“…Fragrance compounds may cause deterioration of quality of life, causing symptoms associated with long-term exposure, including headaches, nausea, concentration problems, loss of appetite, stress, insomnia, and discomfort, which indirectly translates into a desire to stay at a given location [32]. Compared with other forms of air pollution, exposure to odor resulting from human activities is generally considered a nuisance rather than a threat to public health or the environment, as opposed to noise pollution, the measurement, regulation, and effects of which on human health are well known [25,[48][49][50][51].…”

Impact of Odor Nuisance on Preferred Place of Residence

Context of the research:Research is increasingly carried out to take into account the social behavior of residents, the type of industry located in the area, and perceived preference for the place of residence. The quality of life in urban space is increasingly seen as a problem of cooperation between various stakeholders. These studies not only identify factors and sources of odor emissions, but also serve as the basis for creating systems to alert people living in areas adjacent to industrial areas or harmful and unpleasant industrial emissions. In recent years, environmental issues, particularly unpleasant sensory experiences, have been one of the most important acceptance criteria. Aim of the article: The aim of the study is to assess the impact of odor nuisance in the south-eastern part of Kraków (Płaszów) on the residents' decision to leave their place of residence. In particular, the research goal was achieved to indicate which of the unpleasant odors may cause a change of residence, as well as to assess the degree of their impact on the decision to move, taking into account the social and demographic characteristics of residents. New in the article: The novelty of the work was the finding out of the residents' opinions about the quality of life by accepting the place of residence, taking into account the aspect of odor nuisance. Previous studies on odor nuisance have focused on the emission of odors from individual plants. A novelty of this research is its implementation in an urban area, in which numerous industrial plants are located, with various odors emitted. Research methodology: To assess odor nuisance, a measuring tool developed in accordance with VDI 3883 guidelines was used, based on the latest research results on odor and noise nuisance. The questionnaire was developed based on German experience. Conclusions from the research: The data obtained as a result of the research allow us to state that specific smells are so burdensome that they may cause the necessity to leave the place of residence, because the respondents feel various unpleasant smells that have an adverse impact upon the quality of life that they perceive. A possible need for relocation of domiciles out of the current place of residence due to unpleasant smells would affect the perceptible, specific level of grief-the greater it is, the more attached the residents are to their current place of residence.

“…The odorous compounds can have an influence on the deterioration of life quality, causing symptoms associated with long-term exposure, including headaches, nausea, problems with concentration, a loss of appetite, stress, insomnia, and discomfort [3]. Taking into account the unit processes in wastewater treatment plants, it was found that the operations connected with sludge processing constituted the main source of odorous substance emissions [4,5]. Stuetz and Frechen, based on investigations in wastewater treatment plants in Germany and France, revealed that the operations connected with sludge thickening, dewatering, and processing contributed to ca.…”

The Use of Artificial Neural Networks and Decision Trees to Predict the Degree of Odor Nuisance of Post-Digestion Sludge in the Sewage Treatment Plant Process

This paper presents the application of artificial neural networks and decision trees for the prediction of odor properties of post-fermentation sludge from a biological-mechanical wastewater treatment plant. The input parameters were concentrations of popular compounds present in the sludge, such as toluene, p-xylene, and p-cresol, and process parameters including the concentration of volatile fatty acids, pH, and alkalinity in the fermentation sludge. The analyses revealed that the implementation of artificial neural networks allowed the prediction of the values of odor intensity and the hedonic tone of the post-fermentation sludge at the level of 30% mean absolute percentage error. Application of the decision tree made it possible to determine what input parameters the fermentation feed should have in order to arrive at the post-fermentation sludge with an odor intensity <2 and hedonic tone >−1. It was shown that the aforementioned phenomenon was influenced by the following factors: concentration of p-xylene, pH, concentration of volatile fatty acids, and concentration of p-cresol.

“…Because of , among others, the complicated nature of perception of a smell and its assessment, the regulations related to odor nuisance in the European Union and throughout the world are solved on a national or a regional level. Mandatory regulations define following elements in various ways: criteria and acceptable values, including, in the scope of: concentration of the odor (expressed in ouE/m 3 ), reference methods and models and also techniques of control and prevention of odor nuisances [6][7][8], and the considerations dedicated to odors, covered odor-creating features of gases cover among others: concentration, intensity, character, offensiveness, persistency (CICOP), frequency, intensity, duration, offensiveness and location (so called FIDOL) and hedonic tone [6, 8 -10].…”

The problem of odor nuisance requires undertaking legal means that aim towards implementation of regulations in order to improve the odor-related quality of air in selected areas in Poland. So far the works carried out in the country were concluded by drawing up ‘The guidelines for the bill on counteracting the odor nuisance’. However, as a result of completed social consultations in Poland, the Ministry of Environment, in 2015, resigned from implementing of so called anti-odor act. Currently, the legislature is taking steps which aim at undertaking specific actions in order to introduce solutions, which would directly regulate the issues of odors and the odor nuisance, to the national system. In the countries of the European Union, the issues related to odors are solved in diversified ways and the system still lacks of a uniform proposition, among others related to odor standards. In connection with the above, actions that are taken on a national level should fundamentally aim at developing national odor standards which would take into account the type / the kind of economic activity being a source of odor emission (e.g. clearly separated for existing objects and planned investments), at establishing a procedure and also legal and operational requirements related to determination and the types of zones with defined values of acceptable concentration and determination of reference methodology in monitoring, and modeling the dispersion of odors e.g. including strictly defined frequency of necessary tests. In addition, the process should be accompanied by a creation of financial mechanisms and streams in range of investments related to the development of technology and methods used to limit emission of odors.
