Abstract

From literature data, a negative correlation was derived between the normal average hair zinc levels of 5-yr-old children and the calcium levels in their drinking water (hair zinc level in mg/kg=-(0.158±0.003) calcium level in mg/L+134;r=0.993,n=6,p=0.0006). Exposure of hair samples of a 5-yr-old child to water with different levels of calcium and zinc did not provide evidence for an exogenous effect of calcium in drinking water on hair zinc levels. Thus, these results support Gibson's hypothesis that calcium in hard drinking water interferes with Zn absorption.

摘要

从文献资料中得出，5 岁儿童正常平均头发锌水平与饮用水中钙水平呈负相关（头发锌水平（mg/kg）=-(0.158±0.003) 钙水平（mg/L）+134；r=0.993，n=6，p=0.0006）。将 5 岁儿童的头发样本暴露于不同钙和锌水平的水中，并未提供饮用水中钙对外源性影响头发锌水平的证据。因此，这些结果支持 Gibson 的假设，即硬水中的钙会干扰锌的吸收。
