Which lung disease is associated with the inhalation of coal dust?

The disease associated with the inhalation of coal dust is anthracosis. This condition is a type of pneumoconiosis, which specifically results from the accumulation of carbon particles in the lungs due to prolonged exposure to coal dust. The inhaled particulate matter can lead to inflammation and fibrosis of lung tissue, thereby impairing lung function over time. Anthracosis is often seen in coal miners or those living in areas with high coal dust exposure.

In contrast, aphonia refers to a complete loss of voice, which does not relate to coal dust inhalation. Anosmia is the loss of the sense of smell, and dysphonia involves difficulty in speaking due to voice disorders, neither of which are linked to coal dust exposure or lung diseases. These distinctions help clarify why anthracosis is the correct answer in the context of lung diseases associated with coal dust inhalation.
