Ungcoliseko lolwandle
Ungcoliseko lwaselwandle ngumbandela obaluleke kakhulu kwihlabathi lanamhlanje. Njengentliziyo yomhlaba, ulwandle luthatha malunga nama-75% ommandla womhlaba. Kodwa xa kuthelekiswa nenkunkuma yomhlaba, inkunkuma yaselwandle ayinanzwa lula. Ngenjongo yokutsalela ingqalelo yabantu kubume bemeko yomhlaba, i-Australian International Environmental Protection Organisation iye yasungula inkqubo yentlalontle yamazwe ngamazwe-iWorld Cleanup Day, ebanjwa ngeveki yesithathu kaSeptemba rhoqo ngonyaka, ngenjongo yokujongana nomhlaba wehlabathi ongalawulekiyo. ngokuchaphazela utshintsho kwiipatheni zokuziphatha kwabantu. Ingxaki yenkunkuma kunye nenkunkuma yaselwandle
Nika ingqalelo kungcoliseko lwe-microfiber
Kwinkunkuma yaselwandle, ungcoliseko lweplastiki lufikelela kuma-85%, kwaye ezi plastiki ziboliswa zibe ngamasuntswana amancinane ngamaza nokukhanya kwelanga ekuhambeni kweminyaka kwaye zikhona elwandle ixesha elide. Ukuqokelelana kwee-microfibers kwikhonkco lokutya kubangela ingozi enkulu kubo bonke ubomi baselwandle, kwaye ukukhutshwa kwazo kuhambelana ngokusondeleyo kubomi bethu bemihla ngemihla.
Microplastics egazini lomntu
Uphononongo lubonisa i-microplastics egazini lomntu
NgoMatshi, uphando olupapashwe kwiphephancwadi i-Environmental International lwatyhila okokuqala ukuba igazi lomntu liqulethe i-microplastics.
Abaphandi baseNetherlands baye baphuhlisa uvavanyo oluyintsha lokukhangela amasuntswana e-microplastic anokuthi afunxeke kwiinwebu emzimbeni womntu, kwaye bafumanisa ukuba i-17 yamavolontiya amadala angama-22 asempilweni, okanye i-77%, ine-microplastics egazini labo. I-microplastic eqhelekileyo kwezi sampuli zegazi yayiyi-polyethylene terephthalate (PET), esetyenziswa ngokubanzi kwiingubo kunye nokutya kunye nezitya zokusela, ilandelwa yi-polymeric styrene (PS), i-polyethylene (PE)) kunye ne-polymethyl methacrylate (PMMA).
Abaphandi kwiZiko leSizwe le-Oceanography yase-UK banenkxalabo ngenxa yokuba iincinci ze-microplastic zolu bukhulu zibonakaliswe kwibhubhoratri ukuze kubangele ukuvuvukala kunye nomonakalo weselula phantsi kweemeko zovavanyo. Igazi sele liphelile kwikhonkco le-microplastics. Esikhundleni sokufumana i-microplastics ekupheleni kunye nokunika izilumkiso, kungcono ukuzilawula ukusuka kumthombo. Enye yee-microplastics esondele kakhulu kubomi bemihla ngemihla babantu zii-microfibers ezivela kwilaphu.
Ungcoliseko lweMicroplastic
I-Microplastics ichaphazela kakubi abantu kunye nendalo kuzo zonke iinkalo
Ngo-2022, ingxelo yefashoni ezinzileyo yafumanisa ukuba amalaphu akhupha iitoni ezingama-200,000 ukuya kuma-500,000 ee-synthetic fibers kwimo engqongileyo yaselwandle kwihlabathi liphela, ezenza zibe ngowona mthombo mkhulu wongcoliseko lweplastiki elwandle.
Ngokwembono yokusingqongileyo elwandle, kuye kwavela iingxaki ezahlukeneyo zokusingqongileyo kwiminyaka yakutshanje, kubandakanywa ungcoliseko lweplastiki kunye ne-microfiber, ukuloba elwandle olunzulu, ukutshatyalaliswa kwemekobume yendalo, kunye namandla avuselelekayo elwandle. Phakathi kwezi ngxaki, ungcoliseko lwe-microfiber yenye yezona ngxaki zinzima, kwaye iziphumo ezahlukeneyo zophando ziyaqhubeka nokufumanisa kunye nobungqina bempembelelo engalunganga ye-microfibers kwizinto eziphilayo kunye nokusingqongileyo.
I-2.9% yombungu weentlanzi kunye ne-microbes zamanzi zingenisa kwaye zigcina i-microplastics kunye ne-microfibers engagayekiyo.
Kukho malunga nama-29 ukuya kuma-280 amaqhekeza e-microplastics, ngokukodwa i-microfibers, kwi-square meter yothuli lwe-atmospheric kunye nomoya ngosuku.
Amashumi amathathu anesihlanu epesenti yongcoliseko lwe-microplastic luvela ekuhlanjweni kwamalaphu enziweyo, kunye nezinto ezikhutshwayo zokuvasa ezilingana nokulahla amasuntswana eplastiki angama-50 eebhiliyoni elwandle ngonyaka ngamnye.
Uphononongo lufumene i-microplastics kwindle yabantu kunye negazi, ebonisa ukuba i-microplastics inokuhamba egazini, inkqubo ye-lymphatic kunye nesibindi, kwaye uphando olutsha lufumene ukuqokelela kwe-microfibrils kwimiphunga yabantu abaphilayo.
Iintsinga zokwenziwa ezifana ne-polyester, inayiloni, i-acrylic kunye nezinye izinto zihlala zisetyenziselwa ukwenza iimveliso zamalaphu ezahlukeneyo ngenxa yokuthamba kwazo okuhle, ukunyanzeliswa kunye nokunganyangeki kwamanzi. Kodwa ngokwenene, i-polyester, i-nylon, i-acrylic, njl. zonke iintlobo zeplastiki ezenziwe ngepetroleum okanye igesi yendalo. I-essential yabo ayihlukanga kwiingxowa zeplastiki, iibhotile zesiselo, njl., kwaye zonke aziyi-non-biodegradable pollutable.
IMicrofiber kunye neMicroplastic Lithetha ukuthini amalaphu alukiweyo angaboliyo?
Izingcolisi ezingaboliyo zibhekisa kwezo zingcolisi zingenako ukuguqulwa zibe zizinto ezingenabungozi kokusingqongileyo emva kokuthotywa kweekhemikhali, ukuthotywa kweekhemikhali kunye nokuthotywa kwebhayoloji kwindawo yendalo. Oko kukuthi, iingubo zendlela yoyilo efanayo, ezenziwe ngezinto zendalo zinokubumba ngokuthe ngcembe kwaye zibe yinxalenye yendalo emva kokushiywa ekoneni iminyaka eliqela, ngelixa ezo zenziwe ngezinto zokwenziwa zinokuba luthuli kunye neentanda - zinokuhamba kunye. Unexesha elide kakhulu, kangangokuba nangona uye wahlukana, uhlala ushiya umkhondo. Oku kungenxa yokuba nangona imicu yeplastiki eyenziweyo ingonakali, emva kokubethwa ngumoya nelanga okanye ukuhlanjwa rhoqo nokuhlikihlwa, iintsinga zokwenziwa ziya kuqhekeka ngokuthe ngcembe zibe ziziqwengana ezincinci nezincinci de zingabonakali ngeliso lenyama kwaye ziqokelelane ngokungathandekiyo amanzi. Uvuthuza ujikeleze umoya-kwaye ungcolisa okusingqongileyo ngalo lonke ixesha.
I-engile yokujonga nge-microscope
A iinwele VS microfibers Uninzi lwezi ntsinga zokwenziwa zibhide kakhulu, zibizwa ngokuba ziimicrofibers. I-microfiber incinci kunomcu wesilika, malunga nesinye kwisihlanu sobubanzi beenwele zomntu.
Kunokuthiwa iintsinga zokwenziwa zingumthombo weyona micu ye-microplastics kwimekobume yanamhlanje, kodwa ukusuka ekusebenziseni iintsinga zendalo ukuya kuphando kunye nokuphuhlisa imicu yokwenziwa, kukukhazimla kobulumko bomntu kunye nophuhliso lobuchwepheshe. Ungcoliseko lweMicrofiber alulindelwanga kwaye lulindelwe. Kunokuba ugatye ngokupheleleyo iintsinga zokwenziwa, kungcono ukufumana indlela yokulawula ngokwesayensi kunye nengqiqo ukuchithwa kunye nokukhutshwa kwee-microfibers.
HOHENSTEIN Uhlalutyo lobungakanani beMicrofibers
Inyathelo lokuqala lokujongana nengxaki ye-microfiber kukuphakamisa ulwazi.
Njengomthengi, ungaqala ngokuqonda i-microfibers kwaye uthathe amanyathelo okukhusela; njengeshishini lamalaphu, kufuneka uqhubeke ukhulisa itekhnoloji yokuvelisa ukunciphisa ukuveliswa kwee-microfibers. Ungcoliseko lwe-Microfiber lutsala ingqalelo yamazwe ngamazwe kwisixa sempahla yokwenziwa eveliswa ngabathengisi abaninzi kunye neempawu, kwaye uHohenstein angathanda ukudibanisa izandla kunye nawe ukukhokela indlela yolu phuhliso oluzinzileyo.
