摘　　要：为了解学前儿童头发中铅锌含量及两元素间的关系，采用火焰原子吸收分光光度法对昆明市三所幼儿园４００名学前儿童进行了发中铅锌含量测定。结果表明，发铅≥１０×１０－６者２３２人，占５８％；发锌≤１００×１０－６者２４０人，占６０％；铅锌两元素呈负相关。昆明市儿童发铅水平较高，普遍存在缺锌情况。铅锌在体内可能存在互为竞争的拮抗作用。Zn and Pb level in hair of 400 preschool children in Kunming was determined by FAAS.The results showed children's level in hair was higher,and most children had zinc deficiency.There may be an antagonistic function between lead and zinc in body.
