ओज़ोन परत

ozon parat(aangrezi: Ozone Layer) prithvi ke dharatal se 20-30 kimi ki ooanchaee par vayumandal ke samatap mandal kshetr mean ozon gais ka ek jhina sa avaran hai. vayumandal ke ayatan kean sandarbh mean ozon parat ki saandrata lagabhag 10 pipiem hai. yah ozon parat paryavaran ki rakshak hai. ozon parat hanikarak parabaiangani kiranoan ko prithvi par ane se rokati hai.

ozon parat ka ksharan

badhate audyogikaran ke parinamasvaroo vayumandal mean kuchh aise rasayanoan ki matra badh gayi, jinake dushprabhav se ozon parat ko khatara utpann ho gaya hai. aise rasayanoan mean 'kloroan phloro karban' (si.eph.si), klorin evan naitras aauksaid gaisean pramukh hai. ye rasayan ozon gais ko aauksijan mean vighatit kar dete haian, jisaki vajah se ozon parat patali ho jati hai aur usamean chhidr ho jata hai. yahaan tak ki ozon parat mean chhidr ka akar yoorop ke akar ke barabar ho gaya hai. ozon parat mean chhidr ho jane ke karan soory ki hanikarak parabaiangani kiranean aur rediyo vikiran dharati tak pahuanch jate haian tatha jiv-jantuoan evan vanaspatiyoan par apana kuprabhav chho date haian.

rephrijareshan udyog mean pramukh roop se prayukt hone vali klora phalora karban (si.eph.si.), klorin, phlorin tatha karban ka yaugik hai. soory ki parabaiangani kiranean vayumandal mean vidyaman si.eph.si. ko to d deti hai tatha alag huee klorin evan phlorin ozon gais ke anuoan ko aauksijan mean vighatit kar deti hai. dhyatavy hai ki klorin ka ek paramanu 1,00,000 ozon anuoan ko nasht karane ki kshamata rakhata hai. ozon parat ko bhedane mean naitras aauksaid gais bhi pramukh bhoomika nibhati hai. yah gais mukhy roop se nayalan-66 evan nayalan-612 ke utpadan ke dauran utpann hoti hai kyoanki uparokt nayalan ke utpadan mean ediyik aml prayukt hota hai.

garmi ke mahinoan mean ozon ka hras apekshakrit tezi se hota hai. ozon parat ke hras ki dar prati dashak uttari aur dakshini madhy akshaansh mean lagabhag 5 pratishat hai. yadi ozon parat ke hras ki gati yahi rahi to agale 70 se 100 varsho mean ozon parat ko 11 pratishat se 16 pratishat nasht ho jaega.

ozon parat ke sanrakshan ke upay

ozon parat ka sanrakshan ek vaishvik samasya hai. vishv ke vaijnanikoan evan paryavaranavidoan ne isake sanrakshan ke upayoan ko gambhirata se liya hai. ozon parat ko bachane ke sarvabhaumik prayasoan ke tahat sarvapratham 1985 mean viyana sammelan tatha 1987 mean 'maantriyal protokal' ke roop mean rashtroan dvara antarrashtriy samajhaute ko manjoori di gee. si.eph.si. par samayabaddh tarike se rok lagana hi maantriyal protokal ka pramukh uddeshy tha. maantriyal protokal mean varsh 2000 tak kloro phlora karban ke upayog par poorn pratibandh lagana shamil tha. bharat mean bhi is protokal ke anuroop samasya se nipatane ke lie vachanabaddhata vyakt ki hai. maantriyal protokal ke bad march 1989 mean phraans ke tatkalin pradhanamantri ne punah ozon parat ki suraksha ke sambandh mean vichar-vimarsh karane ke lie 24 deshoan ka ek sammelan bulaya, jisamean sanyukt rajy amarika ke tatkalin rashtrapati jarj bush sahit bharat ke tatkalin pradhanamantri rajiv gaandhi ne bhi bhag liya tha.
