摘要
目的了解宝鸡市0～14岁儿童微量元素状况,为合理补充微量元素和预防铅中毒提供依据。方法采用电位溶出法检测宝鸡市1142例儿童末梢血Zn,Fe,Cu,Mg,Ca,Pb含量。结果儿童末梢血微量元素以Zn,Ca缺乏为主,缺乏率分别为46.58%和31.09%,铅中毒发生率为12.43%;男、女儿童血铅中毒率差异有统计学意义;不同年龄组儿童血Zn缺乏率、血铅中毒率差异均有统计学意义(P值均<0.05);缺Zn、缺Ca儿童更易铅中毒。结论培养良好的饮食习惯和卫生习惯,平衡膳食,合理营养,远离铅污染,是预防儿童微量元素缺乏和铅中毒的主要措施。
Objective To study trace element status of children aged 0 - 14 in Baoji, and to provide bases for the supplementation and thq prevention of lead poisoning. Methods Totally 1 149 children＇s peripheral blood of Zn, Fe, Cu, Mg, Ca, Pb content was detected by potentiometric stripping. Results The lack of trace elements in the peripheral blood of children was mainly Zn and Ca, and the lack rates were 46.58% and 31.09%. The incidence of lead poisoning was 12.43%. Blood lead poisoning rate of boys and girls had significant difference; the rate of zinc deft. eiency and lead poisoning also had significant difference in different age groups （ P 〈 0.05 ）. The children who lacked Ca, Zn were more likely had lead poisoning.
