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...

Introduction: Due to more than 1.7 million population, many vehicles and large industries around Isfahan, it has become one of the most polluted cities in Iran. The aim of this study was a spatial analysis of the concentrations of air pollutants and the air quality index (AQI). Materials and Methods: In this descriptive and evaluative study, the air quality data of 7 monitoring stations in 201...

Background: Air pollution and concerns about health impacts have been raised in metropolitan cities like Tehran. Trend and prediction of air pollutants can show the effectiveness of strategies for the management and control of air pollution. Artificial neural network (ANN) technique is widely used as a reliable method for modeling of air pollutants in urban areas. Therefore, the aim of current ...

Dynamic traffic management (DTM) systems are used to reduce the negative externalities of congestion, such as air pollution in urban areas. They require and environmental monitoring infrastructures. In this paper we present a prototype low-cost Internet Things (IoT) system for flow Air Quality Index (AQI). The computation flows is based on processing video compressed domain. Only using motion v...

background and purpose: in this study, the air quality index and concentration of particles such as pm10 and pm2.5 were investigated in arak. materials and methods: to determine the concentration of pm10 and pm2.5, 60 samples were collected by laser tsi model 8520 in summer and winter 2012. the collection site was around arak city center. results: during the sampling period, as a matter of pm10...

Abstract The adverse effect of air pollution has always been a problem for human health. presence high level pollutants can cause severe illnesses such as emphysema, chronic obstructive pulmonary disease (COPD), or asthma. Air quality prediction helps us to undertake practical action plans controlling pollution. Quality Index (AQI) reflects the degree concentration in locality. average AQI was ...

To explore the impact of green financial policy on regional economic development level and Air Quality Index (AQI), this paper selected two pilot regions reform to construct a quasi-experiment in Zhejiang Province. The results show that finance can reduce AQI pass parallel trend test placebo test, showing strong stability. Mechanism analysis shows improve environmental quality mainly by increas...
