Geneva, Kaum Ib Hlis 7, 2025 - Lub Rooj Sib Tham Rau Lub Rooj Sib Tham (COP-6) rau Minamata Convention on Mercury tau txais kev hloov kho thaj chaw, teeb tsa 2034 lub sijhawm kawg rau kev tshem tawm kev kho hniav thoob ntiaj teb-cov khoom siv mercury- siv ntev thiab so hniav hniav-txog kho. Qhov kev tshawb fawb no- qhov kev txiav txim siab thim rov qab ua qhov kev txiav txim siab hloov mus rau kev kho hniav tsis muaj mercury, hais txog kev noj qab haus huv hnyav thiab kev pheej hmoo ntawm ib puag ncig los ntawm cov khoom siv.
Cov haujlwm tseem ceeb hauv cheeb tsam twb tab tom ua. Tuam Tshoj tau txwv tsis pub siv cov tshuaj kho hniav rau cov menyuam yaus hnub nyoog qis dua 15 xyoos, cev xeeb tub, thiab cov poj niam cev xeeb tub, nrog rau kev tswj hwm nruj ntawm cov mercury txwv tsis pub hauv kev kho hniav. EU yuav txwv kev xa tawm ntawm kev kho hniav amalgam hauv 2025 thiab tso tseg tag nrho cov khoom tsim los ntawm 2026, ua kom nws hloov mus rau lwm cov ntaub ntawv. Kev kho hniav amalgam, uas muaj ntau dua 50% mercury, tso tawm cov pa phem thaum zom thiabkev ua plees ua yi, paug huab cua, dej, thiab av thoob ntiaj teb.
Rau cov hniav hniav thiab kho hniav kho hniav, qhov kev hloov kho tsav ceev ceev cov mercury - lwm yam dawb. Resin composites thiab iav ionomers-cov nqi pov thawj- zoo thiab ruaj khov- yog cov kev hloov pauv, muab cov txiaj ntsig zoo li kev khaws cov hniav thiab cov tshuaj fluoride tso tawm kom tsis txhob muaj kab noj hniav. Cov thawj coj hauv kev lag luam tau sau tseg tias qhov kev hloov pauv tau ua raws li qhov xav tau nce ntxiv rau biocompatible, tshuaj kho hniav zoo nkauj, thaum tshem tawm ntev - cov nqi ib puag ncig txuas nrog cov pov tseg mercury.
Raws li ntau tshaj 150 tog siv cov phiaj xwm kev nqis tes ua hauv tebchaws, kev lag luam hniav hniav nkag mus rau lub sijhawm ruaj khov. Qhov kev hloov pauv tsis yog tsuas yog tiv thaiv pej xeem kev noj qab haus huv thiab ecosystems xwb tab sis kuj tseem ua kom muaj kev hloov pauv tshiab hauv cov khoom siv kho hniav digital thiab biomimetic, paving txoj hauv kev kom muaj kev nyab xeeb dua, zoo dua kev hloov cov hniav thoob ntiaj teb.
