The individual species phase biodegradation rate constant can be adjusted for
temperature as:

k bij ( T ) = k bij (20) Q Tij (T−20)/10 (4.90)

10” temperature correction factor for biodegradation of species i,
in phase j and T is the ambient temperature in segment [

where Q Tij is “Q −

C].
The temperature correction factors represent the increase in the biodegradation
rate constants resulting from a 10

°

° C temperature increase. Values for Q T ij in the

range of 1.5 to 2 are common.
