Chemical control focused in the characterization of odorous episodes

The chemical characterization of an odour is the only methodology that can answer several questions formulated by both the affected people and the public administrations. Olfatometric techniques only give information about an odour intensity. Chemical control, however, gives information about the concrete compounds that generate the odorous episode, determining which ones can have potentially negative health effects. Additionally, the origin of the odorous source can be determined through concentration maps (Figure 11).
