Abstract
Particulate matter is a major pollutant in Sylhet, and it stems primarily from dust generated by construction sites, unpaved roads, and emissions from vehicles, especially those running on outdated engines. The objective of this study is to monitor the Particulate Matters (PM₁, PM₂.₅, and PM₁₀) concentration based on different land use in Sylhet City Corporation. This study was conducted in 59 locations of Sylhet City Corporation, by using portable Air Quality Monitor. It is found that average concentrations of PM₁, PM₂.₅, and PM₁₀ in Sylhet City Corporation were 59.44, 97 and 124.91 µg/m3 respectively. It is estimated that the average PM2.5/PM10 was 77.55%, PM1/PM2.5 was 63.36%. The average concentration of PM2.5 (97 µg/m3) of different land-use was found higher which 1.49 times higher than the NAAQS level. The concentration of PM in ambient air with respect to land use decreases as follows: mixed area> commercial area > road intersection area > residential area> sensitive area > village area > industrial area. As air pollution extent in Sylhet is relatively higher it is high time to take some mitigation measures to minimize this alarming environmental problem.
