Description: Odour dispersion models are validated from odour intensity data. gathered by field odour assessors. These odour intensity data are compared to predicted odour concentrations. Odourintensity-concentration relationships exist for manure odours, but not for a reference odour n-butanol gas. A relationship betweenthe intensity of air n-butanol mixtures expressed as an eight-point odour intensity reference scale (OIRS) and the correspondingn-butanol odour concentration by olfactometry was determined. A relationship was found between the n-butanol intensities in aIrand the odour concentration following the definition of 40 ppb = 1 OUm-3. The training protocol used by the odour assessors withthe n-butanol in jars was found to be reliable and repeatable. Livestock odour intensities measured in the field can be low bya factor of three when considering typical odour intensities.
