<prompt> Bheka isigaba esingezansi bese uphendula umbuzo ngemuva kwalokho ngolimi olufanayo nesigaba: Isigaba: Isivumelwano sakhiwe ngamaqembu amaningana ama-halogenated hydrocarbons anciphisa i-ozone ye-stratospheric. Zonke izinto ezicekela phansi i-ozone ezilawulwa yi-Montreal Protocol ziqukethe i-chlorine noma i-bromine izinto eziqukethe i-fluorine kuphela azilimazi ungqimba lwe-ozone. Ezinye izinto ezicekela phansi i-ozone ODSs azikalawulwa yi-Montreal Protocol, kufaka phakathi i-nitrous oxide N2O Ukuze uthole itafula lezinto ezicekela phansi i-ozone ezilawulwa yi-Montreal Protocol bheka:Kweqembu ngalinye le-ODSs, isivumelwano sinikeza uhlelo lwesikhathi lapho ukukhiqizwa kwalezo zinto kufanele kukhishwe khona futhi ekugcineni kuqedwe. Lokhu kufaka phakathi ukuthuthukiswa kweminyaka eyi-10 yamazwe akhonjwe ku-Article 5 yesivumelwano. Umbuzo: Yimuphi iqembu lezinto ezicekela phansi i-ozone ye-stratospheric.  <response>: ama-halogenated hydrocarbons
