Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The individual estimation program BCFBAF and/or its underlying predictive methods and equations have been described in numerous journal articles in peer-reviewed technical journals.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The BCFBAF Program is an update and expansion of the previous BCFWIN Program that was part of the EPI Suite version 3.20. The BCFBAF program estimates BCF of an organic compound using the compound's log octanol-water partition coefficient (Kow). The original estimation methodology used by the original BCFWIN program is described in a document prepared for the U.S. Environmental Protection Agency (Meylan et al., 1997). The BCFBAF Program updates the BCF estimation methodology of the BCFWIN program by using an updated and better evaluated BCF database for selecting training and validation datasets. The exact same regression methodology used to derive the original BCFWIN method was used to derive the BCFBAF method for estimating BCF.

- Details on estimation of bioconcentration:
- The BCFBAF method classifies a compound as either ionic or non-ionic. Ionic compounds include carboxylic acids, sulfonic acids and salts of sulfonic acids, and charged nitrogen compounds (nitrogen with a +5 valence such as quaternary ammonium compounds). All other compounds are classified as non-ionic.
Non-ionic compounds are predicted by the following relationships:
log BCF = 0.6598 log Kow - 0.333 + Sum F(i) (log Kow 1.0 to 7.0)
log BCF = -0.49 log Kow + 7.554 + Sum F(i) (log Kow > 7.0)
log BCF = 0.50 (log Kow < 1.0) (where Sum F(i) is the summation of structural correction factors)
Log Kow used by BCF estimates: 3.3 (experimental value). - Key result
- Type:
- BCF
- Value:
- 645.6 L/kg
- Basis:
- other: wet weight
- Calculation basis:
- other: BCFBAF equation
- Remarks on result:
- other: Conc.in environment / dose:no data
- Details on kinetic parameters:
- not applicable
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The BCFBAF program estimated an aquatic BCF of 645.6 L/kg wwt based on an experimentally derived logKow = 5.1
Reference
Description of key information
The key value for bioaccumulation is derived via Log Kow-based estimate using the BCFBAF module of EpiSuite.
Key value for chemical safety assessment
- BCF (aquatic species):
- 645.6 L/kg ww
Additional information
Due to the lack of data on bioaccumulation, the BCFBAF program estimated an aquatic BCF of 645.6 L/kg wwt based on an experimentally derived logKow = 5.1
