摘要
目的探讨汽车尾气污染以及其他因素对儿童神经行为功能的影响。方法整群抽取北京市机动车尾气暴露程度不同地区两所小学的三、四年级的儿童。在知情同意的前提下,进行问卷调查、儿童个体暴露水平监测以及计算机化神经行为评价系统(NES)测试儿童的神经行为功能,用Answertree软件分析。结果儿童神经行为功能受母亲文化程度、个体碳氧血红蛋白水平、个体SO2暴露水平等因素的影响。结论母亲文化程度为高中、中专或者大专,个体碳氧血红蛋白水平及SO2暴露水平较高的儿童神经行为功能最差,是应给予关注并主要保护的人群。
Objective To explore the latent neurobehavioral function impairments by traffic exhausts and other factors on the children. Methods Two primary schools were chosen according to the air quality report in Beijing. School B is located at seriously exhausts polluted area while school A is at less polluted area, All children in grade three and grade four were selected as our objects. The survey was conducted based on the agreement of the children＇ s parents, NES was employed to measure the children＇ s neurobehavioral functions while the 24 hour NO2 and SO2 personal exposure levels, Zinc Protoporphyrin（ZZP） and CO levels in expiration gas were measured, Then, Answertree was used. Results It is indicated that neurobehavioral functions of children were associated with the education level of children＇ s mothers, children＇s personal COHb levels and personal SO2 exposure levels. Conclusion The children, whose mothers＇ education level were middle, with high personal COHb levels and SO2 exposure levels were the high risk population.
