Ua ʻike ʻia kahi noiʻi hou e kahi hui o nā mea noiʻi mai Kelemānia, Pelekane Nui a me Kanada e ulu ana nā algae e ulu ana ma lalo o ke kai hau ma ka Arctic "ua hoʻohaumia nui ʻia" me nā microplastics, e hoʻoweliweli ana i nā kānaka i ke kaulahao meaʻai, hōʻike UPI.
ʻO ka limu liʻiliʻi i kapa ʻia ʻo Melosira arctica he awelika o 31,000 microplastic particles per cubic meter, ma kahi o 10 mau manawa i ka ʻike ʻana i ka wai ambient, ʻike nā mea noiʻi, i ʻōlelo ʻia e BTA. Wahi a lākou, ʻo ka awelika ma kahi o 19,000, ʻo ia hoʻi, ua loaʻa paha i kekahi mau puʻupuʻu he 50,000 mau ʻāpana microplastic i ka mika cubic.
Ua hana ʻia ka noiʻi ma ka Helmholtz Center for Polar and Marine Research ma Alfred Wegener Institute, ma muli o nā laʻana i hōʻiliʻili ʻia i ka wā o kahi huakaʻi me ka moku noiʻi Polarstern ma 2021. Ua paʻi ʻia nā hopena o ka hana a ka hui honua ma ka Pōʻalima ma ka puke pai " Environmental Science and Technology ".
"He ʻano liʻiliʻi ko ka filament algae, no laila hiki iā lākou ke ʻohi i nā microplastics mai ka waiho ʻana o ka lewa ma ke kai, mai ka wai kai ponoʻī, mai ka hau a puni a mai nā kumu ʻē aʻe a lākou e hele ai," wahi a Deoni Allen o ke Kulanui o Canterbury. he hoʻokuʻu media. a me ke Kulanui o Birmingham, ʻo ia kekahi o ka hui noiʻi.
ʻO ka iʻa, e like me ka cod, hānai i nā algae a ʻai ʻia e nā holoholona ʻē aʻe, me ke kanaka, a laila e hoʻouna i kahi "ʻano plastics" me ka polyethylene, polyester, polypropylene, nylon a me ka acrylic, a laila e loaʻa i loko o nā kino kanaka.
"Ke hilinaʻi nui nei ka poʻe o ka Arctic i ka pūnaewele meaʻai moana no kā lākou lako protein, no ka laʻana ma o ka hahai holoholona a lawaiʻa paha," wahi a Melanie Bergman, ka mea nāna i alakaʻi i ka noiʻi. "ʻO ia hoʻi ke ʻike ʻia lākou i nā hopena o nā microplastics a me kāna mau kemika. "Ua loaʻa mua nā microplastics i loko o ka ʻōpū o ke kanaka, koko, veins, māmā, placenta a me ka waiū umauma a hiki ke hoʻoulu i nā hopena ʻeha, akā ʻaʻole i ʻike ʻia nā hopena holoʻokoʻa," wahi a Bergman.
ʻO nā puʻupuʻu o nā algae make pū kekahi e lawe wikiwiki i nā microplastics i ke kai hohonu, e wehewehe ana i ke kiʻekiʻe o nā microplastics i loko o ka sediment - kekahi ʻike nui o ka noiʻi hou. E ulu wikiwiki ana ka limu ma lalo o ka hau kai i ka mahina pūnāwai a me ke kauwela, a ma laila lākou e hana ai i nā kaulahao ka lōʻihi o ka mika i lilo i mau puʻupuʻu i ka wā e make ai nā pūnaewele. I loko o hoʻokahi lā, hiki iā lākou ke hoʻopaʻa i nā kaukani mika i lalo o ke kai hohonu. "Ua loaʻa iā mākou kahi wehewehe kūpono no ke kumu e ana mau ai mākou i nā microplastics kiʻekiʻe loa i nā sediments hohonu," wahi a Bergman. Ua ʻōlelo hou ʻo ia e hōʻike ana nā noiʻi ʻo ka hōʻemi ʻana i ka hana plastik ke ala maikaʻi loa e hōʻemi ai i kēia ʻano haumia.
"ʻO ia ke kumu he mea nui kēia i ka ʻaelike plastik honua e kūkākūkā ʻia nei," wahi a Bergman. E hele ʻo ia i ke kaʻina kūkākūkā e hiki mai ana e hoʻomohala i kahi kuʻikahi UN e hōʻemi i ka pollution plastic. Hoʻomaka ʻia nā kamaʻilio ma Paris i ka hopena o Mei.
