Description of key information

In the key study with Chironomus riparius (Arthur, 2007), the EC50 (28d) value was > 380 mg/kg sediment dw, NOEC (28d) value was 52 mg/kg sediment dw.

Key value for chemical safety assessment

EC50 or LC50 for freshwater sediment:
380 mg/kg sediment dw
EC10, LC10 or NOEC for freshwater sediment:
52 mg/kg sediment dw

Additional information
