When wearing a thin dust mask, you should focus more on your nose than on your mouth. National researchers have been able to trace the pathways of fine dust in the body, but it turns out that fine coromancine dust is much more dangerous than the mouth.

Researchers administer fine dust to experimental rats in two ways.
Once injected through the rat's mouth to the esophagus and once through the mouse's nose to the airways.
Two days after the pbadage of the fine dust introduced into the body, fine dust sucked into the esophagus through the mouth was evacuated to the outside of the body after 48 hours.
However, the fine dust inhaled into the airways through the nose showed the opposite result.
The rat inhaled the fine dust through the nose and the respiratory tract, and the time has pbaded, it is confirmed that there is still a lot of fine dust in the lungs.
The amount of fine dust inhaled into the nose accumulated in the lungs up to 60% even after 48 hours, and was transferred to the liver and kidneys to spread the toxin.
The fine dust ingested by the nostrils is released only after a week, but it is much more fatal for the human body than for the mouth.
