电子烟消费者抽吸参数研究进展

Research progress on puffing behaviors of e-cigarette users

综述了国内外电子烟抽吸参数研究方法、研究结果、影响因素等。现有文献研究表明,电子烟抽吸参数可能与多种因素相关,包括使用经验、产品类型、烟液烟碱浓度、抽吸环境、雾化器功率、烟液口味和溶剂等。但现有研究数量有限,不同研究结果也存在较大差异,考虑到将来电子烟产品的管制及消费者有害成分暴露风险评估,抽吸参数的研究如大量人群的自然抽吸行为、抽吸参数影响因素(特别是产品设计,包括电池、通风设置、烟液组成等)仍需进一步深入进行。

Published research methods,results,and potential influence factors of puffing parameters of e-cigarette users were reviewed.At present,the reported literature showed that the puffing parameters of e-cigarette users correlated to a variety of factors,including puffing experience,product types,nicotine concentrations in e-liquids,usage environment,atomizer power,flavor types of e-liquids,solvent or aerosol agents,etc.However,the number of existing studies was limited,and there were great differences among the results of the different studies.Considering the need for suitable regulation of e-cigarettes and the risk assessment of potential harmful component exposure of their users and bystanders in the future,the research on puffing behaviors with a large-scale,better controlled volunteers under natural puffing environment and other defined factors,especially product design variables(including battery capacity,ventilation setting,liquid composition,etc.),influencing puffing parameters,still need to be further studied.
