What is pneumoconiosis?

Answer 1

A disease of the lungs, such as asbestosis or silicosis, caused by long-continued inhalation of especially mineral or metallic dust.

Answer 2

What Is Pneumoconiosis

Answer 3

The pneumoconioses are diseases caused by the inhalation of inorganic dusts and represent a subset of occupational lung disease, which also includes disorders caused by the inhalation of gases, vapors, and organic material.
The many forms of pneumoconiosis have specific names, depending on the substance inhaled (Eg. silicosis, asbestosis, talcosis).
Pneumoconiosis may be classified as either fibrotic or nonfibrotic, according to the presence or absence of fibrosis.
Silicosis, coal worker pneumoconiosis, asbestosis, berylliosis, and talcosis are examples of fibrotic pneumoconiosis.
Siderosis, stannosis, and baritosis are nonfibrotic forms of pneumoconiosis that result from inhalation of iron oxide, tin oxide, and barium sulfate particles, respectively.
Two major issues complicate the etiology of pneumoconioses:
1) First is the variety of dusts to which the sufferer may have been exposed. Often workers exposed to inorganic dusts work in several occupations. It is not unusual for a gold miner, for example, to become a coal miner. In addition, mining of a particular material may generate other dusts. The best single example of this is gold mining, where miners’ lesions are due to inhalation not of gold but of quartz (silica) from the rock in which the gold is embedded.
2) Second is the difficulty in judging the relative contributions of smoking and occupational dusts to respiratory impairment, since many workers smoke cigarettes.
