Uchungechunge olungenayo i-Mercury luyeza.

I-Minamata Convention on Mercury, esayinwe eKumamoto ngummeleli kahulumeni wePeople's Republic of China ngo-Okthoba 10, 2013. Ngokusho kweMinamata Convention, kusukela ngo-2020, izivumelwano zenkontileka ziye zavala ukukhiqizwa nokungenisa kanye nokuthunyelwa kwamanye amazwe kwemikhiqizo equkethe i-mercury. .

I-Mercury iyinto eyenzeka ngokwemvelo etholakala emoyeni, emanzini, nasenhlabathini, kodwa ukusatshalaliswa kwayo ngokwemvelo kuncane kakhulu futhi kubhekwa njengensimbi eyivelakancane.

Ngesikhathi esifanayo, i-mercury iyinto enobuthi kakhulu engabalulekile, etholakala kabanzi emithonjeni yezemvelo ehlukahlukene kanye namaketanga okudla (ikakhulukazi izinhlanzi), futhi iminonjana yayo isakazwa emhlabeni wonke.

I-Mercury inganqwabelana ezintweni eziphilayo futhi imuncwa kalula yisikhumba, umgudu wokuphefumula kanye nomgudu wokugaya ukudla.

Isifo saseMinamata siwuhlobo lwe-mercury poisoning. I-Mercury ibhubhisa isimiso sezinzwa esiyinhloko futhi inomphumela omubi emlonyeni, ulwelwesi lwamafinyila namazinyo.

Ukuchayeka isikhathi eside ezindaweni eziphakeme zemercury kungabangela ukulimala kwengqondo nokufa.

Naphezu kweqophelo eliphezulu lokubilisa le-mercury, umhwamuko wemercury osuthiswe ezingeni lokushisa legumbi usufinyelele isilinganiso esiphindwe kaningi kunoshevu.

Isifo saseMinamata siwuhlobo lwe-mercury poisoning engapheli, ebizwa ngokuthi idolobhana lokudoba elatholwa okokuqala ngawo-1950 eduze kwaseMinamata Bay eKumamoto Prefecture, eJapane.

Ngokwezinhlinzeko zeSivumelwano saseMinamata, iqembu loMbuso lizovimbela ukukhiqizwa, ukungenisa nokuthekelisa kwemikhiqizo engezwe nge-mercury ngo-2020, isibonelo, amanye amabhethri, izibani ezithile ze-fluorescent, kanye nezinye izinto zokwelapha ezingezwe nge-mercury ezifana nama-thermometers nama-sphygmomanometers. .

OHulumeni Bezinkontileka bavumelana kuSivumelwano saseMinamata ukuthi izwe ngalinye lizokwenza uhlelo lukazwelonke lokunciphisa nokuqeda kancane kancane i-mercury phakathi neminyaka emithathu kusukela ngosuku lokuqalisa ukusebenza kwesivumelwano.

I-thermometer yengilazi, igama layo lesayensi i-thermometer yenduku engunxantathu, iyishubhu lengilazi elifushane eligcwele umzimba wonke, elintekenteke. Igazi emzimbeni wonke liyingxenye yensimbi enamandla ebizwa ngokuthi "i-mercury".

Ngemuva kokuthi izingcweti "zidonse intamo", "ibhamuza", "ukuncipha komphimbo", "ibhamuza lokuvala", "i-mercury ehlanganisayo", "ikhanda elivala", "iphoyinti eligxilile", "semicolon", "ukuphrinta okungena ngaphakathi", "ukuhlola" " , "Ukupakisha" izinqubo ezingu-25 ezenziwe ngokucophelela, zazalwa emhlabeni. Ingachazwa ngokuthi “izinkulungwane zemizamo”.

Ubuqili buwukuthi phakathi kwethubhu yeglasi ye-capillary kanye ne-bubble yengilazi phakathi, kukhona indawo encane kakhulu, ebizwa ngokuthi "shrink", futhi i-mercury akulula ukuyidlula. I-mercury ngeke yehle ngemva kokuba i-thermometer ishiya umzimba womuntu ukuze kuqinisekiswe ukulinganisa okunembile. Ngaphambi kokusetshenziswa, abantu bavame ukuphonsa i-mercury ngaphansi kwesikali se-thermometer.

I-China izoyeka ukukhiqiza ama-thermometers e-mercury ngo-2020.

Ukuze siqinisekise ukunemba, sisebenzisa ama-alloys esikhundleni se-mercury.Ungathola imikhiqizo engenayo i-mercury kuwebhusayithi yethu.
