Where do people working get black lung disease?

People working in (d) Coal mines are at risk of developing black lung disease, also known as coal workers’ pneumoconiosis (CWP). This condition occurs due to prolonged exposure to coal dust, which is inhaled and deposited in the lungs. Over time, the accumulated coal dust causes inflammation, scarring, and fibrosis in the lung tissue, leading to respiratory symptoms such as coughing, shortness of breath, and chest tightness. Unlike the electroplating (a), organic solvent (b), and paint manufacturing (c) industries, where workers may face different occupational hazards, black lung disease specifically affects those working in coal mining environments.
