1.What are occupational pneumoconioses?
The occupational pneumoconioses are a group of interstitial lung diseases caused by the inhalation of certain workplace dusts and the lung tissue's reaction to them.
Chinese laws identify 12 kinds of pneumoconioses.

Other forms of pneumoconioses can be caused by inhaling dusts containing graphite, talc, mica, aluminum, and other substances. There are also other types of occupational pneumoconioses such as carbon black pneumoconiosis, cement pneumoconiosis, potter's pneumoconiosis, welder pneumoconiosis, and founder pneumoconiosis.
In its early stages, damage caused by pneumoconioses in patients can be compensated for by the body, generally with no or only slight symptoms. With the progression of the diseases and the emergence of complications, there can be different symptoms and signs.
The most common symptoms of occupational pneumoconioses are persistent cough, expectoration, chest pain and shortness of breath, as well as wheezing and hemoptysis. Fever, liver enlargement and edema may arise from other complications.
