Which health effect is commonly associated with asbestos exposure in Libby, Montana?

• A. Kidney failure
• B. Hearing loss
• C. Respiratory problems
• D. Skin rashes

Answer: (C)

Exposure to asbestos primarily affects the lungs and breathing. In Libby, Montana, contamination from the vermiculite mine released asbestos fibers into the air people breathed for years, leading to lung and pleural diseases. When inhaled, these fibers irritate and scar lung tissue, causing conditions like asbestosis and pleural disease, and they raise the risk of lung cancer and mesothelioma. The most common health effects are chronic respiratory problems—persistent coughing, shortness of breath, chest tightness, and wheezing. Kidney failure, hearing loss, or skin rashes are not typical outcomes of asbestos exposure, though skin irritation can occur with direct contact. Thus, respiratory problems are the health effect most commonly associated with this exposure.
