Description of key information

21-d NOEC(reproduction) in Daphnia magna): 1.1 mg/L (MoE, 1998) 
21-d NOEC(reproduction) in Daphnia magna): 2.6 mg/L (Springborn, 1995)
The geometric mean of the two NOECs is carried forward for the risk assessment: 1.69 mg/L

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
1.69 mg/L

Additional information

For the long-term toxicity to invertebrates two equivalent 21 -d reproduction studies exist with Daphnia magna. Both are reporting similar NOECs: 1.1 mg/L (MoE, 1998) and 2.6 mg/L (Springborn, 1995).
