Description of key information
Bioaccumulation: aquatic / sediment
The bioaccumulation study in fish was conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation BCF value was calculated using a log Kow of 2.81 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 33 dimensionless, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical was considered to be non-accumulative in aquatic organisms.
Additional information
Bioaccumulation: aquatic / sediment
Data from various sources for the test chemical were reviewed for the bioaccumulation end point which are summarized as below:
The bioaccumulation study in fish was conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation BCF value was calculated using a log Kow of 2.81 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 33 dimensionless, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical was considered to be non-accumulative in aquatic organisms.
Above data further supported by the data obtained from secondary source. The bioaccumulation study on aquatic organisms was conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation factor (BCF) value was calculated using a log Kow of 2.81 and an equation. The estimated BCF value of the test chemical was determined to be 29.09 dimensionless, which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical was considered to be non-bioaccumulative in aquatic organisms.
Similar BCFBAF model of Estimation Programs Interface was used to predict the bioconcentration factor (BCF value) of the test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 33.19 L/kg whole body w.w (at 25 °C) which does not exceed the bio concentration threshold of 2000, indicating that the test chemical was not expected to bioaccumulate in the food chain.
On the basis of above results for test chemical, it can be concluded that the BCF value of test chemical was ranges from 29.09 to 33.19,which does not exceeds the bioconcentration threshold of 2000, indicating that the test chemical was 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).
