Ka kitea te āheniki i roto i ngā kohuke, i ngā wai whenua, me ngā paru. Ka nui ake te āheniki i roto i te oneone me te wai nā ngā mahi ahumahi me te keri maina. Ka mimitihia e ngā hua kai te āheniki mai i ēnei pūtake, ka puta te poke. He tino paitini te āheniki kore-ora; ka puta he whara kiri, he mate pūnaha toto, he paitini roro, me ngā mōrearea mate pukupuku i te wā roa, ā, kua whakaūtia e ngā aromatawai mōrearea a te EFSA. Ka whakatakoto te Whakahaere Hauora o te Ao i te 10 µg/L mō te āheniki i roto i te wai inu; ka whakawhāitihia e te US FDA te āheniki i roto i te pata raihi pēpi ki te 100 ppb.

Ngā Pūtake me ngā Pānga ki te Haumaru Kai
Ka kohia te raihi, inā koa te raihi parauri, e te āheniki kore-ora mai i ngā pāmu waipuke. E whakaatu ana ngā witi, ngā huawhenua, me ngā wai hua i ngā taumata teitei i ngā wāhi poke. Ka pāngia ngā kaipāmu e te mimiti mai i te whakamakuku me te wai kapi i te āheniki. Me tirotirohia e ngā kaihanga kai ngā kai mata; ka aroturukihia e ngā taiwhanga taiao te oneone mō te haumaru ahuwhenua. Ka tautuhia e ngā tari whakahaere ngā wāhi wera mā te whakamahi i ngā whakamātautau mara me te tātari taiwhanga. E whakaatu ana ngā kitenga hou a te EFSA i te raihi me ngā kai e ahu mai ana i te pata hei tino take o te pānga o te āheniki ki te kai, me te tūtohu kia kaha ake te aroturuki me ngā mahi whakaiti i te mate.
Te Matawai Hiko-Xmō te kimi i te ārsenika
Mā te tirotiro hihi-X ka tautuhia te āheniki huānga i roto i ngā matihiko totoka mā te kite i ngā tukunga hihi-X āhuatanga i muri i te whakamātaotanga tauira. Ka tatau tika a XRF i te āheniki kore-ora i roto i ngā oneone me ngā kai—tae atu ki te raihi me ngā witi—me te iti o te whakarite tauira, e tautoko ana i te haumaru kai me te tutuki i te taiao me te āheinga whakahoki kua whakamātauhia. Hei tātari āhua-totoka, ka karohia e XRF ngā para wai me ngā matū kino e whakamahia ana i roto i te matū mākū, ka whakaitihia te mōrearea o te kaiwhakahaere. Ka whakawhānuihia e ngā tikanga XRF e hangai ana ki te hauota hiriwa ngā rohe kitenga, ka taea ai te aro ki te taumata picogram i roto i ngā matihiko uaua, ā, ka whakaatu i tētahi huarahi haumaru ake mō te taiao. He tino pai a XRF ki te mahere tere i ngā wāhi wera āheniki puta noa i ngā mara poke, ngā kaupapa whakaora, me ngā raina whakaputa kai.
Te Otinga Tātari Lonnmeter XRF
Kaitātari Lonnmeter XRF: Ngā Āhuatanga me ngā Tawhā
Mā te tātaritanga Lonnmeter XRF ka kitea tika te āheniki kore-waro i roto i ngā kai totoka, te oneone, me ngā tauira taiao mā te whakamahi i te hangarau horapa roangaru matatau. Ka taea e te hoahoa kawe te ine tere i te papaanga me te kore he hanganga taiwhanga. Ka tiakina e ngā āhuatanga haumaru ngā kaiwhakahaere mai i te pānga o te hihi-X, ko ngā mahi whakatikatika pakari ka whakamahi i ngā rauemi tohutoro whaimana mō te tika ka taea te whai. Ka urutau ngā kōtaha tātaritanga ka taea te whakarite ki te raihi, ki ngā witi, ki te oneone, me ngā kai tukatuka. Mā te hototahi ki ngā matrices kanorau ka whakarite i te ine paerewa mō ngā tono ahumahi me ngā ture.
Ngā Painga o te Whakamahinga o te XRF mō te Tātaritanga Āsenika
Mā te mātakitaki ira-X ka taea te tirotiro i te āheni me te kore he matū kino, he mahi nui rānei hei whakahaere i ngā tauira, ka whakaitihia te wā tātari mā te 70% ki te whakataurite ki ngā tikanga ICP-MS tuku iho. Ko te kore tango matū he iti ake te mōrearea o te poke, te ngaronga rānei o te tātaritanga. E whakaatu ana ngā rangahau arotake-ā-hoa tata nei i te tika me te pono rite ki te matū mākū tuku iho, e tautoko ana i te tutuki i ngā ture me te aroturuki taiao. Mā te penapena i ngā matū me te maimoatanga awa para ka whai hua te tātaritanga Lonnmeter mō ngā whakamātautau noa i roto i te haumaru kai, te whakaora oneone, me te aroturuki konganuku taumaha.
Te Āhua o te Whakatau a Lonnmeter i ngā Wero Matua
Ka whakaratohia e Lonnmeter te ine i te āheniki ka taea te mahi mā ngā tukatuka me ngā taiwhanga taiao, e tautoko ana i te whakaiti i te mōrearea e hangai ana ki ngā paerewa hauora o nāianei. Mā ngā tikanga whakataurite whakauru ka taea te whakaputa anō i ngā inenga i ngā wāhanga katoa—mai i ngā tirotiro kotinga ki te tirotiro hua kua takaihia. Ka mau tonu te aro o ngā āhuatanga whakataurite aunoa me te whakatau i ngā pānga matihiko, ka whakakore i ngā whakatikatika ā-ringa. Ka taea e ngā hua wā-tūturu te tuhi tere i ngā tuhinga ture, te whakahaere i te kitenga i ngā arotakenga ture, me te tautoko i ngā kaihanga kai e pāngia ana e te poke āheniki kore-ora i roto i te raihi, ngā witi, me te oneone.
Tonoa he Whakatau mō te Lonnmeter XRF Analyzer
He aha i whiriwhiri ai koe i te Lonnmeter mō te kimi i te ārsenic?
Ka tautoko te tātaritanga Lonnmeter XRF i te tutuki i ngā ture mō te ine i te poke o te arsenic inorganic i roto i te haumaru kai, te oneone, me ngā matrices taiao mā te whakamahi i te inenga fluorescence x-ray. Ka tautokohia e ngā utu ritenga te putanga tauira motuhake, ngā taumata poke, me ngā whakaritenga tutuki puta noa i ngā tono kanorau.
Ngā Pātai Auau (FAQs)
He aha te painga matua o te mātai ira-X mō te kimi i te āheniki?
Mā te tirotiro hihi-X ka taea te tātari ine, kore-whakangaro, me te maha-huānga o ngā totoka pēnei i te oneone, te raihi, me te paura kai. Kāore e hiahiatia he nakunaku tauira mō te tātari, ka whakaitihia te hurihanga ki ngā meneti me te whakaiti i te mōrearea poke.
He aha te tūponotanga o te arsenic inorganic i roto i te kai ki te hauora?
Mā te kai tonu i te arsenic kore-waro ka pāngia e ngā whara kiri, ngā mate pūnaha manawa, ngā mate pūnaha io, me te mate pukupuku o te pūkahukahu me te tōngāmimi. E whakamārama ana te Mana Haumaru Kai o Ūropi me te WHO ko te raihi, ngā witi, me ngā kai i ahu mai i te rimu ngā tino take o te nui o te arsenic i roto i te kai. Ko ngā tamariki me ngā wāhine hapu ngā mea tino pāngia e te mate.
