• Description:
  The incidence of lung cancer among mine and pottery workers in the People's Republic of China was estimated using a quantitative retrospective exposure assessment method. Twenty mines and nine pottery factories were assessed for exposure. A job dictionary was developed and historical and current exposure data and work histories were collected beginning in 1950 using data abstraction forms. A retrospective exposure matrix was developed and exposure to silica (14808607) was estimated using information on the silica content of total dust. The average estimated total dust concentration was 9mg/m3 and ranged from 28mg/m3 in the early 1950s to 3mg/m3 at the end of the 1980s. The calculation of several exposure indices, including cumulative total dust exposure, average total dust exposure, cumulative respirable silica exposure, cumulative thoracic silica exposure, as well as 13 additional indices, was described.
