Additional information
Various predicted data for the test chemical and supporting weight of evidence studies for its structurally similar read across substance were reviewed for the bioaccumulation end point which are summarized as below:
In a prediction done using the BCFBAF Program (v3.01) of Estimation Programs Interface was used to predict the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 22.95 L/kg whole body w.w (at 25 deg C).
In an another prediction done by using Bio-concentration Factor module, the Bio-concentration Factor over the entire pH scale (pH 1-14) of the test chemical was estimated to be 40.5, respectively.
In a supporting weight of evidence study from authoritative databases (2017) for the test item,bioaccumulation experiment was conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation factor (BCF) value was calculated using an estimated log Kow of 3.32 and a regression derived equation. The BCF (bioaccumulation factor) value test substance was determined to be 72 dimensionless.
For the test chemical,the bioaccumulation study was conducted in fish for estimating the BCF (bioaccumulation factor) value of test chemical (HSDB, 2017). The bioaccumulation factor (BCF) value was calculated using an estimated log Kow of 2.83 and a regression derived equation. The BCF (bioaccumulation factor) value test substance in fish was determined to be 34 dimensionless.
On the basis of above results for test chemical, it can be concluded that the BCF value of test chemical ranges was evaluated to be upto 72, respectively which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
