【摘要】：目的探讨学龄前儿童PM2.5暴露与行为问题的关系。方法于2013年4—9月采用分层抽样抽取深圳市某区22个幼儿园,对中班教室、幼儿起居室、玩具室等37个场所的PM2.5水平进行监测。采用Achenbach儿童行为量表调查幼儿园中班1290名学龄前儿童行为问题情况。结果儿童行为问题检出率为17.67%,儿童PM2.5个体暴露平均值为113μg/m3,最高值达206μg/m3。男童攻击性、违纪得分和总分与PM2.5水平呈正相关(β值分别为0.207,0.161,0.118;P0.05);女童抑郁、分裂样、多动得分及总分与PM2.5水平呈正相关(β值分别为0.126,0.171,0.150,0.143;P0.05)。结论环境PM2.5暴露与学龄前儿童行为问题关系密切。
[Abstract]:Objective to explore the relationship between PM2.5 exposure and behavioral problems in preschool children. Methods A stratified sampling was used to select 22 kindergartens in a district of Shenzhen from 2013 to September. The level of PM2.5 was monitored in 37 places such as toy room. The behavior problems of 1290 preschool children in middle class of kindergartens were investigated by Achenbach children behavior scale. Results the behavior of children was asked. The detection rate was 17.67%. The average value of individual exposure to PM2.5 in children was 113 渭 g / m ~ (3), and the highest value was 206 渭 g / m ~ (3). Boys were aggressive. The score and total score of violation of discipline were positively correlated with the level of PM2.5 (尾 = 0.207 0. 161 卤0. 118); P0.05; The scores of depression, split-like, hyperactivity and total score were positively correlated with the level of PM2.5 (尾 = 0.126 0. 171 卤0. 150 卤0. 143). Conclusion Environmental PM2.5 exposure is closely related to preschool children's behavioral problems.

【正文快照】： 大气中对人体有潜在危害的物质(如重金属、PAHs等)主要吸附于PM2.5,而在粗颗粒物(PM10~2.5)中的含量较少[1],S、Br、Cl、As、Se、Cu、Pb、Zn等8种元素在PM2.5中易富集,其中S、Pb、Se可富集数千倍[2]。近年来,北京、广州、哈尔滨等大城市PM2.5污染日益严峻,儿童呼吸系统疾病明
