PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

The Log Kow for tert-amyl hydroperoxide has been read across from 1,1,3,3-Tetramethylbutyl hydroperoxide and was determined to be 2.9 (this value is supported by a QSAR estimated log octanol/water partition coefficient (KOWWIN and VCClab models) for tert-amyl hydroperoxide: Log Kow = 1.43 +/- 0.48). The test substance should thus have low potential for bioaccumulation, it is not classified as a PBT substance nor vP/vB.
