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
