在研究铅的职业接触和环境中铅的浓度关系时,血铅是必须监测的生物指标,因血铅浓度能正确反映铅的接触、吸收和排泄程度。近年来,应用原子吸收光谱法测定血中痕量元素铅的浓度已日益显示它的重要性。本文介绍了应用电热原子吸收光谱法测定全血中的铅,其优点是灵敏度高、准确、快速、简便、取血量少(20μl),对于来源困难的血液更显示其优越性。
When studying the relationship between lead exposure and the concentration of lead in the environment, blood lead is the biological indicator that must be monitored. The blood lead level correctly reflects the level of lead exposure, absorption and excretion. In recent years, the determination of lead in blood by atomic absorption spectrometry has increasingly shown its importance. This article describes the application of electrothermal atomic absorption spectrometry for the determination of lead in whole blood. The advantage of this method is its high sensitivity, accuracy, rapidity and convenience. It takes less blood (20μl) and shows its superiority to the blood with difficult source.
