Abstract

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.

人胎盘、脐带、脐带血和羊水中汞浓度及其与新生儿身体参数的关系

研究的样本来自波兰的产妇(n = 40)，代表三个年龄组:19-25岁、26-30岁和31-38岁。采用流式原子吸收光谱法测定胎盘、脐带、脐带血和羊水中的汞浓度。胎盘重量未超过750 g，重量大于310 g。血、胎盘、脐带中汞浓度平均值相近，均为9 μg/g。脐带血汞含量高，在所有观察中有75%超过了美国环境保护局规定的安全剂量(5.8 μg/L)(最高达17 μg/L)。各年龄组妇女组织中汞含量差异无统计学意义。胎盘、脐带及脐带血汞浓度与妊娠指标呈正相关，与妊娠指标呈负相关。

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
