Additional information

Conclusion on classification

The substance is not readily biodegradable and is classified for the environment with H412, P273. The lowest acute ecotoxicity value is an ErC50 (72h) of 18.6 mg/l in and algal growth inhibition study. Long-term fish and Daphnia studies are available with a fish NOEC of 0.64 mg/l. The PNEC is 0.0128mg/l based on the long-term fish NOEC using and assessment factor of 50.
