Description of key information

The 72-h EL50 valuse expressed in terms of the nominal loading rate WAF of the test substance to Pseudokirchneriella subcapitata were determined to be > 100 mg/L loading rate WAF for growth rate and 76.3 mg/L for yield. The 72-h NOELR (No-observed effect loading rate) was expressed as 58.8 mg/L loading rate WAF for growth inhibtion and yield.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
58.8 mg/L
