Description of key information

A PNEC sediment is derived using the EP method and results in a PNEC sediment of 8.15 mg/kg dw. A PNEC sediment is based on all long-term aquatic toxicity information from 3 trophic levels. This value is more reliable and more conservative then deriving a PNEC sediment from testing with sediment organisms, because the concentrations in the aquatic compartment can be maintained while this is more complex in a sediment toxicity test.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater sediment:
8.15 mg/kg sediment dw
