The level of PM2.5 dust in 21 northern and north-eastern provinces in the past 24 hours exceeded Thailand’s 50-micron safety level, with the PM2.5 in northern provinces being measured from 37 microns to 459 microns, according to the Centre for Air Pollution Mitigation reported at 7am today (Sunday).
The air quality in the rest of the country is, however, within safety limits, including Bangkok and its suburbs, where it was measured from 16-46 microns in the past 24 hours.
The 21 northern and north-eastern provinces, where air quality is poor and poses a health threat today, are Chiang Rai, Chiang Mai, Nan, Mae Hong Son, Phayao, Lamphun, Lampang, Phrae, Uttaradit, Sukhothai, Phitsanuloke, Tak, Kamphaeng Phet, Phichit, Phetchabun, Bueng Kan, Nong Khai, Loei, Nakhon Phanom, Mukdahan and Ubon Ratchathani.
In Mae Sai district of Chiang Rai, people there have put up signs in public places asking for urgent help to reduce the air pollution, mainly caused by man-made forest fires.
The level of PM2.5 in the six north-eastern provinces was measured at between 32-166 microns.
Those living in the “red zones” in northern and north-eastern provinces are advised to avoid outdoor activities and wear protective gear, such face masks, and consult a doctor if they develop symptoms related to air pollution.
Members of the public can closely follow the air pollution situation through Air4Thai.com and airbkk.com applications, Air4Thai and AirBKK.
