Additional information

Aquatic compartment PNECs are derived from LC50 value for Algae (NOEC is 18.0mg/L) which is the lowest short-term result from representatives of three taxonomic groups (fish, crustaceans, algae).

PNECsed and PNECsoilwere calculated from equilibrium partitioning.

The followed equation for freshwater and marine compartment was used:

PNECsed=(0.783 +0.0217xKoc)xPNECwater and for calculation of the PNECsoil=(0.174 +0.0104xKoc)xPNECwater.

The PNEC STP was calculated using NOEC value and assessment factor 10 was used for PNEC derivation.)

Conclusion on classification

The substance is not classified for environmental toxicity according to CLP Regulation (EC) no. 1272/2008.
