Dynamic olfactometry and modelling as methods for the assessment of odour impact of public utility objects

Abstract

The methods used to the identification of odour concentrations from public utility objects, under Polish legal regulations have been presented with exemplary results of measurements by the dynamic olfactometry and model calculations. The results of the study indicate the usefulness of the dynamic olfactometry in determining odour concentrations (from point and area emission sources located in public utility objects) suitable in odour emissions calculations. Based on results of such calculations, it is possible to determine odour concentrations in the receptor points and to evaluate olfactory impact range of considered objects, taking into account all types of odour sources affecting the quality of air in the area under study. Selected methods – as an alternative to field research: measurements in the grid and in the plume – can be less time and cost consuming but also require careful planning the number of samples and proper selection of representative sampling areas, especially in the case of the area sources
