    Ibisobanuro

     

    Ubushakashatsi bwatubanjirije bwerekanye ko gushungura fibre ya fibre hamwe namavuta yicyayi ikora yibinyabuzima (TTO) byongera imbaraga zo gukusanya umubiri muburyo bwo gushyushya bisanzwe, guhumeka, no guhumeka neza (HVAC), kandi bigatanga uburyo bwihuse kandi bwihuse bwo gukora udukoko twa bagiteri na fungal twafashwe muyunguruzi. Intego nyamukuru yubu bushakashatsi kwari ugukora iperereza ku bikorwa bya virusi itera indwara zanduza ebyiri, ni ukuvuga TTO n’amavuta ya eucalyptus (EUO), kurwanya virusi y’ibicurane yafashwe hejuru y’ayunguruzo. Byagaragaye ko amavuta yombi yapimwe afite imiti ikomeye ya virusi iyo ikoreshejwe nk'ibikoresho bifata fibre, ishobora gukora mikorobe zafashwe mu minota 5-10 yo guhura hejuru ya fibre. Igikorwa cyo kurwanya virusi ya TTO nacyo cyatsinzwe muburyo bwa aerosol mu kuvanga uduce duto twa virusi yo mu kirere hamwe n’ibitonyanga bya peteroli mu cyumba kizunguruka cya aerosol. Ibisubizo bisa nkibyiringiro cyane kugirango habeho iterambere ryimikorere ya virusi na tekinoroji yo gukoresha ikirere cyiza.

     

    Intangiriro

    Kubera ingaruka zitari nke ku buzima bw’abantu n’inyamaswa, aerosole y’ibinyabuzima igenda iba ikintu cy’ingenzi mu bushakashatsi bwakozwe ku isi hose. Kurandura mikorobe ya mikorobe mu kirere kidukikije hamwe no kudakurikira kwayo kwaba bumwe mu buryo bwiza bwo kugabanya ingaruka ziterwa no guhura n’ibice byo mu kirere cyangwa uduce twongeye guhindurwa mu kirere. Kubera ko kuyungurura bikomeje kuba uburyo bwiza bwo kuvanaho ikirere cyo mu kirere, gikunze gukoreshwa mu kweza umwuka mu bice bya mikorobe byonyine, cyangwa bigahuzwa n’uburyo bwiyongera hamwe n’ikoranabuhanga ryongerera imbaraga imikorere hamwe no guhindura bike muyungurura hydrodynamic. Bene ubwo buryo bwo kongera akayunguruzo harimo gukoresha ion unipolar (Huang et al. 2008), kwishyuza amashanyarazi ya media ya filteri (Raynor na Chae 2004), gutwika fibre hamwe n'amazi (Agranovski na Braddock 1998; Boskovic et al. 2007), nibindi. .

     

    Urebye ko aerosole yakusanyije mikorobe ikomeza kuba hejuru ya filteri, bimwe bishoboka ko byakurikiraho hanyuma bakongera bagasubira mu kirere bitwara gaze ntibishobora kwirengagizwa. Ibice byongeye guhindurwa mu kirere bishobora kuba bizima bitera ingaruka zikomeye kubaturage n'ibidukikije. Iki kibazo gishobora gukemurwa hiyongereyeho imiti yica udukoko mu gutwara gaze cyangwa gukora uburyo bumwe na bumwe bwo kudakora ku buryo butaziguye hejuru ya filteri, bigatuma uduce duto twa mikorobe tudakora mugihe gishobora kongera kuba aerosolisation.

     

    Hariho uburyo bumwe bwikoranabuhanga buboneka kuri mikorobe. Harimo kwangirika kwa fotokatike ya mikorobe hejuru ya titanium oxyde irasa na ultraviolet (UV; Vohra et al. 2006; Grinshpun et al. 2007), infragre (IR) ishingiye kumirasire yumuriro (Damit et al. 2011), ikoresheje imiti yatewe mu buryo butaziguye; mu bwikorezi bwo mu kirere cyangwa bigashyirwa hejuru ya filteri (Pyankov et al. 2008; Huang et al. 2010), n'abandi. Mu moko atandukanye yanduza, amavuta amwe amwe asa nayizere kubera imiterere mike cyangwa idafite ubumara, cyane cyane muburyo bworoshye (Carson et al. 2006). Mu myaka icumi ishize, hagenzuwe amavuta atandukanye yingenzi ava mu bimera kugira ngo asuzume ibikorwa bya mikorobe (Reichling et al. 2009).

     

    Ikoreshwa ry'amavuta, nk'amavuta y'ibiti by'icyayi (TTO) n'amavuta ya eucalyptus (EUO), kuko imiti yica udukoko twagaragaye mu bushakashatsi bwa vitro bwerekeranye na antibacterial (Wilkinson na Cavanagh 2005; Carson n'abandi 2006; Salari n'abandi. 2006) Hayley na Palombo 2009), antifungal (Hammer et al. 2000; Oliva et 2003), n'ibikorwa bya virusi (Schnitzler et al. 2001; Cermelli et al. 2008; Garozzo et al. 2011). Byongeye kandi, herekanywe ko amavuta yingenzi ari imvange itandukanye, hamwe nibice byinshi kugirango ibice bitandukanye bitandukane, bitewe nuburyo imikurire ihingwa (Kawakami et 1990; Moudachirou et al. 1999). Ibikorwa birwanya mikorobe ya TTO biterwa ahanini na terpinen-4-ol (35-45%) na 1.8-cineole (1-6%); icyakora, ibindi bice nka a-terpineol, terpinolene, na a- na c-terpinene nabyo birahari kandi birashobora kugira uruhare mu kwanduza mikorobe (Gicurasi et 2000). EUO yo mu bwoko butandukanye bwa Eucalyptus irimo 1,8-cineole, a-pinene, na a-terpineol nk'ibintu rusange bisanzwe (Jemâa et al. 2012). Urwego rwa farumasi rwa EUO rusanzwe rukungahaye kuri 70% ya 1.8-cineole.

     

    Vuba aha, twasabye ikoranabuhanga rishingiye ku gutwika fibrous filtri na TTO, tunatanga raporo y'ibyavuye mu bushakashatsi bwakozwe ku bijyanye no kwanduza bagiteri (Pyankov et al. 2008) na spore spore (Huang et al. 2010). Muri ubu bushakashatsi, TTO yakoreshejwe nka byombi, gushungura neza byongera itangazamakuru hamwe na disinfectant kuri aerosole ya bagiteri na fungal yafashwe hejuru ya filteri. Urebye ko muri iki gihe dushishikajwe n’ubushakashatsi bujyanye n’ibicurane, ubu bushakashatsi ni ugukomeza mu buryo bwumvikana iperereza ryacu ryibanze twibanze ku gusuzuma ibikorwa bya virusi y’amavuta y’ibanze (TTO na EUO) ku kudakora virusi y’ibicurane byo mu kirere.
