According to the 2018 US Census, smartphones are present in 85% of American households. It is reported to be viewed 14 million times a day, making it a potential reservoir for environmental hazards such as allergens. A new study presented at this year’s American Society of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Louisville, Kentucky, showed increased levels of allergens in cats and dogs. β– Simulated phone model D-glucan (BDG) and endotoxin.
“Smartphones showed elevated and fluctuating levels of BDG and endotoxin. We also found cat and dog allergens in smartphones of pet owners,” said the study’s lead author. Hana Ruran says. “BDG is found in the cell walls of fungi, is found on many environments and surfaces, and causes chronic respiratory tract and irritative symptoms, making it a consistent marker for studying problematic molds. Endotoxins are potent inflammatory agents and markers of Gram-negative exposure.”
The researchers created a phone model with a similar size and surface to a real phone and wiped the front of the phone model as part of the test. Using electrostatic wipes (ESW), we sampled a simulated phone model of 15 volunteers and measured ‘phone’ allergen, BDG and endotoxin levels.
(Chlorhexidine, cetylpyridinium chloride, tannic acid, benzyl benzoate) The chemicals used in the cleaning mixture can be purchased from a laboratory or chemical supplier, but should be kept in the same concentration as used in the study. not commercially available. The cleaning properties of isopropyl alcohol wipes were also tested.
“The chlorhexidine/cetylpyridinium combination was the most effective at reducing BDG and endotoxin, and the benzyl benzoate/tannic acid combination was the most effective at reducing smartphone cat and dog allergens,” said Dr. Dr. Peter Thorne, professor of public health at the University of Iowa, said. – Study author. “This study shows exposure to inhaled allergens and molecules that trigger innate immune responses from sources most people would never have thought of. We recommend that you consider cleaning your smartphone more frequently to minimize exposure.”
