What is a common effect of excessive exposure to silica dust?

Excessive exposure to silica dust can lead to a condition known as silicosis, which is a type of pneumoconiosis resulting from inhaling crystalline silica particles. Silicosis results in the formation of scar tissue in the lungs, which can severely impair respiratory function over time. This disease is characterized by inflammation and scarring, leading to symptoms such as coughing and shortness of breath as the condition progresses.

Unlike the other options, which may be associated with different health issues, silicosis is a direct result of inhaling silica dust specifically and is well-documented as a significant risk for individuals working in environments where silica dust is prevalent, such as mining, construction, and certain manufacturing processes. Understanding silicosis is crucial for recognizing the long-term health risks associated with silica exposure and implementing appropriate safety measures to protect workers.
