Abstract

Air pollution is gradually becoming a major health concern globally and Nigeria is especially susceptible to air pollution Available data indicates that vehicular traffics, industries, wildfire and biomass burning are significant sources of air pollutants such as Particulate Matter PM, Carbon Monoxide CO, Nitrogen Dioxide , Sulphur Dioxide  and Volatile Organic Compounds VOCs in the air in Lagos State. The aim of this study is to perform geospatial modeling of air pollution around Olusosun and Solous dumpsites in Lagos State. The study analyzes, assesses, and predicts air pollution emission in these dumpsites and examines their possible health impact on residents. Using both ground and satellite-based data, different GIS techniques were used to model this pollution concentration. These methods include Kriging, Regression, and Landfill Gas Emissions Model (LANDGEM) which helps to analyze, model and predict the air pollutant levels around these dumpsite. The study shows a very high concentration of Nitrogen Dioxide (NO2), Total Landfill Gas, and Particulate Matter (PM) in the dumpsites while Carbon Monoxide (CO) and Sulphur Dioxide (SO2) have limited concentration. The Moderate Resolution Imaging Spectroradiometer (MODIS) data shows a trend of increasing concentration of  over the 5 study months due to an increase in the quantity of waste disposal, which shows that high waste disposal is directly proportional to high level of . It can be concluded that the mean concentrations of CO, PM,  and  around major dumpsites mostly exceed the relevant daily WHO Air Quality Guidelines. It is recommended that living farther (more than 15km) away from the dumpsites can reduce the high risk of air pollution and its related diseases for residents. Also, there is need for proper incineration and maintenance of waste to reduce the level of air and other pollutants in and around the dumpsites.
