Additional information

PNECs have been derived for freshwater, marine water, intermittent releases and the STP using the available endpoints. The PNECs were calculated using endpoints obtained using freshwater aquatic species and STP microorganisms. PNEC values for sediment were derived by the equilibrium partitioning method (EPM). No PNECS were calculated for air, or secondary poisoning as they are deemed to be unnecessary. The PNECs are as follows:

PNEC freshwater = 0.0044 mg/L

PNEC marine water = 0.00044 mg/L

PNEC intermittent = 0.044 mg/L

PNEC STP = 1mg/L

PNEC sediment (freshwater) = 0.144 mg/kg dw

PNEC sediment (marine) = 0.014 mg/kg dw

PNEC soil = 0.026 mg/kg dw

Conclusion on classification

The lowest acute L(E)C50 is 4.4 mg/L, and as such the substance does not attract classification for acute aquatic toxicity. However, as the substance is not rapidly degradable under CLP guidelines, and the lowest acute L(E)C50 is between 1mg/L and 10 mg/L, the substance is classified as toxic to aquatics, chronic category 2.
