1. The pneumoconiosis

Pneumoconiosis is to point to the disease that produces sex dust place to cause with pulmonary tissue fibrosis give priority to in producing process. As a result of the quality of inhalation of dust and the amount of the different attack is not the same degree of harm. There are many kinds of pneumoconiosis, among which 12 kinds are classified as industrial diseases. They are: silicosis, coal worker’s pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestosis, talc lung, cement lung, mica lung, potter’s pneumoconiosis, aluminum pneumoconiosis, welding mixed pneumoconiosis, cast worker’s pneumoconiosis. Cup mask manufacturers mentioned that the chemical composition of dust is one of the main factors to determine the size of the hazard to human health. To understand the hazard of dust, we should know whether the dust is rich in toxic substances, radioactive substances and free silica content. The higher the content of free silica in the dust, the more inhaled amount, the faster the development of the disease, and the more severe the degree of fibrosis. Hazards of different kinds of dust to human body:

(1) Silica dust, rich in free silica dust, such as quartz, can cause pulmonary fibrosis after inhalation.

(2) Asbestos dust can cause asbestosis and induce lung cancer and stromal tumor.

(3) Radioactive dust, such as uranium dust, can cause radiation hazards and induce lung cancer.

(4) toxic dust, such as lead dust, cadmium, manganese, chromium and other metal dust, can attack a variety of poisoning reflected.

(5) Harmful dust, such as coal dust, cement dust, can attack pulmonary fibrosis.

2. Dust calmness disease

Some metal (iron, barium, tin, etc.) dust inhalation found that some metal (iron, barium, tin, etc.) can be in the lung tissue foreign body reaction, and continue to fibrosis, but small harm to the human body, from the dust operation, the disease can gradually fade.

3. Respiratory symptoms

The partial effect of dust refers to that dust ACTS on the respiratory tract mucosa and causes its atrophy. In addition, can also constitute pharyngitis, laryngitis, tracheitis and so on; Action on the skin can constitute acne, folliculitis, pyoderma, etc.; Metal and abrasive dust can cause corneal damage, resulting in dull corneal feeling and corneal turbidity; Asphalt soot under sunlight can cause photodermatitis. Cup mask manufacturers found that the toxic effect of dust refers to the inhalation of lead, arsenic, manganese and other toxic dust caused by poisoning scene.

4. Pulmonary lesions caused by organic dust

Organic dust includes plant, animal and artificial organic dust. There are cotton, tobacco, flour, sawdust, fuzz, fur coat, fuel, plastic, asphalt and so on. Different organic dust has different biological effects, such as bronchial asthma, cotton dust disease, occupational allergic pneumonia, mixed pneumoconiosis, etc.
