Ingabe Ukukhanya Kwe-UVC Kuyasebenza Kumagciwane Namagciwane?

Amagciwane kanye nama-virus ama-microorganisms amancane angabangela izifo ezihlukahlukene kanye

izimo. Ukuvimbela ukudluliswa kwezifo nezifo ezinjalo, lezi zinambuzane ezincane kufanele zisuswe ebusweni nasemoyeni. Ukusebenzisa imisebe ye-ultraviolet (UV) kungenye yezindlela eziphumelelayo zokufeza lokhu. Isibani se-UVC kukhonjiswe ukuthi kuyindlela ephumelela kakhulu yokukhanya kwe-UV yokubhubhisa amagciwane namagciwane. Lesi sihloko sizochaza ngokuningiliziwe ukuthi iyini imisebe ye-ultraviolet C (UVC), ukuthi isebenza kanjani, nokuthi iphumelela kangakanani ekubulaleni amagciwane namagciwane.

Ukukhanya kwe-UVC kunobude obuphakathi kuka-200 no-280 nanometers (nm). Inobude begagasi obufushane kunokukhanya okubonakalayo, kanye nemisebe ye-UVA ne-UVB evela elangeni esichayeka kuyo.Yaziwa nangokuthi yi-UV ebulalayo ngoba ikwazi ukuqeda i-DNA yezilwanyana ezincane ezifana nama-virus nama-bacteria.

Ngabe ukukhanya kwe-UVC kusebenza kanjani?

Isebenza ngemisebe ye-UVC ngokubangela ukulimala kwe-DNA kumagciwane anjengamabhaktheriya namagciwane. Enye yama-nucleotide amane ahlanganisa i-DNA, i-thymine, yakha izibopho eziqinile nama-molecule e-thymine aseduze lapho evezwe emisebeni ye-UVC. Lokhu kubangela ukwakheka kwe-thymine dimer, ehlanekezela isakhiwo se-DNA helix futhi ivimbele ukuphindaphinda kwe-DNA. I-microorganism ayikwazi ukubekezelela futhi ikhiqize ngaphandle kwekhono lokuphindaphinda.

Imisebe ye-UVC kufanele ibe nobude obufanele kanye namandla ukuze isebenze kahle. Isibani se-UVC  ukuqina kukalwa ngama-microwatts ngesentimitha lesikwele (W/cm2). Ukuqina kuyadingeka ukuze kuqedwe amagciwane kanye namagciwane kuncike ohlotsheni lwe-microorganism, ibanga phakathi komthombo wokukhanya kanye ne-microorganism, kanye nesikhathi sokuchayeka.

I-UVC Radiation kanye nama-bacteria

Ukukhanya kwe-UVC kuboniswe ukuthi kusebenza ngempumelelo ngokumelene nezinhlobonhlobo zezinhlobo zamagciwane. Kolunye ucwaningo, Isibani se-UVC yehlise inani lamagciwane e-Staphylococcus aureus endaweni ngo-99.9% ngemva nje kwamasekhondi angu-5 okuchayeka ku-0.32 W/cm2 wokukhanya kwe-UVC. Umzuzu owodwa wokuchayeka ekukhanyeni kwe-UVC okunamandla angu-1.8 W/cm2 bewanele ukuqeda u-99.9% wamagciwane e-Pseudomonas aeruginosa, ngokolunye ucwaningo.

Isibani se-UVC kuye kwaboniswa nokuthi kubhubhisa amagciwane amelana nemithi eminingi. Kolunye ucwaningo, imizuzwana engu-10 yokuchayeka ekukhanyeni kwe-UVC ngesilinganiso esingu-0.2 W/cm2 yehlise inani lamagciwane e-Acinetobacter baumannii angazweli emithini eminingi endaweni ngo-99.9%. Imizuzwana emi-5 yokuchayeka ku-0.5 W/cm2  Isibani se-UVC t sehlise inani lebhaktheriya elingazweli emithini eminingi i-Klebsiella pneumoniae endaweni ngo-99.9%, ngokocwaningo oluhlukile.

I-UVC Radiation kanye namaVirus

Ukukhanya kwe-UVC kutholakala kusebenza ngempumelelo ngokumelene nezinhlobonhlobo zamagciwane. Emaminithini angu-15, Isibani se-UVC  ngokuqina okungu-0.1 W/cm2 kwehlise ukusuleleka kwegciwane lomkhuhlane A ngo-99.99%, ngokocwaningo olulodwa. Kolunye ucwaningo, imizuzu eyi-15 yokuchayeka ku Isibani se-UVC ngokuqina okungu-0.5 W/cm2 kwehlise ukutheleleka kwe-coronavirus yomuntu OC43 ngo-99.9%.

Kuphinde kukhonjiswe ukuthi iyasebenza ekulweni negciwane le-SARS-CoV-2 elidala i-COVID-19 ngokusebenzisa a ngi di isifo . Emasekhondini angama-25, Isibani se-UVC  ngokuqina okungu-0.1 W/cm2 kwehlise ukusuleleka kwegciwane le-SARS-CoV-2 ngo-99.9%, ngokocwaningo olulodwa. Kolunye ucwaningo, ukuchayeka ku Isibani se-UVC ngomfutho ongu-0.05 W/cm2 kwehlise ukusuleleka kwegciwane le-SARS-CoV-2 ngo-99.9% ngomzuzu owodwa nje.

Kubalulekile ukuqaphela ukuthi ukusebenza kahle kwe   ekubhubhiseni amagciwane kuncike ezintweni eziningi eziguquguqukayo, okuhlanganisa uhlobo lwegciwane, amandla okukhanya, kanye nesikhathi sokuchayeka. Kodwa-ke, ucwaningo selukhombisile ukuthi ukukhanya kwe-UVC kungaba ithuluzi eliwusizo lokuvikela ukusabalala kwamagciwane anjengomkhuhlane, ama-coronavirus abantu, kanye ne-SARS-CoV-2.

Ukukhawulelwa kokukhanya kwe-UVC

Ukukhanya kwe-UVC kuboniswe ukuthi kusebenza ngempumelelo ekubulaleni amagciwane namagciwane, kodwa ukusetshenziswa kwakho kulinganiselwe.

●  Okokuqala, ama-microorganisms kuphela achayeka kuwo ngokuqondile angabulawa kuhlanganise ne- Ukubulawa kwamanzi kwe-UV . Ngakho-ke, izindawo ezingaphezulu nezinto ezingaxhumene ngqo nemisebe ye-UVC zisengagcina amagciwane namagciwane.

●  Okwesibili, ukuchayeka kuyo ngokuqondile isikhathi eside kungaba yingozi kubantu.Ukuchayeka ngokweqile kungaholela esikhumbeni, ekulimaleni kwamehlo, nezinye izinkinga zempilo. Ngakho-ke, kubalulekile ukuthobela izinkombandlela zokuphepha kokukhanya kwe-UVC futhi uqinisekise ukuthi abantu abavezwa ngokuqondile ekukhanyeni.

●  Okwesithathu, ikwazi ukucekela phansi amabhaktheriya namagciwane kuphela uma isetshenziswa ngamandla nobude besikhathi esifanele. Ingase ingasebenzi kahle ekuqedeni ama-microorganisms uma ukuqina noma ubude besikhathi sokuchayeka bungenele.

●  Okokugcina, imisebe ye-UVC ingase ingasebenzi ngokumelene nawo wonke amagciwane namagciwane. Amanye ama-microorganisms namagciwane angase amelane kakhulu nokukhanya kwe-UVC kunamanye.

Akuzona Zonke Izibani ze-UV ezifanayo!

Akuyona yonke imisebe ye-UV esebenza ngokulinganayo ekubhubhiseni amagciwane namagciwane. Kunezinhlobonhlobo zezinhlobonhlobo zokukhanya kwe-UV, ngayinye enamaza ahlukene kanye nezakhiwo. Ukuze uqonde umehluko phakathi kwezinhlobonhlobo zokukhanya kwe-UV, kuyadingeka ukuhlola i-ultraviolet spectrum.

I-UV-A ne-UV-B

I-UV-A kanye ne-UV-B yizinhlobo ezaziwa kakhulu zokukhanya kwe-ultraviolet, futhi ziyimisebe yelanga efinyelela ebusweni bomhlaba. Nokho, ezinye izinhlobo zokukhanya kwe-UV zivame ukusetshenziswa emikhiqizweni ebulala amagciwane emoyeni.

UV-C

I-UV-C, eyaziwa nangokuthi i-Germicidal UV, iqukethe ubude begagasi phakathi kuka-200 no-280 nanometers. Lolu uhlobo oluvamile lwe-UV ebulala amagciwane ososayensi abaye balusebenzisa isikhathi esingaphezu kwekhulu leminyaka ukuze babulale amagciwane emanzini, umoya, nendawo. I-UV-C ibhubhisa ngempumelelo futhi yenze zonke izinhlobo zezinto ezincane zingasebenzi, okuhlanganisa amagciwane, amagciwane, isikhunta, nesikhunta.

Okude-UVC

I-Far-UVC isethi engaphansi ye-UV-C, ehlanganisa amaza amaza aphakathi kuka-207 no-222 nanometers. I-Far-UVC ihlukile ngoba kukholakala ukuthi ayinabungozi ekuchayekeni kwabantu. Lo mkhakha othile wokukhanya unomkhawulokudonsa omncane kakhulu owuvimbela ukuthi ungangeni ngale kongqimba olungaphandle lwe-epidermis yethu, kodwa usengabulala amagciwane namagciwane. Kule minyaka eyishumi edlule, ososayensi baqale ukugxila ku-UVC ekude, ngakho ucwaningo lwemiphumela emibi engaba khona lulinganiselwe kune-UV-C.

Eduze kwe-UV

I-UV eseduze ikakhulukazi iqukethe amaza amaza e-UV-A, asenazo izici zokubulala amagciwane kodwa engakwazi ukucekela phansi amagciwane afana ne-UV-C. Ezikhungweni zezokwelapha nasezikhungweni zokunakekela abantu abadala, eduze nokukhanya kwe-ultraviolet kungasiza ekunciphiseni amazinga okutheleleka ngamagciwane. Lawa maza obude aseduze kakhulu nobubanzi bokukhanya okubonakalayo futhi kucatshangwa ukuthi aphephile kubantu.
