The regulation of odour emissions represents a complex issue to face, due to their strict connection with human perception. For this reason, international legislations offer a variety of different regulatory approaches to control the emissions, to evaluate the odour impact at receptors and to individuate air quality criteria. In Italy there is no national legislation; so, some Regions have adopted different regulatory measures and guidelines in order to take action in case of olfactory annoyance. As public authority involved in environment protection, ARPA Puglia (Regional Agency for Environmental Prevention and Protection) developed a methodological approach for odour regulation, integrating more methodologies, applied to according to local normative. The paper focuses on the development of a regulatory approach for odour control, specifically applied in Puglia.
