Abstract: Longitudinal inception cohort study (1974-2004) on miners who started working underground at two coal mines in Germany between 1974 and 1979. From the continuous exposure monitoring, the numbers of the shifts exposed and the shift-average concentration are available, so that long-term average and cumulative concentration of respirable coal dust and quartz component can be derived. The effects of exposure on lung function parameters (FVC, FEV1, FEV1/FVC) were estimated with generalized estimation equation (GEE) models, after adjusting for anthropometric factors, smoking behaviour, and lung function measuring devices.
