Ua loaʻa kahi noiʻi o ʻelima mau ʻano o nā iʻa iʻa i loaʻa i kēlā me kēia hāpana hoʻāʻo i ka nui o ka lula.
Ua kūʻai nā kānaka noiʻi i nā ʻōtio, ʻōpae, heʻe, pāpaʻi a me sardine mai kahi mākeke ma Australia a kālailai iā lākou me ka hoʻohana ʻana i kahi hana hou i hiki ke hoʻomaopopo a ana i nā ʻano palima ʻelima.
ʻO ke aʻo ʻana i mālama ʻia e ke Kulanui o Exeter a me ke Kulanui o Kuʻelana ʻike ʻia ka heʻe, gram shrimp, shrimp, oysters, shrimp, a sardines he 0,04 mg, 0,07 mg, ʻoyster 0,1 mg, crab 0.3 mg a me 2.9 mg
ʻO Francesca Ribeiro, ke alakaʻi o ka QUEX Institute, ua ʻōlelo ʻo ia: "Ma ka noʻonoʻo ʻana i ka ʻai maʻamau, hiki i nā mea kūʻai i ka iʻa kai ke ʻai ma kahi o 0.7 mg o ka ea ke ʻai i nā ʻōpala a i ʻole nā heʻe, ʻoiai e ʻai ana ka sardine i nā mea hou aku. A i 30mg o ka ea. "Haumana PhD.
"No ka hoʻohālikelike ʻana, ʻo ke kaulike kaulike o kēlā me kēia palaoa laiki 30 mg.
"Hōʻike kā mākou ʻike i ka nui o ka ea i loaʻa ma waena o nā ʻano ʻokoʻa ʻokoʻa loa, a aia nā ʻokoʻa ma waena o nā kānaka o ka ʻano like.
"Mai nā ʻano o nā iʻa i hoʻāʻo ʻia, ʻo ka sardine ka mea kiʻekiʻe loa o ka plastic, a he hopena kahaha ia."
ʻO Professor Tamara Galloway, kahi mea kākau o ka Exeter Institute for Global Systems, i ʻōlelo: "ʻAʻole maopopo iā mākou ka makaʻu o ke komo ʻana i nā lula i ke olakino kanaka, akā ʻo kēia ala hou e maʻalahi ai iā mākou e ʻike."
Ua kūʻai ka poʻe noiʻi i nā iʻa iʻa maka-ʻelima mau pāpaʻi uliuli hihiu, ʻumi ʻōtio, he ʻumi mau pua ʻai tiger i mahi ʻia, he ʻumi heʻe hihi, a he ʻumi sardine.
A laila, ua kālailai ʻia he ʻelima mau lula i hiki ke ʻike ʻia e ka hana hou.
Hoʻohana pinepine ʻia kēia mau lula a pau i ka wahī ʻūlū a me nā lole synthetic, a ʻike pinepine ʻia i nā ʻōpala kai: polystyrene, polyethylene, polyvinyl chloride, polypropylene a me polymethylmethacrylate.
I ke ʻano hou, mālama ʻia nā mea ʻai me nā kemikolo e hoʻonā i ka plastic i loko o ka hāpana. Nānā ʻia ka hopena hopena me ka hoʻohana ʻana i kahi ʻenehana koʻikoʻi nui i kapa ʻia pyrolysis gas chromatography-mass spectrometry, hiki ke ʻike like i nā ʻano plastics i ka laʻana.
Ua loaʻa ʻo Polyvinyl chloride i loko o nā laʻana a pau, a ʻo ka plastic me ke kiʻekiʻe kiʻekiʻe ʻo polyethylene.
ʻO nā microplastics he mau ʻāpana palapū liʻiliʻi e hoʻohaumia i nā hapa nui o ka honua, e like me ke kai. ʻAi lākou i nā ʻano nohona kai āpau, mai nā larva liʻiliʻi a me ka plankton a i nā māmela nui.
Ua hōʻike ʻia kahi noiʻi i kēia manawa ʻaʻole hiki i nā microplastics ke komo wale i kā mākou papaʻai mai nā iʻa o ke kai, akā komo pū i ke kino o ke kanaka mai ka wai ʻōmole, ka paʻakai kai, ka pia a me ka meli, a me ka lepo o ka meaʻai.
ʻO kahi hana hoʻāʻo hou kahi ʻanuʻu i ka wehewehe ʻana i ka nui o nā kaha lula i manaʻo ʻia he mea hōʻino a me ka loiloi ʻana i nā makaʻi o ka lawe ʻana i ka nui o ka plastic i ka meaʻai.
