I nā makahiki i hala iho nei, ke ulu nei ka hopohopo e pili ana i ka laha ʻana o nā microplastics. Aia i loko o ke kai, i loko o nā holoholona a me nā mea kanu, a i loko o ka ʻōmole wai a mākou e inu ai i kēlā me kēia lā.
ʻIke ʻia nā microplastics ma nā wahi āpau. A ʻo ka mea ʻoi aku ka maikaʻi ʻole, ʻaʻole ia wale nō ma nā wahi āpau a puni mākou, akā me ka manaʻo ʻole i loko o ke kino kanaka.
Wahi a nā mea noiʻi ma ke Kulanui o New Mexico, ʻo nā microplastics mai ka wai a me ka meaʻai a mākou e ʻai ai, a me ka ea a mākou e hanu ai, e hele mai ko mākou ʻōpū i nā wahi ʻē aʻe o ke kino, e like me nā puʻupaʻa, ate a me ka lolo. .
No ka hiki ʻana i kēia hopena hou, hāʻawi ka poʻe ʻepekema i ka wai ʻiole me ka nui o nā microplastics i manaʻo ʻia e ʻai nā kānaka i kēlā me kēia pule. Ua hōʻike ʻia nā haʻawina mua e komo i loko o ke kino o ke kanaka he ʻelima grams microplastic i kēlā me kēia pule, ʻo ia ke kaumaha o ke kāleka hōʻaiʻē.
Wahi a Eliseo Castillo, ke kaukaʻi o ka gastroenterology a me ka hepatology ma ke Kulanui o New Mexico School of Medicine, ʻo ka ʻike ʻana e hana ana nā microplastics i ko lākou ala mai ka ʻōpū i nā ʻiʻo ʻē aʻe o ke kino kanaka. Wahi a ia, hoʻololi ia i nā cell immune, i kapa ʻia ʻo macrophages, a hiki i kēia ke alakaʻi i ka mumū i loko o ke kino.
Eia hou, ma kahi noiʻi ʻē aʻe, e nānā ʻo Kauka Castillo i ke ʻano o ka ʻai ʻana o ke kanaka i ke ʻano o ka lawe ʻana o nā microplastics e ke kino.
Na ia a me kāna hui e hoʻokau i nā holoholona lab i nā meaʻai like ʻole, me ka momona momona a me ka fiber kiʻekiʻe. ʻO nā ʻāpana microplastic e lilo i ʻāpana o ka "menu" o kekahi o nā holoholona, a ʻo nā mea ʻē aʻe ʻaʻole.
Wahi a kahi noiʻi i paʻi ʻia ma ka puke pai Environmental Pollution, akā naʻe, me ka nānā ʻole i ke ʻano o ka meaʻai a mākou e ʻai ai, ʻaʻohe microplastics e pakele ai. Ua ʻike nā kānaka ʻepekema ʻo 90% o nā protein, me nā mea ʻē aʻe vegan, loaʻa nā microplastics, i hoʻopili ʻia me ka maikaʻi ʻole. ola nā hopena.
Hiki ke kōkua i nā plastic biodegradable?
ʻO ka backlash e kūʻē i nā plastics hoʻohana hoʻokahi ua ʻike i nā hui he nui e ʻimi nei e hoʻohana i nā mea ʻē aʻe e ʻōlelo nei he ʻoi aku ka biodegradable a i ʻole ka compostable. Akā i kekahi mau hihia, hiki i kēia mau mea ke hoʻohui i ka pilikia microplastic. Ua ʻike ʻia ka noiʻi ʻana e nā ʻepekema ma ke Kulanui o Plymouth ma UK e hiki i nā ʻeke i kapa ʻia ʻo "biodegradable" hiki ke hoʻopau i nā makahiki he nui, a laila ʻoi aku ka nui o ka haki ʻana i nā ʻāpana liʻiliʻi ma mua o ko lākou mau ʻāpana kemika. (E aʻo hou e pili ana i ke kumu e hoʻopau ʻole ai nā biodegradables i ka pilikia palaki ma kēia ʻatikala na Kelly Oakes.)
Pehea e hoʻololi ai i nā ʻōmole aniani?
ʻO ka hoʻololi ʻana i ka ʻeke plastik hiki ke kōkua i ka hōʻemi ʻana i ka ʻike - He haʻahaʻa haʻahaʻa nā microplastics i ka wai paila ma mua o ka wai mai nā ʻōmole plastik. Akā, loaʻa nō hoʻi i nā hopena kaiapuni. ʻOiai He kiʻekiʻe ka hana hou ʻana o nā ʻōmole aniani, ia lakou kekahi kahi kapuaʻi kaiapuni ʻoi aku ka kiʻekiʻe ma mua o ka plastic a me nā ʻeke ʻē aʻe i hoʻohana ʻia no ka wai e like me nā pahu inu a me nā kini alumini. ʻO kēia no ka mea hiki ke hoʻopōʻino nui i ke kaiapuni i ka ʻeli ʻana o ka silica, kahi aniani i hana ʻia. ʻo ia hoʻi ka pōʻino o ka ʻāina a me ka nalowale o nā mea olaola. ʻOiai me kēia mau ʻeke palaki ʻole, paʻakikī ke pakele i nā microplastics holoʻokoʻa. Ua ʻike nā haʻawina i alakaʻi ʻia e Sherri Mason ma Pennsylvania State University ʻaʻole lākou wale nō i loko wai i ka wai, kahi e loaʻa mai ai ka hapa nui o ka palaka mai nā lole lole, akā pū kekahi ka paʻakai kai a me ka pia. E heluhelu hou aʻe e pili ana inā ʻoi aku ka maikaʻi o ke aniani a i ʻole ka plastic no ke kaiapuni.
Hiki ke hana i kekahi mea e hōʻemi i ka microplastics?
ʻO ka mea pōmaikaʻi, aia kekahi manaʻolana. Ke hoʻomohala nei nā mea noiʻi i kekahi mau ala e kōkua ai i ka hoʻopau ʻana i ka pollution plastic i ko mākou kaiapuni. ʻO kekahi ala ʻo ka huli ʻana i nā haʻiki a me nā hua bacteria e hānai ana i ka plastic, e wāwahi ana i ka hana. Ua hāʻawi pū kekahi ʻano o nā larvae pipi hiki ke ʻai i ka polystyrene. Ke nānā nei nā poʻe ʻē aʻe i ka hoʻohana ʻana i nā ʻenehana kānana wai a i ʻole nā hana kemika e hiki ke wehe i nā microplastics.
