摘要
测定了 5 2 0例幼儿头发中锌 (Zn)和铅 (Pb)含量 ,分别为 ( 97 5 4± 2 8 1 9)× 1 0 - 6、( 1 5 2 2± 5 0 2 )× 1 0 - 6。相关分析表明 ,男女幼儿头发中Zn与Pb含量均存在着非常显著的负相关关系 ,P <0 0 0 1。这两种元素含量在男女幼儿之间没有显著差异。
The relations between Zn and Pb in hair of children were studied.The results showed that (1)The relations between the content of Zn and Pb in hair were negative(P<0.001).(2)The content of Zn and Pb in hair was(97.54±28.19)×10 -6 and(15.22±5.02)×10 -6 .There was no difference between boys and girls in Zn and Pb in hair.
