人发元素分析作为评价人体摄入环境污染物意义的研究

The significance of hair mineral analysis for assessing internal body burdens of environmental mineral pollutants

用仪器及放化中子活化分析法研究了人发微量元素与人体内脏器官的相关性。对人体生物样品中的毒性元素As、Cd、Hg及人体必需元素Se、Cu、Zn含量作了分析。从24例男性尸体的器官组织肝、肾、肺、大脑及人发研究结果表明,在发As和肾As之间,在发Se和肝、肾、肺Se水平之间存在有明显的相关性。吸烟与否与体内肾Cd和肺Cd的积累有明显的差异,但对其余元素As、Se、Cu、Zn、Hg在人发和内脏器官组织水平之间未观察到有显著的相关性。

Samples from 24 male corpses have been collected to study the correlation of minerals in hair to those in internal tissues (liver,kidney, lung and brain) by NAA. Positive correlations of As in hair to that in kidney and Se in hair to Se in liver, kidney and lung have been observed.
