Threat to Ambient Air Quality Due to Poor Municipal Solid Waste Management: A Case Study in and around Vuasuni Dumping Site, Bhubaneswar, Odisha , India.

Abstract

The objective of this study is to assess the state of air quality near municipal solid waste dumping site of the smart city Bhubaneswar, Odisha,India. Air Quality Index (AQI) in the study area has been calculated by measuring parameters like particulate matter (PM₁₀, PM_2.5), sulphur dioxide (SO₂), oxides of nitrogen (NOx) and carbonmonoxide (CO). Air status from AQI study depicts moderately pollution at dumping site (AQI=51.9). Corelation study shows a strongly direct relation among AQI and PM₁₀ (r=0.964). Regression study reflects PM₁₀ is good at predicting AQI (R²=0.93065, p<0.0001). Multiple linear regression (MLR) study predicts AQI with very less error(rss=0.0003) where PM₁₀, PM_2.5, SO₂, NOx and CO are independent variables. This study also identifies potential sources of pollution and the extent of air pollution. In addition, management strategies have been proposed to minimize the effects of pollutants.
