Abstract
Characterization of malodorous organic volatiles, arising from animal breeding stations and from the coke and steel industry was performed by means of dynamic headspace enrichment (active charcoal-CS2 method) followed by capillary gas chromatography with olfactive and/or mass spectrometry detection. The results were associated to olfactive threshold values from the literature in order to present circular odour charts reflecting both the quality and the intensity of the odour sample. These charts, by visually indicating the respective contributions of specific chemical classes to the global odour, could help to elaborate the abatement techniques.
