| 摘 要： | 目的 考察不同功率条件下雾化器重复使用时电子烟气溶胶中Ni、Cr、As、Pb及Cu的释放规律。 方法 选取功率可调型电子烟6种，重复使用雾化器，连续3天检测不同功率下每20口气溶胶中重金属的释放量，分析其时间序列图。 结果 （1）低功率下，雾化器的重复使用对气溶胶中重金属的释放量均无明显影响；（2）高功率下，Ni、Cr的释放量随雾化器日内使用次数的增多而降低，As、Pb、Cu影响不明显；（3）在相同条件下，Ni、Cr、As、Cu的释放量随功率升高而增大，但Pb的释放量不随功率而变化。

| Abstract: | Objective In order to explore the effect of repeated use of atomizers on release amount of heavy metals in e-cigarette aerosols, and to investigate the release laws of Ni, Cr, As, Pb and Cu in e-cigarette aerosols when the atomizers are repeatedly used under different power conditions. Method Six types of electronic cigarettes with adjustable power were selected, the atomizer was repeatedly used, and the release amounts of heavy metals in every 20 aerosols under different powers were detected for 3 consecutive days, and the time series plots were analyzed. Results (1) Under low power, repeated use of the atomizer has no significant effect on the release amount of heavy metals in aerosols; (2) Under high power, the release amount of Ni and Cr decreases with the number of times the atomizer is used in a day. However, the influence on the release amount of As, Pb, Cu is not obvious; (3) Under the same conditions, the release amount of Ni, Cr, As, Cu increases with the increase of power, but the release amount of Pb does not change with power. |
