Silica exposure and silicosis among Ontario hardrock miners: III. Analysis and risk estimates

Am J Ind Med. 1989;16(1):29-43. doi: 10.1002/ajim.4700160105.


An epidemiological investigation was undertaken to determine the relationship between silicosis in hardrock miners in Ontario and cumulative exposure to silica (free crystalline silica--alpha quartz) dust. This report describes the analytic method and presents the risk estimates.
