EC number: 200-769-4
CAS number: 71-91-0
Bioaccumulation: aquatic / sediment
BCFBAF model of Estimation Programs
Interface (2017) 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) which does not
exceed the bio concentration threshold of 2000, indicating that the test
chemical is not expected to bioaccumulate in the food chain.
Various predicted data of the test
chemical were reviewed for the bioaccumulation end point which are
summarized as below:
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 14 dimensionless . The
predicted BCF result based on the 5 OECD principles.
On the basis of above results for test
chemical(from modelling databases,2017), it can be concluded that the
BCF value of test chemical ranges from 3.162 to 14, 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 inaccordance with column 2 of Annex IX of
the REACH regulation,testing for this endpointis scientifically not
necessary and does not need to be conducted since the test chemical has
a low potential for bioaccumulation based on logKow ≤ 3.
