Dej hiav txwv muaj kuab paug
Marine pollution yog ib qho teeb meem tseem ceeb hauv ntiaj teb niaj hnub no. Raws li lub plawv ntawm lub ntiaj teb, dej hiav txwv occupies txog 75% ntawm lub ntiaj teb cheeb tsam. Tab sis piv rau av litter, marine litter yog yooj yim overlooked. Txhawm rau hu rau tib neeg kev mloog rau lub ntiaj teb ib puag ncig, Australian International Environmental Protection Organization tau pib ua haujlwm thoob ntiaj teb - World Cleanup Day, uas yog nyob rau peb lub lis piam ntawm lub Cuaj Hli txhua xyoo, txhawm rau tiv thaiv lub ntiaj teb av tawm ntawm kev tswj hwm. los ntawm kev cuam tshuam cov kev hloov hauv tib neeg tus cwj pwm. Qhov teeb meem ntawm khib nyiab thiab marine litter
Ua tib zoo saib xyuas cov kab mob microfiber
Hauv cov khib nyiab hauv hiav txwv, cov khoom paug yas muaj txog li 85%, thiab cov yas no tau decomposed mus rau hauv cov khoom me me los ntawm nthwv dej thiab hnub ci ntau xyoo thiab muaj nyob hauv dej hiav txwv ntev. Kev sib sau ntawm microfibers hauv cov khoom noj khoom haus ua rau muaj kev hem thawj loj rau txhua lub neej hauv hiav txwv, thiab lawv cov emissions muaj feem xyuam nrog peb lub neej txhua hnub.
Microplastics hauv tib neeg cov ntshav
Txoj kev tshawb no qhia tau hais tias microplastics hauv tib neeg cov ntshav
Nyob rau lub Peb Hlis, ib txoj kev tshawb fawb luam tawm nyob rau hauv phau ntawv journal Environment International qhia thawj zaug qhov tseeb tias tib neeg cov ntshav muaj microplastics.
Cov kws tshawb fawb hauv Netherlands tau tsim qhov kev sim tshiab los nrhiav cov khoom siv microplastic uas tuaj yeem nqus tau los ntawm cov kab mob hauv tib neeg lub cev, thiab lawv pom tias 17 ntawm 22 tus neeg laus noj qab haus huv tuaj yeem pab dawb, lossis 77%, muaj cov microplastics hauv lawv cov ntshav. Feem ntau cov microplastic nyob rau hauv cov ntshav kuaj no yog polyethylene terephthalate (PET), uas yog dav siv nyob rau hauv textiles thiab zaub mov thiab dej ntim, ua raws li polymeric styrene (PS), polyethylene (PE) thiab polymethyl methacrylate (PMMA).
Cov kws tshawb fawb ntawm UK's National Oceanography Center muaj kev txhawj xeeb vim tias microplastic hais txog qhov loj me no tau pom hauv chav kuaj ua rau mob thiab cellular puas tsuaj nyob rau hauv kev sim. Ntshav yog qhov kawg ntawm cov saw ntawm microplastics. Es tsis txhob nrhiav microplastics thaum kawg thiab muab lus ceeb toom, nws yog qhov zoo dua los tswj lawv los ntawm qhov chaw. Ib qho ntawm cov microplastics feem ntau ze rau tib neeg lub neej txhua hnub yog microfibers los ntawm textiles.
Microplastic Pollution
Microplastics tsis zoo cuam tshuam rau tib neeg thiab qhov xwm txheej ntawm txhua yam
Xyoo 2022, ib daim ntawv tshaj tawm txog kev zam zam tau pom tias textiles tso tawm 200,000 txog 500,000 tons ntawm cov hluavtaws fibers rau hauv ib puag ncig marine thoob ntiaj teb, ua rau lawv yog qhov loj tshaj plaws ntawm cov pa phem hauv dej hiav txwv.
Los ntawm qhov kev xav ntawm ib puag ncig marine, ntau yam teeb meem ib puag ncig tau tshwm sim nyob rau xyoo tas los no, suav nrog kev ua paug ntawm cov yas thiab microfiber, kev nuv ntses hauv hiav txwv tob, kev puas tsuaj ib puag ncig, thiab lub zog tauj dua tshiab hauv hiav txwv. Ntawm cov teeb meem no, microfiber paug yog ib qho teeb meem loj tshaj plaws, thiab ntau yam kev tshawb fawb tau tshawb pom thiab ua pov thawj qhov tsis zoo ntawm microfibers rau cov kab mob thiab ib puag ncig.
2.9% ntawm cov ntses larvae thiab dej microbes noj thiab khaws cov microplastics thiab microfibers indigestible.
Kuj tseem muaj txog 29 txog 280 cov khoom ntawm microplastics, feem ntau yog microfibers, ib square meter ntawm atmospheric plua plav thiab huab cua ib hnub twg.
Peb caug-tsib feem pua ntawm cov pa phem microplastic los ntawm kev ntxuav cov khoom siv hluavtaws, nrog kev ntxuav cov pa tawm sib npaug rau kev pov tseg 50 billion cov khoom yas rau hauv dej hiav txwv txhua xyoo.
Cov kev tshawb fawb tau pom cov microplastics hauv tib neeg cov quav thiab cov ntshav, qhia tias microplastics tuaj yeem ntws hauv cov ntshav, lymphatic system thiab txawm tias lub siab, thiab cov kev tshawb fawb tshiab tau pom tias muaj cov microfibrils nyob rau hauv lub ntsws ntawm cov neeg nyob.
Synthetic fibers xws li polyester, nylon, acrylic thiab lwm yam ntaub ntawv yog feem ntau siv los ua ntau yam textiles vim lawv zoo softness, absorbency, thiab dej kuj. Tab sis qhov tseeb, polyester, nylon, acrylic, thiab lwm yam yog txhua yam ntawm cov yas ua los ntawm roj av los yog natural gas. Lawv cov ntsiab lus tsis txawv ntawm cov hnab yas, lub raj mis dej haus, thiab lwm yam, thiab lawv txhua tus tsis yog biodegradable pollutants.
Microfiber & Microplastic Dab tsi yog non-biodegradable textile fabrics txhais li cas?
Cov pa phem uas tsis yog biodegradable yog hais txog cov pa phem uas tsis tuaj yeem hloov mus rau hauv ib puag ncig yam tsis muaj teeb meem tom qab tshuaj lom neeg degradation, photochemical degradation thiab lom degradation nyob rau hauv ib puag ncig ntuj. Qhov ntawd yog hais tias, textiles ntawm tib tus qauv tsim, ua los ntawm cov khoom siv ntuj tsim tuaj yeem maj mam pwm thiab ua ib feem ntawm cov xwm txheej tom qab tau tso rau hauv kaum ob peb xyoos, thaum cov khoom siv hluavtaws tsuas yog plua plav thiab tawg - lawv tuaj yeem nrog. Koj tau ntev lawm, ntev npaum li cas txawm tias koj tau poob sib nrug los, koj yeej ib txwm tso ib txoj kab. Qhov no yog vim hais tias txawm hais tias hluavtaws fibers tsis biodegradable, tom qab raug cua thiab tshav ntuj los yog nquag ntxuav thiab txhuam, cov hluavtaws fibers yuav maj mam tawg mus rau hauv me me thiab me pieces kom txog thaum lawv tsis pom ntawm qhov muag liab qab thiab accumulates xav nrog cov ndlwg ntawm cov khoom. dej. Nws tshuab ib ncig ntawm cua-thiab ua rau ib puag ncig zoo rau txhua lub sijhawm.
Microscope saib lub kaum sab xis
Cov plaub hau VS microfibers Ntau ntawm cov hluavtaws fibers no tsis tshua muaj zog, hu ua microfibers. Ib lub microfiber yog nyias dua li ib txoj hlua ntawm cov kab lo lo ntxhuav, txog ib feem tsib ntawm txoj kab uas hla ntawm tib neeg cov plaub hau.
Nws tuaj yeem hais tias cov fibers hluavtaws yog qhov chaw ntawm microplastics feem ntau nyob rau hauv ib puag ncig niaj hnub no, tab sis los ntawm kev siv cov fibers ntuj los tshawb nrhiav thiab tsim cov hluavtaws fibers, nws yog crystallization ntawm tib neeg kev txawj ntse thiab kev tsim kho technology. Microfiber pollution tsis tau xav txog thiab xav tau. Ntau dua li tsis lees txais cov fibers hluavtaws kiag li, nws yog qhov zoo dua los nrhiav txoj hauv kev rau kev tshawb fawb thiab rationally tswj cov shedding thiab emission ntawm microfibers.
HOHENSTEIN Quantitative Analysis ntawm Microfibers
Thawj kauj ruam hauv kev daws cov teeb meem microfiber yog ua kom paub txog.
Raws li ib tus neeg siv khoom, koj tuaj yeem pib los ntawm kev nkag siab txog microfibers thiab siv kev tiv thaiv kev tiv thaiv; Raws li kev lag luam textile, koj yuav tsum tsis tu ncua optimize ntau lawm technology los txo cov tiam ntawm microfibers. Cov pa phem Microfiber tab tom ua rau thoob ntiaj teb saib xyuas cov khaub ncaws hluavtaws uas tsim los ntawm ntau lub khw muag khoom thiab cov khw muag khoom, thiab Hohenstein xav koom tes nrog koj los coj txoj hauv kev hauv txoj kev loj hlob no.
