Odor concentration refers to an odor's pervasiveness. To measure odor sensation, an odor is diluted to a detection or recognition threshold. The detection threshold is the concentration of an odor in air when 50% of a population can distinguish between the odorous sample and an odor-free reference sample.
Articles relating to odor, caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive by their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor.
The Lady and the Unicorn, a Flemish tapestry depicting the sense of smell, 1484–1500. Musée national du Moyen Âge, Paris.. Early scientific study of the sense of smell includes the extensive doctoral dissertation of Eleanor Gamble, published in 1898, which compared olfactory to other stimulus modalities, and implied that smell had a lower intensity discrimination.

Articles related to the sense of smell, the special sense through which smells (or odors) are perceived. [1] The sense of smell has many functions, including detecting hazards, and pheromones , and plays a role in taste .
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
The new generations of dynamic dilution olfactometers quantify odors using a panel [5] and can allow different complementary techniques: odor concentration and odor threshold determination, odor suprathreshold determination with comparison to a reference gas, hedonic scale assessment to determine the degree of appreciation, evaluation of the relative intensity of odors, and allow training and ...
