Njengoba ukunakekelwa kwezempilo kuqhubeka nokuthuthuka, namathuluzi asetshenziswayo ukunikeza ukunakekelwa kweziguli okuphephile nokunembe kakhudlwana ayathuthuka. Ushintsho olukhulu eminyakeni yamuva nje kube ukushenxa kumadivayisi endabuko asekelwe ku-mercury kuya kwezinye izindlela ezinobungani nemvelo neziphephile ezigulini. Phakathi kwalokhu, i-sphygmomanometer engenayo i-mercury iyavela njengendinganiso entsha ekuqapheni umfutho wegazi emtholampilo nasekhaya.
Ngakho-ke kungani imitholampilo kanye nochwepheshe bezokwelapha emhlabeni wonke benza ushintsho?
Umthelela Wezemvelo weAmadivayisi e-Mercury
I-Mercury ibilokhu iqashelwa njengento eyingozi, kokubili kubantu kanye nemvelo. Ngisho nokuchitheka okuncane kungaholela ekungcoleni okukhulu, okudinga izinqubo zokuhlanza ezibizayo. Ukulahlwa kwemishini esekelwe kwi-mercury kulawulwa ngokuqinile, okwengeza ubunzima kanye nomthwalo wemfanelo ekuphathweni kwemfucuza yezempilo.
Ukukhetha i-sphygmomanometer engenayo i-mercury kususa ingozi yokuchayeka ku-mercury futhi kwenza kube lula ukuthobela imithethonqubo yemvelo. Lokhu akusizi nje kuphela ukuvikela abasebenzi neziguli kodwa futhi kuhambisana nemizamo yomhlaba wonke yokunciphisa ukusetshenziswa kwe-mercury ekunakekelweni kwezempilo.
Ukuphepha Okuthuthukisiwe Kweziguli Nabahlinzeki Bezempilo
Ezindaweni zomtholampilo, ukuphepha akuxoxiswana ngakho. Ama-sphygmomanometer e-mercury avamile abeka ingozi yokuphuka kanye nokuvezwa ngamakhemikhali, ikakhulukazi ezindaweni ezimatasa noma ezicindezelayo. Ezinye izindlela ezingenayo i-mercury zenzelwe ukuba ziqine kakhulu futhi zingachitheki, zinciphise ingozi yezingozi ngesikhathi sokusetshenziswa kwansuku zonke.
Ukushintshela ku-sphygmomanometer engenayo i-mercury kuqinisekisa indawo ephephile yabasebenzi bezempilo, iziguli, ngisho namalungu omndeni ezimweni zokunakekelwa ekhaya. Lokhu kubaluleke kakhulu ekunakekelweni kwezingane kanye nabantu asebekhulile lapho ukubekeka engcupheni kwezinto ezinobuthi kuphezulu khona.
Ukunemba Nokusebenza Ongakwethemba
Enye yezinto ezivame kakhulu phakathi kwabasebenza ngokuhlinzwa ukuthi ngabe amadivayisi angenayo i-mercury angafanelana yini nokunemba kwamamodeli endabuko. Ngenxa yentuthuko kwezobuchwepheshe, ama-sphygmomanometer anamuhla angenayo i-mercury anembe kakhulu futhi ahlangabezana noma adlula amazinga omhlaba wonke okuqapha umfutho wegazi.
Kusukela ekufundweni kwedijithali kuya emiklamo ye-aeroid enezindlela zokulinganisa ezithuthukisiwe, ezinye izindlela zanamuhla zinikeza imiphumela ethembekile ngaphandle kokuhle kwe-mercury. Amamodeli amaningi afaka nezici ezithuthukisa ukusetshenziswa, njenge-cuffs ezilungisekayo, izibonisi ezinkulu, kanye nemisebenzi yememori.
Kulula Ukusetshenziswa Nokunakekelwa
Enye inzuzo ephawulekayo yezinketho ezingenayo i-mercury ukuthi kulula ukuzisingatha. Ngaphandle kwesidingo sokuqapha ukuvuza, ukuhlola amazinga e-mercury, noma ukulandela izinqubo eziyinkimbinkimbi zokulahla, ochwepheshe bezempilo bonga isikhathi futhi banciphise izinkinga zokusebenza.
Ukugcinwa kwesakhiwo nakho kwenziwe lula. Ama-sphygmomanometer amaningi angenayo i-mercury alula, ayaphatheka, futhi akhiwe ngezingxenye eziqinile, okwenza afaneleke kokubili emitholampilo ezinzile kanye nabahlinzeki bezempilo abahambahambayo.
Ukuhlangabezana Nezindinganiso Zezempilo Zomhlaba Wonke
Ukuthuthela kumadivayisi angenawo i-mercury akuyona nje into eyenzeka—kusekelwe yiziphathimandla zezempilo zomhlaba wonke. Izinhlangano ezifana ne-World Health Organization (WHO) kanye ne-United Nations Environment Programme (UNEP) zivumile ukususwa kwamadivayisi ezokwelapha ane-mercury ngaphansi kwezimiso ezifana ne-Minamata Convention on Mercury.
Ukusebenzisa i-sphygmomanometer engenayo i-mercury akuyona nje ukukhetha okuhlakaniphile—kuyisinqumo esinomthwalo wemfanelo esivumelana nezinqubomgomo zezempilo zamanje kanye nemigomo yokusimama.
Isiphetho: Khetha Okuphephile, Okuhlakaniphile, Nokuqhubekayo
Ukufaka ubuchwepheshe obungenalo i-mercury emtholampilo wakho wokunakekelwa kwempilo kunikeza izinzuzo ezahlukahlukene—kusukela ekuvikelweni kwemvelo kanye nokuphepha okwandisiwe kuya ekulandeleni imithetho kanye nokusebenza okuthembekile. Njengoba izikhungo eziningi zishintshela kubaqaphi bengcindezi yegazi banamuhla, kusobala ukuthi ukungabi nalo i-mercury kuyikusasa lokunakekelwa kwempilo okunembile nokunezimiso zokuziphatha.
Ukulungele ukushintsha? Xhumana noI-Sinomedukuhlola izixazululo ezisezingeni eliphezulu, ezingenayo i-mercury ezenzelwe izidingo zakho zezokwelapha.
