室内老化蒸汽气溶会产生有金属和自由基的有害颗粒, 尤其当暴露在臭氧和肺液中时, 可能会恶化喘和慢性肺炎等呼吸系统疾病. Aged vape aerosols indoors produce harmful particles with metals and free radicals, especially when exposed to ozone and lung fluid, potentially worsening respiratory conditions like asthma and COPD.

一项新研究发现，陈年蒸汽气溶胶留在室内时，可能产生含有金属和活性自由基的有害超细颗粒，尤其是在暴露于臭氧和肺液时。 A new study finds that aged vape aerosols left indoors can produce harmful ultrafine particles containing metals and reactive radicals, especially when exposed to ozone and lung fluid. 这些颗粒随着时间推移形成,每单位重量产生的自由基数比较大的颗粒多100倍,并可能损害肺组织,对哮喘或肺炎患者构成更大的风险。 These particles, which form over time, generate 100 times more free radicals per unit weight than larger particles and may damage lung tissue, posing greater risks to those with asthma or COPD. 虽然在实验室中使用简化电子液体,但研究结果表明二手电子烟暴露 - - 特别长时间使用 - - 可能会损害呼吸系统健康,因此需要更多实践研究和公众意识. Though conducted in a lab with simplified e-liquids, the findings suggest secondhand vape exposure—particularly prolonged—could harm respiratory health, prompting calls for more real-world research and public awareness.
