Phakathi kwe-9-to-5 yedesika yomsebenzi wakho, iyure okanye uchitha ixesha lokumpompa intsimbi kwindawo yokuzivocavoca, kunye nazo zonke ii-Netflix zakho zokuzinkcinkca zasebusuku, akumangalisi ukuba mhlawumbi uchitha malunga neepesenti ezingama-90 zexesha lakho ngaphakathi. Inqaku kuqhambuko lwe-coronavirus kunye nemiyalelo elandelayo yokuhlala ekhaya, kunye nexesha lokugqibela ukuphuma kwilizwe langaphandle-nokuba ibikukuhamba nje ukuya kwivenkile yokutya-inokuba yayiziintsuku ezintathu ezidlulileyo.

Ngalo lonke elo xesha longezelelekileyo obulichitha kwindawo yakho yokuhlala ethobekileyo, usenokuba uqokelele inkuthazo yokuyiguqula ibe yindawo ephilileyo, uqale ngokuthenga izityalo zokucoca umoya. Emva kwayo yonke loo nto, uxinzelelo lwezinto ezingcolisayo zinokuphindaphindeka kabini okanye ezintlanu ngaphakathi endlwini kunangaphandle, ngenxa yento yokucoca, ipeyinti, kunye nezinto zokwakha ezisetyenzisiweyo kwisakhiwo sakho, ngokwe-Arhente yoKhuselo lweNdalo. Kwaye ezi zinto zixubeneyo (VOCs, aka the gases ezikhutshwe kwezi mveliso zasekhaya nangaphezulu) zinokukhokelela kwiziphumo zempilo ezinobungozi, kubandakanya iliso, impumlo, kunye nomqala; intloko ebuhlungu kunye isicaphucaphu; kunye nokulimala kwesibindi, phakathi kwabanye, ngokwe-EPA.

Kodwa ngaba le palm pallor ihleli kwifestile yakho okanye isityalo senyoka kwitafile yokugqibela ecaleni kwebhedi yakho yenza nantoni na ukunceda imeko?

Okulusizi kukuba, nokuba ikhaya lakho likhangeleka ngathi lelikwi-Instagram's Discover page, ayizukufumana umoya ococekileyo njenge-oksijini ngqo ngaphandle kwetanki. UMichael Dixon, umlawuli weZiko Elilawulayo Lokuphanda Ngeenkqubo Zokulawula Indalo kwiYunivesithi yaseGuelph kumazantsi eOntario, eKhanada uthi: “Eyona nto ixhaphakileyo yeyokuba izityalo ziyawucoca umoya. "Izindlu zidlala indima encinci kakhulu kumgangatho womoya abakuwo, kwaye iimpembelelo zawo zikhulu kakhulu kuba umgangatho wabo wobuhle ukukwenza uzive ulungile."

Ngapha koko, uphononongo lowama-2019 lwezifundo ezili-12 ezipapashiweyo kwizityalo ezinamanzi kwi-VOCs ezihamba ngomoya zifumene kanye loo nto. Ipapashwe kwi Ijenali yeSayensi yokuBonisa kunye ne-Epidemiology yendalo esingqongileyo, Uphononongo lufumene ukuba ukutshintshiselana komoya, mhlawumbi ngokuvula iifestile okanye ukusebenzisa iinkqubo zokungenisa umoya, kunciphisa ukugxininiswa kwee-VOC ngokukhawuleza kunokuba izityalo zikwazi ukuzikhupha emoyeni. Oko kuthetha ukuba uyakufuna naphi na ukusuka kwi-100 ukuya kwi-1 000 yezityalo kwimitha yesikwere (malunga neenyawo ezili-10 zesikwere) sendawo yomgangatho ukuze ususe ii-VOC ngokukuko njengokuqhekeka kuvuleke igumbi lokuhlala. Ukuba ufuna ngokwenene ukuhlala endlwini yakho, oko akunakwenzeka ncam.

Emva kwentsomi

Ke kwenzeka njani ukuba imbono ephosakeleyo yokuba izityalo ezimbalwa ezifakwe embizeni zingalijika ikhaya lakho libe yindawo ye-oasis enomoya omtsha ifumane ukutsaleka? Yonke le nto yaqala emva phayaa-1980s kunye nososayensi we-NASA uBill Wolverton, utshilo uDixon, obhalise isifundo ngo-2011 malunga nomxholo opapashwe kwi I-Biotechnology eBanzi. Ukuze ufumanise ukuba zeziphi izityalo ezenze owona msebenzi ulungileyo wokuhluza izinto ezingcolisa indalo, uWolverton wavavanya ishumi elinesibini lezityalo zendlu eziqhelekileyo-ezifana ne-gerbera daisy kunye ne-bamboo palm-ekukwazini kwazo ukususa i-toxins yasekhaya kwi-30-intshi kunye ne-30-intshi yegumbi elitywiniweyo. , ngokutsho kweNASA. Emva kweeyure ezingama-24, uWolverton wafumanisa ukuba izityalo zisuse ngempumelelo iipesenti ezili-10 ukuya kwezingama-90 zezinto ezingcolisayo, eziquka i-formaldehyde, i-benzene, ne-trichlorethylene, emoyeni. (Eyeleleneyo: Umgangatho woMoya ukuchaphazela ukusebenza kwakho [kunye nempilo yakho] ngaphezulu kunokuba ucinga)

Ingxaki ngophando: I-Wolverton yabeka izityalo kwiidosi zokungcolisa i-10 ukuya kwi-100 ngokuphindwe kabini kunokuba uqhele ukuzifumana emoyeni wangaphakathi okumgangatho ophantsi, kwaye zabekwa kumagumbi amancinci kakhulu, utsho u-Dixon. Ukuze ufumane iziphumo ezifanayo, u-Wolverton ubale ukuba kuya kufuneka ube nezityalo zesigcawu ezimalunga nama-70 kwikhaya langoku, eliwonga amandla li-1800-square-foot. Uguqulo: Iziphumo azinakusebenza kuseto lwehlabathi lokwenyani njenge-condo yakho ephakathi.

Kwezinye iimeko, isimo sakho sikaMama weSityalo sinokwenza umgangatho womoya wakho ube mandundu. Umhlaba wokubumba unokuba ngumthombo wongcoliseko emoyeni, ngakumbi ukuba ungaphezulu kwamanzi okanye usebenzisa isichumiso esininzi, utshilo uDixon. Umhlaba ofumileyo kakhulu unokukhuthaza ukukhula kwee-microorganisms ezinokubangela ukungabikho komzimba kwabanye abantu, kwaye iityuwa ezivela ekusebenziseni isichumiso ngokweqile zingakhuphuka emoyeni, wongezelela.

Ngaba izityalo zokucoca umoya zinayo nayiphi na impembelelo?

Cinga emva kwiklasi yebhayoloji yakho yamabanga aphakamileyo, kwaye uya kuba nokuqonda okuqinisekileyo malunga nokuba zeziphi izityalo zakho zokucoca umoya ezinokukwenza ngenene *: Thatha ikharbhon diokside kwaye ukhuphe ioksijini ngefotosinthesisi, utshilo uDixon. Izityalo zasendlwini ngokwemvelo zineendlela zemetabolism (ukusabela kweekhemikhali kwiiseli ezakha kwaye ziqhekeza iimolekyuli zeenkqubo zeselula) ukuba zisebenzise i-carbon dioxide, kodwa azinayo ngokwaneleyo ezo zithatha ukungcola okuyingozi okufumaneka emoyeni okumgangatho ophantsi. yenza impembelelo ebalulekileyo, uyachaza. (Ubuncinci ukugcina isitiya sangaphakathi kuya kukunika imveliso entsha nawe.)

Nangona kunjalo, iiplanti zasendlini azikho ukucoca umoya, oomatshini be-CO2-busting. Kuba uninzi lwezithuba zangaphakathi zinamazinga okukhanya asezantsi, izityalo zihlala zisebenza kwinqanaba lokuphefumla (ukuthatha ikharbhon diokside kunye nokukhupha ioksijini kunye ne-CO2) ilingana naleyo yefotosinthesisi, utshilo uDixon. Ngeli xesha, isityalo sithatha umlinganiselo ofanayo we-CO2 ukusuka emoyeni njengoko uvelisa. Ngenxa yoko, "ithemba lokuba izityalo ezibhotelweyo zibe ngumdlali ophambili ekuphuculeni umgangatho womoya wendawo yangaphakathi lincinci kakhulu," ucacisa.

Kodwa iimpawu zokucoca umoya zezinye izityalo aziyonyani iyonke. Kwezinye kakhulu Iimeko ezithile, ii-VOCs zinokusebenza njengokutya kuluntu lwentsholongwane (re: bacteria kunye nokungunda) kwindawo yeengcambu zesityalo, yenze “i-biofilter” eyehlisa ungcoliseko emoyeni. Nangona kunjalo, ayisiyonto onokuyiphumeza ngesityalo sakho se-pothos, utsho uDixon. Ukuqala, ezi biofilters zezityalo ziyilelwe ukugquma iindonga zonke kunye nobude obuthathu ukuya kwamane amabali aphezulu.

Ezi ndonga zinkulu zizaliswe zizityalo zinamaphiko kwaye zinamanzi ajikeleza kuzo ukwenza indawo efanelekileyo yokuba iintsholongwane zihlale ngokonwaba, ezaziwa ngokuba yi-biofilm. Abalandeli kwinkqubo badonsa umoya wegumbi emhlabeni, kwaye naziphi na ii-VOCs zinyibilika kwi-biofilm, utshilo uDixon. Xa izityalo zenza i-photosynthesis kwaye zivuza i-carbohydrate ukuya ezingcanjini, iindawo ezincinci ezihlala kwi-biofilm ziyitshisa-kunye nazo naziphi na izinto ezingcolileyo ezazifunxwa kuyo, uyachaza. UDixon uthi: “Izinto eziphilayo eziguquguqukayo esizinxulumanisa nomoya ongekho mgangathweni wangaphakathi luhlobo oluthile lwesnack [yeentsholongwane],” utshilo uDixon. "[Ii-VOCs] azikho kwindawo ephezulu ngokwaneleyo yokugcina intsholongwane-ke izityalo zikwenza oko [ngephotosynthesis]."

Ukuzama ukwenza i-biofilter yakho kwisityalo esinembiza “kunzima kakhulu,” ngenxa yaloo manqanaba okukhanya aphantsi afumaneka emakhaya, utshilo uDixon. Ukungathethi, zinzima kakhulu ukuzigcina kwaye azifumaneki kusetyenziso lwasekhaya okwangoku. Kodwa awuyo-SOL ngokupheleleyo ukuba ufuna ukucoca umoya wakho wangaphakathi: "Ngokoqobo, vula nje ifestile, eya kuphucula ukutshintshiselana kwegesi ngaphandle," utsho. (Kwaye ukuba ikhaya lakho liyindlela egudileyo, vula enye yezi zinto zichazwe apha ngasentla.)

Kwaye ngelixa isityalo sakho sokucoca umoya singenakho ukwenza umsebenzi owawunethemba lokuba ubuncinci, ubuncinci ukuba ujikeleze uhlaza kunokukunceda ukuba uvelise ngakumbi kwaye unciphise amanqanaba oxinzelelo, ngokophando oluvela kwiYunivesithi yaseWashington State. Kwaye, ukubakhathalela kulungile #ukukhula kwabantu abadala ngaphambi kokuba ekugqibeleni uthathe injana, akunjalo?
