Bangkok: Strong winds have temporarily alleviated PM2.5 dust levels in Bangkok, but authorities warn of worsening conditions later this month. The Bangkok governor closely monitored air quality at the start of the week, with schools under the Bangkok Metropolitan Administration (BMA) remaining open.
According to Thai News Agency, Mr. Chadchart Sittipunt, the Governor of Bangkok, observed the PM2.5 dust situation early Monday at the Bangkok Air Quality Information Center in Din Daeng District. He noted that the strong winds had shifted from the east and northeast, carrying away accumulated dust and improving air quality from "red" to "yellow and orange" levels. The governor emphasized that the improvement was anticipated last week and reassured that 437 BMA schools were operational but remained under observation.
Governor Sittipunt warned that while air quality was expected to remain stable for the next two days, conditions could deteriorate on January 29-30, 2025. He expressed concern about ongoing burning activities in neighboring countries to the east, which could impact Bangkok if wind directions change unfavorably.
He also highlighted the Air BKK application, where residents can check air quality. The app displays the average PM2.5 levels over 24 hours to provide a consistent reporting standard, given the fluctuations in dust values.
Regarding vehicle emissions, the governor mentioned that officials would continue unannounced inspections of buses for black smoke emissions. While inspections occur six days a week, legal action requires the involvement of the Department of Land Transport. Currently, Bangkok's authority is limited to vehicles with four wheels, and officials can only request repairs within 30 days for offending vehicles. Governor Sittipunt noted efforts to expand these legal powers.
