摘要

为了比较点燃一圈蚊香和一包香烟所产生的PM2．5的浓度大小，选择两间面积约为16平米且可密闭的房间作为试验场地，按照《HJ/T194-2005环境空气质量手工监测技术规范》连续12小时采样分析，结果发现点一圈蚊香的房间里PM2．5的浓度约是点一包香烟的房间PM2．5的浓度的2倍。%In order to compare the PM 2.5 concentration of Liting a mosquito -repellent incense and cigarette , choose two area of about 16 square meters and can be close rooms as laboratory , According to Ambient air quality monitoring technical specification by hand , Through sampling analysis for 12 hours, The results showed that liting a mosquito -repellent incense of PM2.5 concentrations in the room is about double of the liting cigarette room PM 2.5 concentrations .
