Molina’s industrial area, located in La Talaudiere, (France), has been generated a potential conflict at the residential area located in the surroundings, due to the industrial activity. An odour impact assessment study, managed by the Departmental Direction of Population Protection of La Loire (DDPP), was developed in 2 main areas (1) principal sources identified at the industrial area (2) headspace ambient air at collectors and discharge to sewage networks public system. Results show odour concentration according to EN13725 and Calpuff modelling impact assessment.

   Physicochemical parameters were measured in headspace’s collectors; also, intensity, hedonic tone and molecular characterization were evaluated by GC-TOF-MS. These results allowed to integrate control and monitoring actions at the industries, evaluating results at short and medium term. It should be noted that regular and transparent exchanges with all stakeholders were essential for the success of the project and goal’s achievement.

   The Web-App NOSE is a free application that allows citizens to send their geo-referenced and real-time reports about odour episodes in a confidential and anonymous way to the Regional Environmental Ministry of Sicily. Mr Cordaro and Anna Abita from the Regional Environmental Ministry of Environment of Sicily and Paolo Bonasoni from the Institute of Atmospheric Science and Climate (ISAC) of Italy presented last week the preliminary results of a 2-year study on odour mapping funded by the Sicilian Region and co-financed by the ISAC.

   This study commenced at the end of August 2019 in the area of Syracuse and In 4 months, 3200 odour observations have been collected from 2000 registered citizens. 2400 times the citizens have reported the smell of hydrocarbons, 271 times they reported sulfurs and 180 times they smelled solvents. Regarding intensity, 1500 reports recorded a maximum level intensity (5) and 1100 observations registered an intensity of 4. Finally, this app offers the possibility to register a health issue. In this sense, 1500 participants reported difficulty breathing, 1300 burning and irritation in the throat and 1100 headache.
