British scientists claim that on the surface of the smartphone bacteria 18 times more than the flush handle in a men’s public restroom. Fungus, mold, E. coli and other “known to science animals” can really get on the surface of the gadget that modern users often do not release from the hands. In the edition of Hi-tech.mail decided to sort out the problem and order your research. The results obtained NP “Ascontrol”, amazed the experts.
Does the result from the type of surface of the smartphone and the material from which made the housing? The experiment involved six popular models: the smooth metal of the iPhone 6, which is also metallic, but with a textured surface HTC One M8 glass Sony Xperia Z3, plastic Nokia Lumia 930 and LG G3 and Samsung Galaxy Note 4 with backrest from corrugated plastic.
In the study, microbiologists placed on the surface of the smartphone culture of pathogenic bacteria to see how it develops. For this purpose, the laboratory used, the slurry of the model organisms E. coli (Escherichia coli). The solution was applied on the surface of the smartphones with a sterile spray bottle. After processing, the gadgets were placed in a biological safety Cabinet – a special box with forced ventilation. A suspension of E. coli was dry there for 10 minutes. Then microbiologists took one flush with each smartphone, using every surface – front, rear and side.
The experiment showed that most comfortable Escherichia coli felt on the surface of the LG G3 is significantly worse on the iPhone 6. Third place was shared by the Nokia Lumia 930 and HTC One M8 and Sony Xperia Z3 and Samsung Galaxy Note 4 proved to be the most secure.
However, all smartphones withstood the experiment – the number of pathogens remaining on their surface, was many times less than that required for infection. Concentration of Escherichia coli even in the case of LG G3 is not statistically significant and is not dangerous.
The conclusion is clear: either foreign users rarely wash their hands, or British scientists have exaggerated the danger of smartphones to human health.
