ʻEke kī palakiko ʻole? ʻAe, ua lohe pololei ʻoe i kēlā…

Mea hana Tonchant 100% pepa kānana ʻole plastik no nā ʻeke kī,E AʻO HOU AʻE MAʻANEʻI

Aia paha i loko o kāu kīʻaha kī he 11 biliona mau ʻāpana microplastic a ʻo kēia ma muli o ke ʻano o ka hana ʻenekinia ʻana o ka ʻeke kī.

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

Ke hopohopo nui nei ka nui o nā plastics micro- a me nano-sized i ke kaiapuni a me ke kaulahao meaʻai. ʻOiai ke paipai nei nā mea kūʻai aku i ka hōʻemi ʻana i nā plastics hoʻohana hoʻokahi, ke hana nei kekahi mau mea hana i nā ʻōpala plastic hou e pani i nā hoʻohana pepa kuʻuna, e like me nā ʻeke kī plastic. ʻO ka pahuhopu o kēia noiʻi, ʻo ia ka hoʻoholo inā hiki i nā ʻeke kī plastic ke hoʻokuʻu i nā microplastics a/a i ʻole nā ​​nanoplastics i ka wā o ke kaʻina hana hoʻomoʻa maʻamau. Hōʻike mākou ʻo ka hoʻomoʻa ʻana i hoʻokahi ʻeke kī plastic ma ka mahana hoʻomoʻa (95 °C) e hoʻokuʻu i kahi 11.6 biliona microplastics a me 3.1 biliona nanoplastics i loko o hoʻokahi kīʻaha o ka mea inu. Hoʻohālikelike ʻia ka haku mele ʻana o nā ʻāpana i hoʻokuʻu ʻia me nā ʻeke kī kumu (nylon a me polyethylene terephthalate) me ka hoʻohana ʻana i ka Fourier-transform infrared spectroscopy (FTIR) a me X-ray photoelectron spectroscopy (XPS). ʻOi aku ka nui o nā pae o nā ʻāpana nylon a me polyethylene terephthalate i hoʻokuʻu ʻia mai ka ʻōpala ʻeke kī ma mua o nā ukana plastic i hōʻike mua ʻia i nā meaʻai ʻē aʻe. Ua hōʻike ʻia kahi loiloi mua o ka ʻawahia invertebrate ʻo ka ʻike ʻana i nā ʻāpana wale nō i hoʻokuʻu ʻia mai nā ʻeke kī i hoʻoulu ai i nā hopena pili i ka hana a me ka ulu ʻana.
