Where there is smoke there must be fire...

TH-North a bit better, BKK remains mostly red.

But other parts of the world today, better or not? - all same scale

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.

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

                         180             "          111.6 ug/m3

The wind blew it away, at least a bit.

Where the children of tomorrow dream away in the wind of change?

A little help with ug/m3 and AQI      image.png.1bb4d80d56c7df641f582e537eaf2956.png

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.

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.

https://forum.thaivisa.com/topic/1146987-strict-no-burn-zone-measures-to-be-implemented-in-north/#comments

 

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.
