As of 6pm yesterday (7pm Malaysian time), Bangkok’s air quality index (AQI) reading was recorded at 152 on IQAir, a Swiss air quality tracking platform.
An AQI reading of above 100 is considered “unhealthy”, while above 200 is “very unhealthy” and a level beyond 300 is “hazardous”.
The Pollution Control Department said the unhealthy levels of PM2.5 is due to stagnant weather.
