In this study, essential (Ca, Cr, Cu, Fe, K, Mg, Na, P, Zn), and non-essential (Al, Ni, Pb) element contents of the drinking and baby water samples which are sold in the local market and tap water samples in Istanbul were examined. It was determined that elements of Cr, Cu, Fe, P, Zn, Al, and Ni were below detection limits in all water samples. Among the non-essential elements analyzed in water samples, Pb was the only detected element. At the same time, the percentages that meet the daily element requirements of infants were also calculated. As a result of the evaluations made, there is no significant difference in infant nutrition between baby waters and other drinking waters in terms of the element content.

婴儿营养饮用水和婴儿水必需和非必需元素含量的测定

在本研究中，销售的饮用水和婴儿水样的必需元素（Ca、Cr、Cu、Fe、K、Mg、Na、P、Zn）和非必需元素（Al、Ni、Pb）的含量检查了伊斯坦布尔的当地市场和自来水样本。经测定，所有水样中的 Cr、Cu、Fe、P、Zn、Al 和 Ni 元素均低于检测限。在水样中分析的非必需元素中，Pb 是唯一检测到的元素。同时，还计算了满足婴儿每日元素需求的百分比。评估结果表明，婴儿水和其他饮用水的元素含量在婴儿营养方面没有显着差异。
