Pneumoconiosis is primarily caused by what?

• A. Genetic factors
• B. Exposure to organic pollutants
• C. Inhalation of inorganic hazards
• D. Viral infections

Answer: (C)

Pneumoconiosis is primarily caused by the inhalation of inorganic dusts and particles, making the option regarding inhalation of inorganic hazards the correct choice. This condition arises when individuals, especially in specific occupational settings, are exposed to harmful substances such as asbestos, silica, or coal dust over long periods.

The inhaled particulate matter causes chronic inflammation and fibrosis within the lungs, leading to impaired lung function and potentially serious respiratory issues. Unlike other causes of lung disease, pneumoconiosis is specifically linked to the nature of the particles inhaled and not influenced significantly by genetic predispositions, organic pollutants, or viral infections. Therefore, understanding that pneumoconiosis is fundamentally an occupational lung disease resulting from inorganic dust exposure is crucial in identifying its causes and preventing its occurrence.
