Air quality today
The air quality in Map Ta Phut is classified as USG according to the latest assessment. The primary pollutant identified is PM2.5, with a measured concentration of 48.1 µg/m³. In addition, PM10 levels were recorded at 94.0 µg/m³ based on two valid measurements.
Data are shown via OpenAQ and reflect the current conditions for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes
The air‑quality record for Map Ta Phut currently draws on three monitoring stations that together provide data for six pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). The most recent observations are from early February 2026 for the two particulate‑matter series, while the latest CO reading dates back to mid‑January 2024, NO₂ to May 2022, O₃ to May 2025 and SO₂ to late June 2025. This mix of timestamps means that the freshest data are only a few days old for PM10 and PM2.5, whereas the other gases rely on measurements that are several months or even years old.
Across the three stations the recorded values show a wide spread. CO has been observed from as low as 0.22 ppm up to 6.0 ppm, with a median around 0.83 ppm; NO₂ ranges between 0 and 0.017 ppm, centering near 0.004 ppm; O₃ varies from 0.007 to 0.028 ppm, typically about 0.019 ppm. Particulate matter shows higher concentrations: PM10 values sit between 19 and 94 µg/m³ with a median of 27 µg/m³, while PM2.5 spans 8 to 48.1 µg/m³ and averages roughly 21 µg/m³. SO₂ is the least variable, recorded from 0 up to 0.081 ppm, median 0.0015 ppm.
Because many of the gas‑type readings are classified as “old data” and a substantial portion of rows (18) lack recent timestamps, the dataset does not capture current short‑term fluctuations for those pollutants. Consequently, while the particulate‑matter figures reflect conditions within the past week, the broader picture for CO, NO₂, O₃ and SO₂ may be outdated, and actual air quality can differ across neighborhoods and times of day.

Data notes
The data shown reflects two valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 21:00 UTC. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Map Ta Phut.
