Description of key information

Bioaccumulation: aquatic / sediment

From BCFBAF (v3.00) model of EPI suite Program, the estimated bio concentration factor (BCF) for 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate is 1657 L/kg whole body w.w which does not exceed the bio concentration threshold of 2000. Thus it is concluded that 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate is not expected to bioaccumulate in the food chain.

Additional information

Bioaccumulation: aquatic / sediment

Three results including different predicted data from validated models for bioaccumulation (BCF) endpoint of target chemical 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate (Cas no. 2345-26-8) were summarized as follows:

 

First prediction done using BCFBAF (v3.00) model indicate the estimated bio concentration factor (BCF) for 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate is 1657 L/kg wet-wt which does not exceed the bioconcentration threshold of 2000. Thus it is concluded that 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate is not expected to bio accumulate in the aquatic environment.

 

Other prediction database PBT profiler indicate the Bioaccumulation factor (BCF) for test substance 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was estimated to be 1700 L/kg wet-wt at 25 deg.C.

 

Whereas Chemspider - ACD/PhysChem Suite estimates the Bioconcentration factor (BCF) for target chemical 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate as 1485.09 at pH 5.5 and 7.4 at temperature 25 deg.C.

 

Thus based on the above information for bioaccumulation endpoint, it can be concluded that the test substance 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate (Cas no. 2345-26-8) is expected to be non Bioaccumulative in aquatic environment.
