本文通过收集职业性接触汞蒸气女工和对照组在分娩时的母体血、脐带血、胎盘和乳汁生物样品,应用原子吸收光谱法测定其汞含量以及胎盘Pb、Mn、Cd、Zn、Fe、Mg、Ca和Se微量元素含量,并随访观察两组子代的生长发育情况。研究结果表明,接触组乳汁、母体血、脐带血和胎盘汞含量均显著高于对照组,表明职业性接汞可使女工体内汞
In this paper, we collected maternal blood, umbilical cord blood, placenta and milk samples from workers and controls exposed to mercury vapor and determined the contents of mercury and the contents of Pb, Mn, Cd, Zn, Fe, Mg in the placenta by atomic absorption spectrometry , Ca and Se trace elements, and follow-up observation of the growth of the two groups offspring. The results showed that milk, maternal blood, umbilical cord blood and placental mercury levels in the exposed group were significantly higher than those in the control group, indicating that occupational mercury exposure could lead the female workers’ mercury
