AQMS Air Quality Monitoring Report for February 2566 presents air quality monitoring data from various areas throughout February 2566, covering measurements of Total Suspended Particulate (TSP), Particulate Matter less than 10 microns (PM10), Sulfur Dioxide (SO2) gas, and Nitrogen Dioxide (NO2) gas.
The 24-hour average measurements of Total Suspended Particulate (TSP) in February 2566 at Tha Kuan, Thoet Thai Muslim, PTT Housing, and Wat Mab Chalood monitoring stations showed that all values measured throughout the month were below Thailand's legal standard of 330 micrograms per cubic meter.
Similarly, for the 24-hour average measurements of Particulate Matter less than 10 microns (PM10) during the same period at all four monitoring stations, all measured values consistently remained below Thailand's legal standard of 120 micrograms per cubic meter.
Regarding Sulfur Dioxide (SO2) gas, the maximum hourly values measured throughout February 2566 at all four monitoring stations were clearly below Thailand's legal standard of 300 parts per billion (ppb).
Similarly, for Nitrogen Dioxide (NO2) gas, the maximum hourly values measured in February 2566 at all four monitoring stations consistently remained below Thailand's legal standard of 170 parts per billion (ppb).
In summary, the air quality in the monitored areas throughout February 2566 for all specified parameters was consistently good and below Thailand's legal standards. Full details are available in the attached file.
