Additional information

PNECs were derived for freshwater, saltwater, sediment and soil using the HC5 model plus statistical extrapolation or equilibrium partitioning calculations.

Conclusion on classification

The lowest reported acute result is a 48 hour LC50 for Daphnia of 3.84 mg/L. There is an OECD 301 biodegradation study which indicates that this substance is not readily biodegradable; with no NOEC values available this would result in a classification of Chronic Category 2 with the hazard statement 'Toxic to aquatic life with long lasting effects'.
