PM 2.5 dust, today NAWATTRA has a picture of the size to compare the small particles of toxic dust together, including the research of unexpected dangers of toxic dust.
When comparing size and smallness to visualize Dust is 25 times smaller than our hair, about 3 times smaller than red blood cells and fungi ever ……… the term PM stands for Particulate Matter is a small supporter that floats. In the air It is divided according to the size of the larger particles, ie particles no larger than 10 micrometers (PM10) and particles smaller than 2.5 micrometers.
Large dust normally falls to the ground according to the Earth’s gravity. But small dust Will be able to float in the atmosphere for a long time And can bind with other pollutants in the air such as cadmium, mercury, heavy metals, polycyclic aromatic hydrocarbons (PAHs) ………… The World Health Organization has classified PM2.5. In the first group of carcinogens ever (Class 1Carcinogen) allows us to breathe dust. That catches with pollution in the body easily
The one that has a lot of health problems is PM 2.5 dust, which is so small that it cannot be seen with the naked eye. It has to be in a reasonable amount to be noticed as dust and smoke ………. with particles so small that the nose hair cannot be filtered Will be able to penetrate into the body through the respiratory tract Or through the skin hairline……. When entering and causing inflammation Until affecting the occurrence of various diseases that follow Such as respiratory cancer, heart attack, brain atrophy, damaged blood vessels Skin allergic reactions and irritation etc.
A study published in the Journal of the American Medical Association (JAMA) * suggests that long-term exposure to dust can cause plaque in the arteries. And cause inflammation of blood vessels and hardening of the arteries Which, in the end, can lead to cardiovascular disease …………. The scientists in studies estimated that dust pollution increases in the air every 10 micrograms per cubic meter (μg / m3) is related to A 4% increase in all-cause risk, 6% of heart and lung disease, and 8% increase in lung cancer mortality, respectively.
Lung cancer, cardiopulmonary mortality, and long-term exposure to fine particulate air pollution. JAMA. 2002 Mar 6; 287 (9): 1132-41.
The normal mask that we use in the market Therefore can not prevent dust How much into the body You have to use a special mask which is a small particle filtration size, which we call N95.
