“…As a result of breathing the same air,overcrowding in public transport will cause infectious diseases to spread easily, including diseases related to breathing. Second, they breathe more air than the elderly group because they have larger lung capacities [27]. This is also supported by the data from this study that, the difference in elderly group admission due to respiratory diseases was 12.32% lower than the working age group.…”

Numerous studies have been conducted in other countries on the health effects of exposure to particulate matter with a diameter of 10 microns or less PM10 , but little research has been conducted in Malaysia, particularly during the haze season. This study intends to investigate how exposure of PM10 influenced hospital admissions for respiratory diseases during the haze period in peninsular Malaysia and it was further stratified by age group, gender and respiratory diseases categories. The study includes data from all patients with respiratory diseases in government hospitals, as well as PM10 concentration and meteorological data from all monitoring stations in peninsular Malaysia starting from 1st January 2000 to 31st December 2019. A quasi-poison time series regression with distributed lag nonlinear model (DLNM) was employed in this study to examine the relationship between exposure of PM10 and hospital admissions for respiratory diseases during the haze period. According to the findings of this study, PM10 was positively associated with respiratory disease admissions within 30 lag days under various lag patterns, with lag 25 showing the strongest association (RR = 1.001742,CI : 1.001029,1.002456). Using median as a reference, it was discovered that females were more likely than males to be hospitalized for PM10 exposure. Working age group will be the most affected by the increase in PM10 exposure with a significant cumulative RR from lag 010 to lag 030. The study found that PM10 had a significant influence on respiratory hospitalisation in peninsular Malaysia, particularly for lung diseases caused by external agents(CD5). Therefore, it is important to implement effective intervention measures to control PM10 and reduce the burden of respiratory disease admissions

“…32 Furthermore, both epidemiological and experimental studies have demonstrated that exposure to gaseous pollutants can induce systemic vascular oxidative stress and contribute to thrombus formation, thereby increasing the risk of cardiovascular diseases. 33,34 However, the current body of evidence about the association between exposure to gaseous pollutants at the hourly level and risk of stroke remains limited.…”

BACKGROUND: Daily exposure to ambient air pollution is associated with stroke morbidity and mortality; however, the association between hourly exposure to air pollutants and risk of emergency hospital admissions for stroke and its subtypes remains relatively unexplored. METHODS: We obtained hourly concentrations of fine particulate matter (PM 2.5 ), respirable particulate matter (PM 10 ), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ), ozone (O 3 ), and carbon monoxide (CO) from the China National Environmental Monitoring Center. We conducted a time-stratified case-crossover study among 86 635 emergency hospital admissions for stroke across 10 hospitals in 3 cities (Jinhua, Hangzhou, and Zhoushan) in Zhejiang province, China, between January 1, 2016 and December 31, 2021. Using a conditional logistic regression combined with a distributed lag linear model, we estimated the association between hourly exposure to multiple air pollutants and risk of emergency hospital admissions for total stroke, ischemic stroke, hemorrhagic stroke, and undetermined type. RESULTS: Hourly exposure to PM 2.5 , PM 10 , NO 2 , and SO 2 was associated with an increased risk of hospital admissions for total stroke and ischemic stroke. The associations were most pronounced during the concurrent hour of exposure and lasted for ≈2 hours. We found that the risk was more pronounced among male patients or those aged <65 years old. CONCLUSIONS: Our findings suggest that exposure to PM 2.5 , PM 10 , NO 2, and SO 2 , but not CO and O 3 , is associated with emergency hospital admissions for total stroke or ischemic stroke shortly after exposure. Implementing targeted pollution emission reduction measures may have significant public health implications in controlling and reducing the burden of stroke.

“…Researches have shown that O 3 can lead to an imbalance in heart rate variability and an increased sensitivity to myocardial calcium load, which can trigger vascular and cardiac injury, ultimately manifesting as cardiovascular disease ( 59 , 60 ). SO 2 can reduce the permeability of red blood cells and lead to organ shortages, while short-term exposure to it can lead to a decreased in cardiac vagal control measures ( 61 ). NO 2 is considered a proxy for traffic-related pollutants and is often found in conjunction with traffic noise, which is also associated with adverse cardiovascular health outcomes ( 62 ).…”

ObjectivesExposure to air pollution has been linked to an increased risk of premature mortality. However, the acute effects of air pollution on the risk of non-accidental mortality have not been extensively researched in developing countries, and the findings thus far have been inconsistent. Therefore, this study aimed to examine the association between short-term exposure to six pollutants (PM2.5, PM10, SO2, NO2, O3, and CO) and non-accidental mortality in Beijing, China.MethodsDaily data on non-accidental deaths were gathered from 1 January 2017 to 31 December 2018. Air pollution data for the same period were collected from 35 fixed-site air quality monitoring stations in Beijing. Generalized additive models (GAM) based on Poisson regression were used to investigate the association between non-accidental mortality in emergency department visits and the daily average levels of air pollutants.ResultsThere were 8,676 non-accidental deaths recorded during 2017–2018. After sensitivity analysis, short-term exposure to air pollutants, particularly gaseous pollutants, was linked to non-accidental mortality. Specifically, for every 10 μg/m3 increase (5 μg/m3 in SO2, 0.5 mg/m3 in CO) of SO2 (lag 04), NO2 (lag 04), O3 (lag 05), and CO (lag 04), the relative risk (RR) values were 1.054 (95% CI: 1.009, 1.100), 1.038 (95% CI: 1.013, 1.063), 1.032 (95% CI: 1.011, 1.054), and 1.034 (95% CI: 1.004, 1.066), respectively. In terms of causes of death, short-term exposure to NO2, SO2, and O3 increased the risk of circulatory mortality. Further stratified analysis revealed that the stronger associations were presented in females for O3 while in males for CO. People aged 65 and over were strongly associated with ambient air pollution.ConclusionsOur study showed that ambient air pollutants were associated with non-accidental mortality. Our findings suggested that efforts to control gaseous pollution should be stepped up, and vulnerable groups should be the focus of health protection education.
