摘要 蚊香烟雾是一类常见的影响人类健康的气溶胶。利用高分辨的静电扫描粒径谱仪,研究了实验室内外空气及室内蚊香燃烧产生的亚微米气溶胶(14~723nm)的粒径分布特征及衰减情况。实验表明,实验室内、外亚微米气溶胶的数浓度分别在1.09×104~4.45×104cm-3,1.15×104~3.56×104cm-3范围内。蚊香燃烧产生的亚微米气溶胶的数量中值粒径、表面积中值粒径及体积中值粒径分别为80nm、148nm和230nm。点燃蚊香15min产生的气溶胶恢复到背景水平需要1~2h。 Indoor combustion of mosquito coil generates smoke with submicron aerosol which is harmful to human by inhalation. This paper describes the determination of size distribution of this submicron aerosol along with the baseline (ambient and indoor) submicron particulates by using a high resolution particle sizer.
