Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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 (aquatic species):
2.508 L/kg ww

Additional information

The BCF for 2-methylpyridine was estimated as 2.508 L/kg wet weight (log BCF = 0.399), and indicates that this compound has a low potential for bioaccumulation. The Japan National Institute of Technology and Evaluation reported a steady-state BCF of 0.79, with the statement that the chemical substance was determined "to be not highly bioaccumulative", thus confirming the low potential for bioaccumulation.
