Description of key information

Long-term toxicity to Daphnia: NOEC = 25 mg/L

Key value for chemical safety assessment

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

Additional information

A 21-day chronic study has been undertaken in Dapnia magna. Under the conditions of the study the NOEC for survival and reproduction of daphnids exposed to a mean measured concentration of 25 mg/l were comparable to the survival & reproduction of daphnids in the control group.Another chronic study in Dapnia magna has been reported in the literature, a NOEC for survival and reproduction of daphnids exposed to a nominal concentration of 13 mg/L being described.
