Título Prevalence of beryllium sensitization among aluminium smelter workers
Información bibliográfica Oct. 2010, Vol.60, No.7, p.569-571. 9 ref.
Resumen Beryllium exposure occurs in aluminium smelters from natural contamination of bauxite, the principal source of aluminium. The objective of this study was to characterize beryllium exposure in aluminium smelters and determine the prevalence rate of beryllium sensitization (BeS) among aluminium smelter workers. A population of 3185 workers from nine aluminium smelters owned by four different aluminium-producing companies in Italy, Norway, United States and Canada were determined to have significant beryllium exposure. Of these, 1932 workers participated in medical surveillance programmes that included the serum beryllium lymphocyte proliferation test (BeLPT), confirmation of sensitization by at least two abnormal BeLPT test results and further evaluation for chronic beryllium disease in workers with BeS. Personal beryllium samples obtained from the nine aluminium smelters showed a range of <0.01-13.00 μg/m3 time-weighted average with an arithmetic mean of 0.25 μg/m3 and geometric mean of 0.06 μg/m3. Nine workers were diagnosed with BeS. Implications of these findings are discussed.
