Pneumoconiosis
Pneumoconiosis is a lung condition caused by the inhalation of dust, characterized by formation of nodular fibrotic changes in lungs.Many substances can cause pneumoconiosis including asbestos, silica, talc and metals.
Depening on the type of dust, variants of the disease are considered. For example, silicosis, also known as grinders' disease and pneumosilicosis, is due to the inhalation of the dust of stone, sand, or flint containing silica. Since many common minerals contain silica, there are different types of silicosis.
The term Pneumonoultramicroscopicsilicovolcanoconiosis and some variants thereof turned out to be a hoax.
