compared to controls was 16 %. THis value is deemed reliable.
