Odor threshold is the minimum concentration of a substance at which a majority of test subjects can detect and identify the characteristic odor of a substance. While odor thresholds can serve as useful warning properties, they must be used cautiously because olfactory perception varies among individuals.
An odor threshold is used to help determine the air quality in a given work site and potential risk to an individual. Odor threshold factors will vary upon location and potential types of exposures.
