Mufananidzo weBanner: Chiedza cheultraviolet kubva pakrypton chloride excimer rambi chinofambiswa nemamorekuru anofamba pakati penzvimbo dzakasiyana dzesimba.(Kwakabva: Linden Research Group)
Tsvagiridzo nyowani kubva kuYunivhesiti yeColorado Boulder yakaona kuti mamwe mawavelengths eultraviolet (UV) mwenje haangoite zvakanyanya pakuuraya hutachiona hunokonzera COVID-19, asi zvakare akachengetedzeka kushandisa munzvimbo dzeveruzhinji.
Chidzidzo ichi, chakaburitswa mwedzi uno mugwaro reApplied and Environmental Microbiology, ndiyo yekutanga kuongororwa kwakadzama kwemhedzisiro yemawavelengths akasiyana e ultraviolet mwenje paSARS-CoV-2 nemamwe mavhairasi ekufema, kusanganisira iwo chete akachengeteka kune zvipenyu uye. haidi kuonana wavelengths.Dzivirira.
Vanyori vanodana zvakawanikwa izvi "shanduko yemutambo" yekushandiswa kwemwenje weUV iyo inogona kutungamira kune itsva inotengeka, yakachengeteka uye inoshanda masisitimu ekudzikisa kupararira kwehutachiona munzvimbo dzakazara veruzhinji dzakadai senhandare dzendege nenzvimbo dzemakonzati.
"Pakati pezvirwere zvese zvatakadzidza, hutachiona uhu ndihwo huri nyore kuuraya nechiedza cheultraviolet," akadaro munyori mukuru Carl Linden, purofesa weinjiniya yezvakatipoteredza.“Zvinoda mishonga yakaderera zvikuru.Izvi zvinoratidza kuti tekinoroji yeUV inogona kuve mhinduro yakanaka kuchengetedza nzvimbo dzeveruzhinji. "
Mwaranzi yeUltraviolet inoburitswa nezuva, uye marudzi mazhinji anokuvadza kuzvinhu zvipenyu pamwe chete netupukanana twakadai semavhairasi.Chiedza ichi chinogona kutorwa nejenome rechinhu chipenyu, chichisunga mapfundo mukati machiri uye kuchitadzisa kuberekana.Zvisinei, aya mafungu anokuvadza anobva kuZuva anosefa neozone layer asati asvika pamusoro pePasi.
Zvimwe zvigadzirwa zvakajairika, semarambi efluorescent, zvinoshandisa ergonomic UV mwaranzi, asi zvine mukati memukati we phosphorus chena inovadzivirira kubva kune UV mwaranzi.
"Patinobvisa kupfeka, tinogona kuburitsa mafungu anogona kukuvadza ganda redu nemeso, asi anogona kuuraya hutachiona," akadaro Linden.
Zvipatara zvave kutoshandisa tekinoroji yeUV kuuraya hutachiona munzvimbo dzisina vanhu uye kushandisa marobhoti kushandisa mwenje weUV pakati pemakamuri ekuvhiya nemakamuri evarwere.
Mazhinji magajeti ari pamusika nhasi anogona kushandisa UV mwenje kuchenesa zvese kubva kunharembozha kusvika kumabhodhoro emvura.Asi iyo FDA neEPA vachiri kugadzira mapuroteni ekuchengetedza.Linden anoyambira pamusoro pekushandisa chero midziyo yemunhu kana "yekudzivirira" inofumura vanhu kuchiedza che ultraviolet.
Vati zvitsva zvawanikwa zvakasiyana nekuti zvinomiririra nzvimbo yepakati pakati pechiedza cheultraviolet, icho chakachengeteka kuvanhu uye chinokuvadza kuhutachiona, kunyanya hutachiona hunokonzera COVID-19.
Muchidzidzo ichi, Linden nechikwata chake vakafananidza kureba kwakasiyana kwechiedza cheUV vachishandisa nzira dzakamira dzakagadzirwa muindasitiri yeUV.
"Tinofunga ngatiuye pamwe chete titaure zvakajeka nezvehuwandu hwekuratidzwa kweUV kuuraya SARS-CoV-2," Linden akadaro."Tinoda kuve nechokwadi chekuti kana ukashandisa UV mwenje kurwisa chirwere ichi, uchabudirira".Dosage kuchengetedza hutano hwevanhu uye ganda revanhu uye kuuraya utachiona uhu. "
Mikana yekuita basa rakadai haiwanike sezvo kushanda neSARS-CoV-2 kunoda kuomesesa kuchengetedzwa kwemazinga.Saka Linden naBen Ma, mumwe aimbova chiremba muboka raLinden, vakabatana nachiremba wehutachiona Charles Gerba weYunivhesiti yeArizona murabhoritari ine rezinesi rekudzidza hutachiona uye zvakasiyana-siyana.
Vatsvagiri vakawana kuti nepo mavhairasi achiwanzo tarisa kune ultraviolet mwenje, imwe kure-ultraviolet wavelength (222 nanometers) inonyanya kushanda.Iyi wavelength inogadzirwa nekrypton chloride excimer marambi, ayo anofambiswa nemamorekuru anofamba pakati penzvimbo dzakasiyana dzesimba uye ane simba rakanyanya.Saka nekudaro, inokwanisa kukonzera kukuvadza kwakawanda kumapuroteni ehutachiona uye nucleic acids kupfuura mamwe maUV-C zvishandiso uye yakavharika nekunze kweganda remunhu nemeso, zvichireva kuti haina zvinokuvadza hutano.inouraya utachiona.
UV maranzi ehurefu hwakasiyana (akayerwa pano mumananometers) anogona kupinda mukati mezvikamu zvakasiyana zveganda.Iyo yakadzika mawavelengths aya inopinda mukati meganda, iyo inowedzera kukuvadza kwavanoita.(Mufananidzo: "Kure UV: Yazvino Nyika Yeruzivo" yakaburitswa neInternational Ultraviolet Radiation Association muna 2021)
Kubva pakutanga kwezana remakore rechi20, marudzi akasiyana-siyana emwaranzi yeUV ave achishandiswa zvakanyanya kuuraya utachiona hwemvura, mhepo, uye nzvimbo.Kare kuma1940, yakashandiswa kuderedza kupararira kwechirwere cherurindi muzvipatara nemudzimba dzekudzidzira nekuvheneka sirin’i kuti kuuraya utachiona hwemhepo yaitenderera mukamuri.Nhasi inoshandiswa kwete muzvipatara chete, asiwo mune zvimwe zvimbuzi zvevanhu vose uye mundege kana pasina munhu aripo.
Mune bepa jena rakabudiswa munguva pfupi yapfuura neInternational Ultraviolet Society, Far-UV Radiation: Current State of Knowledge (pamwe chete netsvagurudzo itsva), Linden nevamwe vanyori vanopokana kuti iyi yakachengeteka kure-UV wavelength inogona kushandiswa pamwe nekuvandudzwa kwemhepo, kupfeka. masks uye vaccination matanho akakosha ekudzikamisa mhedzisiro yeazvino uye yeramangwana denda.
Linden Fungidzira masisitimu anogona kuvhurwa nekuvharwa munzvimbo dzakavharwa kuti agare akachena mhepo nenzvimbo, kana kugadzira zvipingamupinyi zvisingaonekwe pakati pevadzidzisi nevadzidzi, vashanyi nevashandi vekugadzirisa, uye vanhu vari munzvimbo dzisingagone kuchengetedzwa.
UV disinfection inogona kutokwikwidza zvakanaka mhedzisiro yekuvandudza mhepo yemukati, sezvo ichigona kupa dziviriro yakafanana nekuwedzera huwandu hwekuchinja kwemhepo paawa mukamuri.Kuisa mwenje weUV zvakare kunodhura zvakanyanya pane kukwidziridza HVAC yako yese system.
“Pane mukana pano wekuchengetedza mari nesimba tichichengetedza hutano hweveruzhinji.Zvinonakidza chaizvo,” akadaro Linden.
