中山市1387名青年学生头发微量元素检测与分析

Analysis and Determination of Hair Trace Elements of 1387 Students in Zhongshan City

为了探讨中山市青年学生头发中的微量元素含量 ,测定了该市来自三个学校的 1 3 87名青年学生头发中的锌、铁、铜、钙、锰、铅含量。结果表明 ,女生与男生的头发锌含量有显著差异(P <0 0 5) ,女生与男生的头发中钙含量有高度显著差异 (P <0 0 0 1 ) ;城区与乡镇的青年学生头发中钙、铜含量有高度显著性差异 (P <0 0 1 ) ;父母文化程度高与父母文化低的青年学生头发中钙含量有高度显著性差异 (P <0 0 1 ) ;在青年学生的年龄、性别、家庭、居住地区等不同的比较中 ,以发钙值含量差异显著性最高。提示青年学生应注意饮食营养均衡 ,补充必需的微量元素 ,加强体育锻炼 。

The content of Zn,Fe,Cu,Ca,Mn and Pb was determined. The results showed that Zn content varied distinctively between boys and girls(P<0 05);Cu amd Ca content showed great differences between boys and girls (P<0 01); Ca content also had signiicant differences between students whose parents were well-educated and students whose parents were low-educated.Some indications for improving students health were also proposed.
