Abstract
Particulate Matters (PM) is one of the serious problems in Dhaka
metropolitan area. The main causes of particulate matter in Dhaka City include
vehicle emissions, industrial activity, construction dust, continuous
development projects, as well as biomass and garbage burning. In the Dhaka
metropolitan area, the purpose of this study is to monitor the concentration of
particulate matter (PM₁, PM₂.₅, and PM₁₀) based on the different land uses that
are there. Using a portable Air Quality Monitor this research was carried out
in seventy different places within the metropolitan area of Dhaka. It is found
that average concentrations of PM₁, PM₂.₅, and PM₁₀ of 70 places in Dhaka
metropolitan were 153.28, 252.96 and 326.93 µg/m³ respectively. The mean concentration of
PM₂.₅ and PM₁₀ across all land use types was found to be 3.89 and 2.18 times
greater than the National Ambient Air Quality Standards (NAAQS) limit. It is
estimated that the average PM₂.₅/PM₁₀ was 75.45%, PM₁/PM₂.₅ was 62.74%. The
concentrations of all examined parameters within land uses did not change
significantly. Additionally, it figured out that Suvastu Arcade, Elephant Road
was most polluted place with the PM₁, PM₂.₅, and PM₁₀ concentrations of 287.25,
300 and 605.33 µg/m³ respectively which is 4.61 and 4.03 folds higher than
NAAQS level. At last, it has been found that the average concentration of PM₁,
PM₂.₅, and PM₁₀ becomes greater from commercial to residential to mixed to
industrial to sensitive areas.
