Tlhahlobo ea lintlha tse fumanoeng ho tsoa lisampong tsa metsi a leoatle tse bokelletsoeng libakeng tse fapaneng nakong ea tlholisano ea lefatše ka bophara ea 60,000km, Ocean Race 2022-23 e senotse lintlha tse ncha mabapi le kabo, mahloriso le mehloli ea li-microplastics tsa leoatleng.
Li-microplastics tse nkiloeng ka lisampole li fapane ka boholo ho tloha ho limilimithara tse 0.03 ho isa ho limilimithara tse 4.6. Likaroloana tsa Microplastic tse nyane joalo ka limilimithara tse 0.03 li ka hlahlojoa ka mekhoa e hloekisitsoeng. Ka lebaka leo, palo e phahameng ea li-microplastics: ka karolelano, 4,789 ka cubic meter ea metsi e ile ea sibolloa.
Palo e phahameng ka ho fetisisa (26,334) e fumanoe haufi le Afrika Boroa, e lateloa ke moeli oa English Channel haufi le Brest, Fora (17,184), joale ntlha e 'ngoe e haufi le Afrika Boroa (14,976) e lateloa ke Leoatle la Balearic (14,970) le Leoatle le ka Leboea la Denmark (14,457). Kahoo, libaka tse tharo ho tse hlano tse holimo ka ho fetisisa lefatšeng bakeng sa tšilafalo e nyenyane ea maoatleng li Europe. Ts'ebetso e phahameng ea batho literekeng e baka khatello e phahameng ea li-microplastic metsing a pota-potileng Europe, Brazil le Afrika Boroa. Leha ho le joalo, mabaka a entseng hore ho be le libaka tse phahameng tse bonoang Leoatleng le ka Boroa ha a tsejoe. Hape ha ho hlake hore na li-microplastics li ea ka boroa ho tloha Leoatleng le ka Boroa ho ea Antarctica.
Boithuto bo boetse bo fumane mofuta oa sehlahisoa sa polasetiki seo li-microplastics li simolohileng ho tsona. Ho fumanoe hore, ka karolelano, 71% ea li-microplastics tse ka lisampole e ne e le li-microfibers, tse tsoang linthong tse kang polyester, tse lokolloang tikolohong ho tloha mechine ea ho hlatsoa (ka metsi a litšila), li-dryer (moeeng), ho tšolloa ka ho toba liaparo, ho senyeha ha masela a qhalaneng tikolohong le lisebelisoa tse lahliloeng tsa ho tšoasa litlhapi.
Phuputso ena e bohlokoa kaha e ile ea lekanya likaroloana tse nyane tsa microplastic, tse nyane joalo ka limilimithara tse 0.03, khetlo la pele. E boetse e tsebahalitse mehloli ea tšimoloho ea likaroloana tsa microplastic ka leoatleng.
Li-microplastics li fumanoa ka bongata mefuteng ea leoatle, ho tloha ho plankton ho ea ho maruarua. Ka bomalimabe, ba boetse ba fumana tsela ea bona ho batho ka ketane ea lijo.
