Air quality in Bangkok has improved today (Thursday), but it still poses a threat to health, with 70 areas in the capital reporting PM2.5 dust readings of 56-99 microns between 5am and 7am, according to the Air Quality Information Centre of the Bangkok Metropolitan Administration (BMA).
Of the 70 affected areas, Bueng Kum sub-district recorded the highest level of PM2.5 at 96 microns, which is health threatening.
Other affected areas of Bangkok today include Bang Khen, Chatuchak, Bueng Kum, Min Buri, Prawet, Samphanthawong, Wang Thong Lang, Phra Nakhon, Ban Na, Sathorn, Yannawa, Thawee Wattana, Taling Chan, Bangkok Yai, Nong Khaem, Phasi Charoen and Bang Bon districts.
Two hotspots were detected by a NASA satellite at 1.16pm yesterday in Lam Phak Chi and Arun Amarin sub-districts.
According to the Air Quality Information Centre, air circulation is forecast to improve until Sunday, due to the easterly wind which helps to disperse dust in the atmosphere.
A tropical storm, due to the convergence of a cold front and a hot air mass, is forecast in the north from Sunday until next Tuesday, with strong winds, thunder storms and hail in some areas.
