A heterogeneous group of asymptomatic industrial workers potentially exposed to various toxic metals was screened for trace metal exposure. Each was examined and then completed an occupational health history questionnaire and had hair and blood samples analyzed for 10 metals via the inductively coupled plasma-atomic emission spectroscopy technique. No industrial hygiene survey was performed. The concentrations of trace elements found in our cohort were comparable to previously published levels for nonoccupationally exposed groups. This finding is not unexpected in light of the nature of the population studied and the screening technique. The levels in blood and hair were not well correlated, and subsets of the population with high metal burdens could not be identified on the basis of self-reported occupational exposure histories.
对一组可能接触各种有毒金属的无症状产业工人进行了筛查，以检测其微量金属暴露情况。对每个人进行了检查，然后他们填写了职业健康史问卷，并通过电感耦合等离子体原子发射光谱技术对头发和血液样本中的10种金属进行了分析。未进行工业卫生调查。我们队列中发现的微量元素浓度与先前公布的非职业暴露组水平相当。鉴于所研究人群的性质和筛查技术，这一发现并不意外。血液和头发中的水平相关性不佳，无法根据自我报告的职业暴露史确定金属负荷高的人群亚组。
