The polishing and dust removal company learned that after the dust enters the alveoli, the macrophages in the alveoli treat the dust as foreign bodies and swallow it, leading to a series of complex body reactions, promoting fibrosis of the lung tissue, and gradually losing the ventilation function of the affected alveoli. "Death", when a large number of alveoli lose ventilation function, eventually lead to pneumoconiosis, and the patient feels chest tightness and difficulty breathing. Long-term development can produce many complications such as emphysema, infection, tuberculosis, etc. The patient eventually dyspnea combined with complications and died.
Occupational respiratory diseases have the following four manifestations:
Pneumoconiosis refers to diseases that are mainly caused by fibrosis of lung tissue caused by inhalation of productive dust during the production process. There are different degrees of harm due to the quality and quantity of inhaled dust. There are many types of pneumoconiosis, of which 12 are classified as occupational diseases. They are: silicosis, coal worker pneumoconiosis, graphite pneumoconiosis, carbon ink pneumoconiosis, asbestos lung, talc lung, cement lung, mica lung, potter's pneumoconiosis, aluminum pneumoconiosis, welding pneumoconiosis, and caster pneumoconiosis.
Some metals (iron, barium, tin, etc.) after inhaling the dust can react with foreign bodies in the lung tissue and continue to be slightly fibrotic, but it is less harmful to the human body. After the dust is removed, the lesions can gradually disappear.
3.Lung lesions caused by organic dust
The polishing and dust removal company has different biological effects for different organic dusts, such as causing bronchial asthma, cotton dust disease, occupational allergic pneumonia, and mixed pneumoconiosis.
4. Respiratory system tumors
The local effect of dust refers to the atrophic lesions caused by the dust on the mucous membranes of the respiratory tract; in addition, it can also form smoke, laryngitis, bronchitis, etc .; it can form acne, folliculitis, pus skin disease, etc. on the skin; metal and abrasive dust Can cause corneal damage, resulting in dull corneal sensation and corneal turbidity; asphalt soot can cause photosensitivity dermatitis under sunlight. The poisoning effect of dust refers to the poisoning phenomenon caused by inhalation of toxic dust such as lead, arsenic and manganese.
