In view of pollution prediction modeling, the study adopts homogenous (random forest, bagging, and additive regression) and heterogeneous (voting) ensemble classifiers to predict the atmospheric concentration of Sulphur dioxide. For model validation, results were compared against widely known single base classifiers such as support vector machine, multilayer perceptron, linear regression and re...

The impact of air pollution on human health is becoming increasingly severe, and economic losses are a significant impediment to social development. This paper investigates the pollutants respiratory system its action mechanism by using information inpatients with diseases from two IIIA (highest) hospitals in Wuhan 2015 2019, pollutants, meteorological data, as well relevant demographic data Ch...

The chemical composition of the earth’s atmosphere has been an area of general research interest for many decades.1 However, increased attention to a number of environmental issues has fostered a more detailed focus in recent years. These environmental drivers include such topics as (i) the destruction of stratospheric ozone via photochemical cycles involving industrial halocarbons and their re...

The height of mechanical mixing layer is one of the parameter of the safety analysis report of any industrial (nuclear) facility due to its relation to the dispersion factor of pollutants. It can provide information about lower atmospheric dispersion, which is usually used to study the pollutants released from nuclear facility, risk analysis and emergency planning. Mixing layer height is diffic...

China faces unprecedented air pollution today. In this study, a database (SO2, NO2, CO, O3, PM2.5 (particulate matter with aerodynamic diameter less than 2.5 μm), and PM10 (particulate matter with aerodynamic diameter less than 10 μm) was developed from recordings in 188 cities across China in 2014 and 2015 to explore the spatial-temporal characteristics, relationships among atmospheric contami...
