Ua lilo nā microplastics i pilikia honua: aia lākou mai nā iʻa a i nā pūnaewele spider; ʻO ka makani kai a i ʻole nā piko o nā Pyrenees i loko o nā ʻāpana o kēia mea kūpaʻa, hiki ke lawe i 450 mau makahiki e hoʻohaʻahaʻa. A, ʻoiaʻiʻo, i loko o mākou iho: kahi noiʻi hou i paʻi ʻia ma 'Environment, Science and Technology' e hōʻike ana ma waena o 40.000 a me 50.000 microplastic particles i pau i kēlā me kēia makahiki.
ʻO ia ke kumu i ʻimi ʻia ai nā ʻano hoʻonā like ʻole e hoʻopau i kēia mau ʻenemi ʻike ʻole ʻia, ʻoi aku ka nui o nā mea āpau i loaʻa i ka wai. Aia nā lāʻau lapaʻau e hoʻopau iā lākou, akā i kēia manawa e lawe lākou i nā lā. I kēia manawa, ua hoʻohana kekahi hui i alakaʻi ʻia e nā mea noiʻi ma ke Kulanui ʻo RMIT ma Melbourne, Australia, i kahi ala ʻē aʻe i ʻoi aku ka wikiwiki a me ka emi o ke kumukūʻai, e hana ana i kahi puna o ka lepo magnetic e 'pāhele' i nā mea ʻino, me 1,000 mau ʻāpana liʻiliʻi ma mua o ka mea i ʻike ʻia e ka wai ʻino. mea kanu lapaau. Ua paʻi ʻia nā hopena ma ka 'Chemical Engineering Journal'.
"He lanakila nui kēia no ka ʻenehana media a me ka hoʻokele waiwai pōʻai," wahi a Nicky Eshtiaghi, ka mea kākau kumu o ka noiʻi. "ʻO ke ʻano nanopillar a mākou i hoʻolālā ai e wehe i kēia mea ʻino, ʻaʻole hiki ke hoʻoneʻe akā e pōʻino loa i ke kaiapuni, ua hana hou ʻia mai ka ʻōpala a hiki ke hoʻohana ʻia i nā manawa he nui," wahi a ka mea noiʻi ma kahi ʻōlelo.
Pehea e hana ai
Ma nā huaʻōlelo paʻa, ua hoʻomohala nā mea kākau i kahi ʻano e hoʻohana ana i nā nanomaterials i nehinei i loaʻa nā microplastics a me nā mea hoʻoheheʻe ʻia. Ua wehewehe ʻo Muhammad Haris, ka mea kākau mua a me ka haumāna PhD, mahalo i kāna mau ʻāpana ferrous, hiki ke hoʻohana ʻia nā magnet e hoʻokaʻawale maʻalahi i kēia mau microplastics mai ka wai. "Hoʻokahi hola kēia kaʻina holoʻokoʻa, ke hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe e hiki ke lawe i nā lā," wahi a Haris.
Ua hoʻohui ʻo Nasir Mahmood, kekahi o nā mea kākau, ua hoʻolālā ʻia ka mea e huki ai i nā microplastics me ka ʻole o ka hoʻokumu ʻana i nā pollutants lua a i ʻole ka hohonu ʻana i ka wāwae carbon. "Hoʻomākaukau ʻia ka sorbent i ke ʻano e hiki ai ke hoʻoneʻe maikaʻi ʻia mai ka wai i ka manawa like me ka microplastics."
ʻO nā microplastics ʻoi aku ka liʻiliʻi ma mua o 5 millimeters, hiki ke lawe i 450 mau makahiki e hoʻohaʻahaʻa ai, ʻaʻole hiki ke ʻike ʻia a hiki ʻole ke wehe ʻia ma o nā ʻōnaehana mālama maʻamau, e hopena i nā miliona o nā tona i hoʻokuʻu ʻia i ke kai i kēlā me kēia makahiki. "ʻAʻole kēia he mea pōʻino i ke ola wai, akā he hopena maikaʻi ʻole nō hoʻi i ke olakino kanaka," wahi a nā mea kākau.
ʻO kēia mau kaʻina hana
I kēia manawa ua loaʻa i ka hui kahi ala kūpono e hoʻokō ai i ka paʻakikī o nā microplastics i ka wai, ʻo ka hana aʻe e neʻe i ka hana ʻoihana. "Ke ʻimi nei mākou i nā hoa hana e hoʻokō i kā mākou mea i hana ʻia ma nā ʻanuʻu aʻe, kahi e ʻimi ai mākou i kāna noi i nā mea kanu hoʻomaʻemaʻe wai", hanana.
Ua hana ʻo Eshtiaghi a me kāna mau hoa hana me kekahi mau mea pono wai ma Australia, me ka Melbourne Water et Water Corporation ma Perth ma kahi papahana Liaison Australian Research Council no ka hoʻomaikaʻi ʻana i nā ʻōnaehana sludge pumping.
