“…Furthermore, 63% of respondents reported that the odor type was offensive. This is consistent with the findings of previous studies [15,16,36,37]. The impact factors of the odor emission by distance to the landfill site is shown in Fig.…”

Landfills are mostly used to manage solid waste in Ho Chi Minh City, Vietnam. Due to inappropriate administration, there have been numerous issues over the years relating to odor and leachate. The purpose of this study is to explore the impact of odor stemming from Da Phuoc landfill site on surrounding areas. A questionnaire survey was administered through face-to-face interviews with 409 residents living in the affected areas. The findings of this study indicate that the odor perception of residents significantly influences their attitudes towards waste disposal sites. The results show that odor affects not only the region around municipal solid waste (MSW) treatment facilities but regions more than 7 km away as well. The data indicates that the odor emanating from the MSW disposal site negatively affects the daily life of many residents. This study is an effort to finding a solution to reduce the impact of odor generated from the landfill site on nearby residential areas.

“…The L, by definition, can approach positive or negative infinity for neutral states, so that the inverse of L (regularly called the Obukhov stability parameter) is evaluated here. Stable atmospheres have positive values of 1/L; unstable atmospheres have negative values of 1/L; neutral atmospheres have |1/L| values of nearly zero [41]. Because the dispersion calculations were conducted by applying the ADJ_U* option, the minimum positive value of L was observed to be 12.3 m. As a consequence, 1/L values were limited to 0.08 m −1 .…”

Concentrated animal feeding operations (CAFOs) such as dairy farms are a source of odorous compound emissions. In this study, by identifying relevant odour sources within a 300-head dairy farm and quantifying their emissions, we determined the separation distances to avoid odour annoyance around the dairy farm with two empirical models (Austrian and German Verein Deutscher Ingenieure (VDI) model) and a dispersion model (AERMOD). Besides, this study ponders on the selection of an appropriate meteorological station that best represents the area surrounding the farm. Results show that the maximum separation distances of an exceedance probability of P = 15% determined by the two empirical and the dispersion models are 524 m, 440 m and 655 m, while the minimum values are 202 m, 135 m, and 149 m, respectively. The NE–SW stretching separation distances match well with the wind rose. The mean ratios of separation distances determined by the two empirical models to that of the dispersion model are 1.23 and 0.95. Moreover, statistics of the separation distances indicate good accordance between the empirical models and the dispersion model.

“…One of the most onerous impacts is odorous impact 3-7 . Odour nuisance can be counteracted in various ways, such as: change of type of resources or technologies, modifi cation of process parameters, increase of ejection point of polluted air to the atmosphere, hermetisation, deodorisation and also -in the case of new objectsproper localization [8][9][10][11][12][13][14][15][16][17][18] . The choice of the optimal solution is possible by modelling odorants dispersion.…”

The purpose of the present article was to determine odour emission rate from primary settling tanks after hermetisation. The paper presents the results of the research on odour emission from four settling tanks, covered with self-supporting aluminium domes with a diameter of 52 meters, located on urban wastewater treatment plants, with the planned flow capacity equal to 200 000 m3/day. Altogether, the olfactometry analysis of 189 samples of polluted air pulled from the domes with the use of an air blower which has efficiency of 12 000 m3/h was conducted. The results of odour concentration measurements were in a range of approximately 10 800 to 763 600 ouE/m3. Average odour emission rate was equal to 102 ouE/(s · m2). The obtained value is much higher than the literature data, available for non-hermetised settlers only. This rate enables better estimation of the odour stream that has to be deodorised after sealing the settling tanks.
