E hatisitsoe hape ho tsoa ho: Setsi sa Lintho Tse Hlahisoeng ke Bophelo

Institute of Biodegradable Materials e tlaleha hore morao tjena, kotsi ea microplastic e se e lebisitsoe butle-butle, 'me lithuto tse amanang le tsona li hlahile ka mor'a tse ling, tse fumanoeng maling a motho, mantle le botebo ba leoatle.Leha ho le joalo, phuputsong ea morao tjena e phethiloeng ke Hull York Medical College, United Kingdom, bafuputsi ba fumane microplastics botebong ba matšoafo a batho ba phelang ka lekhetlo la pele.

Boithuto bona, bo hatisitsoeng koranteng ea General Environmental Science, ke thuto ea pele e matla ea ho tsebahatsa lipolasetiki tse matšoafong a batho ba phelang.

"Li-microplastics li fumanoe ka lisampole tsa motho ea ikemetseng pele - empa ena ke ea pele ea thuto e matla e bontšang li-microplastics matšoafong a batho ba phelang," ho boletse Dr. Laura Sadofsky, Setsebi se Seholo sa Meriana ea Phefumoloho le mongoli ea ka sehloohong oa pampiri., “Mekhoa ea moea matšoafong e tšesaane haholo, kahoo ha ho motho ea neng a nahana hore mohlomong a ka fihla moo, empa ho hlakile hore e ile ea fihla.

Lefatše le hlahisa lithane tse ka bang limilione tse 300 tsa polasetiki selemo se seng le se seng, hoo e ka bang 80% ea eona e qetellang e le litsing tsa lithōle le libakeng tse ling tsa tikoloho.Microplastic e ka fapana ka bophara ho tloha ho li-nanometer tse 10 (tse nyenyane ho feta kamoo leihlo la motho le ka li bonang) ho ea ho limilimithara tse 5, tse ka bang boholo ba raba qetellong ea pentšele.Likaroloana tse nyane li ka phaphamala moeeng, metsing a pompo kapa a libotlolo, le leoatleng kapa mobung.

Liphetho tse ling tsa lipatlisiso tsa nakong e fetileng mabapi le microplastics:

Phuputso ea 2018 e fumane polasetiki ka lisampole tsa setulo ka mor'a hore barupeluoa ba fepehe lijo tse tloaelehileng tse phuthetsoeng ka polasetiki.

Pampiri ea 2020 e ile ea hlahloba lisele tse tsoang matšoafong, sebete, spleen le liphio 'me ea fumana polasetiki lisampoleng tsohle tse ithutoang.

Lipatlisiso tse hatisitsoeng ka Hlakubele li fumane likaroloana tsa polasetiki maling a motho ka lekhetlo la pele.

Phuputso e ncha e sa tsoa etsoa ke barutehi Univesithing ea Bongaka ea Vienna e bontšitse hore ho noa metsi a libotlolo tsa polasetiki selemo ho pota ho ka fella ka ho kenngoa ha likaroloana tse ka bang 100,000 tsa microplastic le nanoplastic (MNP) ka motho ka selemo.

Boithuto ba hajoale, leha ho le joalo, bo ne bo batla ho ikahela mosebetsing o fetileng ka ho fumana li-microplastics ka har'a lisele tsa matšoafo ka ho kotula lisele nakong ea opereishene ho bakuli ba phelang.

Tlhahlobo e senotse hore lisampole tse 11 ho tse 13 tse ithutoang li ne li na le li-microplastic mme li fumane mefuta e 12 e fapaneng.Li-microplastics tsena li kenyelletsa polyethylene, nylon le li-resin tse atisang ho fumanoa ka libotlolong, liphutheloana, liaparo le line.thapo le mekhoa e meng ea tlhahiso.

Lisampole tsa banna li ne li e-na le litekanyetso tse phahameng haholo tsa li-microplastic ho feta tsa basali.Empa se ileng sa makatsa bo-rasaense haholo ke moo lipolasetiki tsena li neng li hlaha teng, tse nang le karolo e fetang halofo ea li-microplastic tse fumanehang likarolong tse ka tlaase tsa matšoafo.

"Re ne re sa lebella ho fumana palo e phahameng ea likaroloana tsa microplastic libakeng tse tebileng tsa matšoafo, kapa ho fumana likaroloana tsa boholo bona," ho boletse Sadofsky.Ho ne ho nahanoa hore likaroloana tsa boholo bona li ne li tla tlhotloa kapa li qabeletsoe pele li teba hakaalo.”

Bo-rasaense ba nka hore likaroloana tsa polasetiki tse tsamaisoang ke moea ho tloha ho nanometer e le 1 ho isa ho li-micron tse 20 li ka hema, 'me thuto ena e fana ka bopaki bo bongata ba hore ho hema ho ba fa tsela e tobileng' meleng.Joalo ka liphuputso tsa morao-rao tse tšoanang tšimong, e hlahisa potso ea bohlokoa haholo: Litlamorao ke life bophelong ba motho?

Liteko tse entsoeng ke bo-ramahlale ka laboratoring li bonts'itse hore li-microplastics li ka ikarola le ho fetola sebopeho sa lisele tsa matšoafo a motho, 'me li na le chefo e akaretsang liseleng.Empa kutloisiso ena e ncha e tla thusa ho tataisa lipatlisiso tse tebileng mabapi le litlamorao tsa eona.

"Li-microplastics li fumanoe ka lisampole tsa motho ea ikemetseng pele - ena ke thuto ea pele e matla ea ho bontša hore ho na le li-microplastics matšoafong a batho ba phelang," ho boletse Sadofsky.“E boetse e bontša hore li karolong e ka tlaase ea matšoafo.Litsela tsa moea tsa matšoafo li ngata haholo E moqotetsane, kahoo ha ho motho ea neng a nahana hore a ka fihla moo, empa ka ho hlaka ba fihlile moo.Sebopeho sa mefuta le maemo a li-microplastics tseo re li fumaneng joale li ka tsebahatsa maemo a nnete a lefats'e bakeng sa liteko tsa ho pepeseha laboratoring ka sepheo sa ho fumana litlamorao tsa bophelo bo botle. ”

"Ke bopaki ba hore re na le polasetiki 'meleng ea rona - ha rea ​​​​lokela ho ba le eona," Dick Vethaak, setsebi sa tikoloho ea Vrije Universiteit Amsterdam, o bolelletse AFP.

Ho feta moo, phuputso e hlokometse "ho ameha ho eketsehileng" mabapi le likotsi tse ka 'nang tsa e-ba teng tsa ho noa le ho hema microplastics.
