Kuipitsa nyanja
Kuipitsa m’madzi ndi nkhani yofunika kwambiri masiku ano.Monga mtima wa dziko lapansi, nyanja imatenga pafupifupi 75% ya dziko lapansi.Koma poyerekezera ndi zinyalala zapamtunda, zinyalala za m’madzi zimanyalanyazidwa mosavuta.Pofuna kukopa chidwi cha anthu ku chilengedwe cha dziko lapansi, bungwe la Australian International Environmental Protection Organization lakhazikitsa zochitika zapadziko lonse lapansi - World Cleanup Day, yomwe imachitika kumapeto kwa sabata lachitatu la September chaka chilichonse, pofuna kuthana ndi dziko lonse lapansi. pokhudza kusintha kwa makhalidwe a anthu.Vuto la zinyalala ndi zinyalala za m’madzi
Samalani ndi kuipitsidwa kwa microfiber
M'zinyalala zam'madzi, kuipitsidwa kwa pulasitiki kumafikira 85%, ndipo mapulasitikiwa amawola tinthu ting'onoting'ono ndi mafunde ndi kuwala kwa dzuwa kwa zaka zambiri ndipo amakhala m'nyanja kwa nthawi yayitali.Kuchulukana kwa ma microfibers mumndandanda wazakudya kumawopseza kwambiri zamoyo zonse zam'madzi, ndipo utsi wawo umagwirizana kwambiri ndi moyo wathu watsiku ndi tsiku.
Microplastics m'magazi a anthu
Kafukufuku akuwonetsa ma microplastics m'magazi a anthu
M'mwezi wa Marichi, kafukufuku wofalitsidwa m'magazini yotchedwa Environment International adavumbulutsa kwa nthawi yoyamba kuti magazi a munthu amakhala ndi microplastics.
Ofufuza ku Netherlands apanga kuyesa kwatsopano kuti ayang'ane tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono ta thupi la munthu, ndipo adapeza kuti 17 mwa anthu 22 odzipereka athanzi, kapena 77%, anali ndi ma microplastics m'magazi awo.Microplastic yodziwika kwambiri m'miyeso yamagaziyi inali polyethylene terephthalate (PET), yomwe imagwiritsidwa ntchito kwambiri muzovala ndi zakudya ndi zakumwa, ndikutsatiridwa ndi polymeric styrene (PS), polyethylene (PE)) ndi polymethyl methacrylate (PMMA).
Ofufuza ku UK's National Oceanography Center ali ndi nkhawa chifukwa tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tambiri tawonetsedwa mu labotale toyambitsa kutupa ndi kuwonongeka kwa ma cell poyeserera.Magazi ali kale kutha kwa unyolo wa microplastics.M'malo mopeza ma microplastic kumapeto ndi kupereka machenjezo, ndi bwino kuwalamulira kuchokera ku gwero.Chimodzi mwazinthu zazing'ono zomwe zimagwirizana kwambiri ndi moyo wa tsiku ndi tsiku wa anthu ndi ma microfibers ochokera ku nsalu.
Kuwonongeka kwa Microplastic
Microplastics imakhudza anthu ndi chilengedwe m'mbali zonse
Mu 2022, lipoti la mafashoni okhazikika lidapeza kuti nsalu zidatulutsa matani 200,000 mpaka 500,000 a ulusi wopangira m'madzi padziko lonse lapansi, zomwe zimawapangitsa kukhala gwero lalikulu la kuyipitsa kwa pulasitiki m'nyanja.
Malinga ndi chilengedwe cha m'nyanja, m'zaka zaposachedwa pakhala mavuto osiyanasiyana a chilengedwe, kuphatikizapo kuipitsidwa kwa pulasitiki ndi microfiber, usodzi wa m'nyanja yakuya, kuwonongeka kwa chilengedwe, ndi mphamvu zongowonjezereka za m'nyanja.Pakati pa mavutowa, kuipitsidwa kwa microfiber ndi chimodzi mwazovuta kwambiri, ndipo zotsatira zafukufuku zosiyanasiyana zikupitirizabe kupeza ndi kutsimikizira zotsatira zoipa za microfiber pa zamoyo ndi chilengedwe.
2.9% ya mphutsi za nsomba ndi tizilombo tating'onoting'ono ta m'madzi timadya ndikusunga ma microplastics ndi microfibers osagawanika.
Palinso pafupifupi 29 mpaka 280 tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono, pa sikweya mita ya fumbi ndi mpweya wa mumlengalenga patsiku.
Makumi atatu ndi asanu peresenti ya kuwonongeka kwa microplastic kumachokera ku kutsuka nsalu zopangira, zomwe zimatsuka mpweya wofanana ndi kutaya mapulasitiki 50 biliyoni m'nyanja chaka chilichonse.
Kafukufuku wapeza ma microplastics mu ndowe ndi magazi a anthu, zomwe zimasonyeza kuti ma microplastics amatha kuyenda m'magazi, lymphatic system komanso chiwindi, ndipo kafukufuku watsopano wapeza kudzikundikira kwa microfibrils m'mapapu a anthu amoyo.
Ulusi wopangidwa monga poliyesitala, nayiloni, acrylic ndi zinthu zina nthawi zambiri amagwiritsidwa ntchito popanga nsalu zosiyanasiyana chifukwa cha kufewa kwawo, kuyamwa, komanso kukana madzi.Koma kwenikweni, polyester, nayiloni, acrylic, etc. ndi mitundu yonse ya mapulasitiki opangidwa ndi mafuta kapena gasi.Zomwe zimapangidwira sizosiyana ndi matumba apulasitiki, mabotolo a zakumwa, ndi zina zotero, ndipo zonsezi ndi zowonongeka zomwe sizingawonongeke.
Microfiber & Microplastic Kodi nsalu zansalu zosawonongeka zimatanthauza chiyani?
Zowononga zosawonongeka ndi biodegradable zimatanthawuza zoipitsa zomwe sizingasinthidwe kukhala zosavulaza zachilengedwe pambuyo pakuwonongeka kwa mankhwala, kuwonongeka kwa photochemical ndi kuwonongeka kwachilengedwe m'chilengedwe.Izi zikutanthauza kuti, nsalu zamtundu womwewo, zopangidwa ndi zinthu zachilengedwe zimatha kuumba pang'onopang'ono ndikukhala gawo la chilengedwe pambuyo posiyidwa pakona kwa zaka zingapo, pomwe zopangidwa ndi zida zopangira zimatha kukhala fumbi ndi ming'alu - zimatha kutsagana. Mwakhala nthawi yayitali, kotero kuti ngakhale mwagawanika, mwasiya zotsalira.Zili choncho chifukwa ngakhale kuti ulusi wopangidwa ndi pulasitiki sukhoza kuwonongeka, pambuyo powomberedwa ndi mphepo ndi dzuwa kapena kuchapa ndi kupakidwa pafupipafupi, ulusi wopangidwawo umasweka pang’onopang’ono n’kukhala tizidutswa ting’onoting’ono mpaka tosaoneka ndi maso n’kudziunjikira mwachisawawa ndi kutuluka kwa madzi. madzi.Imaomba mozungulira ndi mphepo—ndipo imawononga chilengedwe nthawi zonse.
Mlingo wowonera microscope
Tsitsi VS ma microfiber Ambiri mwa ulusi wopangidwa ndi wowonda kwambiri, wotchedwa microfibers.Ulusi wa microfiber ndi wochepa thupi kuposa ulusi wa silika, pafupifupi gawo limodzi mwa magawo asanu m'mimba mwake mwa tsitsi la munthu.
Tinganene kuti ulusi wopangidwa ndi gwero la ma microplastics ambiri masiku ano, koma kuyambira kungogwiritsa ntchito ulusi wachilengedwe mpaka kufufuza ndi kupanga ulusi wopangidwa, ndiko kuwunikira kwa nzeru zaumunthu ndi chitukuko chaukadaulo.Kuwonongeka kwa Microfiber sikuyembekezeredwa komanso kuyembekezera.M'malo mokana kotheratu ulusi wopangidwa, ndi bwino kupeza njira yasayansi ndi mwanzeru kuwongolera kukhetsa ndi kutulutsa kwa microfibers.
HOHENSTEIN Quantitative Analysis of Microfibers
Gawo loyamba lothana ndi vuto la microfiber ndikudziwitsa anthu.
Monga wogula, mukhoza kuyamba ndi kumvetsa microfibers ndi kutenga njira zodzitetezera;monga bizinesi yopangira nsalu, muyenera kupitiliza kukhathamiritsa ukadaulo wopanga kuti muchepetse kupanga ma microfibers.Kuwonongeka kwa Microfiber kukukopa chidwi chapadziko lonse lapansi kuchuluka kwa zovala zopangidwa ndi ogulitsa ambiri ndi ma brand, ndipo Hohenstein akufuna kuti agwirizane nanu kuti atsogolere chitukuko chokhazikikachi.
