Abstract

Lead content in head hair of 53 gas station workers together with an equal number of normal controls was determined. Samples of hair were washed with ethanol and water and microwave-aided wet digested prior to the determination of lead by flow injection/atomic absorption spectrometry. The lead content in hair of the gas station workers (48.7 +/- 17.5 micrograms/g) was significantly higher than that of the normal controls (17.2 +/- 8.1 micrograms/g). The effects of washing and sample digestion procedures, head sampling site, hair color, age, smoking habits and duration of exposure to the metal are discussed.

摘要

测定了53名加油站工作人员以及同等数量正常对照者头发中的铅含量。头发样本先用乙醇和水清洗，然后进行微波辅助湿法消解，再通过流动注射/原子吸收光谱法测定铅含量。加油站工作人员头发中的铅含量（48.7±17.5微克/克）显著高于正常对照者（17.2±8.1微克/克）。文中讨论了清洗和样品消解程序、头部采样部位、头发颜色、年龄、吸烟习惯以及金属暴露时长的影响。
