Uhlalutyo lwedatha efunyenwe kwiisampulu zamanzi olwandle eziqokelelwe kwiindawo ezahlukeneyo ngexesha lokhuphiswano lwe-60,000km ubude behlabathi jikelele, i-Ocean Race 2022-23 ibonise ulwazi olutsha malunga nokusasazwa, ukugxila kunye nemithombo ye-microplastics yolwandle.
I-Microplastics ebanjwe kwiisampuli zahluka ngobukhulu ukusuka kwi-0.03 millimeters ukuya kwi-4.6 millimeters. Amasuntswana e-Microplastic amancinci njenge-0.03 millimeters angaphononongwa ngeendlela eziphuculweyo. Ngenxa yoko, inani eliphezulu le-microplastics: ngokomyinge, i-4,789 nge-cubic meter yamanzi yafunyanwa.
Olona gxininiso luphezulu (26,334) lwafunyanwa kufutshane noMzantsi Afrika, lulandelwa ngumda weEnglish Channel kufuphi neBrest, eFransi (17,184), kwalandela enye indawo ekufutshane noMzantsi Afrika (14,976) kulandele uLwandle lweBalearic (14,970) kunye Ulwandle lwaseMntla eDenmark (14,457). Ke, iindawo ezintathu kwezona ndawo zintlanu ziphezulu emhlabeni zongcoliseko lweplastiki elwandle ziseYurophu. Imisebenzi yabantu ephezulu kwimimandla ibangela ukuxinana okuphezulu kwee-microplastics emanzini ajikeleze iYurophu, iBrazil kunye noMzantsi Afrika. Nangona kunjalo, izizathu ezibangela ukujongwa okuphezulu kuLwandlekazi oluMazantsi azaziwa. Akukacaci nokuba ii-microplastics zihambela emazantsi ukusuka kuLwandlekazi oluMazantsi ukuya e-Antarctica.
Uphononongo luphinde lwamisela uhlobo lwemveliso yeplastiki evela kwi-microplastics. Kufunyaniswe ukuba, ngokwe-avareji, i-71% ye-microplastics kwiisampulu yayiyi-microfibers, evela kwizinto ezifana ne-polyester, ezikhutshelwa kwimo engqongileyo ukusuka koomatshini bokuhlamba (ngokusebenzisa amanzi amdaka), i-dryer (emoyeni), ukuchithwa ngokuthe ngqo impahla, ukuthotywa kweempahla ezilukiweyo ezithe saa kokusingqongileyo kunye nezixhobo zokuloba ezilahliweyo.
Olu phononongo lubalulekile njengoko lulinganisa iincinci ezincinci ze-microplastic, ezincinci njenge-0.03 millimeters, okokuqala. Kwakhona ichonge imithombo yemvelaphi yamasuntswana e-microplastic elwandle.
I-microplastics ifunyenwe ngokubanzi kwiintlobo zaselwandle, ukusuka kwiplankton ukuya kwiminenga. Ngelishwa, bafumana indlela yabo ebantwini ngekhonkco lokutya.
