Bisphenol A: ma hea ia e peʻe nei?
ʻO nā ʻōmole plastik, nā loaʻa, nā ipu meaʻai, nā kini, nā mea pāʻani… Aia ʻo Bisphenol A ma nā wahi āpau a puni mākou. Ke manaʻo nei ka European Food Safety Authority e aʻo i nā hopena ʻona o kēia pūhui kemika, ʻaʻole e pau ke kamaʻilio ʻana no…
ʻO Bisphenol A kahi mole i hoʻohana ʻia i ka hana ʻana i nā resins plastik. Aia ma loko o kekahi mau kini, pahu mea'ai, a me nā ki'i. I ka makahiki 2008, ua pāpā ʻia no ka hana ʻana i nā hue pēpē ma Kanada, a laila ma Farani ʻelua makahiki ma hope. A laila, manaʻo ʻia ka loaʻa ʻana o nā hopena pōʻino i ke olakino, ʻoiai ma nā haʻahaʻa haʻahaʻa loa.
He mea hoʻopilikia endocrine
Hoʻomalu ʻia kekahi mau hana kino, e like me ka ulu ʻana a i ʻole ka ulu ʻana, e nā ʻelele kemika i kapa ʻia ʻo "hormones". Hoʻopili ʻia lākou e like me nā pono o ke kino, e hoʻololi i ke ʻano o kahi okana. Hoʻopaʻa kēlā me kēia hormone i kahi mea loaʻa kikoʻī, e like me kēlā me kēia kī pili i kahi laka. Eia nō naʻe, hoʻohālikelike nā molekala o Bisphenol A i kahi hormone maoli, a kūleʻa i ka hoʻopili ʻana iā lākou iho i kā lākou kelepona. He haʻahaʻa loa kāna hana ma mua o nā hormones maoli, akā no ka mea aia i loko o ko mākou kaiapuni (ma kahi o 3 miliona tonnes i hana ʻia i kēlā me kēia makahiki ma ka honua), ʻoiaʻiʻo ka hopena i ke kino.
Hoʻopiʻi ʻia ʻo Bisphenol A no ke komo ʻana i nā maʻi maʻi ʻaʻai, ka hoʻohua ʻana, ka maʻi diabetes a me ka momona. ʻO ka mea ʻoi aku ka koʻikoʻi, ʻo ia ke kuleana no nā pilikia koʻikoʻi o ka ʻōnaehana endocrine i nā pēpē, e hoʻoulu ai i ka wā ʻōpio mua i nā kaikamahine a me ka emi ʻana o ka momona o nā keikikāne.
ʻLelo aʻoaʻo kūpono
Loaʻa i ka Bisphenol A ke ʻano koʻikoʻi o ka hiki iā ia ke unuhi iā ia iho mai nā plastics me ka manawaleʻa e launa pū me ka meaʻai. Hoʻonui ʻia kēia waiwai i ka wela kiʻekiʻe. ʻO nā ʻōmole wai i ʻike ʻia i ka lā pololei, nā kini paʻa i ka ea i hoʻomehana ʻia i loko o ka microwave a i ʻole nā kini i loko o ka bain-marie: hoʻokuʻu nā mea a pau i nā ʻāpana liʻiliʻi e komo ʻia e nā mea ola.
No ka pale ʻana i kēia, e nānā wale i kāu mau ipu plastik. Hoʻopili mau ʻia ka hōʻailona "recycling" me kahi helu. Pono e pale ʻia nā helu 1 (loaʻa nā phthalates), 3 a me 6 (hiki ke hoʻokuʻu i ka styrene a me ka vinyl chloride) a me 7 (polycarbonate). E mālama i nā pahu wale nō me nā code penei: 2 a i ʻole HDPE, 4 a i ʻole LDPE, a me 5 a i ʻole PP (polypropylene). I nā hihia a pau, pono ʻoe e hōʻole i ka hoʻomehana ʻana i ka meaʻai i loko o nā pahu plastik: e makaʻala i nā ipu liʻiliʻi i loko o ka bain-marie a i ʻole ka microwave!
ʻOi aku ka liʻiliʻi o nā loaʻa me kēia ʻāpana. No ka ʻoiaʻiʻo, e nānā inā loaʻa nā huaʻōlelo "guaranteed bisphenol A manuahi" ma ke kua.
