I. Kev teeb tsa tus qauv: Qhov sib npaug ntawm kev tshawb fawb thiab kev xyaum

Cov tshuaj tua kab residue txwv tsim los ntawm Codex Alimentarius Commission (CAC) yog qhov kawg ntawm ntau txhiab ntawm kev tshawb fawb toxicological. Cov kws tshawb fawb txiav txim siab qhov Tsis Txaus Siab Tshaj Plaws Tshaj Plaws (NOAEL) los ntawm kev sim tsiaj, tom qab ntawd siv 100-fold kev nyab xeeb los xam qhov Txais Tau Txais Txhua Hnub (ADI) rau tib neeg. Piv txwv li, ADI rautshuaj chlorpyrifosyog 0.01 mg / kg, txhais tau hais tias ib tug neeg laus 60 kg tuaj yeem noj 0.6 mg ib hnub twg.

Tuam Tshoj tus qauv tam sim noGB 2763-2021npog cov kev txwv qhov seem rau 564 tshuaj tua kab thoob plaws 387 hom zaub mov, dynamically ua raws li cov cai hauv EU thiab US 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 tshwm sim los ntawm kev noj zaub mov zoo, tsis yog kev tsis pom zoo ntawm kev nyab xeeb.

II. Kev Tshawb Fawb Technology: Kev Paub Txog Kev Txawj Ntse ntawm Cov Cuab Yeej Precision

Cov cuab yeej tshuaj ntsuam niaj hnub tuaj yeem txheeb xyuas cov seem ntawmib feem billion (ppb)qib. Cov kua dej chromatography-mass spectrometry (LC-MS) kuaj pom qhov sib npaug sib npaug rau kev ua kua ntsev ib zaug hauv lub pas dej da dej Olympic. Qhov no rhiab heev txhais tau hais tias "tsis paub meej" residues tau dhau los ua tsawg. Hauv xyoo 2024, cov tshuaj tua kab tsis tu ncua tau tshawb pom hauv 68% ntawm cov khoom ua liaj ua teb coj mus kuaj, tseem tsuas yog 1.4% dhau qhov txwv - ua pov thawj tias"Kev kuaj pom muaj ntau, tshaj cov qauv yog tsawg."

Covqhov loj ntawm residuestseem ceeb heev. Rau cypermethrin, qhov txwv hauv citrus yog 2 mg / kg. Txhawm rau kom ncav cuag ib koob tshuaj txaus ntshai, ib tus yuav tsum tau noj 200 kg ntawm citrus raws li kev soj ntsuam kev pheej hmoo ua tsis muaj txiaj ntsig zoo li ntshai cov ntsev ntsev (qhov nruab nrab ntawm cov neeg tuag: 3 g / kg).

III. Kev Tswj Xyuas Kev Nyab Xeeb: Kev Tiv Thaiv Ntau Cov Txheej Txheem rau Kev Nyab Xeeb Khoom Noj

Tuam Tshoj Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb tau nce qib los ntawm kev pib zoo li cov"Kev Sib Tham Tshwj Xeeb ntawm Kev Tiv Thaiv Tshuaj Tiv Thaiv thiab Kev Txhim Kho Zoo," Ua tiav 97.6% kev ua raws li tus nqi hauv xyoo 2024. Blockchain traceability systems tam sim no saib xyuas 2,000 qhov chaw tsim khoom, taug qab 23 cov ntaub ntawv ntsiab lus los ntawm kev ua liaj ua teb mus rau diav rawg. Cov neeg siv khoom tuaj yeem luam theej duab QR cov lej txhawm rau nkag mus rau cov ntaub ntawv siv tshuaj tua kab thiab cov ntawv ceeb toom.

Thaum ntsib nrog "cov tshuaj tua kab" hauv cov ntawv tshaj tawm, cov neeg siv khoom yuav tsum paub txog:nrhiav pom ≠ ua txhaum, thiab cov kab seem seem ua rau tsis muaj kev phom sij rau kev noj qab haus huv. Ntxuav cov khoom hauv qab dej rau 30 vib nas this tshem tawm 80% ntawm cov khoom seem. Qhov txaus ntshai tshaj yog cov lus thov zoo li "txhua yam tshuaj tua kab muaj kev phom sij," uas cuam tshuam rau kev ua liaj ua teb niaj hnub no.

Nyob rau hauv ib lub sij hawm ntawm strained arable av thiab pejxeem kev loj hlob, tshuaj tua kab tseem tseem ceeb rau zaub mov kev ruaj ntseg. Los ntawm kev paub qhov txawv ntawm "kev tshawb nrhiav" los ntawm "hloov cov qauv", thiab nkag siab txog qhov chasm ntawm 0.01 mg thiab 1 mg, peb dim txoj kev xav binary. Kev nyab xeeb zaub mov tsis yog hais txog xoom txaus ntshai, tab sistswj kev pheej hmoo-Txoj kev sib koom tes xav kom cov neeg tswj hwm, cov tsim khoom, thiab cov neeg siv khoom tau txais kev paub txog kev xav txog kev xav.
