Thailand: Smog reaches “danger” level in Bangkok Feb. 14-15 /update 1

Event

On Wednesday, February 14, every Air Quality Index (AQI) reading in the capital Bangkok surged well over the "danger" threshold. Levels of particulate matter of 2.5 microns or smaller (PM2.5) reached between 52 and 75 in different parts of the city.

The Thai Meteorological Department announced on Wednesday that temperatures in Bangkok would drop slightly (by 1-2°C [1-4°F]) and that the lack of wind would increase the level of airborne particulates. Authorities have asked private and public sectors to suspend construction activities.

Context

According to the World Health Organization (WHO), excessive PM2.5 in the air can result in breathing problems, trigger asthma attacks, reduce lung function, and cause lung disease.

Advice

Individuals present in Bangkok are advised to monitor the situation via local media, follow instructions issued by local authorities, and refrain from nonessential outdoor activities when the AQI is elevated. Pollution can be particularly problematic for vulnerable individuals, such as children, seniors, pregnant women, and people suffering from asthma and other respiratory issues. If experiencing breathing difficulties, do not hesitate to seek medical attention, particularly if new symptoms appear (e.g., cough, sore throat, irritated eyes).
