“…The first test reveals the significant differences between the defined groups by comparing the medians of the SO 2 concentration (Chávez, 2020 ). The second test was used post hoc to compare the pairing of each group, where a Bonferroni adjustment was necessary to increase the level of significance required (Boso et al, 2019 ; Dinno, 2015 ). The analyses of both tests were carried out with the kruskal.test and pairwise.wilcox.test functions of the statistical software R version 4.0.3, respectively (R Core Team, 2021 ).…”

La Oroya is a city in the Peruvian Andes that has suffered a serious deterioration in its air quality, especially due to the high rate of sulfur dioxide (SO 2 ) emissions, which underlines the importance of knowing its sources of contamination and variation over the years. In this sense, this study aimed to evaluate the immission levels and determine the sources of SO 2 contamination in La Oroya. This analysis was performed using the hourly concentration data of SO 2 , and meteorological variables (wind speed and direction), which were analyzed for a period of three years (2018–2020). Graphs of time series, wind and pollutant roses, bivariate polar graphs, clustering k-means, nonparametric statistical tests, and the application of the conditional bivariate probability function were performed to analyze the data and identify the emission sources. The mean concentration of SO 2 was 264.2 μg m −3 for the study period, where 55.66 and 2.37% of the evaluated days exceeded the guideline values recommended by the World Health Organization and the Peruvian Environmental Quality Standard for air for 24 h, respectively. The results showed a defined pattern for the daily and monthly variations, with peaks in the morning hours (0900–1000 h LT) and at the end of the year (December), respectively. The main sources of SO 2 emissions identified were light and heavy vehicles that travel through the Central Highway, the La Oroya Metallurgical Complex, the transit of vehicles within the city, and the diesel–electric locomotives that provide cargo transportation services and tourism passenger transportation. The article attempts to contribute to the development of adequate air quality management policies.

“…However, some studies found no difference between how genders perceived air pollution. Low levels of education and socio-economic status may reduce the ability to perceive hazards (Boso et al 2019). People with no schooling perceived the mining impacts on the environment to be very less (Macêdo Coelho et al 2022).…”

Air pollution perception for air quality management: a systematic review exploring research themes and future perspectives

Air pollution is perceived through sensory stimuli and interpreted by our brain. Perception is highly subjective and varies from person to person. As many direct and indirect factors influence air pollution perception, it is difficult to unearth the underlying mechanisms. Many studies have tried to understand the mechanisms and relations affecting perception, and it is important to evaluate those different approaches.We systematically reviewed 104 studies on air pollution perception, following the PRISMA guidelines. There is a difference between the public's subjective perception and objective air quality measurements. This discrepancy has been found to occur due to varied socio-economic characteristics, knowledge, emotions, etc. The advent of social media and the internet has had a significant effect on risk perception. All these influencing factors create differences between the public's perception and the scientific community/policymakers. This gap can be fixed by tailoring science-backed information for better communication. Based on past studies, we highlight the need for tailored data dissemination, integration of big data for urban management, development of robust frameworks to incorporate perception and use of a perception index for better communication.

“…For instance, studies have shown that concern about pollution tends to be higher among women [33][34][35]. Age seems to be associated with air pollution perception in a non-consistent way [36][37][38][39]. Kim, Hi, and Kim [40] have discovered higher levels of air pollution perception among young people.…”

“…Forsberg, Stjernberg, and Wall [41] and Williams and McCrae [42] have indicated that middle-aged people are more sensitive to air pollution risks. A recent study in southern Chile showed that older adult women perceive the health risk of woodsmoke as less severe [39]. Several studies have found that individuals with higher levels of income and education tend to be more concerned about the impacts of air pollution on their health and largely tend to support mitigation policies [43][44][45].…”

Wood-burning pollution is a severe problem in southern Chile, where every winter, people are exposed to unhealthy ambient fine particulate matter (PM2.5) concentrations. Urban air quality is a major concern for health officials, but public awareness campaigns tend to focus on outdoor hazards. Our understanding of how residents are exposed and perceive air pollution risks in their homes remains incomplete. This study explores the ability of participants to perceive indoor air quality. We collected data on 81 households, combining perceptions of air quality with objective measurements of PM2.5. Residents’ evaluations of air quality were systematically compared to inspectors’ evaluations in order to examine the home halo effect. We found that residents tended to overestimate air quality in their homes. We discuss how our data supported the existence of a home halo effect, but also point out the possibility that individuals’ ability to perceive air quality in indoor spaces is limited by other factors.
