随着机动车保有量的增加，与交通尾气有关的环境空气污染已成为我国重要的环境问题。由于儿童生长发育快，更容易受到环境空气污染的影响。交通尾气中的许多化学物质，如一氧化碳、二氧化氮和铅，已被报道对神经行为功能有不良影响。国内已有研究表明，交通尾气可能影响职业性交通尾气暴露者的神经行为功能。然而，很少有数据报告的影响，神经行为功能的儿童。本研究旨在探讨交通相关空气污染暴露与儿童神经行为功能的关系。本研究在中国泉州进行，根据交通密度和环境空气污染物监测数据选择两所小学。学校A位于清洁区，学校B位于污染区。2005年5月，我们连续2天在校园和教室内监测了NO2和气动直径≤ 10 μm的颗粒物作为交通相关空气污染指标。对两所学校的二年级（8-9岁）和三年级（9-10岁）儿童（n = 928）进行问卷调查和手工辅助神经行为测试。我们选择了282名三年级儿童（A学校，136人; B学校，146人）参加计算机辅助神经行为测试。我们在2005年5月至6月期间进行了实地调查。我们使用的数据来自861名参与者（学校A，431;学校B，430）与手动神经行为测试和所有参与者与计算机测试的数据分析。A校和B校的NO2浓度分别为7 μg/m3和36 μg/m3（p < 0.05）。有序逻辑回归分析表明，在控制潜在的混杂因素后，生活在污染区的参与者在所有测试中表现不佳; 9项测试中有6项（66.7%）的结果差异具有统计学意义：首选手和非首选手的视觉简单反应时间，连续性能，数字符号，追求瞄准和符号寄存器。我们发现慢性低水平交通相关空气污染暴露与暴露儿童的神经行为功能之间存在显着关系。需要更多的研究来探讨交通尾气对神经行为功能和发育的影响。
With the increase of motor vehicles, ambient air pollution related to traffic exhaust has become an important environmental issue in China. Because of their fast growth and development, children are more susceptible to ambient air pollution exposure. Many chemicals from traffic exhaust, such as carbon monoxide, nitrogen dioxide, and lead, have been reported to show adverse effects on neurobehavioral functions. Several studies in China have suggested that traffic exhaust might affect neurobehavioral functions of adults who have occupational traffic exhaust exposure. However, few data have been reported on the effects on neurobehavioral function in children. The objective of this study was to explore the association between traffic-related air pollution exposure and its effects on neurobehavioral function in children. This field study was conducted in Quanzhou, China, where two primary schools were chosen based on traffic density and monitoring data of ambient air pollutants. School A was located in a clear area and school B in a polluted area. We monitored NO2 and particulate matter with aerodynamic diameter ≤ 10 μm as indicators for traffic-related air pollution on the campuses and in classrooms for 2 consecutive days in May 2005. The children from second grade (8–9 years of age) and third grade (9–10 years of age) of the two schools (n = 928) participated in a questionnaire survey and manual-assisted neurobehavioral testing. We selected 282 third-grade children (school A, 136; school B, 146) to participate in computer-assisted neurobehavioral testing. We conducted the fieldwork between May and June 2005. We used data from 861 participants (school A, 431; school B, 430) with manual neurobehavioral testing and from all participants with computerized testing for data analyses. Media concentrations of NO2 in school A and school B campus were 7 μg/m3 and 36 μg/m3, respectively (p < 0.05). The ordinal logistic regression analyses showed that, after controlling the potential confounding factors, participants living in the polluted area showed poor performance on all testing; differences in results for six of nine tests (66.7%) achieved statistical significance: Visual Simple Reaction Time with preferred hand and with nonpreferred hand, Continuous Performance, Digit Symbol, Pursuit Aiming, and Sign Register. We found a significant relationship between chronic low-level traffic-related air pollution exposure and neurobehavioral function in exposed children. More studies are needed to explore the effects of traffic exhaust on neurobehavioral function and development.
