Thiab vim tias lawv me me (tsawg dua 1 millimeter), microbeads tsis lim tawm ntawm cov chaw kho dej khib nyiab. Qhov no txhais tau hais tias lawv xaus rau hauv cov dej hauv cov dej loj.
Raws li kev tshawb fawb luam tawm los ntawm American Chemical Society nyob rau hauv phau ntawv journal Environmental Science & Technology, US tsev neeg ntxuav tawm 808 trillion microbeads txhua hnub. Ntawm cov nroj tsuag rov ua dua tshiab, 8 trillion microbeads xaus ncaj qha rau hauv cov dej. Qhov no txaus los npog 300 lub tsev hais plaub ntaus pob tesniv.
Txawm hais tias feem ntau cov microbeads los ntawm cov nroj tsuag rov ua dua tsis tuaj yeem ncaj qha rau hauv cov dej, cov khoom yas me me muaj txoj hauv kev uas nws thiaj li xaus rau hauv dej thiab pas dej. Qhov seem 800 trillion microbeads xaus rau hauv sludge, uas tom qab ntawd siv los ua chiv rau cov nyom thiab av, qhov twg cov microbeads tuaj yeem nkag mus rau hauv dej los ntawm cov dej ntws.

Lub ntiaj teb no daws qhov teeb meem microbead li cas?
Txoj kev zoo tshaj plaws los tiv thaiv microbead paug, raws li kev tshawb fawb luam tawm los ntawm American Chemical Society, yog tshem tawm microbeads los ntawm cov khoom noj.
Hauv xyoo 2015, Tebchaws Meskas tau tshaj tawm txoj cai txwv tsis pub siv cov yas microbeads hauv xab npum, tshuaj txhuam hniav thiab ntxuav lub cev. Txij li Thawj Tswj Hwm Barack Obama tau kos npe rau hauv txoj cai lij choj, cov tuam txhab loj xws li Unilever, Procter & Gamble, Johnson & Johnson thiab L'Oreal tau cog lus tias yuav tshem tawm kev siv cov microbeads hauv lawv cov khoom, txawm li cas los xij nws tsis paub meej yog tias txhua lub npe tau ua raws li qhov kev cog lus no. .
Tom qab ntawd, cov tswv cuab ntawm British Parliament tau hu rau cov khoom uas muaj microbeads. Canada tau tshaj tawm txoj cai zoo sib xws rau Asmeskas, uas xav kom lub teb chaws txwv tsis pub txhua yam khoom siv nrog microbeads los ntawm Lub Xya Hli 1, 2018.
Txawm li cas los xij, cov neeg tsim cai lij choj tsis paub txog txhua yam khoom lag luam uas muaj microbeads, tsim kom muaj qhov tsis txaus ntseeg hauv Teb Chaws Asmeskas txwv tsis pub cov tuam txhab lag luam txuas ntxiv muag qee cov khoom lag luam nrog microbeads, suav nrog cov tshuaj ntxuav tes, cov khoom siv sandblasting, thiab tshuaj pleev ib ce.
Kuv tuaj yeem pab tiv thaiv cov kab mob microbead li cas?
Cov lus teb yog yooj yim: tsis txhob siv thiab yuav cov khoom uas muaj microbeads.
Koj tuaj yeem tshawb xyuas koj tus kheej yog tias cov khoom muaj microbeads. Saib cov khoom xyaw nram qab no ntawm daim ntawv lo: polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), thiab nylon (PA).
Yog tias koj xav tau cov khoom siv exfoliating, nrhiav cov khoom qub xws li oats, ntsev, yogurt, qab zib, lossis kas fes hauv av. Tsis tas li ntawd, koj tuaj yeem sim lwm txoj hauv kev zoo nkauj rau microbeads: cov xuab zeb dag.
