Description of key information
Bioaccumulation: aquatic / sediment
BCFBAF model 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 3.162 L/kg whole body w.w (at 25°C) which does not exceed the bio concentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
Additional information
Bioaccumulation: aquatic / sediment
Predicted data of the test chemical and various supporting weight of evidence study for its structurally similar read across substance were reviewed for the bioaccumulation end point which are summarized as below:
In aprediction done using theBCFBAF Programof 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 3.162 L/kg whole body w.w (at 25°C).
In a supporting weight of evidence study from authoritative database (2017) for the test chemical,he bioaccumulation study was conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation factor (BCF) value was calculated using a logKow of -2.74 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 3.0 dimensionless.
For the test chemical, the bioaccumulation study was conducted for determining the BCF (bioaccumulation factor) value of test chemical (HSDB, 2017). Although BCF value of test chemical was not known, but ionic character of test chemical indicates that the chemical is non-bioaccumulative in aquatic organisms.
On the basis of above results of the test chemical, it can be concluded that the BCF value of test chemical was evaluated to be 3.0,which does not exceed the bioconcentration threshold of 2000, indicating that the test chemicalis not expected to bioaccumulate in the food chain.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
