利用原子吸收光谱对信阳市104例7个月—9岁儿童发锌含量进行了分析研究,结果表明,发锌含量与小儿年龄呈负相关,7个月—7岁小儿年龄与标准差呈负相关,这提示我们,年龄越小,发锌含量越高且越不稳定。
104 cases of hair zinc content of children before nine years were determined by atomic absorption spectrophotomctry in Xingyang city The results show that there is significant negative correlation between the contents and the ages and so it is with the standard differences of hair zine and the above children' s ages, i.c the gounger the children are, the higher and the less steady the hair zine contents are..
