The BLCP Power Station's ambient air quality report for September 2021 presents the measurement results for 4 types of air quality parameters: Total Suspended Particulates (TSP), Particulate Matter less than 10 microns (PM10), Sulfur Dioxide (SO2), and Nitrogen Dioxide (NO2). Measurements were conducted at 4 locations: Wat Takuan, Trok Thai Muslim, PTT Housing, and Wat Mab Chalood.
The 24-hour average measurement results for Total Suspended Particulates (TSP) and Particulate Matter less than 10 microns (PM10) throughout September 2021 consistently showed values at all monitoring stations to be below Thailand's legal standard limits. The standard limit for TSP is 330 micrograms per cubic meter, and for PM10 is 120 micrograms per cubic meter.
Similarly, the hourly maximum measurement results for Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2) in September 2021 also indicated that the values at all monitoring stations were below Thailand's legal standard limits. The standard limit for SO2 is 300 ppb, and for NO2 is 170 ppb.
In summary, the ambient air quality around BLCP Power Station in September 2021 for all measured parameters was within the standard limits stipulated by Thai law. Full details are available in the attached file.
