使用气溶胶监测器对二手电子烟（ECIG）气溶胶暴露的研究表明，ECIG的使用会产生高浓度的颗粒物（PM），并影响室内空气质量。然而，量化室内空气PM浓度使用实时光学监测器与现场校准，专门为不同的PM暴露尚未建立。因此，ECIG气溶胶过滤器的校正因子是针对不同的PM尺寸（PM 1、PM2.5和PM10）和不同的气溶胶光学监测器（MiniWRAS、pDR和SidePak）计算的。ECIG气溶胶生成实现了使用五个ECIG代表三种ECIG类型，一次性，豆荚国防部，和箱国防部。气溶胶粒径分布的质量进行了测量的五个ECIG在PM生成。与离散过滤器测量相比，当浓度较低时，MiniWRAS的性能最佳，其次是pDR和SidePak。不同ECIG的平均PM浓度和校正因子范围分别为：MiniWRAS为323- 1，775 μg/m3和0.64-6.01，pDR为1，388 - 13，365 μg/m3和0.41-0.80，SidePak为4，632 - 55，339 μg/m3和0.13-0.20。质量中位直径范围为0.41 - 0.62 μm，并且大多数由ECIG产生的颗粒小于1 μm。这项研究表明，气溶胶粒径分布的ECIG之间的变化。同样，为实时气溶胶监测器开发的校正因子是特定于所使用的ECIG的。因此，这些数据可以帮助提高ECIG气溶胶暴露测量精度。
Research on secondhand electronic cigarette (ECIG) aerosol exposure using aerosol monitors has demonstrated that ECIG use can generate high concentrations of particulate matter (PM) and impact indoor air quality. However, quantifying indoor air PM concentrations using real-time optical monitors with on-site calibration specifically for different PM exposures has not been established. Therefore, the ECIG aerosol filter correction factors were calculated for different PM sizes (PM1, PM2.5, and PM10) and different aerosol optical monitors, the MiniWRAS, pDR, and SidePak. ECIG aerosol generation was achieved using five ECIGs representing three ECIG types, disposable, pod-mod, and box mod. The aerosol size distribution by mass was measured for the five ECIGs during PM generation. Compared to the discrete filter measurements, the MiniWRAS performed the best when the concentrations were low, followed by the pDR and SidePak. The average PM concentrations and correction factor ranges for the different ECIGs were 323-1,775 μg/m3 and 0.64-6.01 for the MiniWRAS, 1,388-13,365 μg/m3 and 0.41-0.80 for the pDR, and 4,632-55,339 μg/m3 and 0.13-0.20 for the SidePak, respectively. The mass median diameter ranged from 0.41 and 0.62 μm, and most particles generated from the ECIGs were smaller than 1 μm. This study demonstrates that aerosol size distribution varies between ECIGs. Likewise, the correction factors developed for the real-time aerosol monitors are specific to the ECIG used. Thus, these data can help improve ECIG aerosol exposure measurement accuracy.
