A malfunctioning air pollution sensor has produced a false reading of PM2.5 dust levels in the atmosphere of Chiang Dao district of Thailand’s northern province of Chiang Mai. It reported 1,358ppm on Thursday, alarming the district’s residents.

 

Atthaphol Charoenchansa, director-general of Pollution Control Department, said today (Saturday) that the actual reading on that day was 9.4ppm, not 1,358ppm as reported in IQAir, a real-time air quality information platform.

 

He said that the department immediately ordered an investigation and sent officials to conduct air quality tests, as well to check data beamed from the satellite and other air quality measurement stations in the northern region, adding that the findings show that the air quality in the northern provinces was within safe limits and no hot spots had been detected on that day.

It's peeing down what's concerning the alarm.

just give it another month or two and it will be real

I've just come back from the Northeast to Prathumthani and one thing I notice different here is that at night around 2am there's a white fog or smog everywhere. It's been cooler so maybe it's that, but I worry about air pollution. We have what I guess is a small trash to energy plant about five kilometers away and some nights its exhaust pollution has made a direct line for our apartment.

 

Around the time Covid hit in 2020, I felt I was hit by what I thought was the PM2.5.  I didn't wear a mask for that pollution and at that time people hadn't started the masks for Covid. Despite living in the same area 20 years, I never was affected by the air pollution that way others claimed to be. I still don't know if it was the 2.5 which got me which was an issue up until Covid became the issue in Thailand. I felt a serious loss of breath for six months after that and still have issues. The masks we wear today make me feel like I can't breath a lot of the time but I wear them. Anyways, just my experience.

 

I hope the air pollution problem isn't as bad as it was in the past.

I hope britman survives another year

Nothing wrong in my app ????

I live a bit further north and considering the amount of rain we have had I cannot believe there would be any pollution.
