Pfupiso
Ongororo yeStanford University inoratidza kuti zvitofu zvegasi nepropane zvinoburitsa benzene, iyo inokonzera kenza muboka rekutanga yakabatana neleukemia, pahuwandu hunogona kudarika utsi hwemunhu anosvuta.
Kubika kwemaminitsi makumi mana nemashanu chete kunogona kuwedzera huwandu hwebenzene mumba hunopfuura mwero wehutano, gasi richigara mumakamuri ekurara kwemaawa anopfuura masere.
Kusiyana nemidziyo yekubikira inoburitsa zvinhu zvinopisa, iyo inoburitsa huwandu hushoma, zvitofu zvegasi zvine njodzi huru pahutano kana chero chinhu chipi zvacho chikakuvadza.
Kunyange hazvo vazhinji vachifunga kuti utsi hwemafuta ekubikisa chete ndihwo hunokonzera kenza, gasi rechisikigo rinoshandiswa muzvitofu ndiro rinokonzerawo kenza. Kunze kwekuburitsa carbon dioxide uye methane inogona kukonzera kenza, zvitofu zvegasi zvinogadzira makemikari anokuvadza akadai se kabhoni monokisaidhi (CO2), iyo inodzivisa kufema kwemasero; formaldehyde (HCHO), chinokonzera kenza; nitrogen dayoksaidi (NO2), chirwere chinotsamwisa mweya chinokonzerwa neasthma; uye benzene (C6H6).
Kuti izvi zvisaitike, nyanzvi dzinokurudzira matanho matatu: kuwedzera kufefetera nekushandisa mafeni uye mahwindo akavhurika kana kufefetera mumba, kuchengetedza zvitofu zvisina mafuta, uye kushandisa midziyo yemagetsi yakaita sema air fryer kuderedza kupisa kwegasi.

Zvitofu zvegasi zvinoburitsa benzene yakawanda sei?
Zvitofu zvegasi zvine simba guru uye maovheni (akaiswa pa350 °F) zvinoburitsa avhareji ye2.8 ne5.8 μg yebenzene paminiti, zvichiteerana. Kune avo vanoshandisa gasi remafuta emvura (LPG), mitengo yacho i5.5 ne6.5 μg paminiti.
Data rinoratidza kuti huwandu hwema benzene muzvitofu zvegasi mumba hunogona kudarika huwandu hunowanikwa muutsi hwemunhu. Kusiyana neizvi, mapoto ekubikisa anoburitsa benzene shoma zvakanyanya—inenge 1/25 kusvika 1/10 chete yezvitofu zvegasi—izvo zvisinganyanyi kukosha.

Kushandisa chitofu chegasi kwemaminitsi makumi mana nemashanu chete kunogona kukonzera huwandu hwebenzene yekicheni hunopfuura mwero wehutano. Mudzimba dzakavhurika kana kana masuo akasiyiwa akavhurika, benzene inotamira kumakamuri ekurara. Mukati memaawa masere ekubika, huwandu hwebenzene yemukamuri yekurara hunogona kusvika 2.8 ppbv—yakapetwa ka23 kupfuura huwandu hwebenzene isati yabikwa—uko inoenderera mberi uye ichikonzera kukuvara kusingaperi.
Tingabika sei zvakachengeteka uye zvine Benzene Concentrations muLower Indoor?
1. Fefetedza Nemhepo Zvakanaka Paunenge Uchibika Fefetedza ndiyo nzira inonyanya kushanda. Kuti benzene isapararire, vhara magonhi emukamuri yekurara wovhura mahwindo ekicheni. Kana mhepo isina kutenderera zvakanaka, shandisa feni kuti uwedzere kuyerera kwemhepo kana kuisa chinhu chose-Sisitimu Yekufefetedza ImbaMushure mekubika, chengetai feni nemahwindo zvakavhurika uye siyai mukicheni kwenguva pfupi kuti musanyanya kusviba. Cherechedzai: Magirazi ekuchengetera anoramba achikosha pakubvisa utsi hwemafuta, izvo zvinogonawo kukonzera kenza yemapapu.
2. Chenesa Chitofu Nguva Dzose Mafuta akasara pachitofu anowedzera mukana wekubuda kwebenzene. Kana kicheni yangobuda mhepo, pukuta chitofu nemidziyo yekubikira kuti uderedze kusvibiswa kwemhepo.
3. Shandisa Midziyo Yekicheni Yakasiyana Kugocha nekupisa zvakanyanya zvinogadzira benzene yakawanda. Funga nezvekuchinja kushandisa ma induction cooktops kuti ushandise nzira idzi. Neimwe nzira, shandisa ma air fryer kana ma electric rice cookers kuti uderedze kushandisa gas stoves uye kuderedza njodzi yako.
Mibvunzo Inowanzo bvunzwa
1. Benzene inobva muzvitofu zvegasi ine njodzi kupfuura utsi hwemafuta here?
Zvese zvine njodzi. Kunyange hazvo utsi hwemafuta huchibatanidzwa nekenza yemapapu, benzene ikenza yeboka rekutanga yakabatana zvakanyanya nekenza yeropa yakaita seleukemia, kunyangwe paine huwandu hushoma hwezvinhu zvinosvibisa.
2. Ko range hood ichagadzirisa dambudziko rebenzene here?
Hazvina kunyatsojeka. Magirazi ekuchengetera zvinhu anobatsira, asi anowanzo kundikana kubata zvese zvinobuda mugasi. Kuasanganisa nemahwindo akavhurika nemafeni kunoshanda zvakanyanya.
3. Benzene inongogara mukicheni chete here?
Benzene inongopinda mumakamuri ekurara nenzvimbo dzekugara, uko inogona kuramba iri muhuwandu hwakawanda kwemaawa anopfuura masere mushure mekunge chitofu chadzimwa.
4. Ndinofanira kuchinja kuenda kunzvimbo yekubikira inogadzirwa ne induction here?
Kana zvichibvira. Mapoto ekubikisa anoburitsa benzene shoma ka10 kusvika ku25 pane zvitofu zvegasi, zvichiita kuti zvive zvakachena uye zvakachengeteka panzvimbo pemhepo yemukati.
