Yintoni i ozone

Umaleko ozone umaleko thinnest, kwaye ngaxeshanye kukhanya emoyeni, esimalunga nomphakamo kweekhilomitha ezili-50 ngaphezu komhlaba. Ngokutsho kweengcali, phezu ezahlukeneyo Schroth Umhlaba ubukhulu eyahlukileyo ngokupheleleyo kunye nendawo jikelele. Noko ke, ngokubanzi uyondelelwano lwee- iyeza emoyeni ngalo mzuzu ayinamsebenzi. Umzekelo, ukuba ziqokelele yonke into nwebu enye wayigubungela ngazo iplanethi yethu, ububanzi ye-ozone luya kuba eshumini ze ndlela.

Yintoni na le ozone

Iziyobisi ebizwa ozone yenye iintlobo ezininzi mpilo, equka athom ezintathu (O³). Le nto senziwa zikhabane embindini stratosphere. Kulapha phantsi inyathelo ultraviolet radiation solar cazulula mpilo ibe athom ezimbini kamva angene reactions ezintsonkothileyo ngakumbi molecule, yaye isiphumo a O³ trihydric.

Oko umele ukwazi

Umaleko ozone iyaziwa ukuba lidlale indima ebalulekileyo ekuqinisekiseni imimiselo efanelekileyo kuphila emhlabeni. Kuyinto ngenxa kuye, ukuze ndithethe, ababhlokiweyo yingozi zonke izinto eziphilayo, yemisebe ilanga. Sonke siyazi ukuba yelanga eyingozi kunganciphisa amajoni omzimba, ukuba ukutsha kwaye kungakhokelela kwizifo ezinobungozi ezifana ezifana nomhlaza. Izityalo kunye nezilwanyana, olu hlobo impembelelo nalo nezinzima. Kwelinye icala, ukuba olu hlobo yokhuseleko awayeyiphosa, njengoko zithi iinzululwazi, ubomi umhlaba uza kuba kunokwenzeka kuphela kwiilwandle kunye neelwandle, apho izinto ikholam amanzi kufihlwa kwimiphumo eyingozi kwelanga. Ngenxa yoko, sinokuthi ngenxa Qiniseka ukuba ozone Uyingweletshetshe lokwenyaniso emhlabeni, elikhusela ukuba amawaka eminyaka. Iingcali ayikwazi, ngelishwa, bathi ngqo xa ndakubumba. Noko ke, ngokutsho data yakutshanje xi weli emoyeni iwile kakhulu kule minyaka idlulileyo embalwa, nto leyo eyakhokelela ekubeni ekubunjweni ekuthiwa- imingxuma ozone. I inkulu umngxuma loo kule ndawo phezu Antarctica.

Izizathu ukuze kwakhiwe mngxuma ozone

Iingcali zikholelwa ukuba esona sizathu siphambili le meko, kuqala kwiinto zonke, ukuba umsebenzi industrial yomntu. Eyona nto kukuba ngoku kukho kakhulu ukukhutshwa isikali iikhemikhali eziyingozi kwi-atmosfera. Nokuba ngoku uluntu luza kupheza yonke imisebenzi yayo, ngokupheleleyo kweziyobisi iya kubuyiselwa kuphela emva kweminyaka engama-50.

I-Vienna Convention on Ozone Protection Ulwaleko

Eli lilinge lokuqala kunye karhulumente ukukhusela ozone yenziwa ngowe-1985, xa amazwe ezisayiniweyo ekuthiwa-Vienna Convention. Esi sixeko ezaziswe ngokusemthethweni ingqikelelo ulondolozo statosfery site, yaye esatyikitywa ngamazwe amaninzi. Ukuzibophelela kwezi mazwe ziquka ukuyilwa kwento -nkqubo wesizwe kunye namanyathelo okumiselwa ezilandelayo eziya ezijoliswe ekunciphiseni ifuthe elibi umoya ehlabathini. Kubalulekile ukuqaphela ukuba i-Convention akazange ukunika ixesha ethile inkqubo okanye naziphi ukwayo kumazwe ezingaphumeleliyo ukuthobela imimiselo yalo substantive.
