“…Regarding chromatographic separation, previous studies for RSC determination used high apolar columns (e.g. DB-1) or long columns composed by 185 diphenyl dimethyl polysiloxane [5,15]. In the present research, the selected column was 5MS column with a length of 30 m, based on the better results obtained in our previous study for the single detection of CS2 [18].…”

“…Then, the sources of malodor are found to be including a variety of man-made activities such as chemical plants, oil refineries, sewage and wastewater treatment plants, landfills, livestock facilities, among others [2,3]. These emissions are mainly composed of volatile chemicals, such as alcohols, 50 fatty acids, aldehydes, ketones, inorganic nitrogen derivates, organic and inorganic sulfur compounds [4,5]. Between them, reduced sulfur compounds (RSCs) have a relevant contribution, yielding very unpleasant odor perceivable by humans [2].…”

A reliable method for determining malodorous reduced sulfur compounds (RSC) in atmospheric samples has been developed. The method uses an activated coconut 25 solid-phase sorbent for active sampling, hexane as desorption solvent, and gas chromatography-mass spectrometry (GC-MS) technique for specific and sensitive separation-detection. The compounds analyzed were hydrogen sulfide, ethyl mercaptan, dimethyl sulfide, carbon disulfide, butyl mercaptan and dimethyl disulfide.

“…Studies have shown that sulfides were the main compounds causing landfill-generated odors and that many other complex trace substances also contributed to those odors (Allen et al, 1997;Ding et al, 2012;Duan et al, 2014;Kim et al, 2005;Sarkar et al, 2003;Scheutz and Kjeldsen, 2003;Young and Parker, 1983;Ji, 2011). Governments regulate siting of landfills by specifying the minimum distance between landfill sites and residential areas.…”

a b s t r a c tLandfill odors have created a major concern for the Chinese public. Based on the combination of a first order decay (FOD) model and a ground-level point source Gaussian dispersion model, the impacts from odors emitted from the 1955 landfills in China are evaluated in this paper. Our bottom-up approach uses basic data related to each landfill to achieve a more accurate and comprehensive understanding of impact of landfill odors. Results reveal that the average radius of impact of landfill odors in China is 796 m, while most landfills (46.85%) are within the range of 400e1000 m, in line with the results from previous studies. The total land area impacted by odors has reached 837,476 ha, accounting for 0.09% of China's land territory. Guangdong and Sichuan provinces have the largest land areas impacted by odors, while Tibet Autonomous Region and Tianjin Municipality have the smallest. According to the CALPUFF (California Puff) model and an analysis of social big data, the overall uncertainty of our calculation of the range of odor impacts is roughly À32.88% to 32.67%. This type of study is essential for gaining an accurate and detailed estimation of the affected human population and will prove valuable for addressing the current Not In My Back Yard (NIMBY) challenge in China.

This study looks at the annual variations in landfill gas concentrations within the surface layer of the dump as well as the effect of climatic factors on these variations under the tropical climate. The experiment was carried out at part of the Karadiyana landfill, Sri Lanka, containing old mixed municipal solid waste covered by vegetation. The gas concentrations of the landfill surface layer were measured from three gas wells established on the dump surface layer, which contains 2.5 m depth, throughout the year with the measuring of climatic factors. The results show the annual fluctuation of temperature, cumulative rainfall, relative humidity, and atmospheric pressure were 27–42°C, 66.7–357.7 mm, 24.7%–78.2%, and 999.5–1014 mbar around the studied landfill area, and the average concentration value of the CH4, NH3, H2S, and VOCs gases were 18.94 ± 11.49%, 15.48 ± 15.17 mg m−3, 15.06 ± 19.02 mg m−3, and 0.83 ± 0.99 mg m−3, respectively. The rainfall and atmospheric temperature were significant metrological factors influencing the surface layer gas concentrations and showed a significant positive correlation with cumulative rainfall and a negative correlation with atmospheric temperature. The relative humidity shows a moderate positive correlation, and there was no evidence of a considerable impact of atmospheric pressure on the surface layer concentrations. Annual fluctuation is a critical factor for landfill gas emission quantification, and surface layer concentration variation can be used to study the emission fluctuation by considering their relationship.
