Materials and methods

Principles of method if other than guideline:
Calculated with BCF Program v. 3.00 of EPI-Suite software. The estimation methodology is based on the chemical structure of an organic compound and its log octanol-water partition coefficient (Kow). Depending on chemical structure, structural correction factors are applied.
GLP compliance:
no
