Abstract

Instrumental neutron activation analysis was performed to assess the exposure degree of a worker group from a copper smelter. The results were compared with data of inhabitants of Kinshasa and Bandaka in Zaire. Excessive concentrations of Mg, Ca, V, Co, Cu, As, and Cd were observed in the investigated group. The distribution patterns of trace elements are shown. The plots of Cu concentration relations to selected elements, i.e., As, Co, and Zn, showed a plateau at about 300 ppm of Cu.

摘要

采用仪器中子活化分析法评估了一个铜冶炼厂工人组的暴露程度。将结果与扎伊尔金沙萨和班达卡居民的数据进行了比较。在所调查的组中观察到镁、钙、钒、钴、铜、砷和镉的浓度过高。展示了微量元素的分布模式。铜与选定元素（即砷、钴和锌）浓度关系的图表显示，在铜含量约为300 ppm时出现一个平稳阶段。
