Mercury exists worldwide in food, water and air throwing its health hazards on all body systems.
To show the influence of the presence of mercury in pregnant mothers' blood on its level in the umbilical cord blood; and to display the relationship between the different foodstuff on the mercury levels in pregnant mothers' and umbilical cord blood.
This cross-sectional study was conducted on randomly chosen 113 pregnant mothers at the time of labour and on their newborns. Full history, sociodemographic data and food frequency questionnaire for dietary assessment were recorded. The Maternal and neonatal anthropometric measurements together with the Apgar scoring were also measured. Serum mercury levels in both mothers' and umbilical cord blood were measured using the Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
A high percentage of mothers (82.3%) were exposed to passive smoking. There was a statistically significant positive correlation between the maternal and fetal umbilical cord blood mercury levels (p = 0.002). There was an insignificant negative correlation between the maternal blood and fetal umbilical cord blood mercury levels on one side and each of the different foodstuff on the other side (fish, vegetables, fruits and proteins, for example, meat and legumes). An insignificant positive correlation was found between dairy products and of the maternal blood and umbilical cord blood mercury levels.
The fetal umbilical cord blood mercury levels correlate positively with the maternal blood mercury. The different foodstuff can influence the maternal and umbilical cord blood mercury levels whether by increase or decrease. Strict measures should be taken to decrease environmental mercury contamination with attention to pregnant mothers.
汞在全球范围内存在于食物、水和空气中，对人体所有系统都有健康危害。
研究孕妇血液中汞的存在对脐带血汞水平的影响；并展示不同食物与孕妇和脐带血中汞水平之间的关系。
本横断面研究在随机选取的113名分娩时的孕妇及其新生儿中进行。记录了完整病史、社会人口学数据以及用于饮食评估的食物频率问卷。还测量了母婴人体测量指标以及阿氏评分。使用电感耦合等离子体质谱法（ICP-MS）测量母亲和脐带血中的血清汞水平。
高比例的母亲（82.3%）暴露于被动吸烟环境。母亲和胎儿脐带血汞水平之间存在统计学显著的正相关（p = 0.002）。母亲血液和胎儿脐带血汞水平与各类不同食物（如鱼类、蔬菜、水果和蛋白质类食物，如肉类和豆类）之间存在不显著的负相关。乳制品与母亲血液和脐带血汞水平之间存在不显著的正相关。
胎儿脐带血汞水平与母亲血液汞水平呈正相关。不同食物可通过增加或降低汞水平来影响母亲和脐带血汞水平。应采取严格措施减少环境汞污染，尤其要关注孕妇。
