Air Quality Monitor

ESS has installed an air quality monitor to measure PM 2.5 particulates as an indication of the air quality at the IER institute, Dong Hoa Commune, Di An, Binh Duong.

The U.S. Environmental Protection Agency (EPA) has developed a formula to convert PM 2.5 readings into an air quality index (AQI) value that can help inform health-related decisions. Meanings of AQI numerical values can be seen in the chart below. For more information on AQI and how it is calculated please click here.

For more details on air quality in HCMC, Hanoi, and around the Asian region, please follow the link to the Environmental Protection Agency’s Air Now website. AQI can be observed either by clicking on the location on the map, or by selecting a city in the “Select a City” option on the upper right part of the page. The page provides AQI over the last 24 -hour period in the Region as well as pollutant concentration and a downloadable historical document. Other links in Vietnam: , Hanoi CEM Station.

Please note that citywide analysis cannot be done with data from a single monitor. This data provides an accurate measure of the air quality in the section of Dong Hoa Commune, Di An, Binh Duong at the IER institute.
