近年来缺锌缺铁的报告屡有发表,微营养缺乏的问题已经引起广泛的关注。调查发现徐州市少年儿童血清锌水平较低,血清铜含量较高;徐州市居民从饮水中获取的锌、铁、铜等微量元素极少。又鉴于徐州地区为铁锌性土壤,我们于1986年对徐州地区常用主要食物中锌、铜、铁的含量进行了测定和研究。 In recent years, reports of zinc deficiency and iron deficiency have been published frequently, and the problem of micro-nutrition deficiency has drawn wide attention. The survey found that children in Xuzhou City, serum zinc levels are lower, higher serum copper content; Xuzhou residents from drinking water access to zinc, iron, copper and other trace elements rarely. In view of the iron-zinc soil in Xuzhou area, we measured and studied the contents of zinc, copper and iron in Xuzhou area in 1986.
