Moderate air pollution (yellow level) has also been recorded in the northeastern provinces of Thailand, such as Nakhon Phanom, Mukdahan, Yasothon, Nong Khai, and Ubon Ratchathani.

In June of this year, the PCD lowered the threshold at which PM2.5 levels are considered hazardous, from 50 to 37.5 µg/m³.

The department stated that the increase in PM2.5 particle air pollution levels across the country is linked to higher atmospheric pressure. According to forecasts, pollution will remain at the "orange level" for another 1-2 days.

The Ministry of Health recommends monitoring air pollution levels using the Air4Thai app or through the website http://air4thai.pcd.go.th.
