“…Therefore, the output data obtained by means of odor dispersion modeling are typically the "peak" odor concentration values at all points of space-time domain obtained through the application of this "safety" factor F. The applied peak-to-mean factors vary widely from country to country (Piringer et al 2013).…”

This article analyzes the state of the art of the methods and models used for the characterization of odor annoyance and it preliminary advances some proposals for the evaluation of the olfactory nuisance. The use of a sensorial technique, such as dynamic olfactometry, is proposed for the analysis of odor concentrations, odor emission rates, and odor dispersions. A simple model for the quantification of environmental odor nuisance, based on the use of FIDOL factors, that are, frequency, intensity, duration, hedonic tone, and location, is proposed.

“…The choice of the distribution points was made in the prevailing wind direction and included the zone where the odour receptors were prevalent, around the WWTP. Different distances from the source were selected according to the Miedema study [27], for the individuation of the investigation points, ranging from as close to the plant as possible to a distance where the odour was expected to be hardly detectable [42,43].…”

Environmental Odour Nuisance Assessment in Urbanized Area: Analysis and Comparison of Different and Integrated Approaches

Prolonged exposure to odour emissions causes annoyance which leads to nuisance and consequently to complaints. Different methodologies exist in the literature to evaluate odour impacts, but not all are suitable to assess environmental odour nuisance. Information about their applicability criteria and comparison, is scarce and referred to short time analysis. The research presents and discusses the application of different methods to characterize and assess odour nuisance around an industrial plant localized in a sensitive area. Experimental activities are carried out through a long-time analysis programme. Field inspections and predictive methods are investigated and compared. A modification of the traditional dispersion modelling approach is proposed in order to adapt its application for the prediction of the odour nuisance. The offensiveness and location factors are identified as key parameters in the quantification of the perceived nuisance. The integrated dispersion modelling multi-level approach is highlighted as the most suitable for defining the plant strategies. The paper provides useful information to characterize environmental odour problems and identify appropriate solutions for an effective management of odorous sources, with the aim of reducing complaints, restoring the proper relationship between odorous plants and the surrounding communities and increasing the overall quality of the environment.

“…These values are often used in the literature related to the determination of the odour impact of various objects [14,19,21,22]. These values may differ between individual countries depending on the solutions adopted [23]. An example may be the Dutch solutions, where the comparative level of the permissible concentration of odours in the air, considered generally acceptable to humans, is up to 5 ou E /m 3 and the permissible value of the frequency of exceedances of 5 ou E /m 3 equals 2% per year [19,23].…”

The differences between the mentioned values, depending on the solutions used in a given country, may potentially affect the perception of the assessment of odour impact of objects such as agri-food plants, determined with the use of mathematical modelling tools.…”

Within the research, on the premises of an agricultural plant, the odour concentration was measured, and the odour emission was determined. The obtained values allowed us to analyse the odour distribution using the Polish reference mathematical model for four different scenarios, including (1) all identified emission sources, i.e., point and surface: scenarios 1 and 2, and (2) only point sources, scenario 3 and 4. The values of the comparative level and the frequency of exceedances in scenarios 1 and 3 were based on the Polish draft act on counteracting odour nuisance, while the Dutch guidelines were used for scenarios 2 and 4. Model calculations showed the potential impact of the tested structure on adjacent residential areas, i.e., in scenarios 1 and 2, the permissible value of the frequency of exceedances was exceeded at all points representing residential buildings. The exceedances for scenario 3 and 4 took place in seven out of eight and two out of eight points, respectively. The results indicated that to accurately and reliably assess the odour impact and to determine the measures to prevent and reduce odour emissions, it is necessary to consider all types of emission sources in the facilities potentially causing odour nuisance.
