摘　　要：目的探讨室内装修污染对儿童外周血象的影响。方法 2011年6月选取泰安市城区五所小学的2～4年级(7～9岁)学龄儿童200名,其中,男105名,女95名,按1年内家里有无室内装修分为装修组和无装修组各100名,进行室内污染物甲醛、苯及总挥发性有机物(total volatile organic compounds,TVOC)指标的监测。结果外周血象RBC、Hb、WBC、Plt异常率:装修组分别为15.00%、20.00%、11.00%和6.00%;未装修组分别为4.00%、6.00%、1.00%和0,两组比较差异均有统计学意义(均P<0.05);装修组苯浓度超标家庭儿童的外周血象各项指标RBC(3.88±0.30)×1012/L、Hb(115.60±9.81)g/L、WBC(5.72±2.59)×109/L、Pl(t 140.60±43.84)×109/L与未超标家庭儿童比较差异均有统计学意义(均P<0.05)。结论室内装修污染尤其室内苯暴露对儿童的外周血象有一定的影响。Objective To discuss the influence of indoor decoration pollution on peripheral hemogram in children. Methods An investigation was conducted among 200 children（aged 7- 9 years, grade 2-4） from five primary schools in Taian on their home deco- ration in June 2011. There were 105 boys and 95 girls. Depending on whether they had decoration in their room in a recent year, they were randomly divided into two groups： decoration group （n=100） and undecoration group （n=100）. Meanwhile, indoor air pollution by formaldehyde, benzene and total volatile organic compounds （TVOC） was monitored. Results The abnormal rate of peripheral hemogram such as RBC, HB, WBC and PLT was 15.00%, 20.00%, 11.00% and 6.00% respectively in decoration group, and 4.00%, 6.00%, 1.00% and 0 respectively in undecoration group; and there was significant difference between the two groups （all P 〈 0.05）. Compared with the children living in a room without benzene exceeding, the values of peripheral hemogram were significantly lower in children living in a room with benzene exceeding standard limit [RBC（3.88 ± 0.30） × 10^12/L, HB（115.60 ± 9.81）g/L, WBC （5.72± 2.59） × 10^9/L and PLT （140.60 ±43.84） × 10^9/El. Conclusion Indoor decoration pollution, especially exposure of indoor benzene has a certain effect on peripheral hemogram in children.
