Pneumoconiosis

Pneumoconiosis is an occupational lung disease caused by the inhalation of dust. Depending on the type of dust, variants of the disease are considered.

Types include:

• Coalworker's pneumoconiosis (also known as "black lung") - coal dust
• Asbestosis - asbestos dust
• Silicosis (also known as "grinder's disease") - silica dust
• Bauxite fibrosis - bauxite dust
• Berylliosis - beryllium dust
• Siderosis - iron dust
• Byssinosis - cotton dust
• Labrador Lung (found in miners in Labrador, Canada) - mixed dust, including iron, silica and anthophyllite, a type of asbestos

Pneumoconiosis in combination with multiple pulmonary rheumatoid nodules in rheumatoid arthritis patients is known as Caplan's syndrome.^[1]

Alec: “Oh yes, the inhalation of coal dust…That’s one specific form of the disease. It’s called anthracosis.”

Laura [Tenderly]: “What are the others?”

Alec: “Chalicosis. That comes from metal dust. Steel works, you know…”

Laura [Breathlessly]: “Yes, of course… Steel works…”

Alec: “And silicosis… That’s stone dust… Gold mines…”

Laura [Almost swooning]: “I see…”
