摘 要:为了解安庆市不同类型商场中甲醛的污染现状,对位于安庆市的5家大型商场50个点进行了为期5天的室内空气质量检测,对所得数据进行整理分析,得出如下结论:(1)服装商场甲醛含量最高达0.19 mg/m3,超标率10%。(2)家具商场甲醛含量0.03~0.10 mg/m3,超标率10%。(3)电器、食品、饮食方面甲醛含量相对较低,其平均浓度为0.032 mg/m3,超标率分别为0%,0%,10%。(4)相关性分析表明,温度高的采样点甲醛含量相对较高。此外,甲醛浓度还受通风、装修时间等因素的影响。To analyze the formaldehyde's pollution,its source and improving air quality in shopping mall in Anqing,Anhui Province,fifty samples from 5 shopping malls are collected in five days. The results show that( 1) the maximal concentrations of formaldehyde in all clothing store samples is 0. 19 mg / m3 with exceeding standard rate of 10%,( 2) the concentrations of formaldehyde in all furniture store samples is from 0. 03 to 0. 10 mg / m3 with exceeding standard rate of 10%,( 3) the concentration of formaldehyde in electrical equipment,eating and foods stores is relatively low,with average levels of 0. 032 mg / m3,and with exceeding standard rate of 0%,0% and 10%,respectively,( 4) the higher levels exist in samples with higher temperature. And the concentration of formaldehyde is influenced by humidity,wind and ventilation rate. Finally,the proposals of improving air quality in malls are giving based on our research.
