Description of key information

In this study, the test item was found to inhibit the growth of the freshwater green alga Desmodesmus subspicatus after 72 hours with the following effect values (based on nominal test item concentrations): The EC50-values with 95% confidence intervals for inhibition of growth rate (ErC50) after 72 hours wase > 177 . The NOEC-values for inhibition of both growth rate and yield after 72 hours were 70.8 mg/L.

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
70.8 mg/L
