Theoretical odor concentration
Theoretical odor concentration (Cod, OT) was also calculated to
compare with the results of the triangle odor bag test. Another purpose
of this is to screen significant odorous compounds in the
landfill.
Eqs. (1) and (2) show that for each odorous compound the estimation
of its theoretical odor concentration is based on the ratio of
chemical concentration to the odor threshold concentration values.

where Cod is the specific theoretical odor concentration of compound
i, Ci is the chemical concentration of the compound i, OTi is
the odor threshold concentration of compound i, and n is the number
of compounds in the mixture. Cod, OT is regarded as theoretical
odor concentration of the sample by sum up the theoretical odor
