【摘要】 为了解学龄前儿童智商与血中微量元素含量之间的关系 ,本文测定了佛山市幼儿园 576名 4～ 6岁儿童的IQ值及其血中六种元素 (Zn、Fe、Cu、Ca、Mn、Pb)的含量 ,并对幼儿血中微量元素含量与IQ值的关系进行了探讨。结果表明 ,低智商儿童血中锌含量显著低于高智商儿童血中锌含量 ,而血铅则显著高于高智商儿童的血铅。说明学龄前儿童智商高低与机体锌及铅的含量有密切关系。更多还原

【Abstract】 In order to find out the relations between intelligence quotient(IQ)of preschool children and the content of trace elements in blood,the IQ of 576 children at 4 to 6 years old and the content of trace elements(Zn,Fe,Cu,Ca,Mn,Pb)in blood in Foshan city was determined.The relationship between IQ and the content of those elements in blood was discussed.The result showed that the content of Zn in blood of children with low IQ was lower than that of children with high IQ.The content of Pb in blood of children with low IQ was higher than that of the latter.It indicates that there are close relations between children’s IQ and the content of Zn and Pb in organism.更多还原
