孕妇和儿童通常报道地球群，但其原因和后果仍然很少了解，因此，我们感觉到地球运动物是否可以通过检查Kakamega消耗的地球元素成分来造成微量营养素和/或成为重金属的来源。 ， 肯尼亚。
通过研究枚举者收集了十个通常在怀孕期间消耗的地球样本，并使用电感耦合的等离子体原子发射光谱进行了分析。
根据估计的摄入量（40 g/天），所有样品的铅水平超过了临时最大可容忍的摄入量，一个样本超过了砷的阈值，所有样品的估计摄入量至少高8.9倍已建立的阈值也被样本收集的地点比较（市场样本）；浓度比壁样品。
卡卡梅加（Kakamega）中的地球地球可能是由于危险的铅，砷和铁的危险而有害。
Geophagy is commonly reported by pregnant women and children, yet its causes and consequences remain poorly understood. Therefore, we sought to determine if geophagy could contribute micronutrients and/or be a source of heavy metal exposure by examining the elemental composition of earths consumed in Kakamega, Kenya. Ten samples of earths commonly consumed during pregnancy were collected by study enumerators and analyzed using inductively coupled plasma-atomic emission spectroscopy. Samples were either collected at markets or from walls of participants’ homes, based on where participants reported most commonly sourcing their consumed earths. Based on estimated intakes (40 g/day), all samples had lead levels that exceeded the provisional maximum tolerable daily intake, and one sample exceeded the threshold for arsenic. Further, estimated intakes of iron for all samples were at least 8.9 times higher than the established threshold. Elemental concentrations were also compared by the site of sample collection (market vs. household wall); market samples had significantly higher iron concentrations and lower calcium concentrations than wall samples. Geophagic earths in Kakamega may be harmful because of dangerously high levels of lead, arsenic, and iron. The prevalence of geophagy among vulnerable populations underscores the importance of understanding its causes and consequences for accurate public health messaging.
