Abstract Odor emission from livestock production systems is a major nuisance in many rural areas. This study aimed at determining the major airborne chemical compounds responsible for the unpleasant odor perceived in swine facilities during slurry handling, and at proposing predictive models of odor concentration (OC) based on the concentrations of ...

Abstract Models formulated to associate odors and odorants in many industrial and agricultural fields ignore the potential effect of relative humidity on odor perception, and are not validated. This study addresses literature limitations by formulating a model that includes relative humidity and by validating the model.

Data Modulation Technique Using Concentration of Odor Molecules
2018 IEEE SENSORS, 2018This study proposed a novel data modulation technique for digital communication by using a concentration of odor molecules. The information is encapsulated in an odor with controlled concentration levels in accordance with the binary representation of the message by using an olfactory display.

Odorant concentration and receptor potential in olfactory sensory neurons
Biosystems, 1998The first step of olfactory transduction consists of the interaction of odorant molecules with receptor proteins. This interaction can be described either as a single-step reaction (binding only) or as a double-step one (binding and activation). The number of bound or activated receptors is analyzed as a function of the external concentration of ...

Concentration of Odorous Headspace Volatiles
1985Highly volatile odorous compounds were studied by examination of the vapour phase above samples by so-called headspace analysis. The static method was applied to study equilibria as they occur in alcoholic beverages. To obtain detectable amounts of minor components the headspace was enriched.

A general method for estimating threshold concentrations of odorant molecules
Journal of Insect Physiology, 1969Abstract A description is given of a modification of the diffusion model technique that permits relatively rapid estimation of the behavioural threshold concentrations of odorant molecules. The method has been employed in studies of alarm behaviour in ants and is adaptable to a wide variety of laboratory and semi-natural conditions.

Odor-concentration coding in the guinea-pig piriform cortex
Neuroscience, 2005By optical imaging of intrinsic signals, we demonstrated a possible code for odor concentration in the anterior piriform cortex of the guinea-pig. Odor-induced cortical activation, which primarily originated in layer II, appeared in a narrow band beneath the rhinal sulcus over the lateral olfactory tract, corresponding to the dorsal part of the ...

Determination of the Odor Threshold Concentrations of Chlorobrominated Anisoles in Water
Journal of Agricultural and Food Chemistry, 2004Trihalophenols, which are drinking water disinfection byproducts (DBPs) formed by chlorination or chloramination practices, can be biomethylated into trihalogenated anisoles. These latter compounds have traditionally been suspected of causing odor episodes in drinking water around the world.

Journal of Animal Science, 1999
Odor intensity (5,437 observations), determined by human panelists (100 different panelists over the course of the experiment), and a number of chemical odorant concentrations were determined for manure-related samples (326) obtained from effluents from conventional stirred-tank reactor (CSTR) and fixed-film anaerobic digesters, effluents to which ...

Industrial Odorants: The Relationship between Modeled Exposure Concentrations and Annoyance
Archives of Environmental Health: An International Journal, 1994In a series of epidemiologic studies, the relationship between objective exposure to odorant concentrations emitted by several industrial plants was investigated, as was the relationship between odor annoyance and subjective health complaints. Exposure was determined with a dispersion model of odorants, in which meteorological data and industrial ...
