Kusvibiswa kwegungwa
Kusvibiswa kwegungwa inyaya inokosha zvikuru munyika yanhasi. Semwoyo wepasi, gungwa rinotora chikamu chinosvika makumi manomwe neshanu kubva muzana chenzvimbo yepasi. Asi zvichienzaniswa nemarara epasi, marara emugungwa anofuratirwa nyore nyore. Kuitira kuti vanhu vatarise nezvemhoteredzo yepasi, sangano reAustralian International Environmental Protection Organisation rakatanga chirongwa chezvekugarisana pasi rose - World Cleanup Day, icho chinoitwa mukupera kwesvondo rechitatu raGunyana gore rega rega, nechinangwa chekugadzirisa pasi rose. nekukanganisa kuchinja kwemaitiro evanhu.

Teerera kune microfiber kusvibiswa
Mumarara emugungwa, kusvibiswa kwepurasitiki kunosvika 85%, uye mapurasitiki aya anoparadzwa kuita zvidimbu zvidiki nemafungu uye nechiedza chezuva nekufamba kwemakore uye aripo mugungwa kwenguva yakareba. Iko kuunganidzwa kwemamicrofibers mucheni yekudya kunoisa njodzi yakakomba kuhupenyu hwese hwemugungwa, uye kuburitsa kwavo kwakabatana zvakanyanya nehupenyu hwedu hwezuva nezuva.
Microplastics muropa revanhu
Kudzidza kunoratidza microplastics muropa revanhu
Muna Kurume, ongororo yakabudiswa mumagazini inonzi Environment International yakaratidza kekutanga chokwadi chekuti ropa remunhu rine microplastics.
Vatsvagiri muNetherlands vakagadzira bvunzo nyowani yekutsvaga microplastic particles inogona kunyura mukati me membranes mumuviri wemunhu, uye vakawana kuti gumi nenomwe kubva makumi maviri nevaviri vane hutano vanozvipira, kana makumi manomwe nenomwe muzana, vaive nemamicroplastics muropa ravo. Iyo yakajairika microplastic mumasampuli eropa aya yaive polyethylene terephthalate (PET), iyo inoshandiswa zvakanyanya mumachira uye chikafu uye zvinwiwa midziyo, ichiteverwa nepolymeric styrene (PS), polyethylene (PE)) uye polymethyl methacrylate (PMMA).
Vatsvagiri veku UK's National Oceanography Center vane hanya nekuti zvidimbu zvidiki zvesaizi iyi zvakaratidzwa murabhoritari kukonzera kuzvimba uye kukuvadzwa kwemaseru pasi pemamiriro ekuyedzwa. Ropa ratova kuguma kweketani ye microplastics. Panzvimbo pekutsvaga microplastics kumagumo uye kupa yambiro, zviri nani kuvadzora kubva kunobva. Imwe yemamicroplastic ane hukama zvakanyanya nehupenyu hwevanhu hwezuva nezuva ndeye microfibers kubva kumachira.
Microplastic Kusvibiswa
Microplastics iri kukanganisa vanhu uye zvisikwa mune zvese zvikamu
Muna 2022, mushumo wefashoni yakagadzikana wakawana kuti machira akaburitsa mazana maviri ezviuru kusvika mazana mashanu ematani emafuta ekugadzira munzvimbo dzemugungwa pasi rose, zvichivaita sosi huru yekusvibiswa kwepurasitiki mugungwa.
Kubva pamaonero ezvakatipoteredza, matambudziko akasiyana-siyana ezvakatipoteredza akabuda mumakore achangopfuura, anosanganisira kusvibiswa kwepurasitiki uye microfiber, kuredza kwakadzika kwegungwa, kuparadza kwezvakatipoteredza, uye simba remugungwa rinovandudzwazve. Pakati pematambudziko aya, kusvibiswa kwemicrofiber nderimwe rematambudziko akakomba, uye mhedzisiro yekutsvagisa yakasiyana-siyana inoramba ichiwana uye kuratidza kuipa kwemicrofiber pane zvipenyu uye nharaunda.
2.9% yehove dzehove uye tupukanana dzemvura dzinodya uye dzinochengeta indigestible microplastics uye microfibers.
Kune zvakare anenge 29 kusvika 280 zvidimbu zvemicroplastics, kunyanya microfibers, paskweya mita yeguruva remuchadenga nemhepo pazuva.
Makumi matatu neshanu muzana ekusvibiswa kwemicroplastic kunobva mukuwacha machira ekugadzira, nekugezwa kwemhepo kwakaenzana nekukanda 50 bhiriyoni zvidimbu zvepurasitiki mugungwa gore rega rega.
Zvidzidzo zvakawana microplastics mutsvina yevanhu neropa, zvichiratidza kuti microplastics inogona kuyerera muropa, lymphatic system uye kunyange chiropa, uye tsvakurudzo itsva yakawana kuunganidzwa kwe microfibrils mumapapu evanhu vapenyu.
Synthetic fibers senge polyester, nylon, acrylic uye zvimwe zvinhu zvinowanzo shandiswa kugadzira zvigadzirwa zvemachira zvakasiyana nekuda kwekupfava kwavo kwakanaka, kunyura, uye kuramba mvura. Asi kutaura zvazviri, polyester, naironi, acrylic, nezvimwewo marudzi ese emapurasitiki akagadzirwa nepetroleum kana gasi rechisikigo. Hunhu hwavo hauna kusiyana nemabhegi epurasitiki, mabhodhoro ezvinwiwa, nezvimwewo, uye ese ari ezvisina-biodegradable zvinosvibisa.
Microfiber & Microplastic Ko machira asina-biodegradable textile anorevei?
Non-biodegradable pollutants zvinoreva izvo zvinosvibisa zvisingagoni kuchinjwa kuva zvinhu zvisingakuvadzi zvakatipoteredza mushure mekuparara kwemakemikari, photochemical degradation uye biological degradation munzvimbo yakasikwa. Izvi zvinoreva kuti, micheka yemhando imwechete yekugadzira, yakagadzirwa nemidziyo yechisikigo inogona kuumbwa zvishoma nezvishoma uye kuva chikamu chechisikwa mushure mekusiiwa mukona kwemakore akati wandei, nepo iyo yakagadzirwa nezvinhu zvekugadzira inogona kungova guruva uye kuputika - vanogona kuperekedza. Wave wakareba, wakareba zvekuti nyangwe wakaparara, wagara wakasiya maronda. Izvi zvinodaro nekuti kunyangwe mafibhi epurasitiki ekugadzira asingaparadzike, mushure mekusangana nemhepo nezuva kana kugezwa nguva nenguva nekukweshwa, mafibisi ekugadzira anotsemuka zvishoma nezvishoma kuita zvidimbu zvidiki uye zvidiki kusvika zvave zvisingaonekwe nemeso uye zvinoungana zvisingaite nekuyerera kwe. mvura. Inovhuvhuta ichitenderera nemhepo—uye inosvibisa zvakatipoteredza nguva dzose.
Maikorosikopu yekuona angle
Bvudzi VS microfibers Mazhinji eaya mafiber ekugadzira akatetepa zvakanyanya, anonzi mamicrofiber. A microfiber yakatetepa kupfuura shinda yesirika, chinenge chikamu chimwe muzvishanu chedhayamita yebvudzi remunhu.
Zvinogona kutaurwa kuti mafibhi ekugadzira ndiwo anokonzeresa mamicroplastics akawanda munharaunda yanhasi, asi kubva pakungoshandisa shinda dzechisikigo kusvika pakutsvaga nekugadzira mafibhi ekugadzira, ndiko kupenya kwehuchenjeri hwevanhu uye kusimukira kwetekinoroji. Microfiber kusvibiswa hakutarisirwi uye kunotarisirwa. Pane kuramba zvachose mafibhi ekugadzira, zviri nani kutsvaga nzira yesainzi uye zvine musoro kudzora kubuda uye kubuda kwemicrofibers.
