Rau ntau tus neeg, qhov pib zoo yog ib nrab ntawm kev sib ntaus sib tua. Kev ua haujlwm thaum sawv ntxov pib tom qab ib khob dej kas fes kub ... Lub sijhawm no, caffeine khi rau qee yam receptors hauv lub hlwb, ua rau lub hlwb tsis tuaj yeem txais "kev qaug zog" cov cim, yog li nws ua rau tib neeg muaj zog txhawb zog.
Txawm li cas los xij, txoj kev tshawb fawb tshiab tau tshaj tawm lus ceeb toom: kev siv lub khob ntawv pov tseg mus ntev los haus kas fes kub lossis dej kub, suav nrog kev noj mov (kub) hauv cov thawv noj su, yuav them tus nqi noj qab haus huv.
Nyob rau hauv ib txoj kev tshawb fawb tshiab luam tawm nyob rau hauv 《 Journal of Hazardous Materials 》 (IF = 9.038), ib pab neeg tshawb fawb los ntawm Indian Institute of Technology pom tias cov kas fes kub lossis lwm yam dej kub hauv cov khob ntawv pov tseg tsis pub dhau 15 feeb Ntau txhiab ntawm cov khoom muaj txiaj ntsig zoo yuav tso tawm rau hauv cov dej haus, uas yog cov khoom yas ...
Peb txhua tus paub txog micro plastics. Nyob rau hauv xyoo tas los no, nrog kev tsim khoom loj thiab siv cov yas, qhov concentration ntawm micro plastics hauv ib puag ncig tau nce ntxiv. Micro plastic pollution tau dhau los ua teeb meem thoob ntiaj teb ib puag ncig nrog ozone depletion, dej hiav txwv acidification, thiab kev hloov pauv huab cua.
Cov kws tshawb fawb tau hais tias yuav luag tsis pom cov micro plastics no tau dhau los ua kev hem thawj rau tib neeg kev noj qab haus huv. Nyuam qhuav pib lub xyoo no, ib pab neeg tshawb fawb hauv Teb Chaws Asmeskas tau tshawb pom micro plastics hauv tib neeg lub cev thawj zaug. Tib neeg txhawj xeeb tias cov pa phem no yuav ua rau mob qog noj ntshav lossis muaj menyuam. Cov kev tshawb fawb tau pom tias cov pa phem micro yas tuaj yeem ua rau mob rau cov tsiaj.
Tus kws sau ntawv ntawm txoj kev tshawb no, Dr. Sudha Goel, Tsev Kawm Ntawv ntawm Environmental Science thiab Engineering, Indian Institute of Technology, tau hais tias: "Ib daim ntawv khob ntim nrog kas fes kub lossis tshuaj yej kub yuav degrade cov microplastic txheej hauv khob hauv 15 feeb. Nws yuav degrade 25,000 micrometers nyob rau hauv loj, cov hais tawm mus rau hauv cov dej kub, ib tug zoo tib yam uas haus peb khob tshuaj yej los yog kas fes nyob rau hauv ib lub khob ntawv pov tseg txhua hnub yuav noj 75,000 cov khoom yas uas tsis pom ntawm qhov muag liab qab. "
Nws tau kwv yees tias xyoo tas los, cov tuam txhab khob ntawv tau tsim kwv yees li 264 billion daim ntawv khob, ntau yam uas siv tshuaj yej, kas fes, kub chocolate, thiab kua zaub. Tus lej no yog sib npaug rau 35 daim ntawv khob rau ib tus neeg hauv ntiaj teb.
Kev nce ntxiv ntawm cov kev pabcuam thoob ntiaj teb kev noj qab haus huv kuj tau ua rau qhov kev thov rau cov khoom siv pov tseg. Hauv lub neej tsis khoom ntau ntxiv thiab kev ua haujlwm, kev xaj khoom xa tuaj tau dhau los ua ib hnub rau ntau tus neeg. Cov thawv ntim khoom noj uas siv tau pov tseg tau muab pov tseg sai li sai tau thaum lawv siv, thiab feem ntau tsis muaj qhov cuam tshuam tsis zoo rau ib puag ncig xws li cov thawv yas thiab styrofoam. Txawm li cas los xij, Sudha tau hais tias, qhov yooj yim no los ntawm tus nqi.
Cov kws tshawb fawb tau hais ntxiv tias: "Micro plastics ua raws li cov khoom muaj kuab paug, xws li ions, cov hlau hnyav hnyav xws li palladium, chromium thiab cadmium, thiab cov organic compounds uas yog hydrophobic thiab tuaj yeem nkag mus rau hauv lub nceeg vaj tsiaj. Kev noj qab haus huv tej zaum yuav raug cuam tshuam.
Cov txheej txheem rhiab heev rau kev sib cais cov tshuaj tau txheeb xyuas cov micro plastics hauv dej kub. Qhov kev ntxhov siab tshaj plaws, kev tsom xam ntawm cov yas zaj duab xis qhia pom muaj cov hlau hnyav hauv ob sab phlu.
Koj tuaj yeem pom tias cov txiaj ntsig kev sim saum toj no yog "kev poob siab", yog li puas muaj cov khoom lag luam uas tuaj yeem hloov PE coated ntawv khob?
Cov lus teb yog yog !PebEPP ntawv khob,OPB noj su box series, thiab lwm yam., tau dhau qhov kev sim thiab ntawv pov thawj ntawm ntau yam kev tso cai (kev sim tshuaj lom neeg kev nyab xeeb kev nyab xeeb, POPs fluorine kuaj, kev kuaj kev tsiv teb tsaws tshwj xeeb, thiab lwm yam), thiab koj tuaj yeem so kom paub tseeb tias cov ntaub ntawv siv los yog ntawv tuaj yeem siv dua. Ua ntej siv composting, paub txog kev rov ua dua tshiab thiab siv cov yas muaj kev nyab xeeb thiab ib puag ncig zoo. Cov khob ntawv ua nrog nws tuaj yeem hloov pauv PE coated ntawv khob.
