Thanks for the link, geovalin.

Of course(?) they are writing in 'thestar.com.my' just about 'coal-fired' power plants.

Not mentioning it is lignite-fired, considered the dirtiest and cheapest coal which

is very harmful to humans. - More information about the lignite-fired power plant

Hongsa, adjacent to Thailand's Nan Province:  https://en.wikipedia.org/wiki/Hongsa

and about lignite:  https://en.wikipedia.org/wiki/Lignite

There is already a c-f p p near Lampang, Mae Moh and an additional c-f p p near

Tak, Mae Sot. - They might be responsible, at least partially for the northern air pollution.

Of course, they will never be the root cause.

Phrae today between AQI 293 and AQI 322. - As often we don't smell it. 

But the horizon is grey, the air above bright-white milky. - The AQI-Calculator

will not calculate. Too much? - https://www.airnow.gov/aqi/aqi-calculator/

'Nanoparticles' is a bit different.

Ultrafine dust or ultrafine particles (UFP) are usually particles in the air with a diameter between 1 and 100 nanometers (nm). In addition to the PM10 and PM2.5 fractions, the UFP fraction is the smallest particle of fine dust.

Well, I would be happy, if the PM2.5 story would improve.

Perhaps this might be interesting for you?

Yet again , who to believe ?

ventusky.com is a great site. But not always correct. It is important to keep

in mind that the numerical model predicts the atmosphere in simplified form.

Better compare different sites all the time.

This is ChiangRai - Phrae at 18:00 (https://aqicn.org/here) while at  18:46 Lampang,

Phrae and Phayao (https://www.iqair.com/) were in Thailand's Top Ten, believe it or not.

I would prefer released measurements of PM2.5.
