Raws li kev soj ntsuam saum toj no ntawm cov khoom txwv tsis pub, peb tuaj yeem ua pov thawj qhov kev sau npe ntawm cov khoom nrov hauv qab no.
Glufosinate tuaj yeem ua rau muaj kev phom sij
Glufosinate-ammonium yog levorotatory isomer ntawm glufosinate-ammonium. Glufosinate nws tus kheej yog ib haiv neeg sib xyaw ua ke ntawm L-Glufosinate-ammonium thiab D-Glufosinate-ammonium.
Cov kev tshawb fawb tau pom tias ntawm cov isomers sib xyaw, cov tshuaj tua kab mob tiag tiag yog L-glufosinate, uas yog glufosinate essence. Tom qab enriching cov isomers uas yeej siv tshuaj tua kab mob, cov nyhuv tib yam yuav raug exerted, ntau npaum li cas ntawm glufosinate-ammonium yuav raug txo kom tsawg, thiab cov kev pheej hmoo ntawm daim ntawv thov kuj yuav raug txo.
Txij li thaum glufosinate-ammonium raug txwv hauv EU, puas tuaj yeem glufosinate-ammonium txuas ntxiv mus thov rau EU rau npe?
Lub ntsiab yog vim li cas rau kev txwv tsis pub ntawm glufosinate-ammonium yog tias nws raug cais raws li kev ua me nyuam thiab kev loj hlob toxicity qeb 1B, uas ua tau raws li EU tshuaj txwv txiav tus qauv, thiab tus neeg thov kev pab tsis txhawb nws. Yog li ntawd, yog tias glufosinate-ammonium muaj qhov sib txawv ntawm kev phom sij, nws muaj peev xwm xa daim ntawv thov kev pom zoo rau EU dua. Ib qho piv txwv zoo li no tau tshwm sim hauv EU. Piv txwv li, metolachlor raug txwv hauv EU, tab sis metolachlor phev raug pom zoo.
Kev tshawb fawb tam sim no qhia tau hais tias txoj hauv kev metabolic ntawm glufosinate-ammonium yuav txawv ntawm glufosinate-ammonium, thiab kev faib tawm ntawm glufosinate-ammonium yuav tsis sib haum nrog glufosinate-ammonium. Yog li ntawd, ua ntej lub tuam txhab xa daim ntawv thov kev sau npe, lub ntsiab lus tseem ceeb yuav tsum tau lees paub hauv kev tshawb fawb thiab kev tsim kho thiab kev ntsuam xyuas ua ntej muaj kev pheej hmoo yog kev ua me nyuam thiab kev loj hlob toxicity ntawm glufosinate-ammonium.
Glyphosate tuaj yeem ua rau muaj kev phom sij
Hauv kev ntsuam xyuas zaum kawg, rau ntau yam laj thawj, glyphosate tsuas yog tso cai rau 5- xyoo siv tau.
Tom qab kev pom zoo, qhov kev rov ntsuam xyuas dua tom ntej tau pib tam sim ntawd. Lub EU xa Fabkis, Hungary, Netherlands thiab Sweden los tsim ib pab neeg soj ntsuam glyphosate muaj zog, uas ua tiav cov kev ntsuam xyuas cov qauv xyoo tas los.
Txawm hais tias daim ntawv ntsuam xyuas pom tau tias glyphosate tau ua tiav raws li qhov yuav tsum tau pom zoo, cov neeg feem coob tseem xav tias tseem muaj ntau qhov tsis paub meej txog seb glyphosate puas tau pom zoo. Kev tsis sib haum xeeb txuas ntxiv mus seb glyphosate puas yog carcinogenic. Txawm hais tias kev tshuaj xyuas ntawm glyphosate tseem tsis tau xaus, tsoomfwv German tau dhau txoj cai hais tias glyphosate yuav raug txwv tsis pub dhau xyoo 2024.
Xyoo no, txawm li cas los xij, muaj xov xwm zoo rau kev pom zoo ntawm glyphosate, uas yog qhov kawg ntawm CLP kev faib tawm ntawm glyphosate. Ntawd yog, nyob rau lub Tsib Hlis ntawm lub xyoo no, ECHA tau tshaj tawm cov lus xaus kawg ntawm kev faib phom sij ntawm glyphosate, lees paub tias glyphosate tsis muaj kev faib tawm carcinogenic.
Lub hom phiaj ntawm kev sib tham yav dhau los ntawm glyphosate yog carcinogenicity. Qhov kev faib tawm no yog qhov xov xwm zoo rau kev pom zoo ntawm glyphosate. Tam sim no kev phom sij ntawm glyphosate ua tau raws li cov kev cai yooj yim rau EU kev pom zoo. Yog tias qhov kev rov qab mus zoo, nyob rau yav tom ntej. Nyob rau yav tom ntej, peb tuaj yeem tos ntsoov rau qhov kev pom zoo ntawm glyphosate hauv EU.
❸ Cov Neeg Sib Tw Hloov Cov Tshuaj
Cov neeg sib tw hloov cov tshuaj yog cov tshuaj uas txhua tus neeg txhawj xeeb tshaj plaws txog kev txwv. Puas muaj qhov tshwm sim siab uas cov tshuaj no yuav raug txwv?
Raws li cov ntaub ntawv pom zoo ntawm EU cov tshuaj nquag, tam sim no muaj 91 tus neeg sib tw lwm yam tshuaj hauv EU, ntawm 53 cov khoom raug pom zoo, suav txog 11.2 feem pua ntawm tag nrho cov tshuaj tau pom zoo, thiab 38 yam khoom tsis raug pom zoo, suav rau {{5 }}.04 feem pua ntawm tag nrho cov khoom tsis pom zoo .
Nws tuaj yeem pom tau tias feem ntau ntawm cov neeg sib tw hloov cov tshuaj tsis raug txwv tsis pub muaj ntau lossis cov txheeb ze, tab sis feem ntau ntawm lawv yog nyob rau hauv lub xeev tau pom zoo, yog li tsis tas yuav txhawj xeeb ntau dhau txog kev pheej hmoo ntawm cov neeg sib tw tshuaj raug txwv.
Cov neeg sib tw hloov cov tshuaj yog cov tshuaj phem, tab sis lawv tsis ua raws li cov qauv kev txwv. Rau kev sau npe ntawm cov khoom siv no, kev saib xyuas ntxiv yuav tsum tau them rau qhov kev ntsuas kev pheej hmoo ntawm cov khoom. Thaum cov kev pheej hmoo siv tau tswj tau, lawv feem ntau yuav tsis raug txwv.
Feem ntau, EU txoj cai tshuaj tua kab tsis yog tsuas yog kev tswj hwm kev pheej hmoo, tab sis kuj yog txoj cai tswj hwm kev phom sij. Thaum muaj kev phom sij ntawm cov khoom siv hluav taws xob nce mus txog ib theem, qhov kev ntsuam xyuas kev pheej hmoo tsis tau ua tiav, thiab cov khoom siv sib txuas tau raug txwv ncaj qha. Nyob rau hauv cov xwm txheej uas qhov kev puas tsuaj yog OK, txhua yam khoom tseem yuav tsum tau xyuas kom meej tias qhov kev pheej hmoo ntawm kev siv yog tswj tau ua ntej nws tuaj yeem pom zoo.
