" Conclusion

The PM 2.5 level has a complex relationship with various factors: number of fires, weather patterns, and traffic. But this analysis confirms the suspicion that many people have — agricultural burning is the root cause of PM 2.5 pollution in Thailand. Burning activities as far as 720 km away from Bangkok, an area which extends into Myanmar, Laos, and Cambodia, can cause air problems in Bangkok. Solving this problem will not be easy. It will require a collaborative international effort among the Southeast Asian countries. "

Usually you don't smell it,

if you see it, it might be haze, mist, early morning fog.

But it is dust. Today a lot of it in our area...

 

 

 

 

Would be interesting to know when the powerplant starts working.

That's why this site is BS : https://www.airvisual.com/thailand/phrae/rong-kwang

 

At the same time that Phrae town has 328 , 25 km further it's only 64 ?? BS. A lot of smoke here in the air , maybe local burning ... I'm not coming out to go see.

Trying to keep the cats in the room .

Most of Thailand in red, more than 150 AQI.

North of Bangkok a bit worse.

 

No good news.

I think the Chinese smog will be arriving soon.

Thailand mostly red, AQI 191 in Chiang Muan - between

Phayao and Nan. Higher PM2.5 levels too in the South:

Phuket(82), Surat Thani(112) and Hat Yai(147), today 11:00.

Phrae 171 

 

Where there is smoke there must be fire...

1) Turn on a good quality air purifier with HEPA filter

 

My Xiaomi purifier seems to be struggling in night mode lately. I have to run it at high for PM to be at acceptable levels.

 

As of now it is hovering at around 35 in night mode. It's a 7sqm bedroom.

 

Is this normal?

Yes it is normal, my room last night was around 35 as well and I live in the bush.

 

It is now at the time of writing this at 33-35 up and down, although the room is big enough for me to feel comfortable 48m2 with 3 metre ceilings, a little cough here and there but I am not struggling to breathe, that said, when I have bronchitis things change of course.

 

I do put on the air purifier before bed as it was around 44-45 last night, an the kids room around 50, so once it gets down to under a reading of 12 off she goes.

 

Is your room sealed, I mean does any air get in that can add to the increase, mine are as sealed as can be, but at the end of the day some air has to get in.

something seems not to be right.

i do not thing your bedroom is only 7 sqm ... 3 x 2.5m??

 

since a few months i am using air purifiers, my aim (for the bedrooms) is

to be under 10 µg/m3 !

Thailand-News today:

Bangkok - live webcam:

https://www.skylinewebcams.com/en/webcam/thailand/central-thailand/bangkok/bangkok-crossroads.html

AQI Phrae 171 - most parts up north 150 - 180.    

Chiang Muan high again(199). - Why?                             

Saraburi high too(257). - Why?   -   At 11:00 down to 71.

Na Phralan PoliceStation

 

    

                 

By the way - AQI 150 corresponds to 55.4 ug/m3

                         180             "          111.6 ug/m3

A little help with ug/m3 and AQI     

My monitor shows 29, so this should be AQI 87.

Below 20 ug/m3 would be nice. (An old wooden house is not to insulate.)

Above 55 ug/m3: not healthy.

More information in the attached Excel paper. It's a trial version.

Thanks, motdaeng

 

' Small particulate pollution has health impacts even at very low concentrations – indeed no threshold has been identified below which no damage to health is observed. Therefore, the WHO 2005 guideline limits aimed to achieve the lowest concentrations of PM possible. '

[https://www.who.int/news-room/fact-sheets/detail/ambient-(outdoor)-air-quality-and-health]

 

I would be happy (and satisfied) with 10 μg/m³ 24-hour mean. But this is an illusion.

 

By the way, I'm not worried about myself. - I think of the little children, the elderly and the frail and all those people who cannot or can never afford to buy an air purifier.

Ignorance and arrogance might be a minor problem. I don't know.

[Yom]

Feb 7

 

Phrae AQI 161 - that means 75 μg/m³ .

The North 'Unhealthy'.

Bangkok and other places in Thailand 'Unhealthy' respectively

'Unhealthy for sensitive groups'.

Sorry, Surat Thani 'moderate' (AQI 85) and Phuket AQI 55.

But it's much too late.

 

Of nine northern provinces, eight have been declared as strict burn-free areas.

1 Chiang Mai has forbidden burning from January 10 to April 30.

2 Phrae has announced a strict ban on burning from February 1 to April 30.

 

3 Nan province has banned burning from February 15 to April 15.

4. Phayao, Tak, Lamphun, and Lampang provinces have been declared absolute no-burning areas from March 1 to April 30.

5 Mae Hong Son is strictly forbidding fires from March 15 to April 30.

Chiang Rai is monitoring the trend of disaster situations to issue guidelines on no-burn zones later.
