Air quality has a significant influence on the environment and health. Instruments that efficiently inexpensively detect air could be extremely valuable in detecting indices. This study presents robust deep learning model named AQE-Net, for estimating from mobile images. The algorithm extracts features patterns scene photographs collected by camera device then classifies images according to ind...

Urban air pollution is one of the most visible environmental problems to have accompanied China’s rapid urbanization. Based on emission inventory data from 2014, gathered from 289 cities, we used Global and Local Moran’s I to measure the spatial autorrelation of Air Quality Index (AQI) values at the city level, and employed Ordinary Least Squares (OLS), Spatial Lag Model (SAR), and Geographical...

Under the National Ambient Air Quality (NAQM) Monitoring program, air quality in the city of Cochin is being regularly monitored by Central Pollution Control Board. Air quality management programme requires reliable information of air quality collected, evaluated and analysed regularly. This is of paramount importance in protecting man and his environment from damaging exposure to air pollution...

The air quality index (AQI) can be described using different pollutant indices. Many investigators study the effect of stock prices and in field to show if there is a relationship between changing market concentration various pollutants. This aims find Saudi Tadawul All Share Index (TASI) multiple pollutants, including particulate matter (PM10), ozone (O3), nitrogen dioxide (NO2), sulfur (SO2),...

The COVID-19 pandemic has induced changes in global air quality, mostly short-term improvements, through worldwide lockdowns and restrictions on human mobility industrial enterprises. In this study, we explored the pollution status Tehran metropolitan, capital city of Iran, during outbreak. To end, ambient quality data (CO, NO2, O3, PM10, SO2, AQI) from 14 monitoring stations across city, toget...

BACKGROUND We quantified the air quality benefits of a smoke-free workplace law in Boston Massachusetts, U.S.A., by measuring air pollution from secondhand smoke (SHS) in 7 pubs before and after the law, comparing actual ventilation practices to engineering society (ASHRAE) recommendations, and assessing SHS levels using health and comfort indices. METHODS We performed real-time measurements ...
