Additional information

The basis for the PNECs, except PNECoral, is provided in the 2009 Environment Agency report (UK EA 2009) on the environmental risks for LCCPs. The PNEC oral is based on the same point of departure as the long-term systemic DNEL (23 mg/kg body weight or approximately 300 mg/kg food) used for the C18 -C20 liquid LCCP. The PNEC oral values for C20 -C30 LCCPs will be higher due to higher points of departure, so this value is the most conservative PNECoral for LCCPs.

Conclusion on classification

Based on the lack of effects in environmental organisms at or below the water solubility limit, LCCP are not classified as dangerous to the environment. See supplemental review document provided in Section 13 of the dossier.
