Description of key information
The calculation of BCFs via BCFWIN v2.15 for the C8-C18 fatty acid derivates yielded values in the range between 3 (C8 fatty acid derivate) and 71 (C10 – C18 and C18 unsaturated fatty acids derivates). Based on the calculated BCFs a low potential for bioaccumulation is to be expected AAPBs.
Key value for chemical safety assessment
- BCF (aquatic species):
- 71 L/kg ww
Additional information
No experimental results for bioaccumulation with AAPBs are available. Considering the ready biodegradability, demonstrating the ability of organisms to metabolize AAPB, a relevant bioaccumulation potential of AAPB is not expected. This expectation is also supported by a modelling approach performed by Meylan et al. (1999). To develop a model on bioaccumulation, Meylan et al. (1999) collected measured BCF (sources: AQUIRE, CITI, HSDB and EFDB), log Kow (sources: MEDCHEM 'star list', Sangster's LOGKOW DATABANK or sources referenced in the EFDB or KOWWIN estimates), and pKa values for ionizing substances (sources: SRC's PHYSPROP database, compilation of Perrin and Serjeant and Dempsey and reference handbooks such as Handbook of Organic Chemistry, the Handbook of Chemistry and Physics and other sources cited in the EFDB or calculated using pKalc 3.1 software or SPARC). The database of 694 compounds with recommended BCF values contained 84 compounds defined as ionic, including carboxylic acids, sulfonic acids, and quaternary ammonium compounds. Based on the correlation of measured log BCF values and log Kow, log BCF values were deduced. The results were used to develop the computer program BCFWIN. Therefore, BCFWIN v2.15 was used to calculate the BCF values for the C8-C18 derivates of AAPB. The calculation yielded values in the range between 3 (C8 fatty acid derivate) and 71 (C10 – C18 and C18 unsaturated fatty acid derivates). Based on the calculated BCFs a low potential for bioaccumulation is to be expected for AAPBs. Measured BCFs are not available.
