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.

centc264wg2 meeting 2020 delft   2020 is here and, once again, Working Group 2 of the CEN Technical Committee 264 got to meet in Delft (The Netherlands) the 21st and 22nd of January to discuss the coming revision of the EN 13725. The final draft of the revision process of the Standard EN 13725 on Dynamic Olfactometry was sent to enquiry and many comments have been received from different countries. A document of over 100 pages was produced with all the comments received. The work of the group was at this stage to answer to each one of the comments.

 Secretary and convenor of the group collated a table with every comment and modified and replied to many of the suggestions received. Some comments were left to discussion within the group of 16 experts that got to meet at NEN facilities in Delft.
