The Air Quality Index (AQI) is a significant tool of risk communication and reporting system. main aim the paper to comparatively analysis air quality index both Delhi Chennai. objective study compute AQI cities compare it. For data for computation are taken from secondary source Central Pollution Control Board (CPCB) Tamil Nadu (TNP). It found that in city pollution anthropogenic natural genes...

Air pollution has become an essential issue in environmental protection. The Quality Index (AQI) is often used to determine the severity of air pollution. When AQI reaches red level, proportion asthma patients seeking medical treatment will increase by 30% more than usual. If can be predicted advance, benefits early warning achieved. In recent years, a scholar proposed α-Sutte indicator which s...

This paper reports the results of the investigation of air pollution from automobiles at intersections on some selected major roads in Ogbomoso, South Western, Nigeria. Four sampling routes were considered with ten sampling points (SP1 – SP10) placed 2.0m away from the edge of the road. Priority parameters: SO2, NOx, CO were monitored. The results of SO2, NOx, CO were in the range of 0.02 – 0.0...

This study investigates the potential utility of the application of a photochemical modeling system in providing simultaneous forecasts of ozone (O3) and fine particulate matter (PM2.5) over New York State. To this end, daily simulations from the Community Multiscale Air Quality (CMAQ) model for three extended time periods during 2004 and 2005 have been performed, and predictions were compared ...

Urbanization affects the quality of air, which has drastically degraded in past decades. Air level is determined by measures several air pollutant concentrations. To create awareness among people, an automation system that forecasts needed. The COVID-19 pandemic and restrictions it imposed on anthropogenic activities have resulted a drop pollution various cities India. overall index (AQI) at an...

Fine particles (PM2.5) have adverse impacts and risks on air quality human health. The present research focuses the concentrations of PM2.5, index (AQI), assessment hospital admissions due to COPD attributed PM2.5 particle levels in Tehran during last 10 years from 2011 2020. effects meteorological parameters (i.e., wind speed, humidity, temperature) AQI were examined using data 21 active monit...

Air pollution and lung cancer are closely related. In 2013, the World Health Organization listed outdoor air pollution as carcinogenic and regarded it as the most widespread carcinogen that humans are currently exposed to. Here, grey correlation and data envelopment analysis methods are used to determine the pollution factors causing lung cancer among residents in Nanchang, China, and identify ...

Ambient (outdoor) air pollution is now recognized as an important problem, both nationally and worldwide. Our scientific understanding of the spectrum of health effects of air pollution has increased, and numerous studies are finding important health effects from air pollution at levels once considered safe. Children and infants are among the most susceptible to many of the air pollutants. In a...

The Air Quality Index (AQI) dataset contains information on measurements of pollutants and ambient air quality conditions at certain location that can be used to predict quality. Unfortunately, this often has many missing observations imbalanced classes. Both these problems affect the performance prediction model. In particular, predictions for minority class are very important because inaccura...

The rapid urbanization in China the last decade has brought about severe air pollution problems. To provide a theoretical basis for improving environment, this paper analyses quality’s spatial and temporal evolution 13 prefecture-level cities Hubei Province. It influence of various indicators on AQI. Based existing literature, selects six to measure level each city three dimensions: population,...
