67名7岁的儿童在1到3岁之间没有症状地接触铅，他们在一系列心理测试中的表现与70名相同年龄和社会经济背景的儿童进行了比较，这些儿童可能没有明显的铅暴露。暴露在空气中的儿童在整体智商和联想能力、视觉和精细运动协调能力以及行为方面都存在缺陷。铅染毒组因学习和行为问题导致的学业失败的发生率高于对照组。
Sixty-seven 7-year-old children, who had asymptomatic lead exposure between 1 and 3 years of age, were compared in their performance on a series of psychologic tests to 70 children of the same age and socioeconomic background who presumably did not have significant exposure to lead. Exposed children had deficits in global IQ and associative abilities, in visual and fine motor coordination, and in behavior. School failure due to learning and behavior problems was more frequent in the lead exposed than in the control group.
