The time series analysis is utilized to analyze the long-term trends of particulate matter (PM) and ga...Show More
According to the existing air quality forecasting model, this paper proposed an air quality forecasting method based on deep learning. By analyzing forecasting data, monitoring data and meteorological data, a new air quality forecasting model in the region is established. The model fully takes into account the time variability and spatial distribution characteristics of air pollutant concentration...Show More
Air pollution levels have been rising around the world in recent years. Long-term pollution exposure causes a variety of ailments, including lung disease, heart disease, and eye irritation. The term “indoor air quality” refers to the building’s residents' air quality. Physical variables, chemical or gaseous pollutants, and biological factors. Toxic gases are likely to be present in any laboratory ...Show More
The main objective of this study is to determine the more appropriate computational intelligence (CI) model for the prediction of air pollutants in urban areas. In this paper, in order to emphasize the importance of short-term air quality (AQ) prediction, PM2.5 is used as an example to evaluate the concentration of pollutants using a variety of CI methods and tools. According to the data of air qu...Show More
The paper analyzed the three-year (from 2006 to 2008) concentration data of SO2, NO2 and PM10 with routine monitoring in Xi'an, and selected several common statistical distribution models to fit the observational data. The results showed that the most appropriate distribution models representing the daily average concentration of SO2 (0.0514 ± 0.0390 mg/m3, n=1096), NO2 (0.0416 ± 0.0135 mg/m3, n=1...Show More
Air quality models (AQMs) are essential in complex air quality management studies. Due to data limitations, AQMs are occasionally used in developing countries. This study focuses on assessing the impact of thermal power plants on ambient air quality in the Colombo Metropolitan Area (CMA), Sri Lanka, using the AQM for the first ever in Sri Lanka. Concentrations of SO2 and NO2 were measured at 18 sa...Show More
In the midst of the COVID-19 outbreak, India imposed a state-wise lockdown due to which pollution levels in major cities across the nation decrease drastically. The current study used a variety of pollution metrics (PM10, PM2.5, SO2, NO2, CO, O3, and NH3) to reveal geographical air quality patterns before and during the lockdown. The findings revealed that during a lock-down, air quality increases...Show More
The practice of estimating the concentrations of air pollutants in a certain area over a predetermined time frame is known as air quality prediction. As is well known, air pollution harms both the environment and human health as a result of constantly rising urbanization. Predicting air quality is the only approach to stop the negative effects of air pollution. Consequently, the project's abstract...Show More
Air quality influences the life of the living beings that inhabit planet Earth. High levels of air pollutants in ambient air are in fact able to affect human health and also ecosystem integrity. Their monitoring allows for regulating the most appropriate air quality indices and verifying whether they are below the established harmful levels. However, this is a task that requires many physical and ...Show More
Six criteria pollutants were monitored in varied zones of Coimbatore City during a period of one year and correlated with the natural meteorological conditions such as temperature, relative humidity (RH), wind speed and precipitation using SPSS 23. The Spatial distribution analysis was determined by Inverse Distance Weighted (IDW) Interpolation Technique using ArcGIS 10.5. The interpolated values ...Show More
