ICoronavirus kunye nomkhuhlane iintsholongwane zivakalelwa kwiasidi ye-aerosol. I-pH-mediated ukungasebenzi ngokukhawuleza kwe-coronavirus kunokwenzeka ngokutyebisa umoya wangaphakathi ngamanqanaba angeyongozi e-nitric acid. Ngokuchaseneyo, isihluzo somoya wangaphakathi sinokususa ngempazamo iiasidi eziguqukayo ngaloo ndlela sandise ukuzingisa kokuhamba emoyeni. intsholongwane. Oku kuqonda okutsha kunokuba luncedo kakhulu ekulawuleni ukuhanjiswa emoyeni ngokukodwa kwindawo yangaphakathi efana nezicwangciso zesibhedlele.
Usulelo lokuphefumla olubangelwa umkhuhlane kwaye iintsholongwane ze-corona ziingxaki ezinkulu eziqhubekayo kwimpilo yabantu. Umkhuhlane wodwa ubangela ukufa kwabantu abangaphezu kwama-400,000 ngonyaka kwihlabathi liphela. Ubhubhani we-COVID-19 oqhubekayo kubangelwe inoveli coronavirus I-SARS CoV-2 ibangele ukufa kwabantu abangaphezu kwezigidi ezi-6 ukuza kuthi ga ngoku kunye nokubandezeleka okukhulu kwabantu kunye nomonakalo ongenakucingelwa wezoqoqosho kuqoqosho lwehlabathi. Ngoko ke, kuncitshiswe ukuhanjiswa kwezi iintsholongwane yeyona nto ibalulekileyo ephambili.
Kuyaziwa ukuba eyona ndlela ibalaseleyo yosulelo yeyomoya. Olu sulelo lufumaneka ngokuphefumla umoya ongcolileyo. Amasuntswana e-aerosol aphelelwa lixesha asebenza njengezithuthi zokusasaza umkhuhlane intsholongwane kunye noveli intsholongwane ye-Corona I-SARS-CoV-2. Kungoko ukubaluleka kokunxiba izigqubuthelo zobuso. Kucingelwa ukuba i intsholongwane inokuhlala emoyeni malunga neeyure ze-3 kunye nesiqingatha sobomi beeyure ze-1.1.
Akufuneki ukuthetha, ukuba ukungasebenzi ngokukhawuleza kwezi iintsholongwane ziya kuba negalelo elikhulu ekuthinteleni usulelo lwazo.
Kuyaziwa ukuba igubungele iintsholongwane njengomkhuhlane kunye umqhele iintsholongwane ayasebenza phantsi kweemeko ezineasidi kodwa inqanaba leasidi yamasuntswana e-aerosol ephefumlayo kunye nendima yawo ekuvuleleni ukusebenza iintsholongwane ebengaziwa.
Kuphononongo lwakutsha nje olupapashwe kwi-preprint medRxiv, abaphandi bavavanye lo mba womkhuhlane kunye nomkhuhlane. iintsholongwane ze-Corona. Baye bafumanisa ukuba iincinci ze-aerosol ezikhutshwe emoyeni wangaphakathi ziba ne-acidic epholileyo (pH ≈ 4). Le meko eneasidi yayeka ukusebenza ngokukhawuleza umkhuhlane-A intsholongwane phakathi kwemizuzu kodwa inoveli intsholongwane ye-Corona I-SARS-CoV-2 iintsuku ezifunekayo zokungasebenzi. Ngaphaya koko, ukuba umoya wangaphakathi uye watyetyiswa ngamanqanaba angeyongozi e-nitric acid, ubumuncu be-aerosol buye behla ukuya kuthi ga kwiiyunithi ezi-2 ezithe zanciphisa amaxesha okungasebenzi kuzo zombini. iintsholongwane ukuya ngaphantsi kwemizuzwana engama-30. Oku kuncitshiswa kwe-pH-mediated 99% - ukuncitshiswa kwexesha lokungasebenzi kunokubaluleka kakhulu ekuqaliseni ukusebenza ngokukhawuleza kwezi. iintsholongwane kwiindawo zangaphakathi ngaloo ndlela inceda ukunciphisa ukusasazeka koluntu kakhulu.
Ngokukhanya okufunyenwe ngasentla, ukusetyenziswa kwezihluzo zomoya zangaphakathi kufuneka kuqwalaselwe ngononophelo kuba nakuphi na ukususwa ngempazamo kweeasidi eziguquguqukayo kumoya wangaphakathi kunokunciphisa ubumuncu be-aerosol ephefumlayo kwaye kwandise ixesha lokuphuma emoyeni. intsholongwane ukuzingisa.
