According to measurements taken between 1 and 15 March 2025, by the Department of Environmental Conservation under the Ministry of Natural Resources and Environmental Conservation, the ambient air quality in Yangon Region is generally within acceptable levels.
To assess the ambient air quality across the country, the Department of Environmental Conservation regularly measures air quality parameters at designated sampling points in the Nay Pyi Taw Union Territory, regions, and states. According to measurements taken in March 2025, the air quality in Dagon Township, where the Yangon Region Government Office is located; Kamayut Township, where the International Business Centre is located; and Dagon Myothit (South) Township in Yangon Region is at an acceptable level.
The air quality in townships such as Pobbathiri in the Nay Pyi Taw Council Area, Aungmyaythazan, NyaungU, Kyaukse, PyinOoLwin, and Meiktila in Mandalay Region; Monywa in Sagaing Region; Bago in Bago Region; Pathein in Ayeyawady Region; Myawady and Hpa-an in Kayin State; and Mawlamyine in Mon State is at an acceptable level. The air quality in Patheingyi and Amarapura in Mandalay Region and Kengtung in Shan State is at a level that may affect health.
The air quality in townships such as Thayet in Magway Region, Myeik and Dawei in Taninthayi Region, and Monghsat in Shan State is reported to have acceptable air quality. In addition, the air quality in Monywa in Sagaing Region and Magway in Magway Region is at a level that affects only vulnerable individuals.
Air quality is regularly measured and analyzed using instruments such as the Environmental Perimeter Air Station (EPAS) — Haz-Scanner, Air Quality Monitoring Station (AQM-65), Scentroid (SL-50 Scentinal), Aeroqual (Series 500 Portable Air Quality Monitor), AQMesh (Dust Analyzer – 1941150, Gas Analyzer – 1940150), Portable Beta Attenuation Mass Monitor (BAM 1022), Air Quality Monitoring Station (AQMS), and Continuous Particulate Monitor. Key parameters, such as Particulate Matter 2.5 (PM2.5), Particulate Matter 10 (PM10), Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2), Ozone (O3), and Carbon Monoxide (CO), are also measured.
In addition, the ambient air quality results may vary depending on factors such as air temperature, wind speed, wind direction, humidity, rainfall, vehicle usage, emissions from factories, and the surrounding environment at the measurement site. — ASH/TH
