Description of key information

The results presented represent NOECs

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater fish:
26 mg/L
EC10, LC10 or NOEC for marine water fish:
2.3 mg/L

Additional information

For the freshwater fish (Pimephales promelas) the endpoint is based on a reduction in weight relative to the control at the concentration of 48 mg a.i./L (the concentration above the NOEC).

For the saltwater fish (Cyprinonidon variegatus) no effects occured at the highest concentration tested (2.3 mg a.i./L)
