Government departments use the air quality index (AQI) to inform public about how unhealthy is now or may become in future. As AQI increases, so do health threats. In addition reporting daily quality, it also a measure of pollution impacts one’s over limited period time. The was created assist people understanding local affects their health. Therefore, aim this study assess one day 253 towns Ni...

Falling back past few years rapid progress in Air pollution has become a life-threatening concern many nations throughout the world due to human activity, industrialisation, and urbanisation.. As result of these activities, sulphur oxides, carbon dioxide (CO2), nitrogen monoxide (CO), chlorofluorocarbons (CFC), lead, mercury, other pollutants be emitted into atmosphere. Simultaneously, estimati...

In order to realize the accurate prediction of spatial-temporal air quality index, this paper constructs a STAQI model based on deep learning, including data processing, spatial feature acquisition, temporal and prediction. Firstly, interpolation method is used optimize sample set provide reliable data; improved graph convolutional network long short-term memory are effectively extract distribu...

Background & Aim: Particulate matters are of the most important air pollutants, particularly in large cities, having harmful effects on the human’s health and the environment. The present study aimed to investigate of the relationship between meteorological parameters with PM2.5 changes using AQI index in Mashhad from 2014 to 2016. Methods: This study is cross-sectional. Data related to concen...

Aerosol Optical Depth (AOD), quantifying the amount of aerosol in atmosphere, is widely regarded as a crucial indicator for research on atmospheric physics and regional air quality. At present, inversion AOD from observation satellite remote sensing sensors has become main technology large-scale monitoring load. The Huaihai Economic Zone connecting belt two key areas governance (the Yangtze Riv...

Particulate matter (PM) air pollution is associated with atherosclerotic cardiovascular disease. While the biological processes that link PM exposure to disease may also trigger arrhythmias, there are limited data on association of ventricular arrhythmias. The high levels as a consequence 2020 U.S. wildfires provide unique opportunity explore effects cardiac physical activity, and heart failure...
