Chiang Mai this afternoon (March 10) became the most air polluted city in the world, according to AirVisual.com.

 

AirVisual reported on its website that Chiang Mai’s air quality index (AQI) today had a PM2.5 level of 239 micrograms per cubic metre on average, much higher than the 100 AQI safety standard. Areas with the highest PM2.5 levels included Chiang Dao district at 445 and Mae Taeng district at 355.

The AQI is a standard that indicates the level of air pollution. Level 0-50 means good air quality, 51-100 means moderate quality, 101-105 will affect sensitive groups, 151-200 is slightly harmful to health, 201-300 is highly harmful and 301-500 means extremely dangerous.

 

The Pollution Control Department reported that air pollution in the North will tend to worsen this week due to the burning of fields and farmlands in neighbouring countries, which has created high levels of particulate matter less than 2.5 microns in diameter, or PM2.5, in the region. The department cited heat signature readings, which have spiked around Tachileik city in Myanmar.

 

Chiang Mai has suffered from air pollution since late January, when the PM2.5 level reached 189 micrograms per cubic metre on January 28 and has continued to climb since.

Chiang Mai, the number 1 retiree destination in the world...at one time.

 

Gross lack of leadership and lack of genuine concern for the health of it's citizens will soon make Chiang Mai the last place retirees will want to go or tourists visit.

 

Let's all go to the Temple and make merit!

I see they have changed the official AQI and now say that 0 to 50 is "Good quality air" !  When we all know that 25 is the maximum safe limit set by the WHO. Thailand setting their own rules as usual. They know better than the rest of the world !

Again blaming neighboring countries instead of taking on own accountability....

 

If citing the Burma border, then why isn’t Chiang Rai #1?

If you look at the wind current maps it appears that Thailand is split down the middle. To the West of of the centerline, wind currents seem to come from Myanmar, East of the line they seem to flow from Vietnam, Laos and Cambodia. It looks as though Chiang Mai catches the pollution from the West whereas Chiang Rai is more impacted by winds from the East. Take a look:

As explained to us by our local headman here in CMai corruption is a big factor re the annual 'burning' 

 

Not going to go into details as I doubt anyone is interested anyway but if anyone is let me know.
