目的 :了解长期暴露于低水平镉环境 ,对儿童高级神经活动如学习、记忆的影响。方法 :选择某镉污染区 41名及与之相临的非污染区 44名 8～ 1 0岁小学男生 ,采用“韦氏记忆量表”进行记忆能力的测试。结果 :镉污染区学生记忆商为 72 .4±2 .2 5 ,低于对照区学生的 94.1 8± 1 .73 ,差异有高度显著性意义 (P <0 .0 1 )。反映长时记忆及短时记忆的量表分 ,污染区儿童比对照区低 ,而反映瞬时记忆的量表分 ,污染区儿童与对照区的差异无显著性意义 (P >0 .0 5)。结论 :长期镉摄入可损害儿童记忆能力 ,主要表现为长时记忆及短时记忆的损害 ,对瞬时记忆没有显著影响
Objective: To understand the long-term exposure to low levels of cadmium environment, high-level activities of children such as learning and memory. Methods: Forty-one primary school boys aged from 8 to 10 were selected from 41 cadmium-contaminated areas and non-contaminated areas adjacent to them, and the memory ability was measured using the Wechsler Memory Scale. Results: The memory of students in cadmium-contaminated area was 72.4 ± 2.52, which was lower than that of 94.1 8 ± 1.73 in control area, the difference was highly significant (P <0.01). Reflect the long-term memory and short-term memory of the scale points, children in the contaminated area lower than the control area, and reflect the instantaneous memory of the scale points, the contaminated area of children and the control area no significant difference (P> 0.05) . Conclusion: Long-term cadmium intake can impair children’s memory ability, which is mainly manifested as long-term memory and short-term memory damage, and has no significant effect on transient memory
