Additional information

PNEC aquatic is based on the lowest predicted EC50 value for individual components present in the "unsaturated monoterpene hydrocarbon" group, which is a daphnia EC50 of 0.215 mg/L (see aquatic toxicity endpoint summary for details). The terrestrial and soil PNECs have been derived from PNECaquatic using the equilibrium partitioning method. PNEC STP is based on information content from a ready biodegradation test for the single substance, D-Limonene, which is representative of the "unsaturated monoterpene hydrocarbon" assessment entity. Absence of microbial toxicity can be inferred from biodegradation studies, e.g. if a compound degrades well in a ready biodegradability test this concentration can be used as a NOEC value. D-limonene was found to be readily biodegradable at a test concentration of 10mg/L.

Conclusion on classification

Not relevant for assessment entity. The conclusion for the classification of the whole substance is provided in the aquatic toxicity endpoint summary.
