CFC 11, lossis R-11 muaj peev xwm tshaj plaws ntawm cov chlorocarbons vim tias muaj peb chlorine atoms hauv cov molecule. … Hydrofluorocarbons (HFC) tsis muaj cov ntsiab lus chlorine, yog li lawv ODP yog qhov tseem ceeb xoom.
Puas tsis ua rau ozone depletion?
Nitrous oxide, zoo li CFCs, ruaj khov thaum tso tawm hauv av, tab sis tawg thaum nws mus txog stratosphere los tsim lwm cov pa roj, hu ua nitrogen oxides, uas ua rau ozone- rhuav tshem cov tshuaj tiv thaiv.
Koj ua li cas xam ozone depletion peev xwm?
Lub ODP kwv yees yog cov khoom ntawm "halogen loading peev" (HLP) thiab "halogen efficiency factor" (HEF) . Hauv kev xyaum, H=Cl, Br. Lub HLP tsuas yog hais txog lub nra ntawm halogen hauv lub stratosphere, txheeb ze ntawm CFC-11 rau kev sib npaug emissions hauv kton yr-1.
Qhov twg ntawm cov tub yees hauv qab no muaj peev xwm ozone depletion ntau tshaj xoom?
CFCs muaj peev xwm ozone ntau tshaj plaws ntawm txhua hom tub yees vim yog peb lub chlorine atoms nws muaj. HFCs thiab HFOs tsis yog ozone depleting vim lawv tsis muaj chlorine atoms. Lawv ob leeg muaj ODP ntawm 0. Tab sis CFCs thiab HCFCs, muaj chlorine atoms.
Yuav ua li cas hauv qab no muaj peev xwm ua kom lub ozone deplete?
nplooj ntawv no muab cov ntaub ntawv qhia txog cov khoom sib txuas uas pom tau tias yog cov tshuaj ozone depleting (ODS.
