Abstract: Following the preceding reports, three field surveys were performed to get information about malodor in the atmosphere around a kraft-paper mill over the period from July 1987 to Feb. 1988; the odorant concentration and the intensity as well as concentration of odor were measured chromatographically and olfactorily in the same manners as those so far employed. The finding are : (1) In virtue of the development in the odor source control, the atmosphere has taken a favorable drive; nearly 50% of the odorant concentrations have fallen below the detection limit (0.5ppb), the odor intensities have remained lower than step 2 (the third class in the 6-point system; lightly perceptible) and most of the odor concentrations have ranged from 20 to 30 ou, the rest standing less than 10 ou. To an appendix, a list (Table 4) was made of some of the data in the preceding and presents reports, and, based on it, the relations of observed odor intensity versus calculated one (Fig. 1), of odor concentration versus odor intensity (Fig. 2) and of odorant concentration versus odor concentration (Fig. 3) were discussed from various points of view. Further, the surface concentrations of methyl sulfide at two downwind sites (Table 2) were calculated by the use of an atmospheric diffusion equation and the results were compared with those found (Table 8).
