Levels of ultra-fine dust, known as PM2.5, have reached moderate or unhealthy levels in recent days in certain areas of Bangkok and several other provinces, as reported by the Ministry of Public Health. The ministry advises people, especially those with chronic diseases, to check the air quality before leaving their homes or engaging in outdoor activities.
Fine-dust pollution, primarily attributed to crop burning during the cool season, is a seasonal phenomenon. Vehicle emissions also contribute significantly to this issue. The Ministry of Public Health, under the guidance of Dr. Opas Karnkawinpong, the permanent secretary for public health, monitors PM2.5 readings and issues health warnings as necessary.
According to the Pollution Control Department’s air quality website, PM2.5 levels in certain provinces, particularly in the Northeast (e.g., Nakhon Phanom, Mukdahan, Yasothon, Nong Khai, and Ubon Ratchathani), are now at the moderate (yellow) or unhealthy (orange) level. Unhealthy levels have also been reported in various areas of Bangkok, including Kanchanaphisek Road in Bang Khun Thian district, Din Daeng Road in Din Daeng, Khlong Kum area in Bueng Kum, Charan Sanitwong Road in Bang Phlat, Thung Wat Don area in Sathon, and Charoen Nakhon Road in Khlong San district.
Dr. Opas emphasized the importance of checking PM2.5 levels using the Air4Thai mobile application or visiting the Pollution Control Department’s Air4Thai website before going outside. Another resource for assessing air quality is https://pm25gistda.or.th. The following color-coded scale is provided:
Blue (very good): No health risk.
Green (moderate): No health risk.
Yellow (unhealthy): People with respiratory disorders should avoid outdoor exercise, while children and the elderly should limit their time outdoors.
Orange (very unhealthy): People with respiratory tract disorders should avoid outdoor activities, and children and the elderly should restrict their outdoor time.
Red (hazardous): Outdoor exercise should be avoided, and individuals with respiratory tract disorders should stay indoors.
It is essential for everyone to stay informed about the air quality and take necessary precautions accordingly.
