本文对长沙市19～31岁正常顺产产妇的母血、脐血和羊水样品用冷消化F-732测汞仪进行总汞含量测定。结果表明,总汞含量顺序为脐血>母血>羊水,三者之间均有显著性差异,与国内外报导的结果接近。其中脐血汞含量超过母血的46％,说明胎盘未呈现屏障作用,脐血汞含量高是否与本地区汞的存在形式有关,尚待进一步研究。
In this paper, the samples of maternal blood, umbilical blood and amniotic fluid of normal pregnant women in 19 ~ 31 years of age in Changsha City were measured with total mercury content by cold digestion F-732 mercury analyzer. The results showed that the order of total mercury was cord blood> maternal blood> amniotic fluid, with significant differences among them, which was close to the results reported at home and abroad. The mercury content of umbilical cord blood exceeded 46% of maternal blood, indicating that the placenta did not show a barrier function. Whether the mercury content in umbilical cord blood is related to the existing form of mercury in the area remains to be further studied.
