Cov yam ntxwv yooj yim ntawm Mercury (Hg)
Tshuaj Tshuaj Muaj Zog
Tsuas yog cov hlau uas muaj nyob hauv lub xeev ua kua ntawm chav tsev kub (cim HG, atomic Number 80).
Yooj yim tsim amalgams nrog cov hlau xws li Sulphur, Kub, thiab Nyiaj.
Kev kub siab (13.534 g /M³), siab nto nro, thiab muaj zog hluav taws xob thiab thermal ua haujlwm.
Mercury toxicity
Kua mercury poses kuj muaj kev pheej hmoo tsawg ntawm kev nqus tau lossis tawv nqaij. Txawm li cas los xij, ** Mercury Vapor ** (uas tuaj yeem volatilize nyob rau hauv chav tsev kub) thiab organy mercury teb) yog muaj kev phom sij thiab tuaj yeem ua rau puas tsuaj rau cov hlab ntsha.
Daim Ntawv Thov Lub Ntsiab Tseem Ceeb
Tshuaj ib txwm muaj kev lag luam
Kev lag luam Chlor-Alkali: ZERPACTINE roj thiab sodium hydroxide los ntawm elcury electrolysis (maj mam hloov los ntawm ion-txauv membrane txoj kev).
Cov khoom siv hluav taws xob thiab hluav taws xob: fluorescent teeb, ntsuas hluav taws xob, cov ntshav siab saib xyuas, hloov ntshav siab thiab rov qab los ntawm kev txwv ib puag ncig).
Kev Kho Hniav: Nyiaj txiag Amalgam Hniav Cov Khoom Siv (maj mam hais lus (maj mam phased tawm hauv Tebchaws Europe thiab Amelikas, tseem siv nyob rau qee lub tebchaws tuaj).
Kev Siv Hluav Taws Xob thiab Tshwj Xeeb
Kub Tsuas: mercury yog siv rau kev rho tawm kub los ntawm me-teev kub mines (txwv nruj me ntsis txwv nyob rau hauv MINAMATA lub rooj sib tham).
Kws Tshuaj thiab Chaw Haujlwm Saib Xyuas: Antimicrobial tshuaj tiv thaiv rau cov tshuaj tiv thaiv kab mob (thimerosal), ntsuas hluav taws xob rau cov twj paj nruag.
Tub rog thiab aerospace: mertcury fulminate (spinter tawg), kua hlau txias (rau nuclear reactors).
Kev Lag Luam Thoob Ntiaj Teb thiab Kev Lag Luam
Cov tebchaws tsim loj
Tuam Tshoj: cov neeg tsim khoom loj tshaj plaws hauv ntiaj teb (nrog Mercury Mines hauv Guizhou, Shaanxi, thiab lwm yam).
Spain: Almaden Mercury Mine (tau raug kaw thiab yog tam sim no lub ntsiab lus tseem ceeb).
Lwm tus: Kyrgyzstan, Russia, Mexico, thiab lwm yam.
Nqe thiab Khoom thiab Xav Tau
Nqe Foneduates zoo heev (tsis ntev los no nyob ib puag ncig ** $ {0}} $ 500 / kg **, siab dua li qib siab nyiam 99.99% kim dua). Kev thov tau tsis yeem (vim muaj koob meej ntawm lwm txoj kev thev naus laus zis), tab sis tseem muaj cov kev xav tau kev lag luam thiab kev lag luam tub rog.
Kev ua lag luam
Cov teb chaws xa tawm: Tuam Tshoj, Lavxias, Mexico.
Cov teb chaws txawv teb chaws: Is Nrias teb (rau kev kho hniav thiab kub kho kom zoo nkauj), Asmeskas cov tebchaws (rau kev lag luam eastast).
Cov kev tswj hwm thoob ntiaj teb thiab ua raws cai
Minamata Cov Ntawv Cog Lus
Cov Cai Tseem Ceeb:
Txwv tsis pub tsim muaj Mercury Mines thiab maj mam teeb tawm cov uas twb muaj lawm (Tuam Tshoj tau nres tsheb mercury tsuas).
Txwv tsis pub siv cov mercury hauv cov roj teeb, cov tshuaj pleev ib ce thiab lwm yam.
Nruj me ntsis tswj kev thauj mus los thiab pov tseg ntawm cov mercury khib nyiab.
Kev txwv xa tawm: Daim ntawv tso cai ntawm Ntshuam "los ntawm kev sib sau teb chaws lub teb chaws yog yuav tsum tau rau kev sib cog lus tog.
Kev cai lij choj hauv cheeb tsam
EU: Lub Chaw Tso Cai Tso Cai Tso Cai Txwv txoj kev siv Mercury thiab txwv tsis pub muaj cov kis xwm tshwj xeeb xws li kev tshawb fawb tshwj xeeb).
TEB CHAWS USA: EPA yuav tsum tau xa tawm mus thov daim ntawv tso cai (ua raws li TSCA cov kev cai).
Tuam Tshoj: Nws muaj nyob rau hauv "catalog ntawm cov tshuaj lom neeg lom neeg raug rau txoj kev txwv nruj rau Suav teb", thiab cov neeg xa khoom lag luam yuav tsum tau txais daim ntawv sau npe rau ib puag ncig rau kev xa tawm.
Kev phom sij thiab kev tawm tsam
Kev phom sij lag luam
Kev txheeb xyuas cov kev tsim nyog: yuav ceev faj tiv thaiv kev yuav tsis raug cai rau me me kev siv kub tsuas (ib qho kev kawm siv cov kev tshaj tawm siv).
Kev ua raws li kev thauj mus los: Ntim: un-ntawv pov thawj steel cylinders / tshwj xeeb tsim cov thawv, sau npe "lom" (un 2809).
Cov ntaub ntawv: MSDS, cov khoom lag luam txaus ntshai, ua raws li cov ntawv sau.
Hloov Cov Txheej Txheem Sib Cuam
Kev lag luam hluav taws xob: Cov ntsuas kub digital hloov mercury.
Kev rho tawm kub kub: cov txheej txheem mercury xws li Cyanidation thiab Sodium Borohdrig txoj kev.
Kev tiv thaiv ib puag ncig thiab kev pheej hmoo pheej hmoo
Nws raug nquahu kom hais txog cov saw hlau kom huv rau cov mercury (xws li rho tawm nws los ntawm cov roj fluorescent teeb).
Yav tom ntej cov ncauj lus hauv kev lag luam
Kev Lag Luam Kev Lag Luam: Cov ntawv thov ib txwm muaj tsis kam, tab sis yuav muaj kev thov ntev los ntawm cov haujlwm xws li kev tshawb fawb ua tub rog thiab kev tshawb fawb.
Kev lag luam ncig: Mercury Recovery Technologies (xws li pyrolysis thiab pyrification pyrification) yuav dhau los ua cov khoom siv tseem ceeb.
Kev Kev Teeb Meem: High-purity (ntau dua los yog sib npaug ntawm 99.999%) Mercury tseem tuav tus nqi IRREPRALE muaj nqis xws li cov semiconductors.
Cov Tswv Yim Pab
Cov Koom Tes Thoob Ntiaj Teb: United Nations ib puag ncig txoj haujlwm (UNEP), Secretariat ntawm Minamata cov lus cog tseg.
Kev lag luam tshaj tawm: Kev Ceeb Toom Mercury los ntawm Tebchaws Meskas Geological Kev soj ntsuam (USGS), cov ntaub ntawv los ntawm Tuam Tshoj tsis muaj kev lag luam hauv tuam txhab.
Cov lus qhia rau lwm cov thev naus laus zis: Leej twg yog tus qhia ntawv ntawm cov khoom siv kho mob mercury.
