Abstract |
The prevalence of beryllium sensitization in relation to work process and beryllium exposure measurements was examined in a beryllia ceramics plant that had operated since 1980. 97.8% of the workforce was interviewed, beryllium sensitization was ascertained with the beryllium lymphocyte proliferation blood test and historical industrial hygiene measurements were reviewed. Of eight beryllium-sensitized employees, six had granulomatous disease on transbronchial lung biopsy. Machinists had a sensitization rate of 14.3% compared to a rate of 1.2% among other employees. Daily weighted average (DWA) estimates of exposure for machining processes also exceeded estimates for other work processes in that time period, with a median DWA of 0.9µg/m3. Machining process DWAs accounted for the majority of DWAs exceeding the 2.0µg/m3 OSHA standard, with 8.1% of machining DWAs above the standard. It is concluded that lowering machining process-related exposures may be important in the lowering of risk of developing beryllium disease. |
