• Nā ʻano ea
• Pakele paha i ka ea ea?
• Nā ala ʻē aʻe e hōʻemi ai i kou hōʻike ʻana i ka BPA a me nā phthalates
• Ke laina lalo

ʻO ka palaka kahi mea synthetic a semi-synthetic paha i kūpaʻa, māmā, a maʻalahi.

ʻAe kēia mau waiwai iā ia e hana i nā huahana like ʻole, e like me nā lako olakino, nā ʻāpana kaʻa, a me nā waiwai o ka hale e like me nā ipu mālama meaʻai, nā ipu mea inu, a me nā kīʻaha ʻē aʻe.

Eia nō naʻe, noʻonoʻo paha ʻoe hiki iā ʻoe ke palekana me ka polu uila e hoʻomākaukau ai i ka meaʻai, hoʻomehana i kāu mea inu punahele, a hoʻomaʻamaʻa hou i nā koena.

Hōʻike kēia ʻatikala inā hiki iā ʻoe ke palekana me ka polu uila.

Nā ʻano ea

ʻO ka palakiko kahi mea i piha i nā kaulahao lōʻihi o nā polymers, i loaʻa i loko o kahi mau kaukani mau ʻāpana hou i kapa ʻia he monomers ().

ʻOiai e hana maʻamau ʻia mai ka aila a me ke kinoea kūlohelohe, hiki ke hana ʻia nā plastics mai nā mea hou e like me ka lāʻau pulp a me nā linters pulupulu ().

Ma ke kumu o ka hapanui o nā huahana ea, e ʻike ʻoe i kahi huinaha hoʻopulapula me kahi helu - ka helu ʻike resin - mai ka 1 a i ka 7. ʻ tellslelo ka helu iā ʻoe i ke ʻano o ka ea i hana ʻia ai ().

ʻO nā ʻano ʻehiku o nā ea a me nā huahana i hana ʻia mai iā lākou e ((3):

1. Polyethylene terephthalate (PET a PETE paha): nā hue inu soda, ka pata, a me nā ipu mayonnaise, a me nā ipu ʻaila kuke
2. ʻO polyethylene kiʻekiʻe (HDPE): nā mea holoi a me nā ipu kopa lima, nā ipu waiū, nā ipu bata, a me nā pauka pauka protein
3. ʻO Polyvinyl chloride (PVC): paipu paipu, uwea uila, pale pale, paipu lapaʻau, a me nā huahana ʻili synthetic
4. ʻO ka polyethylene haʻahaʻa haʻahaʻa (LDPE): ʻeke ʻeke, ʻomi ʻōmole, a me nā pūʻolo ʻai
5. Polypropylene (PP): nā pāpale ʻōmole, nā ipu yogurt, nā ipu mālama meaʻai, nā capsule kope lawelawe hoʻokahi, nā ʻōmole pēpē, a me nā ʻōmole haʻalulu
6. ʻO Polystyrene a i ʻole Styrofoam (PS): hāʻawe ʻana i ka pī a me nā ipu meaʻai hiki ʻole ke hoʻohana ʻia, nā pā, a me nā kīʻaha kīnā ʻole
7. Other: nā polycarbonate, polylactide, acrylic, acrylonitrile butadiene, styrene, fiberglass, a me nylon

Loaʻa i kekahi o nā plastics nā mea hoʻohui e hoʻokō i nā waiwai i makemake ʻia o ka huahana i hoʻopau ʻia (3).

Hoʻopili kēia mau mea hoʻohui i nā mea kala, nā mea hoʻoikaika, a me nā mea hoʻopaʻa.

Hana mua ʻia ka lula mai ka aila a me ka ʻaila kūlohelohe. Nui a hewahewa nā ʻano palapū i loaʻa nā ʻano noi like ʻole.

Pakele paha i ka ea ea?

ʻO ka mea nui e hopohopo nei me ka plastic microwave ka mea hiki ke hoʻoulu i nā mea hoʻohui - kekahi o nā mea ʻino - e komo i loko o kāu mau meaʻai a me nā mea inu.

ʻO nā kemikal mua o ka hopohopo he bisphenol A (BPA) a me kahi papa o nā kemika i kapa ʻia ʻo phthalates, hoʻohana ʻia ia mau mea ʻelua e hoʻonui i ka maʻalahi a me ka paʻa o ka ea.

ʻO kēia mau kemikū - ʻoi aku ka BPA - hoʻohaunaele i nā homone o kou kino a ua hoʻopili ʻia i ka momona, diabetes, a me nā mea hoʻohua reproductive (,,).

ʻIke ʻia ka BPA ma nā plastics polycarbonate (PC) (helu 7), i hoʻohana ākea ʻia mai nā makahiki 1960 e hana i nā waihona waihona meaʻai, nā aniani inu, a me nā ʻōmole pēpē ().

Hiki i ka BPA mai kēia mau lula ke komo i loko o nā meaʻai a me nā mea inu i ka manawa, a i ka wā e ʻike ʻia ai ka ea i ka wela, e like me ka microwaved (,,).

Eia nō naʻe, i kēia lā, ua hoʻololi kekahi mau mea hana i ka hoʻomākaukau ʻana o ka meaʻai, mālama, a me nā huahana lawelawe i ka plastic PC no ka ea BPA-ʻole e like me PP.

Pāpā pū ka Food and Drug Administration (FDA) i ka hoʻohana ʻana o nā mea hoʻokumu BPA i ka hoʻopili pēpē pēpē, nā kīʻaha sippy, a me nā ʻōmole pēpē ().

Eia nō naʻe, ua hōʻike ʻia nā noiʻi hiki i nā Plastics manuahi BPA ke hoʻokuʻu i nā kemikona hoʻoweliweli e like me ka phthalates, a i ʻole nā ​​mea ʻē aʻe BPA e like me bisphenol S a me F (BPS a me BPF), i nā meaʻai ke microwaved (,,,).

No laila, he mea maikaʻi loa e hōʻalo i ka plastic microwave, ke ʻole - e like me ka FDA - kapa inoa pono ʻia ka ipu no ka hoʻohana ʻana o ka hawewe ().

Hiki i ka plastic plastic ke hoʻokuʻu i nā kemika weliweli e like me BPA a me nā phthalates i kāu mau meaʻai a me nā mea inu. No laila, pono ʻoe e hōʻalo i ka plastic microwave, ke ʻole i lepili ʻia no kēia hoʻohana kikoʻī.

Nā ala ʻē aʻe e hōʻemi ai i kou hōʻike ʻana i ka BPA a me nā phthalates

ʻOiai ʻo ka microwave plastic e hōʻeleu i ka hoʻokuʻu ʻana o BPA a me nā phthalates, ʻaʻole wale ia ke ala e hoʻopau ai kēia mau kemika i kāu meaʻai a mea inu paha.

Nā kumu ʻē aʻe i hiki ke hoʻonui i ka leaching kemika me (,):

• ke waiho nei i nā meaʻai i loko o nā ipu ea i wela mau
• 'ōpala i nā ipu e hoʻohana ana i nā mea abrasive, e like me ka hulu kila, i hiki ke kumu i ka ʻōpala
• me ka hoʻohana ʻana i nā ipu no kahi manawa lōʻihi
• Ke hōʻike pinepine nei i nā ipu i ka mea holoi pā ma ka manawa

Ma ke ʻano he rula, pono e hoʻololi ʻia nā ipu ea i naha, ʻāhaʻi, a i ʻole hōʻike i nā hōʻailona o ke komo a me nā ipu ea ʻaʻano BPA hou ʻole a i ʻole nā ​​ipu i hana ʻia mai ke aniani.

I kēia lā, hana ʻia nā ipu mālama meaʻai he nui mai BPA-noa PP.

Hiki iā ʻoe ke ʻike i nā ipu i hana ʻia mai PP ma ka nānā ʻana ma lalo no ka peʻa PP a i ʻole kahi hōʻailona hana hou me ka helu 5 ma waenakonu.

ʻO ka wahī meaʻai lula e like me ka wahī lula hiki ke loaʻa iā BPA a me nā phthalates ().

E like me ia, inā pono ʻoe e uhi i kāu meaʻai i loko o ka hawewe, e hoʻohana i ka pepa wax, ka pepa a i ʻole kahi kāwele pepa.

ʻO nā ipu ea i wili ʻia, ʻino, a i ʻole lole weluwelu nui paha, e hoʻoweliweli ʻia i ka leaching kemika.

Ke laina lalo

ʻO nā Plastics he mau mea i hana mua ʻia mai ka aila a me ka aila, a he ʻano like ʻole kā lākou noi.

ʻOiai ka nui o ka mālama ʻana i ka meaʻai, hoʻomākaukau, a me nā huahana lawelawe i hana ʻia mai ka palakiko, hiki i ka microwaving iā lākou ke hoʻonui i ka hoʻokuʻu ʻana o nā kemikino weliweli e like me BPA a me nā phthalates.

No laila, inā ʻaʻole i manaʻo ʻia ka palekana o ka huahana ea, pale i ka microwaving iā ia, a hoʻololi i nā ipu palolo i komo me nā mea hou.
