Air pollution is currently a big problem dangerous to human health. According to a few recent studies, it is discovered that an air dust is even more dangerous than PM2.5, which is Nano dust. So what is Nano dust? What effects does it have on human health?

Dust is actually tiny solid particles in the air. The smaller the dust, the more likely it is to penetrate deeper into the body. Depending on its size that people divide into different categories, ranging from PM 10 (particles with size from 2.5 to 10 micrometers), particles PM 2.5 (size below 2.5 micrometers), … PM is the symbol for Particulate Matter – for solids or liquids mixed in the earth’s atmosphere.
Recently, fine dust monitoring results in Vietnam have discovered PM1.0, also known as Nano dust – Dust with size less than 1 micrometer.
The effects of air pollution very dangerous to human health. But the smaller the dust, the greater the health effects. Therefore, Nano dust can easily overcome all dust barriers of the respiratory system. More dangerous it can affect the structure of human DNA.
Fine particles penetrate into the body, reduce lung function, chronic bronchitis, asthma and lung cancer. At the same time, making the condition worse and possibly fatal.
According to research by World Health Organization WHO and International Cancer Research Agency IARC, fine dust particles from 10M to 2.5M are all considered carcinogens. More dangerous, because dust PM1.0 is small in size, it goes deeper into the human body, passes through cell membranes and can cause even more dangerous effects.
A 2013 study based on nearly 320,000 people in countries in Europe. This study has found that there is no safe level of nano dust exposure. When the PM10 concentration in the air increased to 10 micro grams / m3, the rate of cancer increased by 22%. And MP2.5 is even more deadly when it increases the risk of lung cancer by 36% for every 10 micro gram / m3 increase in air.
Nano dust can penetrate deeply into the pregnant woman’s body, pass to the fetus and cause adverse effects on fetal development at any stage of pregnancy. They are the cause of placental blood poisoning, making the fetus slow to develop. Babies born with low weight, are more likely to suffer from nervous breakdown and autism. In addition, small children and older people with less resistance are also severely affected by this dust.

When Nano dust enters human vascular system, it will form plaque build up in the vessel wall, causing vasculitis. At the same time, reducing the elasticity of blood vessels, increasing the risk of atherosclerosis. Formation of cardiovascular diseases, stroke. Even mocking people.
This is based on research by Taiwan scientists (2012). This study has shown that nano dust can also penetrate deeply and affect the activity of DNA. Increases the risk of genetic mutations or mutations. In addition, some other researches that Nano dust damages human DNA, negatively impacting health and genetic apparatus.
It even contains radioactive substances that are dangerous to humans. Accordingly, the risk of radiation exposure through inhalation or oral inhalation increases if they are attached to agricultural products. According to annual statistics show, Nano dust particles are the cause of 5 million deaths each year globally.
There is no effective way to clean this “super dust” contaminated air. But today’s environmental pollution is increasingly serious. Therefore. Please use PM1.0 prevention to protect your health.
