||Beryllium particulate exposure and disease relations in a beryllium machining plant

||The relationship between exposure to beryllium and beryllium sensitization (BeS) and chronic beryllium disease (CBD) was examined in workers in a beryllium machining plant. 20 workers with BeS or CBD (cases) were compared with 206 worker-controls. Cases were more likely to have worked as machinists (odds ratio=4.4) than controls. The median cumulative exposure was 2.9µg/m3-years in the cases versus 1.2µg/m3-years in controls for total exposure, and 1.7µg/m3-years in the cases versus 0.5µg/m3-years in the controls for exposure to particles <6µm in diameter. Odds ratios were 2.4 for the intermediate exposure group and 1.2 for the high-exposure group compared with the low-exposure group. The median lifetime-weighted (LTW) exposure was 0.25µg/m3 in both groups. The median LTW exposure to particles <6µm was 0.20µg/m3 for cases and 0.14µg/m3 for controls. None of the 22 workers with LTW exposure <0.02µg/m3 had BeS or CBD. Twelve workers in the case group had LTW exposures >0.20.
