Exploring Variations of PM_2.5 and PM₁₀ Concentrations in Educational Institutions of Dhaka South City Corporation

Dhaka is being called the dustiest city in Bangladesh. In Dhaka South City Corporation, almost all of the educational institutions are built on the side of the main road. This study aims to monitor the Particulate Matters (PM_2.5 and PM₁₀) concentration based on Educational institutions in Dhaka South City Corporation, Dhaka, Bangladesh. This study was conducted in 37 locations of Dhaka metropolitan, by using Aeroqual S500 Portbale Air Quality Monitor. It was found that average concentrations of PM_2.5 and PM₁₀ in 37 places in the study area were 68.82 and 113.95 µg/m³ respectively. The average concentration of PM_2.5 and PM₁₀ of all the zones was found more than one time higher than the Bangladesh National Air Quality Standard standard level. It is estimated that the average PM_2.5/PM₁₀ was 60.41%. It also revealed that the concentrations of PM_2.5 may change significantly between and within the land uses as the P values are less than 0.05. The outcome of this research is arranged in descending order based on the average concentration of PM_2.5 which follows as Zone-5 (Chak Bazar, Bangshal, Kotwali) > Zone-2 (Dhanmondi) > Zone-6 (Sutrapur, Gendaria, Jatra Bari) > Zone-3 (Ramna, Shahbagh) > Zone-1 (Hazaribagh) > Zone-4 (Lalbagh, New Market) > Zone-7 (Kadamtali).
