Description of key information
The bioconcentration factor (BCF) was estimated by BCFBAF v3.00, a model within Estimation Programs Interface Suite™ for Microsoft ® Windows, v4.00. This estimated BCF is useful to evaluate the potential for bioaccumulation in both aquatic and terrestrial habitats.
Key value for chemical safety assessment
- BCF (terrestrial species):
- 2.965 L/kg ww
Additional information
The BCF for 4-methylpyridine was estimated as 2.965 L/kg wet weight (log BCF = 0.472), and indicates that this compound has a low potential for bioaccumulation.
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.
