Hom kev ua thiab kev txhim kho ntawm glyphosate

Glyphosate yog ib hom organic phosphine tshuaj tua kab herbicide nrog ebroad spectrum extinating. Glyphosate feem ntau yuav tsum tau thaiv lub biosynthesis ntawm cov tshuaj pleev cov amino acid, Tryptophan thiab Tyrosine ntawm Shikimic acid id acid id acid mus. Nws muaj qhov cuam tshuam rau ntawm 5-enolpyruvylshikate-3-phosphate synthease (EPSP synthease) Nrog no biosynthesis ntawm enzymatic cov tshuaj, ua rau shikimic acid txuam nrog vivo. Ib qho ntxiv, lub glyphosate tseem tuaj yeem tuaj yeem buchpress Lwm yam ntawm cov nroj tsuag enzymes thiab cov tsiaj enzyme. Cov metabolism ntawm glyphosate nyob rau hauv cov nroj tsuag siab dua yog qeeb thiab nws tau raug sim tias nws cov metabolite yog aminomethylphosphonic acid thiab methyl amino acetic acid. Vim tias kev ua haujlwm siab ua haujlwm, qeeb li cov nroj tsuag muaj txiaj ntsig zoo nkauj hauv cov nroj tsuag ntawm cov nroj tsuag ntawm cov nroj tsuag ntawm cov nroj tsuag ntawm cov nroj tsuag uas zoo nkauj heev vim nws cov txiaj ntsig tsis yog xaiv tau Thiab cov nyhuv zoo, tshwj xeeb yog nrog thaj chaw loj ntawm glyphosate-tiv taus transgenic cov qoob loo, nws tau dhau los ua neeg tua tsiaj.

Raws li PMA kev txheeb xyuas, Glyphosate tsis muaj genotoxicity thiab tsis tshua muaj kev pheej hmoo rau tib neeg. Tsis muaj kev pheej hmoo rau tib neeg kev noj qab haus huv yuav tsum tau los ntawm kev ntsuas zaub mov (zaub mov thiab dej) uas cuam tshuam nrog kev siv glyphosate; Ua raws li cov lus qhia npe, thiab tsis tas yuav txhawj xeeb txog hom haujlwm uas siv glyphosate lossis kev pheej hmoo rau cov neeg nyob hauv. Tsis muaj kev pheej hmoo rau ib puag ncig yog qhov xav tau raws li cov ntawv yuav tsum tau kho cov khoom siv tsis tau

Nws yog kwv yees tias lub ntiaj teb kev siv glyphosate yuav 600,000 ~ 750,000 t nyob rau hauv 2020, thiab nws yuav tsum yog 740,000 yuav tsum tau muaj 7 xyoo, thiab nws yuav tsum tau muaj kev nce qib siab sai li cas.
