Hedonics of odors and odor descriptors
Open accessAbstract
The hedonic tone (pleasantness-unpleasantness) of an air pollution odor depends on its character and influences how annoying the odor may be. In the context of air pollution, both unpleasant and pleasant odors may become objectionable, while this is less likely for hedonically neutral odors. A profile of an odor consists of a list of odor descriptors and ratings of the applicabilities of each of the descriptors to the odor being characterized. The working hypothesis was that each of the descriptors can be assigned its own hedonic connotation (tone) from very pleasant, through neutral, to the very unpleasant. The hedonic tones of the descriptors could then be combined with the descriptor applicability percentages over the entire profile, producing a profile-derived hedonic index. The data that were used were profiles of odors and the hedonic ratings of the same odors made directly upon smelling these odors, obtained independently of the study.

Estimated hedonic values of odor descriptors reported in the survey were significantly higher than those of descriptors not reported, supporting odor-memory congruency.
“We observed that the estimated hedonic values of the descriptors identified in our survey were significantly higher than those of the descriptors not reported (one-tailed t test, t(98.9) = 2.01, p = 0.024, d = 0.35; Fig 1D; S1 Data).”

The Hedonic Tones of Descriptors and APCA NOTE-BOOK sections report hedonic ratings and mean values for odor descriptors, which could provide the values used in the citing authors’ analysis. They do not report the citing authors’ survey, a significant difference between reported and unreported descriptors, or an odor-memory congruency finding; the citing sentence presents that comparison as its own observation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
