Description of key information

One algae test has been performed, the EC50 for inhibition of specific growth rate was determined to be 420 µg/L and the EC10 for inhibition of specific growt rate was determined to 184 µg/L. The effects are expressed as nominal values because the tests were performed with river water as they were intended to be used in an evaluation of the environmental risks based on the Bulk approach.

Key value for chemical safety assessment

EC50 for freshwater algae:
420 µg/L
EC10 or NOEC for freshwater algae:
184 µg/L
