Description of key information
Bioaccumulation: aquatic/sediment
BCFBAF model (v3.01) of Estimation Programs Interface (EPI Suite, 2017) prediction program was used to predict the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 1887 L/kg whole body w.w (at 25 deg C) which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
Additional information
Bioaccumulation: aquatic/sediment
Various predicted data for the target compound were reviewed for the bioaccumulation end point which are summarized as below:
BCFBAF model (v3.01) of Estimation Programs Interface (EPI Suite, 2017) prediction program was used to predict the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 1887 L/kg whole body w.w (at 25 deg C) which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
Bioaccumulation test was conducted for estimating the bioconcentration factor (BCF) of test chemical. The estimated bioconcentration factor (BCF) of test chemical was estimated to be 1974.74 at pH 5.5 and 7.4, respectively.
From CompTox Chemistry Dashboard using OPERA (OPEn (quantitative) structure-activity Relationship Application) V1.02 model in which calculation based on PaDEL descriptors (calculate molecular descriptors and fingerprints of chemical) the bioaccumulation i.e BCF for test substance was estimated to be 69.7 dimensionless . The predicted BCF result based on the 5 OECD principles. Thus based on the result it is concluded that the test substance is non-bioaccumulative in nature.
In a supporting study, the bioaccumulation study was conducted in fish for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation factor (BCF) value was calculated using an estimated log Kow of 2.25 and a regression derived equation. The BCF (bioaccumulation factor) value of test chemical was determined to be 14 dimensionless, which does not exceed the bioconcentration threshold of 2000, indicating that the chemical can be considered to be non-accumulative in aquatic organisms.
The overall results were supported by the bioaccumulation study conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation factor (BCF) value was calculated using an estimated log Kow of 4.39 and a regression derived equation. The BCF (bioaccumulation factor) value of test chemical was determined to be 1300 dimensionless.
On the basis of above results for test chemical, it can be concluded that the BCF value of test substance ranges from 69.7 –1974.74 which does not exceed the bioconcentration threshold of 2000, indicating that the chemical is 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).
