Description of key information

Measured data on bioaccumulation of TNPP are not available. A calculated BCF has been obtained using EpiWin: 3.162 L/kg. However, given TNPP's measured log Kow of 14 (the BCF model used an even higher log Kow - 20), TNPP's large molecular weight and molecule, there are indications that the model calculations overestimate the bioaccumulation potential of the substance.

Regardless, the value is well below the B criterion of 2000 L/kg; indicating that TNPP is not a PBT substance.
