“…In previous epidemiological studies, it has been found that air pollution can be related to respiratory diseases and cardiovascular diseases [29,[32][33][34][35][36]. Most previous relevant studies in Thailand were performed at a small number of locations and, therefore, provided limited evidence for associations between air pollution and health effects [6,[9][10][11][37][38][39][40][41]. We found higher daily mean NO 2 concentrations, PM 10 concentrations, CO concentrations, and temperatures during the study period in Chonburi than the other provinces.…”

“…In addition, the studies performed in Thailand showed the association between a 10 µg/m 3 increase in PM 10 concentration and an increase in cardiovascular mortality (1.90 95% CI 1.00, 2.80) [10]. In Bangkok Metropolitan Region, the odds ratios of respiratory OPD among children per 10 µg/m 3 increase in PM 10 and PM 2.5 were 1.03 (95% CI 1.02, 1.03) and 1.03 (95% CI 1.01, 1.06), respectively [11]. The study of the impact of PM on daily mortality in Bangkok indicated a statistically significant association between PM 10 and cardiovascular and respiratory mortality; a 10 µg/m 3 change in daily PM 10 is associated with a 1-2% and a 3-6% increase, respectively [39].…”

“…The effects of PM on human health are becoming increasingly concerning because epidemiological studies are indicating more links between exposure to PM and adverse health effects. Both short-term and long-term exposure to PM is associated with adverse health effects, including acute outcomes (mortality) [9,10], hospital admissions [6], visits to emergency and outpatient departments (OPDs) [11], absences from school or work [12], acute symptoms [13], chronic disease outcomes (chronic cardiovascular diseases, chronic cardio-respiratory diseases, and lung cancer) [14], and reproductive effects (fetal deaths, low birth weights, pre-term deliveries) [14][15][16]. It is, therefore, important to improve our understanding of the relationships between adverse health effects and air pollution in the EEC of Thailand.…”

The Eastern Economic Corridor in Thailand is undergoing development, but industrial activities are causing serious air pollution. This study aimed to examine the effects of particulate matter (PM10), fine particulate matter (PM2.5), SO2, NO2, O3, and CO on outpatient department (OPD) visits and mortality with various causes in the Eastern Economic Corridor, Thailand between 2013 and 2019 using a case-crossover design and conditional Poisson model. The corresponding burden of disease due to air pollution exposure was calculated. A 1 µg/m3 increase in the PM10 was associated with significant increases in OPD visits for circulatory diseases (0.22, 95% CI 0.01, 0.34), respiratory diseases (0.21, 95% CI 0.13, 0.28), and skin and subcutaneous tissue diseases (0.18, 95% CI 0.10, 0.26). By contrast, a 1 µg/m3 increase in the PM10 was associated with significant increases in mortality from skin and subcutaneous tissue diseases (0.79, 95% CI 0.04, 1.56). A 1 µg/m3 increase in PM2.5 was associated with significant increases in mortality from circulatory diseases (0.75, 95% CI 0.20, 1.34), respiratory diseases (0.82, 95% CI 0.02, 1.63), and skin and subcutaneous tissue diseases (2.91, 95% CI 0.99, 4.86). The highest OPD burden was for circulatory diseases. Respiratory effects were attributed to PM10 exceeding the national ambient air quality standards (NAAQS) of Thailand (120 μg/m3). The highest morbidity burden was for skin and subcutaneous tissue diseases attributed to PM2.5 concentrations that exceeded the NAAQs (50 μg/m3). PM pollution in the EEC could strongly contribute to OPD visits and morbidity from various diseases. Preventing PM10 concentrations from being higher than 60 µg/m3 could decrease OPD visits by more than 33,265 and 29,813 for circulatory and respiratory diseases, respectively. Our study suggests that such pollution increases the risks of OPD visits and mortality in various causes in the Thai EEC. Reducing the ambient air pollution concentration of NAAQSs in Thailand could reduce the health effect on the Thai population.

“…Air pollution can harm the nervous system by increasing oxidative stress, activating microglia cells, and causing brain damage [ 5 ]. Increased PM10 and PM2.5 levels in children have been linked to an increased risk of outpatient department (OPD) visit for respiratory illnesses [ 6 ]. There was a link between PM2.5 exposure and depression, anxiety, and suicide as part of the mental health effects [ 7 ].…”

This article presents the design and fabrication of an air purifier that uses a water-based technique to clean indoor/outdoor transitional air to provide a low-tech air purifier against the annual smog crisis and the ongoing COVID-19 pandemic. The air purifier was designed and built. All tests were conducted in a closed room as well as a semi-outdoor area. Particle sizes of PM0.3, 0.5, 1.0, 3.0, 5.0, and 10 μm (particle/m3) were measured at an air inlet, air outlet, 2 m from an air inlet, and 4 m from an air outlet after 0, 5, 10, 15, and 20 min of air treatment, respectively, as well as CO2 levels and relative humidity (RH). The average airflow rate was also measured. When compare to 0 min, all parameters, except semi-outdoor PM0.3 and CO2 levels, tend to decrease in both indoor and semi-outdoor conditions. When measure by total airflow specification of a dual ventilation fan, the average airflow rate at an air outlet is reduced by 20 times. Article Highlights Design and fabrication of a water-based air purifier. A low-tech air purifier helping to protect against the annual smog crisis and the ongoing COVID-19 pandemic. The novel water-based air purifier effectively traps air particles ranging in size from 0.5 to 10 µm.
