摘要

針對兩個高鉛暴露工廠，因年假停工，藉此瞭解短時間停止作業，對員工血鉛的影響。我們利用農曆年前及年假結束後，分別抽取35名鉛作業員工前、後兩次血液檢體，以原子吸收光譜儀分析血鉛濃度。結果顯示：35名受測員工，前、後測血鉛濃度平均差達統計上顯著差異，表示整體來看停工後員工血鉛濃度有下降的現象。若分別針對個別工廠員工前、後測比較，亦有相同發現，即是血鉛濃度前、後測平均差均達統計顯著差異，表示前測血鉛濃度高於後測。此研究報告說明暫離鉛暴露源對血鉛含量下降是有幫助的，縱使只是短時間的停止暴露。

At two high lead-exposure factories, the Chinese New Year break provided a chance to investigate the effect of such short breaks on the workers' blood lead levels. Thirty-five lead operators were selected and their blood was drawn twice, before and after the Chinese New Year break, and measured for lead concentration using an atomic absorption spectrometer. The results showed that there was a significant difference in blood lead levels: overall the workers' blood lead levels decreased over the holiday. Looking at the factories individually, the result was the same: there was a statistically significant drop. This research shows that even temporary removal from lead exposure is beneficial for lowering the concentration of lead.
