Pattaya holds the top spot for the highest PM2.5 health-hazardous dust level as of November 5th, 2023.
The concentration of extra-small particles has surged to 154 micrograms per cubic meter in Pattaya, far above the safety threshold of 50 micrograms per cubic meter, according to the IQAir website on November 5th, 2023.
AQI (Air Quality Index) levels surpassing 100 fall into the “unhealthy” (red) category, while those exceeding 200 are classified as “very unhealthy” (purple). Beyond 300, they are deemed “hazardous.”
The province in Thailand with the highest levels of pollution was Samut Sakhon province. Additionally, areas in Bangkok, Nonthaburi, and Samut Prakan were also noted for elevated levels.
Meanwhile, Thailand ranks 25th globally for air quality, with an average AQI of 75, indicating PM2.5 levels exceeding international standards.
