摘　　要：为研究不同因素对电子烟气溶胶中烟碱、羰基化合物等高度关注物释放量的影响,考察了功率、抽吸口数、甘油比例对烟碱、羰基化合物、TSNAs以及重金属释放量的影响。结果表明:①不同电子烟之间各种高度关注物的释放量差异较大,功率是影响电子烟气溶胶中高度关注物释放量的重要因素,随着功率的升高,烟碱、羰基化合物、TSNAs、重金属的释放量均增加;②羰基化合物释放量受功率的影响最为显著,随着功率的升高,羰基化合物的单位气溶胶捕集量(ACM)释放量增加,而烟碱、TSNAs的单位ACM释放量基本不变,重金属中Ni在功率80 W以上时单位ACM释放量基本不变;③抽吸口数对气溶胶中烟碱、羰基化合物、TSNAs的释放量均有影响,但高功率电子烟的重金属释放量在抽吸口数超过20口后基本不变;④甘油比例会影响电子烟气溶胶中羰基化合物的释放,甘油比例的增加会导致羰基化合物释放量快速增加,其中甲醛释放量的增加最为显著。In order to study the factors that influence the releases of interested components,such as nicotine,carbonyl compounds and other components from e-cigarette aerosols,the effects of device power,puffing number and glycerol ratio on the releases of nicotine,carbonyl compounds,TSNAs and heavy metals were investigated.The results showed that:1)The releases of the interested components differed significantly among different types of e-cigarettes.Device power was an important factor affecting the releases of various components from e-cigarette aerosols,the releases of nicotine,carbonyl compounds,TSNAs and heavy metals increased with the rise of device power.2)Device power influenced the releases of carbonyl compounds most significantly,the releases of carbonyl compounds on per unit aerosol collected mass(ACM)basis increased with the rise of device power,while those of nicotine and TSNAs were basically unchanged.The release of Ni on per unit ACM basis was largely unchanged when the device power was above 80 W.3)The releases of nicotine,carbonyl compounds and TSNAs from e-cigarette aerosols were affected by puffing number,however the releases of the heavy metals from high power device were basically unchanged when puffing number was higher than 20.4)Glycerol/PG ratio affected the releases of carbonyl compounds.The increase of glycerol/PG ratio accelerated the releases of carbonyl compounds rapidly,especially formaldehyde release.
