(伦敦8日综合电)英国科学家麦克拉伦近日透过实验发现,公共厕所烘手机吹出的强风中充满细菌与真菌,经过一夜培养后,培养皿长出大量不同种类的细菌。相较之下,一般空气中的细菌含量几乎为零。
麦克拉伦是Devon Science教育计划创办人,先前在TikTok上分享这项实验过程,她将培养皿放置于公共厕所烘手机下方,收集吹出的空气样本,同时另取一个培养皿在一般空气中挥动作为对照组,经过隔夜培养后,结果令人震惊。
麦克拉伦在影片中表示,烘手机培养皿出现许多不同种类的细菌,甚至还有真菌,相对之下,一般空气样本完全没有细菌生长,这项结果令她直言,“这就是我不用烘手机的原因”,引发网友热议。

这段影片在社媒上疯传,累积逾千万次观看。
有网友留言回应,“我以后宁愿用衣服或纸巾擦手”、“烘手机不是高温吗?怎么还会有细菌,甚至真菌?”,甚至有网友笑称:“身为一个多年来一直宣传烘手机很脏的人,我觉得自己不那么疯狂了”。
不过,也有部分网友指出实验方法存在争议,认为应采集公厕空气作为对照组才更具说服力。麦克拉伦也承认这点,并称将进一步进行相关测试。
@devonscience Has anything changed? Did that hand dryer get a service or clean? For its viral birthday 🎉 (28M views), I went back and retested THE hand dryer seen by so many, this time I also tested my hands before & after using it. I’ve identified the main bacterial species growing (they’re common environmental bacteria), and they’re coming from inside the machine vents (see videos on this). Please see my follow up videos on this which will answer some of your questions, i.e. are the bacteria harmful, what do these results mean, what happens next! Remember this is a quick test, not a scientific experiment, but it could be a great project for someone studying microbiology. I’ve tested a few different hand dryers over the last 12 months, have a look at the videos on my profile. #handdryer #bacteria #viral #germs #dirty ♬ original sound – Devon Science
