After the storms, weather pollution follows in Thailand.

According to the most recent data from Swiss-based IQAir, Bangkok and Chiang Mai are among the top 50 towns worldwide for little dust particle pollution. &nbsp,

As of 10.25am on Friday, the Thai capital ranked 13th with an air quality index ( AQI ) of 101, despite having briefly been ranked 7th earlier in the day. With a 66 AQI, Chiang Mai was 43rd.

Bangkok was still in the orange area for air quality, which indicates a more favorable situation.

Delhi, India, held the position of the most polluted capital worldwide, with an AQI of 287. Vietnam’s Hanoi in Southeast Asia was ranked fourth worst with an indicator of 174.

Air quality monitoring generally focuses on big cities.

In Bangkok, the highest levels of particulate matter 2.5 micrometres or less in diameter ( PM2.5 ) were found in Nong Khaem district, recording 53.1 microgrammes per cubic metre, followed by Sathon ( 49.8 ), Bangkok Yai ( 49.3 ), Bang Bon ( 47.9 ) and Phasi Charoen ( 45.3 ). The city’s common pollutant levels stood at 35.5µg/m³.

Due to heavy rain and rising water rates in the Ping River, Chiang Mai is still recovering from serious storms that had severely hampered daily activities. Bangkok appears to be free of inundation, though the Royal Irrigation Department reported that water degrees in critical areas are already below emergency rates.

” When the weather subsides, sand results”, Bangkok government Chadchart Sittipunt said on the BMA’s Instagram page on Friday.

According to Mr. Chadchart, City Hall is taking steps to reduce pollution from development vehicles and construction work.
