Abstract |
Historical data on the dust exposures of Chinese workers in mining and pottery industries are being used in an ongoing epidemiological study to investigate the exposure-response relationship for silicosis, lung cancer and other diseases. Total particle concentrations were determined by a Chinese method, which does not provide data on particle size distribution. Therefore, in order to assess these exposures in light of American respirable dust exposure standards, conversion factors are needed to convert total dust concentrations to respirable dust concentrations. In order to estimate these factors, more than 100 airborne dust samples were collected in 20 mines and nine pottery factories in China during 1988 and 1989. Based on multivariate statistical analysis, a mean conversion factor of 0.25±0.04, was derived for all the job titles and industries, enabling respirable dust levels to be estimated from the historical total dust concentrations collected between 1952 and 1992. |
