摘　　要：本实验对某铅作业工厂的子校学生进行了智力发育的调查。根据其父母接触铅的程度分为实验一组（父母双方均接触铅或有一方接触铅）、实验二组（父母不接触铅）及对照组３个组，调查总数为１８３名。结果表明：实验一、二组学生血铅（ＰｂＢ）值增高，其智商有降低趋势。父母接触组学生低智商检出率较高（Ｐ＜０．０５）。母亲为铅作业者的学生智商显著低于对照组（Ｐ＜０．０５）。当ＰｂＢ≥０．９７μｍｏｌ／Ｌ时，智商有降低趋势。经逐步回归分析表明铅是影响智商的因素之一。study of intellectual development of students in a school situated in a lcad pollected factory wascarried out.One hundred and eighty-three exposure degree of their parents,Students whose parentswere expoSured to lead were in the test group I. While students where parents didn′t exposure to leadwere in the test group.And the third one was control group.The results showed that blood lead levelwad high both in the test group 1 and 2,and their intellectual quotient had a higher in the group 1 thatin the group2(P<0.05).The students intellectual quotient is more lower in the group whose motheris a lead worker(P<0. 05).The intellectual quotient student had a low tendency when the blood lev-el wad equal or higher than the level of 0. 97μmol/L,The ultiple lincar regression results showed thatthe lead is one of effective factors to in tellectual quotient.
