Abstract:

Aim of study: To study the relationship between the problem odours caused by livestock farms and the evolution of rural tourism.Area of study: A coastal region in Spain, the Valencian Community.Material and methods: The odour emission rates of 4,984 farms have been calculated, and the ambient odour concentration was determined to assess the odour nuisance. The odour concentration was modelled by applying the Gaussian model based on emission data and the most unfavourable meteorological conditions of the 45 climatic stations distributed throughout the analysis area.

Abstract:

Odour nuisance generated by food industry objects is a significant problem, the result of which is often numerous complaints from local residents about the quality of air. Apart from the production process, this problem often concerns industrial wastewater treatment processes, which contribute to a large extent to the emissions of odorants from the sulphur group, including hydrogen sulphide and mercaptans. In order to estimate the odorous air quality around these types of objects, the modelling of dispersion of pollutants: odours or odorants is often used. The paper presents the results of tes

Abstract:

The legal basis for any requirement with respect to ambient air quality is the German Federal Protection Act for Ambient Air. According to §3 Federal Protection Act all odours caused by plants are defined as an annoyance. The problem is to find out whether an annoyance has to be considered as a significant disturbance. In the Directive on Odour in ambient air a complete system is designed, beginning with measurement methods and concluding with ambient air quality requirements. In the following paper the tenor of the Directive on Odour is presented, some main aspects of more than five years of

Abstract:

To prove the validity of an odour complaint, a standard evaluation procedure, whereby selected odour compounds are monitored, is proposed for use by Health authorities. The technique determines the dispersion of specific compounds from a point source. Odour threshold limits, determined by specialist odour panels, are used to evaluate the seriousness of the problem. Thereafter, individual waste handling systems are isolated as possible point sources of offensive odours. If dispersion studies and high odour compound concentrations prove the validity of a complaint, individual sites are investiga

Abstract:

Different emission sources of odours become increasingly important environmental problem which may have a negative impact on human health and quality of life. Human odour perception may be subjective, however on odour perception threshold is considered to be the odorant concentration where at least half of odour assessor’s group members confirm the existence of odour, and then it is 1 OUE /m3. Nowadays more and more advanced technologies are used to measure odour concentration. Olfactometer Scentroid SM100 allows users to accurately quantify ambient odour concentration in field.

Abstract:

Abstract The foul odour of cheese-production wastewater is a common problem in areas surrounding dairy wastewater treatment plants. For successful odour management, a better understanding of the key odorants and how to handle them during wastewater treatment is needed. This paper documents the results of using gas chromatography-mass spectrometry coupled with olfactometry (GC-MS/O) to analyze odours emanating from a possibly overloaded treatment plant in Czechia. Using a DB5 capillary column, 20 compounds were detected and identified, nonanal (FDgeomean 152) and octen-3-ol (FDgeomean 2048) hav

Abstract:

Odour capture is an important part of olfaction, where dissolved chemical cues (odours) are brought into contact with chemosensory structures. Antennule flicking by marine crabs is an example of discrete odour capture (sniffing) where an array of chemosensory hairs is waved through the water to create a flow–no flow pattern based on a narrow range of speeds, diameters of and spacings between hairs. Changing the speed of movement and spacing of hairs at this scale to manipulate flow represents a complicated fluid dynamics problem. In this study, we use numerical simulation of the advection and

Abstract:

Abstract Waste management is one of the most relevant problems of environmental protection. Landfills constitute an unavoidable component of the waste management system. The article discusses the problem of landfill odours. Reduction of waste tipping areas and temporary waste covering are the most efficient measures for reducing odours from landfills. The article presents the results of experimental tests on the use of building debris for the reduction of odours from landfills. Tests were performed by applying dynamic olfactometry. Upon covering waste with the building debris layer of 10 cm th

Abstract:

An increasingly frequent problem of people living in urban agglomerations is the occurrence of odour nuisance. Although the source of these nuisances is different, their common feature is that they are a complex mixture of odour compounds with different odour thresholds. However, from a practical point of view, the most valuable would be a direct link between the odour intensity and the results of on-line analytical air monitoring. Such a possibility is created by the use of electronic noses (devices that are supposed to imitate the human sense of smell) to measure odours. The paper presents t

Abstract:

Odours from sewage treatment works are a significant source of environmental annoyance. There is a need for tools to assess the degree of annoyance caused, and to assess strategies for mitigation of the problem. This is the role of odour modelling. Four main stages are important in the development of an odour problem. Firstly, the odorous molecules must be formed in the liquid phase. They must then transfer from the liquid to the gaseous phase. They are then transported through the atmosphere to the population surrounding the odour source, and are then perceived and assessed by that population
