Tooj liab yog cov khoom siv tshuaj tua kab mob zoo tshaj plaws rau qhov chaw.
Tau ntau txhiab xyoo, ntev ua ntej lawv paub txog kab mob lossis kab mob, tib neeg tau paub txog tooj liab lub zog tshuaj tua kab mob.
Thawj zaug sau tseg siv tooj liab los ua tus kab mob tua neeg los ntawm Smith's Papyrus, cov ntaub ntawv kho mob qub tshaj plaws hauv keeb kwm.
Raws li rov qab mus txog 1,600 BC, Suav tau siv nyiaj npib tooj liab los kho mob plawv thiab mob plab nrog rau cov kab mob zais zis.
Thiab tooj liab lub zog kav ntev.Keevil pab pawg tau tshuaj xyuas cov kab qub qub ntawm New York City's Grand Central Terminal ob peb xyoos dhau los."Lub tooj liab tseem ua haujlwm zoo li nws tau ua hnub nws tau muab tso rau hauv ntau dua 100 xyoo dhau los," nws hais."Cov khoom no tau ruaj khov thiab cov nyhuv anti-microbial tsis ploj mus."
Nws ua haujlwm raws nraim li cas?
Copper qhov tshwj xeeb atomic pleev muab nws ntxiv zog tua.Tooj liab muaj ib tug dawb electron nyob rau hauv nws sab nrauv orbital plhaub ntawm electrons uas yooj yim koom nyob rau hauv oxidation-txo cov tshuaj tiv thaiv (uas kuj ua rau cov hlau ib tug zoo conductor).
Thaum cov microbe tsaws rau ntawm tooj liab, ions tawg cov kab mob zoo li kev tawm tsam ntawm cov cuaj luaj, tiv thaiv kev ua pa ntawm tes thiab xuas nrig ntaus qhov hauv cov cell membrane lossis kab mob txheej thiab tsim cov dawb radicals uas ua rau tua, tshwj xeeb tshaj yog nyob rau ntawm qhov chaw qhuav.Qhov tseem ceeb tshaj plaws, cov ions nrhiav thiab rhuav tshem DNA thiab RNA hauv cov kab mob lossis kab mob, tiv thaiv kev hloov pauv uas tsim cov kab mob tshuaj tiv thaiv super.
COVID-19 puas tuaj yeem muaj sia nyob ntawm qhov chaw tooj liab?
Ib txoj kev tshawb nrhiav tshiab tau pom tias SARS-CoV-2, tus kab mob ua rau tus kab mob corona-tus kab mob kis thoob qhov txhia chaw, tsis kis rau tooj liab li ntawm 4 teev, thaum nws tuaj yeem muaj sia nyob ntawm cov yas yas rau 72 teev.
Tooj liab muaj cov tshuaj tua kab mob, txhais tau tias nws tuaj yeem tua cov kab mob xws li kab mob thiab kab mob.Txawm li cas los xij, cov kab mob microorganisms yuav tsum tau sib cuag nrog tooj liab kom nws tua.Qhov no yog hu ua "kev sib cuag tua."
Kev siv cov tshuaj tua kab mob tooj liab:
Ib qho ntawm cov kev siv tseem ceeb ntawm tooj liab yog nyob rau hauv tsev kho mob.Qhov chaw germiest nyob rau hauv chav tsev kho mob - txaj rails, hu khawm, lub rooj zaum caj npab, lub rooj tais, cov ntaub ntawv nkag, thiab IV ncej - thiab hloov lawv nrog tooj liab Cheebtsam.
Piv nrog rau cov chav ua nrog cov ntaub ntawv ib txwm muaj, muaj 83% txo cov kab mob hauv cov chaw hauv cov chav nrog tooj liab.Tsis tas li ntawd, kev kis tus kab mob ntawm cov neeg mob tau txo los ntawm 58%.
Cov khoom siv tooj liab kuj tseem tuaj yeem pab tau zoo li cov tshuaj tua kab mob hauv cov tsev kawm ntawv, kev lag luam khoom noj, chaw ua haujlwm tsev so, tsev noj mov, tsev txhab nyiaj thiab lwm yam.
