“…On the other hand, the increased prevalence of respiratory symptoms may also affect the burning of solid waste at the open dumpsites in the gers districts. There still has a problem with solid waste, coal ash and other rubbish, and also low-income households burn old tires, plastic bottles [39, 40]. Das B et al reported that open burning of municipal solid waste is a poorly characterized and frequently underestimated source of air pollution.…”

BackgroundChildren in Ulaanbaatar are exposed to air pollution, but few epidemiological studies have been conducted on the effects of environmental risk factors on children’s health. Also, no studies have yet examined the prevalence of respiratory symptoms in children in suburban areas, where air quality-monitoring stations have not yet been installed. This cross-sectional study evaluated the associations between outdoor air pollution and respiratory symptoms among schoolchildren in urban and suburban districts of Ulaanbaatar.MethodsThe ATS-DLD-78 C questionnaire was used to investigate the respiratory symptoms of schoolchildren aged 6–12 years (n = 1190) who lived in one of three urban districts or a suburban district of Ulaanbaatar. In each district, the outdoor concentrations of nitrogen dioxide (NO2) and sulfur dioxide (SO2) were measured at two sites (at ≤100 m and > 100 m from the nearest major road) in the 2-year period from 2015 to 2016. The associations between health outcomes and exposure to air pollutants were estimated using the multinomial logistic regression method.ResultsThe outdoor concentration of SO2 was significantly associated with persistent cough symptom (OR = 1.12, 95% CI 1.04–1.22). Furthermore, the outdoor concentration of NO2 was significantly associated with the current wheezing symptom (OR = 1.33, 95% CI 1.01–1.75) among children in urban and suburban.ConclusionsThe prevalence of persistent cough symptom was markedly high among the schoolchildren in urban/suburban districts of Ulaanbaatar. Overall, the increases in the prevalence of respiratory symptoms among children might be associated with ambient air pollution in Ulaanbaatar.

“…Section C comprised 10 items devoted to measuring the solid waste management practices of the respondents. Items in Section B were adapted from the questionnaires used by previous studies on solid waste management (such as (Delgermaa & Matsumoto, 2016;Fratta, Toneli, & Antonio, 2019;Moghadam, Mokhtarani, & Mokhtarani, 2009;Radha, Kalaivani, & Lavanya, 2009)). Respondents rated the extent to which they agreed or disagreed with the statements on a four-point Likert agreement scale.…”

This research investigated the correlation between individuals' age, attitude, and practices in handling solid waste in Cross River State, Nigeria. The study formulated three hypotheses to guide its direction and utilised a survey research design. The participants included 1,106 individuals selected through random sampling from a population of 6,923 using a stratified approach. The researchers developed a questionnaire, which six experts validated, and its reliability was assessed using Cronbach's alpha method. Various statistical methods were employed to test the hypotheses at a significance level of 0.05, including simple regression, one-way analysis of variance (ANOVA), and an independent t-test. The outcomes revealed that age, gender, and self-concept influenced solid waste management practices within the studied population. Specifically, males and individuals with a strong self-concept exhibited more active engagement in solid waste management than their female and low-self-concept counterparts. The data indicated that respondents aged 38 and above demonstrated the highest level of involvement in solid waste management, followed by those aged 18-27. Conversely, respondents aged 28-37 exhibited the lowest extent of engagement in solid waste management practices. This study has valuable implications for policymakers, waste management professionals, and community stakeholders. The insights can guide the development of evidence-based strategies to encourage responsible waste management behaviours, thereby contributing to a cleaner and more sustainable future.

“…However, there is a lack of waste separation at the source in Mongolia that needs to be addressed [5,50]. In Mongolia, it is possible to cut the total solid waste disposed of at landfills by 30-40% if recyclable wastes are sorted and collected [4]. The outcomes of this study can help policymakers, local practitioners, and urban managers formulate suitable policies and strategies, and thus enhance households' participation in HWS.…”

“…The improper management and mishandling of waste pose a substantial danger to human health, sustainable economic development, and environmental wellbeing [2,3]. Delgermaa and Matsumoto [4] argued that if wastes are presorted and collected, it is possible to cut the total solid waste disposed at landfills by 30-40% in Mongolia. Households are the foremost source of waste, and enhancing household waste separation (HWS) will reduce waste generation, improve municipal solid waste management systems, and mitigate adverse consequences [5][6][7].…”

Household Waste Separation Intentions in Mongolia: Persuasive Communication Leads to Perceived Convenience and Behavioral Control

et al. 2021

This study contributes by developing a set of household waste separation (HWS) attributes to address waste mishandling and to enhance waste separation intentions in households. In Mongolia, a lack of waste separation at the household level needs to be addressed to improve municipal solid waste management systems. However, prior studies have not established attributes in a hierarchical structure, nor do they understand their cause-effect interrelationships. First, the fuzzy Delphi method (FDM) was used to screen out the unnecessary attributes in qualitative information. The fuzzy decision-making trial and evaluation laboratory (FDEMATEL) was then applied to understand the hierarchical structure of the attributes and their cause-effect interrelationships. The study identifies a valid set of attributes consisting of five aspects and 17 criteria under uncertainties. A hierarchical framework consisting of environmental attitudes, social norms, perceived behavioral control, perceived convenience, and persuasive communication is provided. The findings reveal that persuasive communication and environmental attitudes are causal group aspects. Furthermore, persuasive communication has a strong causal impact and higher importance in improving HWS intentions, and it leads to perceived convenience and behavioral control. For policymakers, credibility of information, knowledge and information, awareness of consequences, willingness to sort, and perceived policy effectiveness are the key causal criteria for enhancing HWS intentions. Theoretical and practical policy implications are discussed.
