Silica exposure and silicosis among Ontario hardrock miners: I. Methodology

Am J Ind Med. 1989;16(1):5-11. doi: 10.1002/ajim.4700160103.


An epidemiological investigation was undertaken to determine the relationship between silicosis in hardrock miners in Ontario and cumulative exposure to silica (crystalline silica--alpha quartz) dust. This first report describes the cohort, the method of classifying the radiographs, and the identification of a case of silicosis.
