摘　　要：目的 :检测学习困难儿童的血铅水平 ,以分析儿童智力与血铅的关系。方法 :采用原子吸收分光光度法测定 30名学习困难、成绩差儿童 (实验组 )的血铅水平并与 30名学习无困难成绩优良学生 (对照组 )作比较。结果 :实验组的血铅水平为 138± 2 8μg/L ,明显高于对照组的 92± 18μg/L ,差异有非常显著性 (P <0 .0 1)。结论 :学习困难儿童的血铅水平升高 。Objective: To test lead level in blood of children with learning difficulty to investigate the relationship of children's intelligence and lead level in blood. Methods: Lead level in blood of 30 children (experimental group) with learning difficulty was measured using atomic absorption spectrophotometry, and then compared with that of 30 top students (control). Results: Lead level in blood of experimental group is 138±28 μg/L, much higher than that of control (92±18 μg/L). Their difference is significant(P<0.01). Conclusions: High level of lead in blood of children with learning difficulty indicates that lead has negative effect on children's intelligence.
