Evaluation of odour annoyance through repetitive surveys - Evidence from a case study

There is no translation available.

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.

Odorous compounds emissions in an urban and industrialized area

There is no translation available.

   In industrialized cities, there are many possible sources of odorous compounds, such as steel and pelletizing industries, wastewater treatment plants, landfills, and harbors. For most of these sources, limited data is available on odours emissions in inventories. To estimate odorous VOCs in gaseous emissions from industries it is necessary to identify which VOCs are emitted and are odorous.

   Although reasonably simple, there are few papers addressing this issue. Thus, this study aimed to categorize chemically the VOCs and TRS emissions from major activities in an industrialized urban area of Brazil, crossing references with U.S. EPA - AP 42 documents, SPECIATE 4.5 database, and literature available.

Odours’ identification and characterisation; calpuff impact assesment study in the region of La Talaudière (France), the Molina’s industrial area

There is no translation available.

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.
