Bangkok is set to experience increased pollution levels over the weekend as PM2.5 particles hang heavy in the air, exacerbated by cool weather and poor circulation, according to the Pollution Control Department. Unsafe PM2.5 concentrations were recorded in 36 areas across the city, with Nong Khaem district leading the pack at 51.1µg/m³.

 

These fine particulate matters were measured between 19.5µg/m³ and 53.8µg/m³ early this morning. A combination of local climatic conditions and external influences, like the Trami tropical cyclone traversing the South China Sea, is expected to induce more rain next week, which promises to alleviate the pollution. Until then, residents are advised to take precautions as cooler weather conditions and limited air flow are likely to sustain elevated pollution levels.

 

In related weather updates, the Meteorological Department notes a chill in the northern and north-eastern regions, while some southern areas might face heavy rain. Bangkok will see rain covering 10% of its area, offering a brief respite from the worsening air quality.

Bangkok and Chiang Mai have recently emerged as two of the world's top 50 cities facing significant air pollution challenges, as per the latest IQAir data.

 

Early on Friday, Bangkok ranked 13th globally for air pollution with an air quality index (AQI) of 101. Earlier the same day, it even touched the 7th spot. Chiang Mai followed closely behind at 43rd, with an AQI of 66.

 

These figures paint a grim picture for these Thai cities, as they continue their recovery from recent floods, particularly in Chiang Mai, which struggled with overflowing waterways from the Ping River.

 

Currently, Bangkok remains under an 'orange' alert, signalling unhealthy air, while Chiang Mai finds itself in the 'yellow' zone, indicating moderate conditions.

 

Globally, Delhi, India, maintains the highest pollution levels with an AQI of 287. In Southeast Asia, Hanoi, Vietnam ranks 4th, marked by an AQI reading of 174.

 

Specific districts in Bangkok, including Nong Khaem, have alarmingly high pollution levels, with PM2.5 particles registering at 53.1 microgrammes per cubic metre. Sathon and Bangkok Yai also face similar challenges, with PM2.5 levels at 49.8 and 49.3 respectively. The city's average stands at 35.5µg/m³.

 

In a bid to combat these pollution levels, Bangkok's governor, Chadchart Sittipunt, announced via the BMA's Facebook page that measures are underway. These measures focus on curbing emissions from vehicles and construction activities, with an emphasis on regulating construction truck movements, reported Bangkok Post.

 

As these cities navigate the dual challenges of managing air quality and post-flood recovery, strategic interventions are crucial. The combined effects of climate and urban factors underscore the pressing need for comprehensive environmental strategies in the region.
