Unsafe PM2.5 levels in some areas of Bangkok


BANGKOK – People in Bangkok have recently enjoyed a brief period of cool weather. However, as temperatures steadily rise in the city, members of the public have to be prepared for rising levels of PM2.5 particulate matter in the air due to a high pressure system and low wind speeds. Today (Dec 10), the levels of PM2.5 have exceeded the safe threshold in several areas of Bangkok.

According to the Pollution Control Department’s Air4Thai mobile application, levels of particulate matter 2.5 micrometers and less in diameter (PM2.5) measured 25 to 76 micrograms per cubic meter in Bangkok this morning, with PM 2.5 levels ranging from moderate to good in most areas of the capital.

However, levels of PM2.5 were above the safe threshold of 52 micrograms per cubic meter in a number of districts of Bangkok. They included Din Daeng, Rama IV Road in Pathum Wan, Rama III Road and Charoen Krung in Bang Kho Laem, Charoen Nakhon Road in Khlong San, Phet Kasem Road in Phasee Charoen, Bang Sue, Lak Si and Bang Khen.

The levels of PM2.5 also exceeded the safe threshold in Bangkok’s surrouding areas, namely Muang Nakhon Pathom in Nakhon Pathom province, Pak Kret district in Nonthaburi province, Phra Pradaeng and Muang Samut Prakan districts in Samut Prakan province and Om Noi and Muang Samut Sakhon districts in Samut Sakhon province.

The overall air quality in northern, northeastern, eastern and southern Thailand ranged from moderate to good levels.

Meanwhile, the Meteorological Department has issued a weather report, saying the upper region of Thailand is experiencing cool to cold weather with strong winds. Temperatures range from five to 14 degrees Celsius in the northern and northeastern provinces. Frost is likely on mountain peaks, with temperatures ranging from one to eight degrees Celsius. In the eastern and central regions, including Bangkok, temperatures are around 13 to 21 degrees Celsius. People should be mindful of their health during this period.
