【摘要】 研究了南海市西樵区 3 4 0名幼儿头发中元素含量。结果表明 ,Zn、Fe、Cu、Ca、Mn和Pb的含量 (× 1 0 - 6 )分别为 91 3 7± 2 3 2 5、 3 1 94± 4 1 6、 1 1 4 1± 3 1 3、 63 8 69± 1 2 5 4 0、 4 1 8±2 3 7和 1 3 3 7± 4 0 9。男女幼儿头发中各元素的含量没有显著性差异。该市幼儿体内有低锌高铅现象。男性幼儿头发中Zn含量与Fe含量呈正相关 (相关系数为 0 2 4 9,P =0 0 0 1 ) ,与Mn呈负相关 (相关系数为 -0 1 55,P <0 0 5)。女性幼儿头发中Fe含量与Mn含量呈显著的负相关 (相关系数为 -0 1 65,P <0 0 5)。Cu与Mn呈显著的正相关 (相关系数为 0 1 81 ,P <0 0 5)。更多还原

【Abstract】 The content of Zn,Fe,Cu,Ca,Mn and Pb in hair of 340 infants from Nanhai city was determined.The results showed that the content of Zn,Fe,Cu,Ca,Mn and Pb is(91 37±23 25)×10 -6 ,(31 94±4 16)×10 -6 ,(11 41±3 13)×10 -6 ,(638 69±125 40)×10 -6 ,(4 18±2 37)×10 -6 and (13 37±4 09)×10 -6 respectively.There is no difference between boys and girls in the levels of these elements.Zn is low and Pb is high in hair of children in Nanhai city.There is positive relation between Zn and Fe(relative coefficient is 0 249, P =0 001)while a negative relation between Zn and Mn(relative coefficient is -0 155, P <0 05)in boys’ hair.And,there is a negative relation between Fe and Mn(relative coefficient is -0 165, P <0 05)while a positive relation between Cu and Mn(relative coefficient is 0 181, P <0 05)in girls’ hair.更多还原
