Abstract: In our recent paper, we have published an equation relating the odor concentration of a compound odor to its material concentration given as the sum of those of the ingredients, and now, making certain assumptions, we have derived second ones, eq. (6) and (8), of simplified form. Employing these two and further, eqs. (7) and (14), we have examined some of characteristics of a compound odor. The results are as under : (1) Regarding the relation between odor concentration and odor intensity, it was found, as shown in Table 2,that odor intensities of 3 and 3.5 correspond respectively to odor concentrations of 30 and 70. (2) When the decrease in material concentration changes in a manner of a geometrical progression, the fall in odor intensity proceeds in an arithmetic progression; thus it can be seen that if the concentration be reduced by half, the intensity should remain practically unaltered. Additionally, we applied eqs. (7) and (14) to the data of waste combustor facilities, and it was discovered that there is a definite discrepancy between the observed and calculated values; the observed values are, in most cases, too high within a factor of several decades, this being possibly due to the presence of yet unidentified ingredients in the odor investigated.
