A iphepha elitsha lezesayensi Ukuvavanya iimpembelelo ezinokubakho kwezempilo zeRoundup herbicides kufumanise unxibelelwano phakathi kokuchasana nokhula olubulala ikhemikhali glyphosate kunye nokonyuka kohlobo lwe-amino acid eyaziwa ngokuba ngumngcipheko wesifo sentliziyo.

Abaphandi benza izigqibo zabo emva kokubhengeza iigundane ezikhulelweyo kunye neentsana zabo ezisandul 'ukuzalwa kwi-glyphosate kunye neRoundup ngamanzi okusela. Bathe bajonge ngokukodwa kwiziphumo ze-glyphosate-based herbicides (GBH) kwiimetabolites zomchamo kunye nokunxibelelana ne-gut microbiome kwizilwanyana.

Abaphandi bathi bafumene ukonyuka okubonakalayo kwe-amino acid ebizwa ngokuba yi-homocysteine ​​kwiintsana zamaduna ezivezwe kwi-glyphosate nakwiRoundup.

"Uphononongo lwethu lubonelela ngobungqina bokuqala bokuba ukubhencwa kwi-GBH esetyenziswa ngokuxhaphakileyo, kumthamo wokubonisa ukubonwa kwabantu okwamkelekileyo okwangoku, kunakho ukuguqula umchamo kwimetabolites kuzo zombini iirati zabantu abadala kunye namantshontsho," utshilo umphandi.

Eli phepha linesihloko esithi “Ukuvezwa kwethamo elisezantsi lokutshabalalisa ukhula lwe-glyphosate-based herbicides kuphazamisa i-metabolism yomchamo kunye nokunxibelelana kwayo ne-gut microbiota,” libhalwe ngabaphandi abahlanu abasebenzisana ne-Icahn School of Medicine kwiNtaba yeSinayi eNew York kunye nezine ezivela eRamazzini Institute eBologna, e-Itali. Yapapashwa kwijenali yeeNgxelo zezeNzululwazi ngoFebruwari 5.

Ababhali bavumile uninzi lwezithintelo kufundo lwabo, kubandakanya nesampulu encinci, kodwa bathi umsebenzi wabo ubonakalisile ukuba "ukubonakaliswa kwethamo eliphantsi kunye nobomi obuncinci kwi-glyphosate okanye iRoundup kutshintshe kakhulu umchamo kwi-biomarker yomchamo, emadamini nakwinzala."

Uphononongo lolokuqala kwiinguqu kwimichamo ye-metabolism ye-urinary eyenziwe yi-glyphosate-based herbicides kwiidosi ekujongwa ukuba zikhuselekile ebantwini, abaphandi bathi.

Eli phepha lilandela ukupapashwa kwinyanga ephelileyo isifundo kwiphephancwadi Imiba yezeMpilo efumene i-glyphosate kunye nemveliso ye-Roundup inokutshintsha ukwakheka kwe-gut microbiome ngeendlela ezinokuthi zinxulunyaniswe neziphumo ezibi zempilo. Inzululwazi ezivela eRamazzini Institute nazo zazibandakanyekile kolo phando.

URobin Mesnage, ongomnye wababhali bephepha elipapashwe kwinyanga ephelileyo kwiiNkqubo zeMpilo yezeNdalo, uthathe umba ngokunyaniseka kwephepha elitsha. Uthe uhlalutyo lwedatha lubonisa iyantlukwano efunyenwe phakathi kwezilwanyana ezivezwe kwi-glyphosate kunye nezo zingatyhilelwanga- izilwanyana ezilawulayo- zinokufunyanwa ngokufanayo nedatha eveliswe ngokungacwangciswanga.

"Ngokubanzi, uhlalutyo lwedatha alusixhasi isigqibo sokuba i-glyphosate iphazamisa umchamo kwimetabolome kunye ne-gut microbiota yezilwanyana eziveziweyo," utshilo uMesnage. "Olu phononongo luya kuphinda luqhubeke ludida nje ingxoxo malunga nobutyhefu be-glyphosate."

Izifundo ezininzi zamva nje kwi-glyphosate kunye ne-Roundup bafumene uluhlu lweenkxalabo.

I-Bayer, eyazuza njenge-Monsanto's glyphosate-based herbicide brand kunye ne-glyphosate-tolerant portal seeded portfolio yayo xa yayithenga inkampani kwi-2018, igcina ukuba ubuninzi besifundo senzululwazi kumashumi eminyaka buqinisekisa ukuba i-glyphosate ayibangeli mhlaza. I-Arhente yokuKhuselwa kokusiNgqongileyo e-US kunye neminye imibutho emininzi yamazwe aphesheya nayo ayithathi njengemveliso ye-glyphosate njenge-carcinogenic.

Kodwa i-Arhente yeHlabathi yezeMpilo yoPhando ngomhlaza kwi-2015 yathi uphononongo lophando lwenzululwazi lufumene ubungqina obaneleyo bokuthi i-glyphosate yinto enokubangela i-carcinogen yabantu.

I-Bayer ilahlekelwe zizilingo ezintathu kwezintathu eziziswe ngabantu abagxeka i-cancer yabo ekuvezeni i-Monsanto's herbicides, kwaye i-Bayer kunyaka ophelileyo ithe izakuhlawula i-11 yezigidigidi zeedola ukuhlawula ngaphezulu kwe-100,000 amabango afanayo.
