"Black lungs" refer to a condition known as pneumoconiosis, which is caused by the inhalation of coal dust or other particulate matter. This condition is commonly associated with coal miners, as they are often exposed to high levels of dust over long periods. The accumulation of these particles in the lungs can lead to inflammation, scarring, and reduced lung function. The term "black lung" specifically describes the dark appearance of the lungs when viewed in medical imaging due to the buildup of coal dust. Symptoms may include coughing, shortness of breath, and chest pain. Treatment focuses on managing symptoms and preventing further exposure to harmful dust.
