Chii chiri miuyo yemiti yomumba?
Context:Zvirimwa zvemumba hazvina zvazvinoita pakusanganiswa kwemakemikari anobhururuka (VOCs) mumamiriro ezvinhu epamba: zvaizoda pakati pe10 ne1000 zvirimwa zvemumba pamamita akaenzana kuti uwane mwero wakafanana wekubviswa kweVOC sezvinoitika kubva mukutsinhana kwekunze pakati pemhepo yemukati nekunze.  Pfungwa yokuti miti yokurima ine zvainoita pakunaka kwemhepo iri mumba inobva zvikurukuru paChidzidzo cheMhepo Yakachena chakaitwa neNASA muma1980. Chidzidzo chacho chakaedza zvirimwa zviri mumakamuri akavharwa uye zvine mwero wakakwirira wemakemikari anoputika (kunyanya benzene, trichloroethylene uye formaldehyde). Yakagumisa kuti kusvikira patambanuko iyo miti yomumba inovandudza nayo kunaka kwemhepo, muitiro webasa ndiwo utachiona huri mukati mevhu rokukandira, panzvimbo pemiti imene.  Zvirimwa zvomukati zvine zvazvinoita pamwero wezvose zviri zviviri carbon monoxide uye carbon dioxide mumamiriro ezvinhu epamba, zvichideredza mwero wecarbon dioxide ne10-25% uye mwero wecarbon monoxide neinosvika 90%. Mugumisiro wacho wakaongororwa neNASA kuti ishandiswe muzvikepe zvomuchadenga.  Zvirimwa zvinoratidzawo kuwedzera uwandu uye kusiyana-siyana kwemabhakitiriya ari mudzimba, uku zvichideredza kusiyana-siyana kwefungus. Zvinowanzokonzera kuwedzera mwando, kuderedza kuchinja-chinja kwetembiricha, uye kuderedza ruzha.  Kunewo betsero zhinji dzinotaurwa dzendangariro nedzomuviri dzokuva nemiti yomumba. Ongororo yakadzokororwa yemabhuku anotaura nezvezvirwere izvi yakabudisa kuti zvidzidzo zvakaongororwa zvinoratidza kuti miti yomumba inogona kubatsira mupfungwa zvakadai sokuderedza kushushikana uye kuwedzera kutsungirira kurwadziwa. Zvisinei, zvakaratidzawo kuti nzira dzacho nemigumisiro yacho zvakanga zvakasiyana chaizvo. Naizvozvo tine kusava nechokwadi kwakasimba nezvezvinonzi zvinomera zvemukati zvinokonzera kuchinja kwepfungwa kunobatsira. Kunoratidzika kuti betsero dzinotsamira pazvinhu zvomugariro umo miti yomukati inosangana uye pazvinhu zvavanhu vanosangana nayo".
Kunewo betsero zhinji dzinotaurwa dzendangariro nedzomuviri dzokuva nemiti yomumba. Zvirimwa zvomukati zvine zvazvinoita pamwero mukuru pamwero wecarbon monoxide necarbon dioxide mumamiriro ezvinhu epamba. Zvirimwa zvinoratidzikawo sezvinowedzera uwandu uye kusiyana-siyana kwemabhakitiriya mudzimba, uku zvichideredza kusiyana-siyana kwefungus. Zvinowanzokonzera kuwedzera mwando, kuderedza kuchinja-chinja kwetembiricha, uye kuderedza ruzha. Kunewo betsero zhinji dzinotaurwa dzendangariro nedzomuviri dzokuva nemiti yomumba. Zvirimwa zvomukati zvinogona kubatsira mupfungwa zvakadai sokuderedza kushushikana uye kuwedzera kutsungirira kurwadziwa.
