Description of key information

In a static dose-response test, the growth of the freshwater green algae Pseudokirchneriella subcapitata was assessed. The 72-hour ErL50 value was calculated to be 105 mg test item/L and the 72-hour EyL50 was calculated to be 31 mg test item/L. The 72-hour ErL10 and EyL10 were determined to be 29 mg/L and 6.1 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
105 mg/L
EC10 or NOEC for freshwater algae:
29 mg/L
