Dust is harmful to the human body in many ways. The nasal cavity is a good dust filter for humans. Generally, dust particles larger than 10 microns are trapped in the mucus layer of the nasal cavity and upper respiratory tract under the action of gravity and inertial collision, and can be discharged with the sputum. However, excessive concentration of coarse dust in the respiratory mucosa will cause coughing, damage to the mucous membranes of the nasal cavity and upper respiratory tract, and cause bacteria to take advantage of it to cause rhinitis and pharyngitis. Dust particles less than 10 microns can enter the trachea, bronchus and filthy cavity of the human body. The dust containing free silica can cause silicosis, leading to decreased respiratory function, symptoms such as cough, shortness of breath, chest pain, fatigue, etc. death.
