Bangkok: PM2.5 levels remain a concern in many areas; the public is warned to exercise caution. The deputy government spokesperson reported that the PM2.5 dust situation remains worrying in several areas and warned the public to exercise increased caution and take close care of their health.
According to Thai News Agency, Ms. Lalida Periswiwatana, Deputy Spokesperson for the Prime Minister's Office, revealed a report on the PM2.5 particulate matter situation based on the latest air quality monitoring data. An assessment of the PM2.5 monitoring map shows that many areas of Thailand have particulate matter levels ranging from those beginning to affect health to those at a dangerous level, requiring close monitoring.
The deputy spokesperson stated that several areas in the northeastern region, such as Udon Thani, Khon Kaen, Nakhon Ratchasima provinces and surrounding areas, had PM2.5 levels ranging from approximately 150-180 micrograms per cubic meter, classified as severely affecting health. Meanwhile, in the northern region, including upper Laos, particularly in Chiang Mai, Lampang provinces and the Mekong River basin, PM2.5 levels ranged from approximately 60-130 micrograms per cubic meter, classified as having a moderate to significant health impact.
In the upper central region, PM2.5 levels were found to be in the range of approximately 110-160 micrograms per cubic meter, with many areas experiencing levels that affect health. Meanwhile, in the eastern and upper southern regions, most PM2.5 levels were in the range of approximately 60-90 micrograms per cubic meter, classified as levels that begin to affect health.
Ms. Lalida further stated that, based on academic assessments, the detected particulate matter levels remain several times higher than the World Health Organization (WHO) standard, which sets an annual average of no more than 5 micrograms per cubic meter. These fine particulate matter can penetrate the alveoli in the lungs and enter the bloodstream, affecting the respiratory and cardiovascular systems and increasing the risk of long-term chronic diseases. This situation is consistent with stagnant weather conditions, weak winds, the accumulation of pollutants, and the influence of transboundary haze.
The deputy spokesperson also stated that public health agencies are requesting public cooperation in avoiding outdoor activities, especially in areas where PM2.5 levels exceed 50 micrograms per cubic meter. If it is necessary to go outside, people should wear an N95 or equivalent dust mask and closely monitor their health, especially children, the elderly, pregnant women, and those with underlying medical conditions, who should stay indoors and minimize their exposure to dust as much as possible.
