ʻO ka ʻikepili i loaʻa mai nā ʻano wai kai i hōʻiliʻili ʻia mai nā wahi like ʻole i ka hoʻokūkū holo moana 60,000km lōʻihi, ua hōʻike ka Ocean Race 2022-23 i nā ʻike hou e pili ana i ka hāʻawi ʻana, ka ʻike a me nā kumu o nā microplastics moana.
Ua ʻokoʻa ka nui o nā microplastics i hopu ʻia i loko o nā laʻana mai 0.03 millimeters a i 4.6 millimeters. Hiki ke nānā ʻia nā ʻāpana microplastic liʻiliʻi e like me ka 0.03 millimeters me nā ʻano hana hoʻomaʻemaʻe. ʻO ka hopena, he helu kiʻekiʻe o nā microplastics: ma ka awelika, ua ʻike ʻia he 4,789 i hoʻokahi mika cubic o ka wai.
Ua loaʻa ka manaʻo kiʻekiʻe loa (26,334) kokoke i ʻApelika Hema, a ukali ʻia e ka lihi o ka English Channel kokoke i Brest, Farani (17,184), a laila kekahi wahi kokoke i ʻApelika Hema (14,976) a ukali ʻia e ke Kai Balearic (14,970) a ma ke Kai ʻĀkau ma waho o Denemaka (14,457). No laila, ʻekolu o nā wahi wela nui ʻelima o ka honua no ka pollution microplastic moana aia ma ʻEulopa. ʻO ka hana kiʻekiʻe o ke kanaka ma nā wahi e hōʻike ana i ke kiʻekiʻe o ka microplastics i nā wai a puni ʻEulopa, Brazil a me ʻApelika Hema. Eia naʻe, ʻaʻole ʻike ʻia nā kumu ma hope o ka ʻike ʻia ʻana o ka ʻike kiʻekiʻe ma ka Moana Hema. ʻAʻole maopopo ka holo ʻana o nā microplastics i ka hema mai ka Moana Hema a i Antarctica.
Ua hoʻoholo pū ka haʻawina i ke ʻano o ka huahana plastik i puka mai ai nā microplastics. Ua ʻike ʻia, ma ka awelika, 71% o nā microplastics i loko o nā laʻana he microfibers, mai nā mea e like me ka polyester, i hoʻokuʻu ʻia i loko o ke kaiapuni mai nā mīkini holoi (ma o ka wai ʻino), nā mea maloʻo (i ka lewa), ka hoʻokahe pololei mai. ʻaʻahu, hoʻohaʻahaʻa ʻia o nā lole i hoʻoheheʻe ʻia i loko o ke kaiapuni a me nā mea lawaiʻa i hoʻolei ʻia.
He mea koʻikoʻi kēia haʻawina ʻoiai ua ana ʻo ia i nā ʻāpana microplastic liʻiliʻi, e like me ka liʻiliʻi me 0.03 millimeters, no ka manawa mua. Ua ʻike pū ʻia nā kumu kumu o nā ʻāpana microplastic i ke kai.
ʻIke ʻia nā microplastics ma nā ʻano mea kai, mai plankton a hiki i nā koholā. ʻO ka mea pōʻino, ʻike lākou i ko lākou ala i ke kanaka ma o ke kaulahao meaʻai.
