Description of key information
Bioaccumulation: aquatic / sediment
The bioaccumulation study was conducted for estimating the BCF (bioaccumulation factor) value of test chemical (authoritative database, 2017). The bioaccumulation factor (BCF) value was calculated using a logKow of 0.37 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 3.0 dimensionless, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is considered to be non-accumulative in aquatic organisms.
Additional information
Bioaccumulation: aquatic / sediment
Various studies and predicted data of the test chemical were reviewed for the bioaccumulation end point which are summarized as below:
In an experimental key study from authoritative databases (2017), the 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 0.37 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 3.0 dimensionless.
In a prediction done using the BCFBAF program 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 deg C).
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 chemical was estimated to be 4.29 dimensionless . The predicted BCF result based on the 5 OECD principles.
On the basis of above results for target chemical, it can be concluded that the BCF value of test chemicalwas determined to be ranges from 3.0– 4.29, respectively, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
Bioaccumulation endpoint can also be considered for waiver as per in accordance with column 2 of Annex IX of the REACH regulation, testing for this endpoint is scientifically not necessary and does not need to be conducted since the test chemical has a low potential for bioaccumulation based on logKow ≤ 3.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
