Final answer:
Anthracosis, also known as black lung disease, is caused by the inhalation of coal dust and leads to respiratory symptoms.
Step-by-step explanation:
Anthracosis, also known as black lung disease, is a type of pneumoconiosis caused by the inhalation of coal dust. It occurs in coal miners and other coal workers who are exposed to coal dust over a long period of time.
Inhalation of coal dust leads to the progressive build-up of coal particles in the lungs, which causes inflammation, fibrosis, and tissue damage. This condition can result in respiratory symptoms such as coughing and shortness of breath.
