摘要
为探讨儿童头发中微量元素是否有协同或拮抗作用 ,测定了 6 4 6名 1～ 3岁和 380 3名 4～ 7岁儿童头发中的Zn、Fe、Cu、Ca、Mn和Pb含量 ,并研究了各元素间的相互关系 ,结果表明 :1- 3岁幼儿头发中Zn、Fe、Cu、Ca、Mn和Pb各元素间均呈正相关。 4～ 7岁儿童的发锌含量与发铅含量呈非常显著负相关 (P值均 <0 0 0 1) ,其它各元素间均呈正相关。
the relations among 6 kinds of inorganic are positive elements(Zn,Fe,Cu,Ca,Mn and Pb)in hair of children of to 7 yeas old were studied.The results showed that(1)There relations among the content of Zn,Fe,Cu,Ca,Mn and Pb in hair of to 3 year old pupils.(2)The content of Zn in hair of 4 to 7 year old pupils there are negative relations between and Pb( P <0 001),and positive relations with other elements.
