目的韩国幼儿园部分儿童膳食中锡的摄入量可能增加。本研究的目的是探讨这种可能性，并澄清程度的elevation.Methods24小时的食物重复和现场尿样收集在2003-2004年从108 4-6岁的儿童（男孩和女孩合并）在4所幼儿园（1在首尔和3在济州岛），在以前的出版物中报道。这些样品用于本分析，以检查饮食（包括饮料）中的锡水平（Sn-D）。将一部分样品湿灰化，并通过ICP-MS方法分析液体样品中的Sn。结果108例患者的Sn-D呈极偏倚分布，可分为两组，第一组与第二组，第三组与第四组，差异有显著性（P <0.05）。Sn <10 μg/d者占90%，>10 μg/d者占10%。前一组的Sn-D呈准正态分布，AM（中位数）为2.9（2.5）μg/天。后一组的最大值为3012 μg/天。尿锡与尿锡之间无相关性。将研究结果与已发表的文章进行比较，强烈表明高Sn-D是由于食用了保存在镀锡罐中的食物（包括饮料）。没有积极的确认，但可能由于信息不足的食物records.ConclusionsAbout 10%的儿童调查有升高的锡-D（高达3毫克/天）。高锡-D很可能与锡罐头食品的摄入有关。
ObjectivesDietary intake of tin (Sn) may be increased in some children in kindergartens in Korea. The present study was intended to examine this possibility and clarify the extent of the elevation.Methods24-hour food duplicate and spot urine samples were collected in 2003–2004 from 108 4–6-year-old children (boys and girls combined) in 4 kindergartens (1 in Seoul and 3 in Jeju Island), as reported in a previous publication. These samples were employed in the present analyses to examine tin levels in the diet (including beverages) (Sn-D). A portion of the samples were wet-ashed, and the liquid samples were analyzed for Sn by the ICP-MS method. For statistical evaluation, χ2 method and Smirnov’s test for extreme value were used.ResultsSn-D in the 108 cases distributed as extremely biased, and could be divided into two groups, i.e., those with <10 μg Sn/day (accounting for 90 % of the cases), and those with >10 μg/day (for 10 %). Sn-D in the former group was distributed quasi-normally with an AM (median) of 2.9 (2.5) μg/day. The maximum in the latter group was 3012 μg/day. No correlation was detected between Sn-D and Sn in urine (Sn-U). Comparison of the findings with published articles strongly suggested that the high Sn-D was due to consumption of foods (including beverages) preserved in tin-plated cans. No positive confirmation was however possible due to insufficient information on food records.ConclusionsAbout 10 % of children surveyed had elevated Sn-D (up to 3 mg/day). It was quite possible that high Sn-D was associated with tin-canned food intake.
