Stone cutters exposed to high levels of silica dust. (Medical News From Around The World).

HONG KONG--One thousand fifty-six patients who received long-term exposure to silica dust took part in a recent study to describe the various characteristics of their ailments.

Diseases such as pulmonary tuberculosis were suspected to be causing the distress. Upon investigation, researchers discovered that 648 patients had silicosis, which results from exposure to silica dust. Most of the patients were involved with caisson work and stone-cutting occupations in which the dust is prevalent. The patients with the most severe cases were diagnosed with massive fibrosis. Those patients had been exposed to the dust for more than 20 years.
