Description of key information
A significant accumulation in organisms is not expected.
Key value for chemical safety assessment
- BCF (aquatic species):
- 60.97 dimensionless
Additional information
No experimental data on the bioaccumulation behavior of the test substance are currently available. Hence, the bioaccumulation potential of the test compound was investigated using three scientifically acceptable calculation models:
A calculation using CATALOGIC v.5.11.2, BCF base-line model v2.05 was conducted with the structure of the test item in order to estimate the bioaccumulation potential (BASF SE, 2013). This model calculates the BCF implicating the measured log Kow value and the water solubility of the test substance. Furthermore, the influence of mitigating factors like ionization of the molecule, water solubility, size and metabolism are also considered by the model. Taking into account these mitigating factors the BCF is reduced to approx. 2.35, mainly due to metabolism and molecule size.
In a second calculation the calculation model T.E.S.T., provided by the US EPA, was applied (v4.1). This model predicts a bioaccumulation factor of 2.99 (log BAF of 0.48) for the test compound.
For the third calculation the BCFBAF v.3.01 of EPISuite v3.20 was used. The calculation revealed a BCF value of 60.97.
Based on these data, the test compound is not considered to significantly accumulate in organisms.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
