At certain times in many areas of Thailand, there will be a phenomenon of dense dust covering. This dust will also contain small dust particles called PM2.5. Therefore, knowing the dangers and methods of protecting against PM2.5 dust and putting them into practice will help us be safer from dust and various air pollution.
Understanding “PM2.5 dust”
PM2.5 dust or Particulate matter with diameter of less than 2.5 micron is small dust particles with a size of no more than 2.5 microns. If compared to a human hair, it will be equal to 1 in 25 parts of the diameter of a human hair. สมัคร ufabet This small size causes our nose hairs, which act as dust filters, to be unable to filter it. Dust therefore spreads into the respiratory tract and reaches the innermost layer of the lungs. PM2.5 dust is also a carrier of other substances such as mercury, heavy metals, or other carcinogens.
Where does PM2.5 dust come from?
Dust particles measuring no more than 2.5 microns, or PM2.5 dust, can occur for many reasons, such as:
- Exhaust fumes from vehicles or traffic
- Pollution from industries such as building construction, power generation, or manufacturing industries.
- Open burning, such as burning forests, fields or agricultural areas, and burning garbage.
And even some daily activities contribute to air pollution, such as smoking, burning incense and candles, and cooking with charcoal or firewood.
Risk groups to be aware of
- Patients with respiratory disease
- Patients with cardiovascular disease
- child
- Elderly
- Pregnant women
People in these risk groups should avoid being in areas with high air pollution levels, as they may experience more severe and exacerbated symptoms than the general population.
The severity of PM2.5 dust
Since PM2.5 dust can pass through the filter of nasal hairs and enter the respiratory system to the innermost layer of the lungs, even though exposure to PM2.5 dust does not have an immediate or severe effect on the body, if it is continuously exposed for a long time until it accumulates in the body, it will cause disruption to the functioning of various internal organs, which can adversely affect health, such as respiratory diseases, chronic cardiovascular disease, chronic lung disease, and even lung cancer.
Initial symptoms occur when PM2.5 dust enters the body.
- Irritating and burning eyes
- Cough, sneeze, or a burning nose
- Headache, nausea, vomiting
- Feeling tight in the chest, stuffy, and having difficulty breathing
- Skin irritation
