I. Kev Teeb Tsa Tus Qauv: Qhov Sib Npaug Zoo Ntawm Kev Tshawb Fawb thiab Kev Xyaum

Cov kev txwv tsis pub siv tshuaj tua kab uas tau tsim los ntawm Codex Alimentarius Commission (CAC) yog qhov kawg ntawm ntau txhiab txoj kev tshawb fawb txog tshuaj lom. Cov kws tshawb fawb txiav txim siab qhov Maximum No Observed Adverse Effect Level (NOAEL) los ntawm kev sim tsiaj, tom qab ntawd siv 100 npaug ntawm kev nyab xeeb los xam Acceptable Daily Intake (ADI) rau tib neeg. Piv txwv li, ADI rautshuaj chlorpyrifosyog 0.01 mg/kg, txhais tau tias ib tus neeg laus hnyav 60 kg tuaj yeem noj tau 0.6 mg txhua hnub kom muaj kev nyab xeeb.

Tus qauv tam sim no ntawm Tuam TshojGB 2763-2021npog cov kev txwv ntawm cov tshuaj tua kab rau 564 hom tshuaj tua kab thoob plaws 387 pawg khoom noj, sib haum nrog cov cai hauv EU thiab Asmeskas Piv txwv li, qhov txwv rau procymidone hauv leeks yog 0.2 mg / kg hauv Suav teb piv rau 0.1 mg / kg hauv EU. Cov kev sib txawv no yog los ntawm kev noj zaub mov, tsis yog kev tsis pom zoo tseem ceeb ntawm kev nyab xeeb.

II. Kev Tshawb Fawb Txog Kev Ntsuas: Lub Qhov Ntxig ntawm Kev Paub ntawm Cov Cuab Yeej Uas Muaj Tseeb

Cov cuab yeej siv niaj hnub no tuaj yeem txheeb xyuas cov seem ntawmib feem ntawm ib billion (ppb)cov theem. Cov kua chromatography-mass spectrometry (LC-MS) ntes tau qhov sib npaug ntawm kev yaj ib lub noob ntsev hauv pas dej ua luam dej loj Olympic. Qhov kev rhiab heev no txhais tau tias cov seem "tsis pom" tau dhau los ua tsawg. Xyoo 2024, cov tshuaj tua kab niaj hnub tau pom hauv 68% ntawm cov khoom ua liaj ua teb kuaj, tab sis tsuas yog 1.4% dhau qhov txwv - ua pov thawj tias"Kev kuaj pom yog ib txwm muaj, kev ua dhau cov qauv yog tsawg heev."

Lubqhov loj ntawm cov seemqhov tseem ceeb heev. Rau cypermethrin, qhov txwv hauv citrus yog 2 mg / kg. Yuav kom mus txog qhov koob tshuaj txaus ntshai, ib tug yuav tsum noj 200 kg ntawm citrus ua raws li txoj cai - kev ntsuam xyuas kev pheej hmoo tsis muaj laj thawj zoo li ntshai ntsev rooj (qhov nruab nrab ntawm cov tshuaj tua neeg: 3 g / kg).

III. Kev Tswj Xyuas Kev Pheej Hmoo: Kev Tiv Thaiv Ntau Txheej Rau Kev Nyab Xeeb Khoom Noj

Tuam Tshoj Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb tau ua tiav cov kauj ruam los ntawm cov kev pib zoo li"Kev Sib Tw Tshwj Xeeb rau Kev Tswj Xyuas Cov Tshuaj Txwv thiab Kev Txhim Kho Zoo," ua tiav qhov kev ua raws li 97.6% hauv xyoo 2024. Cov txheej txheem Blockchain traceability tam sim no saib xyuas 2,000 lub hauv paus tsim khoom, taug qab 23 cov ntaub ntawv los ntawm thaj chaw ua liaj ua teb mus rau qhov chaw sib cais. Cov neeg siv khoom tuaj yeem luam theej duab QR code kom nkag mus rau cov ntaub ntawv siv tshuaj tua kab thiab cov ntawv qhia hauv chaw kuaj mob.

Thaum ntsib "cov tshuaj tua kab seem" hauv cov ntawv qhia kev sim, cov neeg siv khoom yuav tsum paub txog:kev kuaj pom ≠ kev ua txhaum cai, thiab cov khoom seem me me tsis muaj kev phom sij rau kev noj qab haus huv. Ntxuav cov khoom noj hauv qab dej ntws li 30 vib nas this tshem tawm 80% ntawm cov khoom seem saum npoo av. Qhov txaus ntshai dua yog cov lus hais tias "txhua yam tshuaj tua kab yog cov tshuaj lom," uas hem lub hauv paus ntawm kev ua liaj ua teb niaj hnub no.

Nyob rau hauv lub caij nyoog ntawm thaj av ua liaj ua teb thiab cov pej xeem loj hlob, cov tshuaj tua kab tseem ceeb rau kev ruaj ntseg zaub mov. Los ntawm kev sib txawv "kev kuaj pom" thiab "dhau tus qauv," thiab nkag siab qhov sib txawv ntawm 0.01 mg thiab 1 mg, peb dim ntawm kev xav binary. Kev nyab xeeb zaub mov tsis yog hais txog xoom kev pheej hmoo, tab siskev pheej hmoo uas tau tswj hwm- kev sib koom tes uas yuav tsum tau cov neeg tswj hwm, cov neeg tsim khoom, thiab cov neeg siv khoom los txais yuav kev tshawb fawb dua li kev xav tsis thoob.
