Studies were conducted on samples taken from giving birth women (n = 40) living in Poland, representing three age groups: 19-25, 26-30 and 31-38 years old. Mercury concentrations were measured with CV-AAS in placenta, umbilical cord, cord blood and amniotic fluid. The placentas weight did not exceed the 750 g value and was heavier than 310 g. Mean values of Hg concentrations in blood, placenta and umbilical cord were similar (c.a. 9 μg/g). High levels of mercury were noted in cord blood which in 75% of all observations exceeded (up to 17 μg/L) the safe dose set by US EPA (5.8 μg/L). No statistically significant differences in medium level of Hg in all the studied tissues among age groups of women were observed. Positive correlations between Hg concentrations in placenta and umbilical cord and cord blood were revealed as well as some negative ones between mercury concentrations and pregnancy parameters.
本研究对来自波兰的 40 名分娩妇女的样本进行了研究，这些妇女代表了三个年龄组：19-25 岁、26-30 岁和 31-38 岁。采用 CV-AAS 法测量胎盘、脐带、脐血和羊水的汞浓度。胎盘重量未超过 750 克，重量超过 310 克。血液、胎盘和脐带中汞浓度的平均值相似（约 9μg/g）。在脐带血中发现了高浓度的汞，在所有观察到的样本中，有 75%的样本超过了美国环境保护署（EPA）设定的安全剂量（5.8μg/L）。在所研究的所有年龄段妇女的组织中，汞的中等水平没有统计学意义上的差异。研究还揭示了胎盘和脐带与脐血中的汞浓度之间存在正相关关系，以及汞浓度与妊娠参数之间的一些负相关关系。
