Description of key information

Long-term toxicity to invertebrates: 21-d NOEC: ≥4.9 μg/l (measured; highest concentration tested)

Key value for chemical safety assessment

Additional information

A 21-day EC50 of >4.9 μg/L and NOEC of ≥4.9 μg/L (measured, highest concentration tested) have been determined for the effects of the test substance on adult mortality, reproduction and growth of Daphnia magna. In view of the use of flow-through test conditions it is likely that the test organisms were exposed primarily to the parent substance.
