Chiang Mai was once again the world's most polluted city, with air quality level at 346, the AirVisual application reported at 9.58am on Friday (March 20).

 

Dust particles smaller than 2.5 microns in diameter ( PM2.5), measured 295.7 micrograms per cubic metre.

 

The province was followed by Bangladesh capital Dhaka and the Pakistani city of Lahore, with the air quality levels at 214 and 204 respectively.

 

According to the Air Quality Index, a reading between 0 to 50 is healthy, 51 to 100 is moderate, 101 to 150 is unhealthy for sensitive groups, 151 to 200 is unhealthy, 201 to 300 is very unhealthy, and 301 to 500 is dangerous.

Last week they were number 1 with score around 240 I think. Beat #2 by around 50. This new score is like if I raced against Usain Bolt. Have to check some more trucks, I reckon (kidding)

The air is so much better here in Chiang Rai: ‘only’ 301 today at. 13.00h. Was 404 a couple of hours ago.........

Yes, that's actually good according to Thai standards and a great time to get outside and play football with the kids. ???? The health minister has everything under control. Enjoy...????

The governor must be proud of his achievement.

After February 28 Chiang Mai has been ranked n:o 1 on 13 days of total 22 as the worst polluted city in the World.image.png.151670d4a0c1eff05dfa954b208c00c6.png

Congratulations all round to the Governor and those all the way to the very top in charge of Thailand.

 

A record unlikely to be surpassed -until next year!

I am sure Lampang is second but why are more people worried about covid19 than lung damage in this area?

Which 'people' do you mean?

 

The Thai Government is very evidently not concerned enough about (most of) the nation's poor air quality to do anything about it. The causes within Thailand are obvious. And there is no will to tackle the issue from a regional perspective either.

 

If by 'people' you mean expats, it seems that many are more concerned with scoring cheap points about those choosing to live in Chiang Mai, than about the larger issue. Some are simply not aware that air pollution affects pretty much the whole of the north and north-east regions of Thailand and extends further south somewhat too.

 

In all of 2019 for example Chiang Mai had an average 32.3 PM2.5 and was rated unhealthy or unhealthy for certain groups in three months. Lampang, which you mention, had an avg 33.1 (worse than Chiang Mai) and bad for five months.

 

Korat, the worst, at 42.2 avg and bad for four months.

 

Khon Kaen 36.4 avg and bad for five months.

 

Sukhothai 34.6 avg and bad for five months.

 

Ratchaburi 29.5 avg and bad for three months.

 

Chonburi 19.5 and bad for two months.

 

We should all rally together to condemn the Thai authorities, not each other.

Nope, beat ya today ...500 @ 8am(CM city ranking 1) ,157 @ noon , 105 @ 4pm (CM city ranking 41), 144@ 8pm (CM city ranking 26).

These numbers are from out my backdoor in Mae Rim.

The average daily high/low readings for CM from AirVisual ,over the same time periods ,were 364 to 73.

We expected a spike in the PM2.5 from a massive forest fire in the National Park west of the city that burned for 3-days before they got it under control.

Otherwise,its been the nice afternoon winds that have been moving the air along.
