Contrast Microscopy. Specific job matrix used to calculate job exposure. Each day in the work history was assigned an exposure level based on the job exposure matrix and cumulative exposure was defined as the sum of the assigned exposure concentrations over all days worked. Mortality analysis (observed pneumoconiosis and other respiratory diseases deaths=85, asbestosis=42) showed increasing trends in pneumoconiosis SMRs with increasing cumulative exposure were observed overall from 3-<16 (SMR 2.43; (1.33-4.08). Asbestosis mortality (observed deaths=62) showed statistically significant interaction between cumulative exposure and age category was observed (p=0.026).
