To address this
issue, we tested model sensitivity to biotransformation by incrementally
increasing the rate constants for biotransformation. This
evaluation will give us information on how values for biotransformation
range that will have a strong impact on model results.
Biotransformation rates of volatile organic compounds are concentration
dependent and are generally considered to follow Michaelis–
Menten kinetics (Filser et al., 2000; Chiu and White, 2006):
