Additional information
Conclusion on classification
Three acute endpoints for three different trophic levels are available. The lowest EC50 is found for Daphnia and is 51.9 mg/L. Three chronic endpoints are available, the chronic NOEC for fish is 8.3 mg/L.
The substance is not readily biodegradable, but has a low log Kow (log kow < 3) and all chronic NOEC values are greater than 1 mg/L.
Under Regulation (EU) No 286/2011 (2nd ATP to CLP) neither acute nor chronic environmental classification is needed.
