- PBT status:
- the substance is not PBT / vPvB
- Justification:
Eucalyptus oil is considered as a readily biodegradable mixture, with a log octanol-water partition coefficient comprised between 2.84 and 4.42 and a worst case BCF value at 852.9 L/kg wet-wt, which is a conservative BCF value for the mixture. Therefore, Eucalyptus oil does not meet the criterion for persistence (P) and bioaccumulation (B). For the T criterion, based on individual acute toxicities of the major constituents, the L(E) C50 values for Eucalyptus oil were estimated to be 0.90 mg/L for fish, 1.02 mg/L for aquatic invertebrates and 1.64 mg/L for algae, and the NOEC value for Eucalyptus oil was estimated to be 0.88 mg/L for algae (based on growth rate). However, to prove that this constituent approach was considered as a worst case and finally not realistic, two experimental acute fish studies were performed for two worst case typical mixtures of Eucalyptus oil, showing 96h-LL50 of 18mg/L and 42 mg/L for both Eucalyptus crude oil and Eucalyptus oil globulus respectively. Therefore, the key EC50 value used to derive PNEC is 1.02 mg/L for aquatic invertebrates. As this value is greater than 0.1 mg/L, Eucalyptus oil is presumably not T.
In conclusion, Eucalyptus oil could not be considered as a PBT or vPvB substance.
- Likely routes of exposure:
Not relevant as substance not PBT nor vPvB.
