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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
