The concentration of an odor in air that can be detected by a human being; i.e., in the case of sulfides emitted from a Kraft pulping process, an observer can smell these compounds at and above the odor threshold, a concentration of about one part in 109 parts of air. 4, record 1, English, - odour%20threshold
Record number: 1, Textual support number: 2 DEF
(in water pollution) The point at which, after successive dilutions with odorless water, the odor of a water sample can just be detected. The threshold odor is expressed quantitatively by the number of times the sample is diluted with odorless water. 5, record 1, English, - odour%20threshold

[...] les problèmes d'odeurs résultent de mélanges complexes de produits divers et l'on ne peut définir objectivement le véritable seuil olfactif. [...] la méthode ASTM D1391-57 utilise un groupe de 6 ou 8 expérimentateurs que l'on soumet à des dilutions croissantes (concentrations décroissantes) du polluant dans de l'air frais, jusqu'à ce que 50 % des membres déclarent ne plus rien déceler. La concentration correspondante est appelée «odeur minimum identifiable» (OMI ou MIO). Il existe une échelle d'intensité (Voir OII : «Odor intensity index»). 7, record 1, French, - seuil%20olfactif
