"ฝุ่นละออง PM2.5 คืออะไร และต้องตื่นกลัวกันขนาดไหน"
ว่าจะโพสต์จะโพสต์เรื่อง "ฝุ่น PM2.5" นี้หลายทีแล้ว แต่ยังไม่มีเวลาซะที แถมข้อมูลก็มีออกมากันเยอะแยะหลายแหล่ง เพียงแต่รู้สึกว่าไม่ค่อยมีใครสรุปให้ชัดๆ ว่ามันคืออะไร และต้องระวังกันแค่ไหน เลยเอามาลองเขียนแบบสรุปเป็นข้อๆ นะครับ
1. ฝุ่นละออง PM 2.5 (particle matter smaller than 2.5 micron) คือ ฝุ่นละอองที่มีขนาดเล็กมากๆๆๆ ตามองไม่เห็น คือเล็กกว่า 2.5 ไมครอน (ไมโครเมตร) หรือเล็กกว่า 3% ของเส้นผ่านศูนย์กลางเส้นผมเสียอีก .. ในเมือ...
Continue Reading"What is the dust of PM2. 5 and how scared we have to be"
I was going to post this "PM2. 5 dust" so many times, but I don't have time. There are plenty of information. I just feel like I don't have a lot of people to conclude what it is and how careful. Let's try to write in summary.
1. Dust. PM 2.5 (particle matter smaller than 2.5 micron) is a very small dust. It is smaller than 2.5 Micron (Micron) or smaller than 3 % smaller than 3 % Hair diameter.. in the major city is the main cause of engine and from construction (not from burning grass burning straw)
2. Really. Dust. Both size. PM 2.5 and larger ones.
It's all up to air pollution and it's an important problem of the big city. As the clip is seen dust floating everywhere at "Lumpini Park" that should be larger than 50 Micron dust that I can see... but The smaller the dust, instead of falling to the ground, the faster it's usually hanging in the air and makes it harder to be a healthier problem.
3. Dust PM 2.5 is clearly dangerous for health because it is very small. It can pass the respiratory to the lungs and create problems with blood vessels. (those with large ones are often trapped from nose hair and too. Slime and hair on the respiratory channel) and will increase the risk of heart disease and respiratory disease because it can go through the capillaries that nurture all parts of the body, including brain and heart disease, heart disease, etc. Even. The fetus that mother experiences PM2. 5 particles will make children when they grow up, there is a chance to risk of such diseases and it also have the intellectual level of children for life.
4. In Bangkok, the dust level. PM 2.5 during January-February, there are higher than the benchmark (50 micrograms / cubic meters) in many areas, especially along the big roadside with traffic and constructions such as Rama 4 Road, Ladprao Road, Phayathai Road, Inthak Road (see the latest information today at https://www.facebook.com/PCD.go.th/photos/a.536405553109503.1073741834.174094709340591/1609515919131789/?type=3&theater)
5. However, PM2. 5 dust level is not higher than this benchmark is not high as critical as there is news. It is caused by some websites to calculated and compare to foreign standards which is not the right way.
6. Dust situation. PM 2.5 has been many years, but this year has become a lot of campaign because it has come quite faster than the past year (since January) and quite a few months... PM 2.5 dust will be more during the season from winter to summer, such as mid-February, which often fog (steam) occurs), causing the air to turn off. The sun won't reach the ground. The energy to push the energy to float higher to accumulate in The air is on the ground.
7. Therefore, PM2. 5 Dust Surveillance by ourselves. In addition to avoid being near the big roadside area or much construction area, it can still monitor daily numbers from the department of pollution control (https://www.facebook.com/PCD.go.th/) including the Notice that day when the weather is calm. There is a high air humidity (steam) thick or not because there will be a lot of dust accumulation. PM 2.5... or if there is thunderstorms happen that day, the amount of dust in the air. Will be diluted
8. How much dust do we have to be afraid of PM 2.5? If you are a person in the risk of health problems such as respiratory disease or cardiovascular disease, you should avoid getting into high-standard, such as roadside... If you can stay indoors. There is more safe or if you need to go out, you should wear N95 hygienic mask... As for the general health people still don't have to be that scared unless they have to live or work in random areas regularly to wear protective masks. Too much too.
9. Hygienic mask that can prevent N95 dust. It must be a resolution of fibers high enough to filter small dust. Size 2.5 Micron. Like N95 mask that is sold. It will filter the particles. Size 0.3 Micron. Up to 95 % (the source of N95) is suitable to use... As for those who are sold in addition to filter, it is not detailed enough. It is not attached to the face. The air can still pass in and out. Easy to be easy.
10. At the end of this month, the dust situation. PM 2.5 will be better. However, small and large dust is still harmful to health, so we should help reduce the cause of dust, such as reducing the use of construction areas and The car that transporting construction materials to the Midwest, including Bangkok. I should take more vacuum and spray water on the road.
