Rumor identification: Indoor smoking vinegar can not effectively kill the new coronavirus. Rumor analysis: 1, indoor smoked vinegar mainly uses vinegar, its acetic acid content is low, about 5%-8%, pH is about 2.9, and the new coronavirus can still survive in this environment. 2.Acetic acid evaporates into the air, the concentration is greatly reduced, and the space for enhancing the acidity of air is limited, so the fumigation vinegar cannot achieve the purpose of killing the new coronavirus. 3, some studies show that the new coronavirus is more sensitive to heat, 56 ℃ for 30 minutes, ether, 75% ethanol, chlorinated disinfectants, peroxyacetic acid and chloroform and other lipid solvents can be directly or through oxidation and other effects to make the new coronavirus inactive, to kill the purpose. Therefore, to kill the new coronavirus, 75% disinfectant alcohol or alcohol cotton tablets can be used more simple and easy. Special Note: Indoor vinegar smoking not only cannot kill the new coronavirus, but also the acetic acid in the air will stimulate the human respiratory tract, causing throat discomfort, nausea, breathing difficulties and other discomforts. Therefore, the public home disinfection can be used to choose the common 84 disinfectant (containing chlorine disinfectant) wipe common furniture, such as tables, door handles, chairs, floors, doors, toilet rings, etc., and disinfection should be no less than 30 minutes, and then wipe clean with water. In addition, it should be noted that disinfection is recommended to wear masks and gloves for operation.
