[0002] Dust refers to solid particles suspended in the air. Dust is customarily called by many names, such as dust, dust, smoke, mine dust, sand dust, powder, etc. The International Organization for Standardization stipulates that solid suspended matter with a particle size of less than 75μm is defined as dust. The presence of dust in the atmosphere is one of the main reasons for maintaining the earth's temperature. Too much or too little dust in the atmosphere will have a catastrophic impact on the environment. However, in life and work, productive dust is the natural enemy of human health and the main cause of many diseases.
