I. Dejinta Heerka: Isku-dheelitirka jilicsan ee u dhexeeya Sayniska iyo Dhaqanka

Xadka haraaga sunta cayayaanka ee uu dejiyay Guddiga Codex Alimentarius (CAC) ayaa ah gunaanadka kumanaan daraasado sun ah. Saynis yahanadu waxay go'aamiyaan Heerka Saamaynta Xun ee Ugu Badan (NOAEL) iyagoo isticmaalaya tijaabooyin xayawaan ah, ka dib waxay codsadaan 100 laab arrimo badbaado si ay u xisaabiyaan qaadashada maalinlaha ah ee la aqbali karo (ADI) ee bini'aadamka. Tusaale ahaan, ADI ee loogu talagalaychlorpyrifoswaa 0.01 mg/kg, taasoo la micno ah in qof weyn oo 60 kg ah uu si badbaado leh u cuni karo 0.6 mg maalintii.

Heerka Shiinaha ee haddaGB 2763-2021Waxay dabooshaa xadka haraaga 564 sunta cayayaanka ee 387 qeybood oo cunto ah, si firfircoon ula jaan qaadaya qawaaniinta EU iyo US Tusaale ahaan, xadka procymidone ee leeks waa 0.2 mg/kg gudaha Shiinaha marka loo eego 0.1 mg/kg gudaha EU. Kala duwanaanshiyaha noocan oo kale ah waxay ka yimaadaan caadooyinka cuntada, ma aha khilaafyada aasaasiga ah ee badbaadada.

II. Tignoolajiyada ogaanshaha: dabinka garashada ee agabka saxda ah

Aaladaha gorfaynta ee casriga ahi waxa ay garan karaan hadhaagaqaybo halkii bilyan (ppb)heerarka. Dareeraha-chromatography-mass spectrometry (LC-MS) waxay ogaataa uruurinta u dhiganta kala dirida hal xabo oo milix ah barkadda dabaasha ee cabbirka Olombikada. Dareenkan macneheedu waa hadhaaga "aan la ogaan karin" ayaa noqda naadir. Sannadkii 2024, hadhaaga sunta cayayaanka caadiga ah ayaa laga helay 68% wax soo saarka beeraha ee la muunadeeyay, laakiin kaliya 1.4% ayaa dhaaftay xadka — taas oo caddaynaysa taas"Ogaanshaha waa wax caadi ah, heerarka dhaafitaanka waa naadir."

Thebaaxadda haraagaarrimaha muhiimka ah. Marka loo eego cypermethrin, xadka liinta waa 2 mg/kg. Si loo gaaro qiyaas khatar ah, qofku wuxuu u baahan yahay inuu isticmaalo 200 kg oo liinta u hoggaansan—qiimaynta khatarta ah oo aan caqli-gal ahayn sida milixda miiska laga cabsado (qiyaasta dhexdhexaadka ah: 3 g/kg).

III. Maareynta Khatarta: Difaaca Badbaadada Cunnada ee Kala Duwan

Wasaaradda Beeraha ee Shiinaha waxay ku tallaabsatay horumarro ay ku tallaabsatay"Ololaha Gaarka ah ee Ku Saabsan Xakamaynta Walxaha Mamnuucay iyo Horumarinta tayada," helitaanka 97.6% heerka u hoggaansanaanta 2024. Nidaamyada raadraaca ee Blockchain hadda waxay kormeeraan 2,000 saldhigyada wax soo saarka, iyagoo la socda 23 dhibcood xogta laga bilaabo beerta ilaa fargeeto. Macaamiishu waxay iskaan karaan koodka QR si ay u helaan diiwaanada isticmaalka sunta cayayaanka iyo warbixinada shaybaadhka.

Marka ay la kulmaan "hadhaaga sunta cayayaanka" ee warbixinnada imtixaanka, macaamiishu waa inay aqoonsadaan:ogaanshaha ≠ xadgudub, iyo hadhaaga raadku ma keenaan khatar caafimaad. Ku-dhaqidda soosaarka biyaha socda hoostooda 30 ilbiriqsi waxay ka saartaa 80% haraaga dusha sare. Khatar badan ayaa ah sheegashada absolutist sida "dhammaan sunta cayayaanka waa waxyeello," kuwaas oo khatar gelinaya aasaaska beeraha casriga ah.

Xilli dhul-beereedku cidhiidhi yahay iyo korodhka dadwaynaha, sunta cayayaanka lagu dilo ayaa ah kuwo lama huraan u ah sugnaanta cuntada. Marka la kala saaro "ogaanshaha" "heerarka ka sarreeya," iyo fahamka farqiga u dhexeeya 0.01 mg iyo 1 mg, waxaan ka baxsaneynaa fikirka binary. Badbaadada cuntadu maaha khatar eber, laakiinkhatarta la maareeyay- dadaal iskaashi oo u baahan nidaamiyeyaasha, soosaarayaasha, iyo macaamiisha si ay u qaataan sayniska oo ka sarreeya dareenka dareenka.
