Ozone depletion Man-made tebchaw xws li chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) thiab halons rhuav tshem ozone nyob rau saum huab cua (stratosphere). … Stratospheric ozone poob tuaj yeem ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig, suav nrog: nce kev mob qog noj ntshav ntawm daim tawv nqaij thiab kab mob cataracts
chlorofluorocarbons cuam tshuam li cas rau lub ntiaj teb txheej ozone?
Chlorofluorocarbons yuav cuam tshuam lub ntiaj teb ozone txheej thaum UV hluav taws xob tsoo CFC particle nws ua rau ib qho tshuaj chlorine iota cais tawmCov tshuaj chlorine ntawm qhov taw tes tsoo ib qho ozone particle uas muaj peb cov pa iotas. thiab siv ib qho ntawm cov pa oxygen, obliterating lub ozone atom thiab hloov mus rau oxygen.
Puas chlorofluorocarbons ua rau huab cua muaj kuab paug?
Cov pa phem kuj tuaj yeem ua rau huab cuasaum lub ntiaj teb saum npoo av. Ib qho piv txwv zoo ntawm qhov kev puas tsuaj no yog tshwm sim los ntawm chlorofluorocarbons (CFCs). CFCs tau siv ntau xyoo los ua cov dej txias hauv cov tub yees thiab ua cov tshuaj ntxuav. … Ib qho piv txwv zoo tshaj plaws ntawm kev thauj mus los ntev ntawm cov pa phem yog cov kua qaub los nag.
Puas yog chlorofluorocarbons nce hauv huab cua?
Txij li xyoo 2013, kev tso tawm txhua xyoo ntawm kev txwv chlorofluorocarbon (CFC) tau nce li ntawm 7,000 tonnes los ntawm sab hnub tuaj Suav teb, raws li kev tshawb fawb tshiab. … Qhov kev tshawb pom no tau hais txog vim tias CFCs yog qhov ua txhaum loj hauv kev depletion ntawm stratospheric ozone txheej, uas tiv thaiv peb ntawm lub hnub lub ultra-violet hluav taws xob.
Yuav ua li cas chlorofluorocarbons rhuav tshem ozone?
Gaseous CFCs tuaj yeem deplete txheej ozone thaum lawv maj mam nce mus rau hauv stratosphere, tawg los ntawm muaj zog ultraviolet hluav taws xob, tso cov chlorine atoms, thiab tom qab ntawd hnov mob nrog ozone molecules. Saib Ozone Depleting Substance.)
