CM air pollution not so bad

That is saying it perfectly. During burning offseason, it is just added to the normal amount and just thinking about that is not good. The burning is not good but I think the massive increase in traffic compounds the problem a lot. Of course, we have village people burning off their rubbish as well at times but that is not the main cause. I mean, when they burn the mountains off in Lumphun, they do it so they can go collect mushrooms after the burn-off. Many of those fires are started by locals so they can collect mushrooms later to sell. In many cases, it comes down to monetary gain. 

 

Overall in Thailand, open burning is by far the largest source of PM2.5 air pollution -- more than transportation, industry and electrical generation combined.

So transportation is bad for you but open burning in the PM2.5 scale is just dire? Is that correct?

 

 

I think I agree with what you're saying... Except, transportation per se isn't "bad for you."  What's bad is vehicles (diesel! and others) that aren't equipped with modern technology to prevent or limit a lot of harmful exhaust pipe pollution.

Thanks for the detailed information. I am learning something from it. What I am seeing in smoke coming out the back of these Red Cars, sitting around for hours at a time in the intersections of Nimmim and the like, cannot be good for the locals living in close proximity to these areas. I have several farang friends that are always sniffing or have allergy problems and they live practically on the roads in Condos in this area. I believe it has got to have something to do with the pollution as they have told me they never had such problems before.

 

I am in San Kamphaeng area and after the burnoff, my air purifiers all need changing of filters as they are just black and our area does not get that high in PM 2.5. I have my purifiers running 24/7 and replace my filters every 4 months but they are never really as dark or dirty as Feb-March.

Total cop out from a Thai apologist-as usual.
 
It is ALWAYS somebody else.
 
Whilst they sit on top of their mountains of garbage and their polluted seas and moan and moan "but we are too poor.."
 
 
*eye-roll, sigh* how am I apologizing for Thailand? I am politely ridiculing the Thai government and academics.

But I am also trying to focus people on the truth - if US, PRC and India do not reverse course now, we are all stuffed, including Thailand.

I doubt any TV regulars will act on ANY of the chatter posted on TV, but if our readers were to take action on ONE thing in their lifetimes, it should be this problem.

In 2008 I sat on a hilltop in China, about 5 hours drive West of Shanghai. We were having a tea break and I walked up to the top of this big hill to have a look at the surrounding Countryside. Rice fields were everywhere, yet I could not get over how much pollution I saw in the air. My business counterpart said to me this was a huge problem and just by looking at the fact I could not see the skyline on a very clear day, he was right. This particular vision of that day stuck with me for the rest of my life.

 

I often wonder at times, what the outlook from that hill is like today. The pollution I saw that day far outweighed the worst I have seen in here during burnoff season and I was told, this was 'normal'. Pretty sad state of affairs is all I can say.

There are multiple sources of AQI data out there... The Thai government (Pollution Control District) has a website for it, there's AQICN.org, and then there's sites that gather and report private sensor data.

 

In looking at any data, you want to make sure it's reporting at least PM2.5 based AQI values. In the past, in a lot of areas, the Thai government didn't have PM2.5 sensors, so their data was only for PM10, and so the readings and warning levels were misleadingly low.

 

Based on comparing its data with my own PM2.5 readings at home, the AQICN.org website data for PM2.5 is pretty reliable most of the time. And if they're getting readings that are oddball for some reason, their system will actually omit that sensor and its data reporting until it gets straightened out.

 

Also, you need to be aware that the Thai government uses a different AQI scale than the U.S. and much of the rest of the world, that tends to have higher threshhold levels. The Thai PCD reports AQI values using the Thai government's scale. The AQICN.org site and others typically use the U.S. EPA AQI scale, which is probably the defacto standard to use and pay attention to.

 

Any way you cut it, however, the bottom line is that pretty much every year, from say December until March or so, the air quality typically is very bad (into the red / unhealthy levels) in BKK, CM and elsewhere.

 

 

PM10 is always higher than PM2.5. How could the Thai govs readings be lower? Or maybe you mean just the warning levels. Higher readings but also much higher warning levels.

As you say, the air is much worse close to the mountain.  I think that being wedged up against Doi Suthep has something to do with it also.  I found that when I lived there, the air quality was at its absolute worst late at night (2am) as the air cooled and the accompanying pollution settled with it.

 

This picture was taken from a condo west of canal road (on Huay Kaew) in March of 2014 (peak burning season) and the trees that are disappearing into the smoke are only 200m from the balcony.

 Different individual pollutants have different scales of actual readings (micrograms or other) that are considered good / moderate / unhealthy for some / unhealthy for all. So those individual pollutant levels aren't the ones to focus on, because they're not standardized.

 

The advantage of the AQI scale (at least the U.S. version) is that it incorporates those different threshold danger levels into the AQI formula for each pollutant, so that good or moderate or unhealthy AQI levels mean the same thing, no matter what pollutant.

 

But in reality, in Thailand most of the time, the one pollutant with the highest AQI levels is invariably PM2.5. And it's the highest individual pollutant AQI that sets the overall AQI level for that hour or day. So pretty much all of the time, the overall AQI and the PM2.5 AQI in Thailand are going to be the same.

 

Re your comment above, however, the Thai Pollution Control District has its own AQI scale that's unique to Thailand, and different than the generally de facto U.S. EPA AQI scale used elsewhere. So if you're looking at the Thai PCD site or any other sites that uses their AQI data, you're likely to see more yellow or orange colored readings, when the other non-Thai sites like AQICN.org will be showing you red for Thailand.

I don't think you get what I mean. I mean PM10 is particles smaller than 10 micrometers. This will include particles which are detected by PM2.5 since that's means smaller than 2.5 micrometers. So if PM2.5 is higher than PM10 then something is broken. So I don't mean about the different scales.

Ah I see now that it might be confusing since most websites lists PM10 or PM2.5 AQI and not the raw particle data.

I always deal with the raw data.

It depends on if you're talking about raw microgram readings of PM2.5 or PM10, or, the AQI readings for those two substances.

 

When I look at the Thai PCD website that shows realtime values for both PM2.5 and PM10 in micrograms, the raw numbers of micrograms per cubic meter of PM10 are always higher than the PM2.5 microgram readings, as you'd expect, because the PM10 measurement is a broader one including more stuff.

But, the AQI values for PM2.5 are going to be higher than those for PM10 typically, because each pollutant has its own individual formula for converting micrograms into AQI, based on the individual health risk characteristics of each pollutant. And PM2.5 has higher risk issues than PM10 because it can enter the body more easily than the larger particles.

Yeah

 

I added AQI on my page (south phuket) now http://slim.keff.org/air/

The raw data of micrograms are NOT comparable from one pollutant to another.

 

That's why they developed the AQI, which is a way of standardizing the publicly reported values across a range of different pollutants with different health risk characteristics.

This is the real joke The local government says it is going to wet the roads down and tell construction companies to reduce dust because this is a major cause of air pollution. Do the locals really swallow this and accept this is what is happening or should the local government take the bull by the horns own up to being totally irresponsible for the bad air and not doing anything about it and start to clean it up. For starters start levying huge fines on any factory or local business that is polluting including a business that is burning rubbish.  Set standard emissions factories are allowed to have. Start regulating and forcing motorcycle manufactures to lower emissions on upcoming new models. Sure they will scream and yell they cannot do it Fact is the automakers did the same but guess what they lowered emissions. Start fining people that do not turn off engines when they are parked.

Street vendors are not allowed to create smoke while cooking  There are systems that can trap the smoke particles. And lastly, make a serious effort to start to clean up the pollution. Build some giant air cleaners. The same as China is building https://www.nature.com/articles/d41586-018-02704-9

You can also engage the University Students Run a contest on who can come up with a novel inexpensive way to clear the air of pollutants

Watch the students get involved and see how fast ideas are created

 

Its time the governments started to take the pollution problems in Thailand seriously If they do not then at some point the tourist trade will dry up and the tourists will start to go to countries that are cleaner

Great news, my three kids now have half-black lung!!!  They will all have miserable lives.... but it could be worse.

 

I also just got food poisoning, but not as bad as some people in Azeraaserbakastan.  

 

Plus I only got hit by one car today, not ten.  

 

everyone is soo nice to me, and i love the 10 baht soup.   great life....

I am on the border of Myanmar, and after hiking 10 kms to get the proper ingredients, I give them to a lady by the river.  She let's me use her fire, while I provide my bowl and soup.  She only charges me 10 baht.

 

I guess you could buy noodles in 711 for like 8 baht and make soup yourself.  LOL.

 

it's possible!! 

 

yesterday I saved 11 baht, but got black lung.

AQICN.org has plenty of good PM2.5 data for CM and areas around there. And the U.S. EPA AQI scale they use is a better one than the Thai version, which tends to understate the pollution threat because the Thai government's own pollution standards are lower than elsewhere.
