Uthotho olungenaMercury luyeza.

ISivumelwano saseMinamata malunga neMercury, esatyikitywa eKumamoto ngummeli karhulumente weRiphabliki yabantu baseTshayina nge-10 ka-Okthobha 2013. NgokweSivumelwano saseMinamata, ukusukela ngo-2020, amaqela akwisivumelwano aye athintela ukuveliswa nokungeniswa kunye nokuthunyelwa kweemveliso ezine-mercury.

I-Mercury yinto eyenzeka ngokwendalo efumaneka emoyeni, emanzini, nasemhlabeni, kodwa ukusasazwa kwayo kwindalo kuncinci kakhulu kwaye ithathwa njengesinyithi esinqabileyo.

Kwangaxeshanye, i-mercury yinto engabalulekanga kakhulu, enobungozi kakhulu, efumaneka kakhulu kwiindawo ezahlukeneyo zokusingqongileyo nakwiindlela zokutya (ingakumbi iintlanzi), kwaye imikhondo yayo isasazeke kwihlabathi liphela.

I-Mercury inokuqokelelana kwizinto eziphilayo kwaye ifunxwa lula lusu, indlela yokuphefumla kunye nendlela yokugaya ukutya.

Isifo iMinamata luhlobo lwetyhefu yemercury. Imercury itshabalalisa inkqubo yemithambo-luvo ephakathi kwaye inefuthe elibi emlonyeni, kwiinwebu zangaphakathi namazinyo.

Ukuvezwa ixesha elide kwiindawo ezine-mercury eninzi kunokubangela umonakalo engqondweni nokufa.

Nangona i-mercury ibila kakhulu, umphunga we-mercury ogcwele kubushushu begumbi ufikelele kwinani eliphindwe kaninzi le-dose enetyhefu.

Isifo saseMinamata luhlobo lwetyhefu yemercury engapheliyo, ebizwa ngegama lelali yokuloba eyafunyanwa okokuqala ngeminyaka yoo-1950 kufutshane neMinamata Bay eKumamoto Prefecture, eJapan.

Ngokwemimiselo yeSivumelwano saseMinamata, iqela likaRhulumente liza kuyithintela imveliso, ukungenisa kunye nokuthumela ngaphandle iimveliso ezongezwe kwi-mercury ngo-2020, umzekelo, ezinye iibhetri, izibane ezithile ze-fluorescent, kunye nezinye izixhobo zonyango ezongezwe kwi-mercury ezifana nee-thermometers kunye ne-sphygmomanometers.

Oorhulumente abaNgena kwiSivumelwano saseMinamata bavumile kwiSivumelwano saseMinamata ukuba ilizwe ngalinye liza kuphuhlisa isicwangciso selizwe sokunciphisa nokuphelisa i-mercury kancinci kancinci kwiminyaka emithathu ukususela kumhla wokuqala ukusebenza kwesivumelwano.

I-thermometer yeglasi, egama layo lesayensi liyi-triangular rod thermometer, yityhubhu emfutshane yeglasi emzimbeni wonke, ebuthathaka. Igazi emzimbeni wonke yinto yesinyithi esinzima ebizwa ngokuba yi-"mercury".

Emva kokuba iingcali “zitsale intamo”, “iqamza”, “ukuncipha komphimbo”, “iqamza lokutywina”, “ukudibanisa i-mercury”, “intloko yokutywina”, “indawo emiselweyo”, “i-semicolon”, “ukuprinta okungenayo”, “uvavanyo” “, “Ukupakisha” iinkqubo ezingama-25 ezenziwe ngononophelo, zazalwa ehlabathini. Ingachazwa “njengamawaka emizamo”.

Eyona nto incinci kukuba phakathi kwetyhubhu yeglasi ye-capillary kunye ne-glass bubble embindini, kukho indawo encinci kakhulu, ebizwa ngokuba yi-"shrink", kwaye i-mercury ayilula ukuyidlula. I-mercury ayizukuwa emva kokuba i-thermometer iphume emzimbeni womntu ukuqinisekisa umlinganiselo ochanekileyo. Ngaphambi kokusetyenziswa, abantu badla ngokuphosa i-mercury ngaphantsi kwesikali se-thermometer.

I-China iza kuyeka ukuvelisa ii-thermometer ze-mercury ngo-2020.

Ukuze siqinisekise ukuchaneka, sisebenzisa ii-alloys endaweni ye-mercury. Ungafumana iimveliso ezingenayo i-mercury kwiwebhusayithi yethu.
