用原子吸收分光光度法测定了0～7岁健康学龄前儿童4343人的头发锌含量,测出该年龄范围的发锌值下限,0～,1～,2～,3～,4～,5～,6～,7～年龄组朝鲜族男和女儿童下限值分别为38,46,53,60,77,74,82,93和41,41,59,64,73,84,93,100μg/g,发现,发锌值随年龄的增长而增加,男女间和朝汉族间发锌无明显差异,发锌值与生长发育水平之间无明显关联。
The zinc content in hair of 4343 healthy preschool children aged 0-7 years was measured by atomic absorption spectrophotometry. The lower limit of hair zinc value, 0 ~, 1 ~, 2 ~, 3 ~, 4 ~ 5 The lower limit of the Korean male and female children in ~, 6 ~, 7 ~ age groups were 38,46,53,60,77,74,82,93 and 41,41,59,64,73,84,93,100μg / g, found that hair zinc value increases with age, hair between men and women and the Han did not have significant differences between hair zinc value and the growth and development level was not significantly correlated.
