Assessment of Air Quality Parameters at Different Locations of Tangail Sadar Upazila, Tangail

Abstract

The study was conducted to investigate the concentration of PM_2.5, PM₁₀, CH₄, CO₂, CO, SO₂ in the air of Tangail Sadar Upazila, Tangail. In the study area air quality data has been collected from eight sampling stations namely MBSTU campus, Baby stand, Nirala more, New bus stand, Rabna bypass, College gate, Old bus stand, Nogor jalfoi during dry season. The air quality data collected by using Aeroqual S 500 series. The concentrations of PM_2.5, PM₁₀, CH₄, CO₂, CO, SO₂ found in air were ranged from 0.03-0.06, 0.04-0.10, 12.3-36, 919-1238.2, 0.00- 2.61, 0.00-0.48 mg/m³, respectively. The concentration of PM_2.5, PM₁₀, CO, SO₂ that have been found were higher than Bangladesh standard and WHO guideline. Their sources could be the motor vehicles, road dust, coal burning, road construction, open dumping of solid waste in Tangail Sadar Upazila. Appropriate engine design control strategies and maintenance services should be introduced for reducing emission. Efficient solid waste management system should be introduced to control emission from construction sources.
