“…At the same time, our results showed that, although SO 2 was positively correlated with outpatient visits for respiratory diseases in several lag structures, they were negatively related to each other at lag0. Similar results to ours have been reported in other studies (Dong et al 2021 ), and one of the possible reasons is that irritating gaseous air pollutants including SO 2 can cause inflammation in the respiratory tract after several days (Chang et al 2020 ). Quite a few studies stated that the effect of CO on respiratory diseases was positive and has statistically significant effect (Chang et al 2020 ); we also obtained the same result (OR = 1.038, 95% CI: 1.006 to 1.072).…”

Air pollution is a major public health problem throughout the world. Although there have been several studies in this field, most of them have focused on particulate matter and only covered a few key cities. This study aimed to assess a potential association between exposure to gaseous air pollutants and outpatient visits for respiratory diseases in Baotou, China. Daily outpatient visits for respiratory diseases and daily averages of air pollutants and meteorological parameters from 2015 to 2020 were obtained. Time-stratified case-crossover design and restricted cubic splines were used to perform the analyses. Stratified analyses were performed in different hospital departments and districts. Significant association between the concentrations of air pollutants and outpatient visits for respiratory diseases was observed. The odds ratios of outpatient visits for respiratory diseases associated with per 10 μg/m 3 increases in concentrations of NO 2 and SO 2 , and per 10 mg/m 3 increases in concentrations of CO were 1.033 (95% CI: 1.018 to 1.049), 0.965 (95% CI: 0.954 to 0.976), and 1.038 (95% CI: 1.006 to 1.071), respectively. Short-term exposure to NO 2 , SO 2 , and CO was positively associated with outpatient visits for respiratory diseases, with stronger effects among children. The relationship between O 3 and respiratory diseases varied at different concentrations.

“…In Equation ( 4), AF refers to attributable fraction; β i is the regression coefficient of each air pollutant derived from Equation (2); C i is the average concentration of each air pollutant on the i-th day; C 0 refers to a threshold concentration of each air pollutant. Existing studies do not provide evidence for a defined threshold concentration in the exposure-response relationship between air pollutant concentrations and health effects [9]. Threshold concentrations for the acute health effects of O 3 , PM 10 , SO 2 , and NO 2 exposure have also not been determined.…”

“…Previous studies have demonstrated a strong association between air pollutant exposure and respiratory disease, with air pollutant exposure leading to an increased incidence of respiratory disease and mortality. Studies have demonstrated an increased risk of respiratory disease hospital visits when air concentrations of PM 2.5 , PM 10, SO 2 , NO 2 , and CO are elevated [8], and a significant increase in hospital admissions for respiratory disease in children (0-14 years) [9]. Air pollutants have also been associated with respiratory disease deaths, with 25,600, 252,000, 22,300, 57,300, 31,600, and 45,700 deaths attributable to PM 2.5 , PM 2.5-10 , SO 2 , NO 2 , CO, and O 3 , respectively, in China [10], and other countries, such as Mexico [11], India [12], and South Korea [13], have also found a link between air pollution and deaths from respiratory diseases.…”

The Impact of Atmospheric Pollutants on Human Health and Economic Loss Assessment

et al. 2021

The impact of air pollution on human health is becoming increasingly severe, and economic losses are a significant impediment to economic and social development. This paper investigates the impact of air pollutants on the respiratory system and its action mechanism by using information on inpatients with respiratory diseases from two IIIA (highest) hospitals in Wuhan from 2015 to 2019, information on air pollutants, and meteorological data, as well as relevant demographic and economic data in China. This paper describes the specific conditions of air pollutant concentrations and respiratory diseases, quantifies the degree of correlation between the two, and then provides a more comprehensive assessment of the economic losses using descriptive statistical methods, the generalized additive model (GAM), cost of illness approach (COI), and scenario analysis. According to the findings, the economic losses caused by PM2.5, PM10, SO2, NO2, and CO exposure are USD 103.17 million, USD 70.54 million, USD 98.02 million, USD 40.35 million, and USD 142.38 million, for a total of USD 454.46 billion, or approximately 0.20% of Wuhan’s GDP in 2019. If the government tightens control of major air pollutants and meets the WHO-recommended criterion values, the annual evitable economic losses would be approximately USD 69.4 million or approximately 0.03% of Wuhan’s GDP in 2019. As a result, the relevant government departments must strengthen air pollution control to mitigate the impact of air pollution on population health and the associated economic losses.

“…One of these studies performed in Lanzhou, China has determined that females and younger groups were more affected than male and elderly groups. PM 2.5 , PM 10 , SO 2 and CO have been associated with respiratory diseases, out of which SO 2 and CO had the greatest adverse effect [5]. 1220 (2022) 012058 IOP Publishing doi:10.1088/1757-899X/1220/1/012058 2 Pulmonary exacerbations and a decline in lung function represent a major concern when it comes to air pollution especially in patients diagnosed with cystic fibrosis.…”

This paper will focus on analysing the air quality on a frequently congested road section in the vicinity of Timisoara, Romania. The placement of the measurement equipment will be made next to a public transport station measuring the extent of different pollutants which affect the well-being of passengers waiting in these stations. The traffic congestion is present due to the unloading from the highway, reduced capacity of only a one lane road and because of the high amount of industrial area workplaces. The results presented will be part of the PhD thesis of the main author.
