• Description:
  An investigation was conducted to gain insight into the extent of free silica (7631869) variation in respirable mine dust samples collected from a sample of United States coal and noncoal mines. A second goal was to determine the factors associated with this variation. A total of 374 personal and area samples were collected in the participating mines during 55 sampling days. Occupation and mine, sampler position, laboratory analysis and repeated sampling time contributions to sample variance were estimated based on the paired sample results and published values for variance associated with laboratory analysis and air sampling techniques. The largest contributions to variance arose from sampling across mines and occupations, which accounted for 46% of the variability associated with respirable mine dust samples. The second important contributor to variance was the temporal variability of dust levels in mines, accounting for approximately 33% of total variability. The authors conclude that the largest contribution to variability results from sampling across mines.
