What is the difference between pneumoconiosis and silicosis?

Silicosis is caused by long-term inhalation of a large amount of free silica dust. It is characterized by extensive nodular fibrosis of the lungs. Pneumoconiosis refers to a disease caused by dust accumulation in the lungs of patients during productive labor. It can be divided into organic dust and inorganic dust. The difference between the two is that the pathogenic substance of silicosis is free silica. In addition to free silica, the pathogenic substances of pneumoconiosis also include other toxic dusts and cotton. Pneumoconiosis includes silicosis, and pneumoconiosis has a wider range.
