BASIS FOR CALCULATION OF BCF
- Result based on calculated logKow of: -3.69
WoE 3: no data available - Key result
- Type:
- BCF
- Value:
- 3 dimensionless
- Remarks on result:
- other: WoE 2: BCF value of test chemical was estimated using a logKow and a regression-derived equation.
- Key result
- Remarks on result:
- other: WoE 3: Although BCF value of test chemical was not known, but it was reported to be non-bioaccumulative in aquatic organisms.
- Validity criteria fulfilled:
- not specified
- Conclusions:
- On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the BCF value of the test chemical can be expected to be 3 dimensionless. Thus, as this value does not exceed the bioconcentration threshold of 2000 indicating that the test chemical is not expected to bioaccumulate in the food chain.
- Executive summary:
Data available for its read across chemicals has been reviewed to determine the bioaccumulation potential of the test chemical. The studies are as mentioned below:
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 -3.69 and a regression-derived equation. The estimated BCF (bioaccumulation factor) valueof test chemical was evaluated to be 3 dimensionless, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical was considered to be non-accumulative in aquatic organisms.
In an another study, test chemical was reported to be non-bioaccumulative in aquatic organisms.
On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the BCF value of the test chemical can be expected to be 3 dimensionless. Thus, as this value does not exceed the bioconcentration threshold of 2000 indicating that the test chemical is not expected to bioaccumulate in the food chain.
Reference
WoE 2: According to a classification scheme, the BCF value of test chemical suggests the potential for bioconcentration in aquatic organisms is low.
WoE 3: Test chemical was reported to be non-bioaccumulative.
