  1. *PM10, particulate matter ≤ 10\(\mu m\) in diameter; PM2.5, particulate matter ≤ 2.5\(\mu m\) in diameter
  2. The IQR was 29.12 µg/m3 for PM10 and 16.68 µg/m3 for PM2.5. The model included temperature, relative humidity, air pressure, sunlight, calendar time, and holidays as adjustment variables
  3. IQR, interquartile range; PM, particulate matter
