摘要(中)日光燈管製程中,因汞的外洩造成作業環境中汞蒸氣濃度的增加,而加重勞工汞暴露的狀況。行政院勞委會曾分別於民國七十九年、八十四年及八十九年三度對日光燈工廠進行作業環境勞工汞暴露調查,並給於適度建議及改善措施。為進一步了解目前國內日光燈從業人員汞的暴露狀況,因此進行此研究調查。 本研究分別針對台灣地區二家日光燈工廠及一家冷陰極燈管工廠之勞工進行暴露調查,汞蒸氣吸附管用以採集作業場所汞蒸氣及勞工尿液檢體,以冷汞蒸氣原子吸收光譜儀進行分析。探討目前國內日光燈工廠勞工汞的暴露狀況,並比較歷年資料是否有下降或上升的趨勢。 研究結果顯示,日光燈工廠作業場所汞蒸氣濃度與過去檢測資料比較,有改善降低現象,且皆低於法定標準值(0.05 mg/m3);勞工尿中無機汞濃度亦低於ACGIH之BEI值(35 μg/g Crn)。但若因工作年資長而長期暴露汞蒸氣,則體內無機汞濃度會有緩慢增加之趨勢。冷陰極燈管工廠,因其密閉作業及填加汞合金之作業環境,故不論作業場所汞蒸氣濃度或勞工尿中無機汞濃度皆小於法定標準值。
摘要(英)  The transpired mercury during the manufacturing process of fluorescent lamp would increase the mercury vapor pressure in the working place and lead to accumulation of inorganic mercury inside the workers. The Council of Labor Affairs conducted several investigations of occupational exposure to mercury for this particular industry in 1990, 1995, and 2000, respectively. Accordant advices and modifications were provided. This study was conducted to evaluate the current mercury exposure of fluorescent lamp workers.   This study investigated the mercury exposure of workers in two conventional fluorescent lamp and one cold cathode fluorescent lamp manufactures in Taiwan. Mercury vapor was collected from workplaces by Hydrar sorbent tubes, while urine samples of exposed workers were also collected for biological monitoring purpose. All samples were analyzed by cold mercury vapor atomic absorption spectrometer. The results were utilized to evaluate the current mercury exposure in the fluorescent lamp industry and to compare with the historical investigation data.   The results suggested that in fluorescent lamp factories, the mercury vapor concentrations in workplaces were lower than the regulation standard (0.05 mg/m3). And the values showed a trend of decline while comparing with the historical data. As for the biological monitoring of workers’ urine samples; the majority was lower than the BEI recommended by ACGIH (35 μg/g Crn). The data suggested that accumulation of inorganic mercury correlated with prolonged exposure (working years in this industry). While in the cold cathode fluorescent lamp factory, both the vapor concentrations in workplaces and the inorganic mercury in urines of the exposed workers were lower than the regulation standard. Key words: mercury vapor, urine, speciation, cold mercury vapor atomic absorption spectrum analyzer
