Description of key information
A study designed to determine the effects of test item on the growth of Pseudokirchneriella subcapitata over a 72h period was conducted in accordance with the OECD 201 Test Guideline.
The concentrations of test item causing 50 % and 10% reductions in growth rate were estimated:
72h-ErC50 = 1.6 mg/L
72h-ErC10 = 0.64 mg/L
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 1.6 mg/L
- EC10 or NOEC for freshwater algae:
- 0.64 mg/L
