| 摘 要： | 报道了应用X射线荧光光谱技术在中国本土获得的普通人群原位人体活体骨铅数据,发表了中国大陆普通居民的胫骨和根骨活体骨铅浓度及其研究结果。采用Pb的K系谱线进行了原位活体分析人胫骨和根骨骨铅含量。普通人群样本中所测骨铅含量加权平均值在0.4～22.7μg.(g骨矿物质)-1之间,不确定度在7.0～12.5μg.(g骨矿物质)-1之间,平均最小检出限20.3μg.(g骨矿物质)-1。在污染调查区居民中发现骨铅最高可达73.9μg.(g骨矿物质)-1。

| Abstract: | The data of in vivo XRF Pb in human bone were obtained within China by using the in vivo XRF set. The K series X-ray of Pb were applied to determine the in vivo Pb concentration in tibia and calcaneus among Chinese mainland residents. For general population, the weighted average of Pb in bone was 0.4-22.7 microg x (lead g bone mineral)(-1). The uncertainty was 7.0-12.5 microg x (lead g bone mineral)(-1), and the average minimun detection limit was 20.3 microg x (lead g bone mineral)(-1). For residents from pollution area, the maximum Pb in bone reached up to 73.9 microg x (lead g bone mineral)(-1). |
