Description of key information

Bioaccumulation: aquatic / sediment:

From BCFBAF Program (v3.00) model of EPI suite the estimated bio concentration factor (BCF) for 2-Nonanone is 54.8 L/kg wet-wt which does not exceed the bioconcentration threshold of 2000.Thus it is concluded that 2-Nonanone is not expected to bio accumulate in the food chain.

Additional information

Bioaccumulation: aquatic / sediment:

Four different studies from validated predicted databases for bioaccumulation endpoint of target chemical 2-Nonanone (Cas no. 821-55-6) are summarized as followed:

 

First study from prediction report by BCFBAF Program (v3.00) model which indicate the estimated bio concentration factor (BCF) for 2-Nonanone is 54.8 L/kg wet-wt which does not exceed the bioconcentration threshold of 2000.Thus it is concluded that 2-Nonanone is not expected to bio accumulate in the food chain.

Another predicted database PBT profiler propose the Bioaccumulation factor (BCF) was predicted to be 55 L/kg wet-wt at 25 deg.C for test chemical 2-Nonanone.

And Scifinder database indicate the Bioconcentration factor (BCF) for target chemical 2-Nonanone was predicted to be 115 at pH 1-10 and temperature 25 deg.C. Based on the BCF concentration at all pH range i.e 1 -10 it is concluded that the test chemical 2-Nonanone is non bioaccumulative in nature as it does not exceed the BCF criteria of 2000.

Whereas Chemspider - ACD/PhysChem Suite prediction model indicate the Bioconcentration factor (BCF) for target chemical 2-Nonanone was estimated to be 185.37 at pH 5.5 and 7.4 at temperature 25 deg.C.

All predicted values for bioaccumulation is in the range of 54.8 -185.37 (L/kg or dimensionless) conclude the target chemical 2-Nonanone (Cas no. 821-55-6) is non bioaccumulative in aquatic environment as it does not exceed the BCF criteria of 2000 as per the CLP regulation.
