对昆明市儿童及青少年共２１３人进行了智商测定，以头发为样品，测定了Ｐｂ、Ｃｄ、Ｃｒ、Ｃｏ、Ｎｉ、Ｍｎ、Ｃｕ、Ｆｅ、Ｚｎ、Ｋ、Ｎａ、Ｃａ、Ｍｇ和Ｐ的含量，以上述测定值及Ｚｎ／Ｃｕ、Ｃａ／Ｍｇ、Ｎａ／Ｋ、年龄、性别等１９项指标为自变量，用Ｆ浮动法进行多元逐步回归，筛选出对智商影响较明显的因素为Ｚｎ、Ｃｕ、Ｃｏ、Ｃｒ、Ｍｎ，其次为Ｃｄ及Ｎａ。提示各元素间的协同作用和拮抗作用对智力产生综合影响。

A total of 213 children and adolescents in Kunming were tested for IQ, hair samples were used to determine the contents of Pb, Cd, Cr, Co, Ni, Mn, Cu, Fe, Zn, K, Na, Ca, Mg and P , The above measured values ​​and 19 indexes such as Zn / Cu, Ca / Mg, Na / K, age and gender were taken as independent variables. The multiple stepwise regression was carried out by using the F floatation method. Cu, Co, Cr, Mn, followed by Cd and Na. Suggesting that synergy and antagonism of the various elements of the comprehensive impact on intelligence.
