The smog in the capital has now reached a dangerous level in many places. The concentrations of particulate matter (PM2,5) have risen far above the safety limit of 50 mg per cubic meter of air.
The situation is particularly worrying on roads with heavy traffic: Intharaphitak Road (72 micrograms of PM2,5 per cubic meter of air), in Bang Na district (61), Wang Thonglang (60), Lat Phrao and Rama IX Road (53) and Phaya Thai Road (52). On Intharaphitak Road and Phaya Thai Road, the concentration of particulate matter has increased further compared to previous measurements.
Residents are advised to wear a mask, but Director General Sunee of the Pollution Control Department says normal masks do not help, only the special KN95 masks provide sufficient protection.
Deputy municipal secretary Suwanna blames the smog mainly on vehicles that run on diesel. In total, the vehicle fleet in Bangkok has 9,7 million vehicles, a quarter of which (2,4 million) run on diesel. The number of vehicles in Bangkok is 4,4 times the capacity of the roads. 500.000 vehicles are added every year.
The municipality sprays the roads that are most polluted with water once a day instead of once a week. No construction is allowed at night. But that's just a drop in the ocean. More stringent measures are being considered, such as in Paris, where cars are allowed to take to the streets every other day. Suwanna thinks that the situation will be better in eleven years' time because all new metro lines will be ready by then.

The smog or fine dust is not only bad in Bangkok in the Isan; a mist of smog in the morning and black snow in the evening and then a little later making charcoal in the village and no one does anything about it, so in the morning and evening inside and keeping everything cozy living in a village but that is Thailand.
That value of 50 is a Thai standard, the World Health Organization (WHO) sets the standard at half that as the maximum. But then people would be over the limit day in and day out, even though the ministry recently announced that the values were 'normal' (yes, normally high) and 'okay'…

Well that is indeed true here in the village in roy ed too.
It's like a competition to see who can make the most smoke.
Early in the morning and around dusk a large haze of blue smoke.
There is also a lot of smog in changmai. It sometimes looks like fog.
Only drastic measures will help, such as a ban on old city buses and old trucks. In addition, a mandatory adjustment of all diesel cars can also do a lot of good, most smoke like a chimney due to poor combustion.
The adequate mouth masks type N95 and FFP2 / FFP3 are now sold out everywhere in Bangkok. Nowhere to be found, this has been several days.
