Are silica dust , diesel exhaust , and painting work the significant occupational risk factors for lung cancer in nonsmoking Chinese men?
This study found an increased risk of lung cancer among nonsmoking Chinese men occupationally exposed to silica dust, diesel exhaust, and painting work.
Using questionnaires in this study produced data on a greater number of patients compared with examination of hospital records. However, the two data sources did differ in the quantity of physiotherapy used and this should be taken into account in any analysis.
