Abstract
Odour concentration measurements in a chosen industrial source were made in this study using the method of dynamic olfactometry. The two different scenarios considered the variation of the odour emission rate as input for the dispersion model were compared for the period 2017 (before installation of the equipment for gas treatment) and 2018 (after implementation of purifying technologies). In this paper the odour impact range was determined by applying model calculations conducted in the Polish reference dispersion model – OPERAT FB software for the grid size 2 x 2 km. The conducted research shows a significant improvement in the odour impact range of chosen industrial source in year 2018 compared to 2017.
Highlights
The odour nuisance is related to the emission of odours into the atmosphere
The odour emission from the installation was calculated as mean odour concentration and exhaust gas flow rate on the main/cetral emitter (CE)
The emission of odours into the atmosphere from the industrial plants, especially in urban areas, can cause problems related to odour nuisance, and even negative health effects
Summary
The three main groups of emission sources of odours can be distinguished. They include agriculture and animal husbandry, municipal waste management and industry [1]. Analysis of problems and citizens’ complaints in Poland, related to the odour impact assessment, identified: 16% of the complaints lodged against industrial activities, 34% – about agriculture and breeding, 39% – as result of municipal management and 11% related to other sources [2]. Industrial sources of odour nuisance are characterized by the greatest variety. In this group, a wide range of industrial facilities such as agriculture and food processing industry or chemical industry can be distinguished. Due to the large diversity of products and raw materials, such as dry products as plastics, pharmaceuticals, paints, varnishes, rubber products, fertilizers, acids, products, and semi-finished products from crude oil, the odour nuisance associated with the activity of the chemical industry belongs to the most diverse [1]
