Studies investigating the correlation between metal content in water and metal levels in children are scarce worldwide, but especially in developing nations. Therefore, this study investigates the correlation between arsenic, chromium, and mercury concentrations in drinking and cooking water and in blood and urine samples collected from healthy and supposedly non-exposed children from a rural area in Yucatan, Mexico. Mercury in water shows concentrations above the recommended World Health Organization (WHO) value for drinking and cooking water. Also, 25% of the children show mercury in urine above the WHO recommended value. Multivariate analyses show a significant role for drinking and cooking water as a vector of exposure in children. Also, the factor analysis shows chronic exposure in the case of arsenic, as well as an ongoing detoxification process through urine in the case of mercury. Further studies should be done in order to determine other potential metal exposure pathways among children.
全球范围内，研究水的金属含量与儿童体内金属水平之间相关性的研究很少，在发展中国家尤为如此。因此，本研究调查了墨西哥尤卡坦州农村地区健康且假定未接触过有害物质的儿童所采集的饮用水、烹饪用水以及血液和尿液样本中的砷、铬和汞浓度之间的相关性。水中汞的浓度高于世界卫生组织（WHO）推荐的饮用水和烹饪用水值。此外，25%的儿童尿液中的汞含量高于WHO推荐值。多变量分析表明，饮用水和烹饪用水作为儿童接触有害物质的载体具有重要作用。此外，因子分析表明，砷存在慢性接触情况，而汞则存在通过尿液进行持续排毒的过程。应进一步开展研究，以确定儿童中其他潜在的金属接触途径。
