ʻeke kī kī ʻole i ka plastik?ʻAe, ua lohe pololei ʻoe…

Mea hana ʻo Tonchant 100% pepa kānana manuahi ʻole no nā ʻeke kī,E aʻo hou ma ʻaneʻi

Loaʻa paha i kāu kīʻaha kī he 11 biliona microplastic particle a ma muli o ke ʻano o ka ʻeke kī.

Wahi a kahi noiʻi Kanada ma ke Kulanui ʻo McGill, ʻo ka hoʻokuʻu ʻana i kahi ʻeke kīʻaha ma kahi mahana wela o 95 ° C e hoʻokuʻu ana ma kahi o 11.6 biliona microplastics - nā ʻāpana liʻiliʻi o ka plastik ma waena o 100 nanometers a me 5 millimeters ka nui - i loko o ke kīʻaha hoʻokahi.Ke hoʻohālikelike ʻia i ka paʻakai, no ka laʻana, i loaʻa pū kekahi i loko o ka plastic, ʻo kēlā me kēia kīʻaha he mau kaukani ka nui o ka nui o ka plastic, ma 16 micrograms no ke kīʻaha.

ʻO ka piʻi nui ʻana o ka micro- a me ka nano-sized plastics i ke kaiapuni a me ke kaulahao meaʻai ke ulu nei ka hopohopo.ʻOiai ke hāpai nei ka poʻe kūʻai noʻonoʻo i ka hōʻemi ʻana i nā plastics hoʻohana hoʻokahi, ke hana nei kekahi mau mea hana i ka ʻeke plastik hou e pani ai i ka hoʻohana ʻana i nā pepa kuʻuna, e like me nā ʻeke kīwī.ʻO ka pahuhopu o kēia noiʻi ʻana, ʻo ia ka ʻike inā hiki i nā ʻeke ʻeke plastik ke hoʻokuʻu i nā microplastics a/a i ʻole nanoplastics i ka wā o kahi kaʻina hana maʻamau.Hōʻike mākou i ka hoʻokuʻu ʻana i hoʻokahi ʻeke plastik i ka mahana wela (95 °C) e hoʻokuʻu ma kahi o 11.6 biliona microplastics a me 3.1 biliona nanoplastics i hoʻokahi kīʻaha o ka mea inu.Hoʻohālikelike ʻia ke ʻano o nā mea i hoʻokuʻu ʻia me nā ʻeke kī mua (nylon a me polyethylene terephthalate) me ka hoʻohana ʻana i ka Fourier-transform infrared spectroscopy (FTIR) a me X-ray photoelectron spectroscopy (XPS).ʻO nā kiʻekiʻe o nā ʻāpana nylon a me ka polyethylene terephthalate i hoʻokuʻu ʻia mai ka ʻeke kīʻaha he mau kauoha o ka nui ma mua o nā ukana plastik i hōʻike mua ʻia ma nā meaʻai ʻē aʻe.Hōʻike ka loiloi mua ʻana i nā mea ʻawaʻawa invertebrate ʻo ka ʻike ʻana i nā ʻāpana wale i hoʻokuʻu ʻia mai nā ʻeke kī i hoʻokumu ʻia i nā hopena pili i ka dosis a me ka hoʻomohala ʻana.
