The lead content of hair in workers occupationally exposed was correlated with the blood lead concentration. Determinations of lead in blood and hair were performed by electrothermal atomic absorption spectrophotometry in two exposed groups and a control group. A significant correlation was observed between the blood lead and hair lead concentrations, and a regression analysis showed an exponential accumulation of the lead content in hair, simultaneously with the increase of the values in blood. The colour of the hair and the age of the subject did not influence the lead accumulation in hair in the occupationally exposed subjects. The assessment of lead in hair is considered a useful screening test in estimating occupational exposure.
职业暴露工人头发中的铅含量与血铅浓度相关。采用电热原子吸收分光光度法对两个暴露组和一个对照组进行了血铅和发铅测定。观察到血铅和发铅浓度之间存在显著相关性，回归分析表明，随着血铅值的增加，头发中的铅含量呈指数累积。头发颜色和受试者年龄对职业暴露受试者头发中的铅蓄积没有影响。头发铅含量的评估被认为是估计职业暴露的一种有用的筛查测试。
