“…This kind of pollution is one of the most significant causes of environmental discomfort since it lowers the quality of the environment and it may lead to psychophysiological disorders and a general worsened life quality (Palmiotto et al, 2014), which brought several countries to adopt specific regulations for odour impact assessment and control (Sironi et al, 2013). In order to devise proper strategies to manage odour-related nuisance it is necessary to have specific methods for odour emission measurement and for odour impact assessment (Balling et al, 1980;Hobson, 1995;Stordeur, 1981), debunking the common belief, that odour characterization is more art than science (Koe, 1989;Jiang, 1996). While in the scientific community there is a satisfactory agreement regarding the analytical technique to be used for odour emission measurement -i.e.…”

The aim of this study is related to the assessment of odour emissions from landfill surfaces. Up to now, there is not a widely accepted method to quantify odour emissions from this particular kind of source. Five different methods were developed and investigated. These methods can be considered as based on three distinct approaches, both experimental and computational. The first approach provides to use models for the estimation the landfill gas production, whereby the second and the third approach are based on direct measurement campaigns on the landfill surface: for the determination of the methane concentration or for the direct measurement of the odour concentration, respectively. The methods were then compared in terms of specific odour emission rates by referring to other literature data. Finally, dispersion modelling was applied in order to allow a further comparison of the resulting odour impacts with other olfactometric data from independent monitoring campaigns on the studied site.

This article summarises some aspects of investigations carried out into methods available to assess the impact of odours on people living adjacent to large sewage treatment works.The problems of using mathematical modelling techniques in assessing the impact of odours, in particular relatively low level but socially unacceptable odours, are discussed.The conclusion then reached is that the techniques are not sufficiently advanced to yield reliable results.

“…It is generally recognised that for effective odour control measures to be implemented, the problem must first be quantified [1]- [3]. Such quantification of the problem allows designers and caretakers to make informed decisions on the choice of processes, process modifications or the scope of odour control schemes [4].…”

In this study, downwind odour concentrations from a communal toilet facility were measured by trained human receptors using the plume method over a 10 day period from mid-May to mid-June 2015 over an approximate downwind area of 1000 m 2 (about 800 m long and 30 m). Source emission measurements and extensive meteorological data were collected along with the field odor concentration measurements. Modelling of the measurement events at specific receptor locations using the US EPA SCREEN3 model was compared to field odor measurements at the same locations. The study also showed how subjectivity in the use of the human nose in measuring odour strength could be reduced by selecting odour inspectors using the "Standard Procedure for Testing Individual Odour Sensitivity". Also an odour dispersion model using the US EPA SCREEN3 model was built and simulated and the output of the simulated model compared with the measured data. A paired t-test, t(5) = −1.29, p = 0.902 (p > 0.05), showed that there was no statistically significant difference between simulated model output and measured data, hence the possible of using odour dispersion models improved operation of a communal toilet in relation to odour impact.
