IsOhwe
IsOhwe,noma (uMoya-mpilo)siyinhlwa yevangaenophawuOnenani lobuChweisi-8. Siyilungu leqembu le-chalcogenecansini lezinhlwa,okusenza into engenkimbi enanela kakhulu, futhi iyisithuhli(oxidizer)esikulungele ukwakhaizintuhlanezinhlwa eziningi kanye neminyeimixube.IsOhwe siyinhlwa eyinala kakhulukuNomkhubulwane,futhi ilandelaihwanzinehwelanganjengenhlwa yesithathu eyinala ngokwengeziwekumkhathilibe.Ezingeni lokushisa nokucinana okujwayelekile, amachwe amabili enhlwa enza isibhonqi ukuze akheisOhwembili,okuluhowo olungenambala nolungenaphunga lobuchwembili.UHowolwesOhwe yobuchwembili kuyimanje lwakha amaphesenti angama-20.95%woMoyambulungakaNomkhubulwane, yize lokhu kushintshe kakhulu emva kwesikhathi eside. IsOhwe sakha cishe isigamu segobohla lukaNomkhubulwane esimweni seNtuhla.
Zonkeizitshalo,izilwane,nokhuntaziyizinto ezidinga isOhwe ukuze kube nokuphefumula emangqamuzaneni, okuyinqubo egqoba isidlakathi lapho kulumbana isOhwe nemizwayi athathwe ekudleni futhi kukhiqiza umCalahle ontuhlambili njengemfucumfucu. Ezilwaneni ezinomhlandla ukuphefumula kusho ukufaka isOhwe emaphashini lapho kunanana khona uhowo, umCalahle ontuhlambili uhlakazeka uphume egazini, futhi isOhwe lungena luhlakazeke egazini. Uhlelo lomjikelezo womzimba luthutha isOhwe emangqamuzaneni, lapho ukuphefumula kwamangqamuzana okwenzeka khona.
Izigaba ezinkulu eziningi zamizwayi yemveloziseziphilinieziphilayo eziqukethe amachwe esOhwe, afananezakhamzimba,izimunyundeni,izifukuthisi namanoni, njengoba kunjalo nangezakhi ezinkulu zemixube engeyona eyemvelo yamagobongo ezilwane, amazinyo namathambo. Iningi lesisindo seziphili liyisigcoyisamanzi,okuyisakhi esiyinhloko sezinhlobo zokuphila. IsOhwe sihlunyeleliswa ngokuqhubekayo kumoyambulunga womhlaba ngenqubo yomdibakhanyo, esebenzisa isidlakathi sokukhanya kwelanga ukukhiqiza isOhwe kusuka emanzini nakumcalahle ontuhlambili. IsOhwe senana ngokwevanga ukuba singaba yinhlwa ekhululekile emoyeni ngaphandle kokuhlunyeleliswa ngokuqhubekayo yisenzo somdibakhanyo seziphili. Olunye uhlobo lwesOhwe, intshongohwe (ozone (O 3), lumunyunga ngamandlaimiyonzi kazukhwithiye-UVB futhi ubuhalalazi bentshongohwe buwusizo ekuvikeleni impilombulunga emiyonzini kazukhwithi. Kodwa, intshongohwe ekhona ebusweni bomhlaba ingumkhiqizo we-smogfuthi kanjalo isingcolisi moya.
