Loaʻa maoli ka arsenic i loko o nā minelala, ka wai honua, a me nā sediments. Hoʻonui hou nā hana ʻoihana a me ka hana ʻeli ʻana i ka arsenic i ka lepo a me ka wai. Hoʻopili nā mea kanu meaʻai i ka arsenic mai kēia mau kumu, e alakaʻi ana i ka haumia. He mea ʻawahia loa ka arsenic inorganic; ʻo ka hoʻohana mau ʻana e hoʻoulu ai i nā ʻeha ʻili, nā maʻi cardiovascular, neurotoxicity, a me nā pilikia kanesa i hōʻoia ʻia e nā loiloi pilikia EFSA. Hoʻonohonoho ka World Health Organization i ka palena kiʻekiʻe o 10 µg/L no ka arsenic i ka wai inu; ua kaupalena ka US FDA i ka arsenic i loko o ka cereal laiki pēpē i 100 ppb.

Nā Kumu a me ka Hopena ma ka Palekana Meaʻai
ʻO ka laiki, ʻoiai ka laiki ʻeleʻele, e hōʻiliʻili i ka arsenic inorganic mai nā mauʻu i piha i ka wai. Hōʻike nā huaʻai, nā mea kanu, a me nā wai huaʻai i nā pae kiʻekiʻe ma nā wahi haumia. Ke kū nei nā mahiʻai i ka lawe ʻia mai ka hoʻoinu ʻana me ka wai i hoʻopiha ʻia me ka arsenic. Pono nā mea hana meaʻai e nānā i nā meaʻai maka; nānā nā keʻena hoʻokolohua kaiapuni i ka lepo no ka palekana mahiʻai. Kuhi nā keʻena hoʻoponopono i nā wahi wela me ka hoʻohana ʻana i ka hoʻāʻo kahua a me ka nānā ʻana i ka hale hana. Hōʻike nā ʻike EFSA hou loa i ka laiki a me nā meaʻai i hana ʻia me ka cereal ma ke ʻano he mau mea kōkua nui i ka hōʻike ʻana i ka arsenic i ka ʻai, e paipai ana i ka nānā pono ʻana a me nā hana hoʻēmi.
ʻO ka X-Ray Fluorescence Spectroscopyno ka ʻike ʻana i ka Arsenic
ʻIke ka spectroscopy fluorescence X-ray i ka arsenic elemental i loko o nā matrices paʻa ma ka ʻike ʻana i nā hoʻokuʻu X-ray maʻamau ma hope o ka hoʻomālamalama ʻana o ka laʻana. Hoʻohālikelike pololei ʻo XRF i ka arsenic inorganic i loko o ka lepo a me nā meaʻai—me ka laiki a me nā palaoa—me ka hoʻomākaukau liʻiliʻi ʻana o ka laʻana, e kākoʻo ana i ka palekana o ka meaʻai a me ke kūlike o ke kaiapuni me ka hiki ke hana hou ʻia. Ma ke ʻano he loiloi kūlana paʻa, pale ʻo XRF i nā ʻōpala wai a me nā reagents weliweli i hoʻohana ʻia i ka kemika pulu, e hoʻemi ana i ka pilikia o ka mea hana. Hoʻonui nā kaʻina hana XRF e pili ana i ka nitrate kālā i nā palena ʻike, e hiki ai ke ʻike i ka pae picogram i loko o nā matrices paʻakikī, a hōʻike i kahi koho palekana no ke kaiapuni. ʻOi aku ka maikaʻi o XRF ma ka palapala wikiwiki ʻana i nā wahi wela arsenic ma nā kahua haumia, nā papahana hoʻoponopono, a me nā laina hana meaʻai.
ʻO ka Lonnmeter XRF Analyzer Solution
ʻO Lonnmeter XRF Analyzer: Nā Hiʻohiʻona a me nā Palena
Hāʻawi ka mea loiloi Lonnmeter XRF i ka ʻike pololei ʻana i ka arsenic inorganic i loko o ka meaʻai paʻa, ka lepo, a me nā laʻana kaiapuni me ka hoʻohana ʻana i ka ʻenehana hoʻolaha wavelength holomua. Hiki i ka hoʻolālā lawe lima ke ana wikiwiki ma ka pūnaewele me ka ʻole o nā pono hana hoʻokolohua. Mālama nā hiʻohiʻona palekana i nā mea hana mai ka hōʻike ʻana o ka x-ray, ʻoiai nā hana calibration paʻa e hoʻohana i nā mea kuhikuhi i hōʻoia ʻia no ka pololei hiki ke hahai ʻia. Hoʻololi nā ʻikepili loiloi hiki ke hoʻopilikino ʻia i ka laiki, nā palaoa, ka lepo, a me nā meaʻai i hana ʻia. ʻO ka hoʻohālikelike ʻana me nā matrices like ʻole e hōʻoia i ka helu maʻamau no ka ʻoihana a me nā noi hoʻoponopono.
Nā Pōmaikaʻi o ka Hoʻohana ʻana iā XRF no ka Nānā ʻana o Arsenic
Hoʻokō ka spectroscopy fluorescence X-ray i ka nānā ʻana o ka arsenic kiʻekiʻe me ka ʻole o nā reagents weliweli a i ʻole ka lawelawe ʻana i nā laʻana e hana nui ana, e hōʻemi ana i ka manawa loiloi ma 70% i hoʻohālikelike ʻia me nā ʻano ICP-MS kuʻuna. ʻO ka ʻole o ka unuhi kemika e hōʻike ana i ka emi ʻana o ka pilikia o ka haumia a i ʻole ka nalowale ʻana o ka analyte. Hōʻike nā noiʻi i loiloi ʻia e nā hoa hou i ka pololei a me ka hilinaʻi like me ka kemika pulu maʻamau, e kākoʻo ana i ka mālama ʻana i nā lula a me ka nānā ʻana i ke kaiapuni. ʻO ka mālama kālā ʻana i nā reagents a me ka mālama ʻana i nā kahawai ʻōpala e hoʻolilo i ka mea loiloi Lonnmeter i mea kūpono no ka hoʻāʻo maʻamau i ka palekana o ka meaʻai, ka hoʻoponopono ʻana i ka lepo, a me ka nānā ʻana i nā metala kaumaha.
Pehea e hoʻoponopono ai ʻo Lonnmeter i nā pilikia koʻikoʻi
Hāʻawi ʻo Lonnmeter i ka helu ʻana o ka arsenic hiki ke hana ʻia no nā mea hana a me nā keʻena hoʻokolohua kaiapuni, e kākoʻo ana i ka hoʻēmi ʻana i ka pilikia e kūlike me nā kūlana olakino o kēia manawa. Hōʻoia nā protocols calibration i hoʻohui ʻia i nā ana hiki ke hana hou ʻia ma nā pae āpau—mai nā nānā ʻohi a hiki i ka nānā ʻana i nā huahana i hoʻopaʻa ʻia. Mālama nā hiʻohiʻona calibration aunoa i ka ʻike a hoʻoponopono i nā hopena matrix, e hoʻopau ana i nā hoʻoponopono lima. Hiki i nā hopena manawa maoli ke hoʻopaʻa wikiwiki i ka hoʻokō ʻana, hoʻomaʻamaʻa i ka ʻike ʻana i nā loiloi hoʻoponopono, a kākoʻo i nā mea hana meaʻai e kū nei i ka haumia arsenic inorganic i ka laiki, nā palaoa, a me ka lepo.
E noi i kahi ʻōlelo kūʻai no ka Lonnmeter XRF Analyzer
No ke aha e koho ai iā Lonnmeter no ka ʻike ʻana i ka Arsenic?
Kākoʻo ka mea loiloi Lonnmeter XRF i ka mālama ʻana i nā lula no ke ana ʻana i ka haumia arsenic inorganic i ka palekana meaʻai, ka lepo, a me nā matrices kaiapuni me ka hoʻohana ʻana i ka spectroscopy fluorescence x-ray. Hoʻokipa nā ʻōlelo maʻamau i ka throughput laʻana kikoʻī, nā pae haumia, a me nā koi mālama ma nā noi like ʻole.

He aha ka pōmaikaʻi nui o ka spectroscopy fluorescence x-ray no ka ʻike ʻana i ka arsenic?
ʻO ka spectroscopy fluorescence X-ray e hiki ai i ka loiloi quantitative, non-destructive, a me multi-element o nā mea paʻa e like me ka lepo, ka laiki, a me nā pauka meaʻai. ʻAʻole koi ka loiloi i ka ʻeli ʻana o ka hāpana, e hōʻemi ana i ka huli ʻana i nā minuke me ka hoʻēmi ʻana i ka pilikia o ka haumia.
Pehea e hoʻopilikia ai ka arsenic inorganic i ka meaʻai i ke olakino?
ʻO ka lawe mau ʻana i ka arsenic inorganic i ka meaʻai hiki ke hoʻoulu i nā ʻeha ʻili, nā maʻi cardiovascular, nā maʻi neurological, a me ke kanesa māmā a me ka ʻōpū mimi. Ke hōʻike nei ka European Food Safety Authority a me WHO he mea nui ka laiki, nā cereals, a me nā meaʻai i loaʻa mai ka limu i ka nui o ka arsenic i ka ʻai. ʻO nā keiki a me nā wahine hāpai ka mea maʻalahi loa.
