Description of key information

The 72-h EC50 value based on growth rate and yield were both determined to be > 100 mg/L. The 72-h EC10 value based on growth rate and yield were determined to be > 100 mg/L, too. 

Key value for chemical safety assessment

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

Additional information

The 72-h algal growth inhibition test with Pseudokirchneriella subcapitata was conducted according to EU method C.3, OECD no. 201 guideline and EPA OPPTS guideline 850.5400. The 72-h EC50 value based on growth rate and yield were both determined to be > 100 mg/L. The 72-h EC10 value based on growth rate and yield were determined to be > 100 mg/L, too. The average measured concentration of the test item in the test solution was 90.78 % of the nominal at the start and 88.60 % of the nominal at the end of the test, therefore nominal concentrations were used.
