Spotlights the six major air pollutants identified by the Clean Air Act for which the Environmental Protection Agency must set national standards in the United States. Ozone; Particulate matter; Nitrogen Dioxide; Lead; Carbon Monoxide; Sulfur Dioxide; Characteristics of these pollutants; Sources; ...
The monitoring sites of air pollutants have been stable in 366 cities in China since January 2015. Therefore, the purpose of this study is to understand the temporal and spatial variations of PM2.5, PM10, SO2, NO2, CO, and O3in 366 cities from 2015 to 2017. We analyzed the variations o...
The first study assessed the impact of air pollution control policy on AMI morbidity.The GAM developed using an ITS design was used to assess the impact of policy on AMI.Immediate decreases observed in PM2.5, PM10, SO2, CO concentrations after the policy issued.The health effect of the policy...
The winter months in India bring higher concentrations of harmful pollutants, particularly in major cities like Delhi, Mumbai, and Kolkata. During this time, air quality worsens, and heart health can be significantly affected. According to the World Health Organisation, air pollution contributes to ...
It is defined based on the Air Quality Index (AQI) system. Daily individual AQI values are calculated using concentrations of individual pollutants. The pollutant that has the maximum AQI is then defined as the major pollutant on that day (Cheng et al., 2007). Fig. 9 illustrates the major...
Moreover, an increase in air pollutants per se has been found to be associated with smaller total cerebral brain volume and a higher risk of covert brain infarct9. Importantly, several studies have found an association between unclean cooking fuel and cognitive impairment. For example, in one ...
A unified spatiotemporal modeling approach for predicting concentrations of multiple air pollutants in the multi-ethnic study of atherosclerosis and air po... Cohort studies of the relationship between air pollution exposure and chronic health effects require predictions of exposure over long periods of ...
were identified and quantified. Source emission models were developed to predict the time/concentration profiles of the major VOCs (limonene, α-pinene, β-pinene, 3-carene, camphene, benzyl propionate, benzyl alcohol, bornyl acetate, isobornyl acetate, and benzaldehyde) emitted by the air freshener...

(Herath et al.2021,2023). Moreover, integrating green roofs with solar panels shows a higher efficiency in energy production (increasing energy gain by up to 16%) compared with using conventional solar roofs, as this combination eliminates pollutants in the air while maintaining the panel ...
