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.)

Puas ubi nce nce nqi?
Qhov kev sib cav tseem ceeb tawm tsam, lossis qhov tsis zoo rau, cov nyiaj tau los thoob ntiaj teb yog qhov muaj peev xwm ua rau nws ua rau runaway inflation, uas yuav kawg nce tus nqi ntawm kev nyob . Yuav se nce nrog UBI? Rau cov uas tau nyiaj tsawg dua $ 10,000 ib xyoos hauv cov nyiaj ua haujlwm, UBI qhov kev pab cuam yuav xaus rau lawv tus nqi nruab nrab ntawm $ 12, 316 ib xyoos, raws li AEI.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau?
Ntau tus neeg ua tiav lawv txoj kev kho hniav thiab muaj cov hniav zoo nkauj, txawm li cas los xij, thaum lawv luag ntxhi lawv pom cov hniav luv luv lossis cov pos hniav ntau dhau "gummy luag". Cosmetic crown lengthening yog ib txoj hauv kev yooj yim uas tuaj yeem ua tau zoo heev ua kom lub ntsej muag luag ntxhi ntawm cov neeg mob no .
Puas yog cov atoms ntawm oxygen tsim nyob rau hauv lub stratosphere?
Cov neeg ntawm cov pa yog tsim nyob rau hauv stratosphere thaum oxygen molecules uas muaj ob lub atoms oxygen raug ntaus los ntawm lub teeb ultraviolet. Qhov no ua rau cov atoms sib cais. Cov pa oxygen twg pom nyob hauv stratosphere? Ozone, yam txawv txawv ntawm cov pa oxygen molecule uas muaj ntau nyob rau hauv lub stratosphere, heats cov txheej no raws li nws absorbs zog los ntawm ultraviolet hluav taws xob los ntawm lub hnub.
Yuav ua li cas kev nce nyiaj nce nqi yuav khoom?
Kev nce nqi nce nqi yuav khoom lossis ntau npaum li cas ntawm qee yam tuaj yeem yuav nrog txiaj. Vim tias kev nce nqi nce nqi ntawm cov nyiaj ntsuab, nws txhawb cov neeg siv khoom siv thiab khaws cov khoom lag luam uas qeeb qeeb kom poob nqi.
Qhov twg ntawm cov kuab tshuaj hauv qab no yog siv rau hauv kev sib txuas ntawm chlorofluorocarbon?
Dichloromethane yog ntau yam kev lag luam hnyav. Tus kws tshawb fawb Belgian Frédéric Swarts pioneer lub synthesis ntawm CFCs nyob rau hauv 1890s . CFCs ua li cas? CFCs thiab HCFCs feem ntau yog tsim los ntawm kev sib pauv halogen pib los ntawm chlorinated methanes thiab ethanesCov derivatives brominated yog tsim los ntawm cov tshuaj dawb-radical ntawm chlorofluorocarbons, hloov C-H daim ntawv cog lus nrog C- Br daim ntawv cog lus.
