ILC20   Once again, the German company Olfasense is behind the organization of the 2020 proficiency test for Dynamic Olfactometry according to the European Standard EN 13725. The registration period fo this test has started and organizers invite laboratories from different countries to participate in this ILC2020 test.

   The EN 13725 interlaboratory comparison test allows odour laboratories all around the world to demonstrate compliance with their performance requirements and compare the performance of any laboratory internationally. This is essential for those laboratories that maintain ISO 17025 accreditation.

P14I1   One way to assess odour nuisance is to apply a survey to the area of influence of an activity that potentially impacts the surrounding community. Repeated surveys were carried out in neighbours of the waste water treatment plant at Chimbarongo, Chile, during the years 2017 and 2018, using the VDI3883/1 model questionnaire.

   In parallel, an odour impact measurement was carried out by means of field inspection, using a simplified methodology of VDI3940/1. Odour hour frequencies were generally determined well below the German regulatory threshold of 10%, which was also supported by ex-ante odour dispersion modeling.

P05I3   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.
