“…Consequently, microbial activity increases, and the released NH 3 and H 2 S concentrations increase. Due to differences in air diffusion conditions, the gas concentrations in the air of the landfill or plant boundary are diluted, and they are notably lower than the initial concentrations directly released from the waste (Sadowska-Rociek et al, 2009; Tansel and Inanloo, 2019).…”

This study examined the release characteristics of malodorous ammonia (NH3) and hydrogen sulphide (H2S) gases in different areas of a full-capacity operational landfill in Hangzhou, China. Gas samples were collected using static boxes from exposed working areas (EWAs), temporarily covered areas (TCAs), and final closure areas (FCAs), and were analysed using spectrophotometric methods. Gas release increased in the following order: TCA > EWA > FCA. The average concentrations of released NH3 in these areas were 2763, 1171, and 27 mg m−3, respectively, and those of H2S were 2481, 631, and 10 mg m−3, respectively. The concentrations of gases released from holes in the film in the temporarily covered and EWAs were significantly higher than the AEGL-3 level values specified by the Acute Exposure Guideline Levels (AEGL) Advisory Committee. EWAs were identified as key for odour control, where the highest NH3 release was recorded at approximately 12:00. The diurnal variation in H2S release was insignificant ( p > 0.05). Therefore, the study shows that working in EWAs should be avoided at approximately noon. Adverse impacts on human health can be reduced by standardising procedures, using higher-quality films, and improving film installation procedures. The results of this study serve as a valuable reference for odour control in operational landfills.

“…A pressure decrease means lower emissions and bad weather; in contrast, increasing pressure indicates higher emissions and good weather. Some other authors also attributed a potential odour decrease in lower temperatures to lower bio-decomposition rates (Tansel and Inanloo, 2019) (Figure 3(c)). SW toxicity based on odour and leached contamination have implications for public health, especially for the communities that are close to SLFs.…”

Despite environmental regulations in Ecuador, particularly in the Province of Azuay, the solid waste final disposal management is still a socio-environmental problem, worsened by weak governance processes. The province has three sanitary landfills with almost expired service lives. The site selection was based on circumstantial reasons, which makes landfills more likely to cause environmental pollution and, therefore, have negative implications for public health. The largest landfill serves Cuenca and also leases service to other small cities. The remaining two are small and, accordingly, have limited technology and fewer resources. In this context, the main aim of this study is to evaluate the terrain of the province to find the most suitable area for landfill siting. A multi-criteria decision analysis, integrated with a geographical information system and analytical hierarchy process methodology, was conducted. Fourteen factors and seven constraints were simultaneously analysed, divided into technical, environmental, social, and economic categories; 15 of these criteria were from the Ecuadorian Unified Text of the Secondary Legislation of the Environmental Ministry. According to the results, 76.17% of the territory is not suitable for landfill implementation, and the unrestricted area represents the remaining 23.83%. The highest landfill suitability index (70–81%) is located in the south of the province in Santa Isabel, Oña, and Nabón cantons, which are dry and clay-rich areas.

“…This is particularly true for plants involved in the treatment and disposal of waste, which are a common source of odour emissions and of consequent concerns for adjacent populations (Ying et al, 2012;Marchand et al, 2013;Sironi et al, 2006). Landfills can be particularly problematic in relation to odour nuisance (Che et al, 2013;Sakawi et al, 2017), and thus require specific protocols for odour control and measurement (Chemel et al, 2012;Lucernoni et al, 2016;Sarkar et al, 2003;Tansel et al, 2019).…”

Influence of Modelling Choices on the Results of Landfill Odour Dispersion

et al. 2020

Landfills are an important source of odour pollution, potentially causing nuisance to adjacent populations. The most commonly used odour impact assessment for this type of plants usually involves a combination of dynamic olfactometry with dispersion modelling. Despite the advantages associated with the use of dispersion models, there are still some important issues related to their uncertainty. The dispersion model requires the Odour Emission Rate (OER) as input, expressed as units of odour emitted per unit time. Source term characterization and the estimation of the OER are typically the most important steps in the model’s implementation, accounting for the highest contribution to the overall uncertainty. Another important element of uncertainty when modelling emissions from landfill surfaces is the geometrical implementation of the emission source in the dispersion model. This entails the definition of the initial dimensions of the emission, which is critical in the case of large area sources. This paper discusses issues related to uncertainty in the use of dispersion models for the evaluation of landfill odour impacts, particularly focusing on the estimation of the OER and the emission’s initial vertical dimension. This study shows that modelling choices may lead to a variance in the resulting modelled odour concentrations at receptors differing by up to a factor 3. This variability should not cause distrust in the method, but rather indicates the importance of having odour dispersion modelling studies carried out by experts with deep knowledge of the physical-chemical mechanisms underlying atmospheric emissions.
