摘要:
为考察功率和抽吸容量对电子烟气溶胶中重金属释放量的影响,以可填充式雾化器和自主配制的电子烟液为对象,分析了不同功率和抽吸容量下气溶胶中6种重金属(Cr、Ni、Cu、As、Cd和Pb)释放量。结果表明:①气溶胶中没有检出As和Cd元素;②功率对气溶胶中Cr、Ni和Cu释放量有显著影响,对Pb释放量影响不显著;③抽吸容量对气溶胶中Cr、Cu和Pb元素释放量有显著影响,抽吸容量大于75 mL时对Ni释放量有显著影响;④功率对气溶胶中Ni和Cu元素释放量的贡献大于抽吸容量,功率对气溶胶中Cr和Pb元素释放量的贡献小于抽吸容量。

Abstract:
To study the effects of device power and puffing volume on selected heavy metal emissions in e-cigarette aerosols, six heavy metals (Cr, Ni, Cu, As, Cd and Pb) and their concentrations in the aerosols of e-cigarettes at different device powers and puffing volumes were analyzed by using refillable atomizers and self-prepared e-liquids. The results showed that:1) As and Cd were not detected in the aerosols. 2) Device power had significant effects on the Cr, Ni and Cu emissions in the aerosols, however no obvious effect was observed for Pb. 3) Puffing volume had significant effects on the Cr, Cu and Pb emissions in the aerosols, and significant effects were observed for Ni when puffing volume was larger than 75 mL. 4) Device power had more significant effects on Ni and Cu emissions in the aerosols than puffing volume, however, the reverse was true for Cr and Pb emissions in the aerosols.
