摘　　要：目的:探讨高铬暴露是否影响儿童正常的神经行为发育。方法:采用石墨炉原子吸收光谱法,检测贵屿镇225名3～7岁儿童静脉血血铬浓度;通过Conners父母症状问卷、Conners教师问卷(TRS)及自制调查表问卷了解儿童的行为状况并分析相关影响因素。结果:贵屿镇儿童血铬均值为(174.3±11.0)μg/L,儿童血铬水平受母亲从事电子垃圾拆解相关工作及时间长短的影响;TRS各行为因子得分,女童高铬组与低铬组比多动指数得分存在差异,血铬值与TRS中的品行问题、多动问题、不注意-被动、多动指数的得分正相关。结论:电子垃圾拆解区的铬污染可以通过影响儿童的血铬水平,而影响儿童的神经行为发育。Objective： To explore if chromium exposure can affect normal neurobehavioral development of children.Methods： Two hundred and twenty-five children aged from 3 to 7 lived at Guiyu town were selected as subjects.The chromium level of venipuncture blood samples was determined with graphite atomizer absorption spectrophotometer.Parents and teacher were asked to fill out Parent Symptom Questionnaire and Teacher Rating Scale（TRS）to investigate the children behavior problem.Questionnaires for parents were used for analysis of related factors.Results： Children＇s blood chromium level mean was（174.3±11.0）μg/L.Mother involving in e-waste dismantling work and time of engaged in the work affected children blood chromium level.High chromium group children had higher scores than low chromium group of hyperactivity index of TRS in girls.The children blood chromium levels were positively correlated with behavior factor scores of conduct problems,inattentive,impulsivity-hyperactivity and hyperactivity index of TRS.Conclusion： Chromium pollute in electronic waste recycling area affects blood chromium level of children,which might impede the children＇s neurobehavior development.
