摘　　要：报道了1994～1995年在内蒙古呼和浩特市土默特左旗慢性砷中毒病区采集的少年头发样品中砷等十多种微量元素含量的仪器中子活化分析结果，并与北京地区同年龄段少年发样中测得的值进行了比较。发现前者除发砷含量明显高于后者外，两者在其他许多微量元素含量上也存在显著性差异，特别是慢性砷中毒地区少年头发中稀土元素（如La；Sm）和重金属元素Fe、Co、Cr等的含量均明显高于对照区。所得结果为研究呼和浩特市慢性砷中毒地区人群头发中微量元素的含量与该地区环境状况的关系，从而深入探讨这一地方病在该地区高发的原因提供了有意义的信息。The determination of contents of more than 10 trace elements in scalp hair collected from the juveniles living in the endemic arsenism area of Huhhot, Inner Mongolia (disease area group) ih 1994-1995 by means of instrumental neutron activation analysis (INAA) has been reported. A compariaon of the data from the disease area group with those from the control group, i.e. the juveniles living in Beijing area, has also been made. It ia found that besides the significantly higher hair arsenic content for the disease group than that for the conttol, there are significant differences in contents of some other elements, especially iron and the rare-earth elements such as La ahd Sm. The diffetence in hair elemental eontents between the two groups reflects the difference in environmental and nutritional status of the two areas.
