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 investigate the influence of interior decoration pollution on children’s peripheral blood. Methods In June 2011, 200 schoolchildren from grade 2 to grade 4 (7 to 9 years old) in five primary schools in Tai’an City were selected, including 105 males and 95 females. According to whether there is any decoration at home in one year or not, Each of the 100 renovated units was monitored for the indoor pollutants formaldehyde, benzene and total volatile organic compounds (TVOC). Results The abnormal rates of RBC, Hb, WBC and Plt in peripheral blood were 15.00%, 20.00%, 11.00% and 6.00% respectively in the decoration group and 4.00%, 6.00%, 1.00% and 0 in the unmodified group respectively (3.88 ± 0.30) × 1012 / L, Hb (115.60 ± 9.81) g / L, and WBC (5.72 ± 2.59) in the renovated group (all P <0.05) ) × 109 / L, Pl (t 140.60 ± 43.84) × 109 / L were significantly higher than those of non-standard children (all P <0.05). Conclusion Indoor decoration pollution, especially indoor benzene exposure on children’s peripheral blood have a certain impact.
