Amaphepha amatsha e-glyphosate akhomba "ngokungxamisekileyo" kuphando oluninzi malunga nefuthe leekhemikhali kwimpilo yabantu

ushicilelo Imeyli isabelo Ukufuna

Amaphepha enzululwazi asandula ukupapashwa abonisa ubume obuninzi bokhula olubulala ikhemikhali i-glyphosate kunye nesidingo sokuqonda ngcono ifuthe lokuchaphazeleka kwichiza lokubulala izitshabalalisi elithandwayo elinokuba nalo kwimpilo yabantu, kubandakanya impilo ye-gut microbiome.

In elinye lamaphepha amatsha, Abaphandi abavela kwiDyunivesithi yaseTurku eFinland bathi babenako ukufumanisa, “kuqikelelo olulondolozayo,” ukuba malunga neepesenti ezingama-54 zeentlobo zezinto eziphilayo ezingaphakathi kwintsholongwane yomntu emathunjini "zinokuba novakalelo" kwi-glyphosate. Abaphandi bathi basebenzise indlela entsha ye-bioinformatics ukwenza ukufumana.

Ngobuninzi be "bhakteria enkulu" yeentsholongwane ezisemathunjini ezinokufunyanwa yi-glyphosate, ukungeniswa kwe-glyphosate "kunokuchaphazela kakubi ukwakheka kwe-gut microbiome yomntu," batsho ababhali kwiphepha labo, elapapashwa kulenyanga Ijenali yezixhobo ezinobungozi.

Iintsholongwane ezisemathunjini omntu zibandakanya iintlobo ngeentlobo zebacteria kunye nefungi kwaye kukholelwa ukuba zichaphazela imisebenzi yomzimba yokuzikhusela kunye nezinye iinkqubo ezibalulekileyo. Amachiza egciwane angenampilo akholelwa zizazinzulu ezithile ukuba zibe negalelo kuluhlu lwezifo.

"Nangona idatha engeentsalela zeglyphosate kwiinkqubo zesisu somntu isasilela, iziphumo zethu zibonisa ukuba iintsalela zeglyphosate zinciphisa ukwahluka kwebacteria kwaye zilungelelanise ukwakheka kweentlobo zebacteria emathunjini," batsho ababhali. "Singacinga ukuba ukubonakaliswa kweentsalela zeglyphosate ixesha elide kukhokelela kuxinzelelo lweentsholongwane ezinganyangekiyo kwindawo yebacteria."

Iinkxalabo malunga nefuthe le-glyphosate kwintsholongwane yomntu ephuma kwisibakala sokuba i-glyphosate isebenza ngokujolisa kwi-enzyme eyaziwa ngokuba yi-5-enolpyruvylshikimate-3-phosphate synthase (EPSPS.) Le enzyme ibaluleke kakhulu ekudibaniseni iiamino acid eziyimfuneko.

"Ukuchonga eyona mpembelelo ye-glyphosate kwi-gut gut microbiota kunye nezinye izinto eziphilayo, kuyafuneka ukuba kwenziwe uphando olongezelelekileyo lokuveza intsalela ye-glyphosate ekutyeni, ukumisela iziphumo ze-glyphosate emsulwa kunye nokwenziwa kwezorhwebo kwii-microbiomes kunye nokuvavanya ubungakanani i-EPSPS yethu Iimpawu ze-amino acid ziqikelela ubungozi bentsholongwane kwi-glyphosate kwi-vitro nakwizinto ezenzekayo ehlabathini, ”baqukumbela ababhali bephepha elitsha.

Ukongeza kubaphandi abathandathu abavela eFinland, omnye wababhali bephepha unxulumene nesebe le-biochemistry kunye ne-biotechnology eRovira i Virgili University, Tarragona, Catalonia, eSpain.

Iziphumo zempilo yomntu azimiselwanga kwisifundo sethu. Nangona kunjalo, ngokusekwe kwizifundo zangaphambili… siyazi ukuba utshintsho kwi-microbiome yamathumbu omntu lunokudityaniswa nezifo ezininzi, utshilo umphandi weYunivesithi yaseTurku uPere Puigbo kudliwanondlebe.

"Ndiyathemba ukuba uphando lwethu luvula umnyango wokuqhubela phambili kuvavanyo, kwi-vitro nakwintsimi, kunye nezifundo ezisekwe kubemi ukulinganisa isiphumo sokusetyenziswa kwe-glyphosate kubantu nakwezinye izinto eziphilayo," utshilo uPuigbo.

Yaziswa kwi1974

Glyphosate sisixhobo esisebenzayo kwi-Roundup herbicides kunye namakhulu ezinye iimveliso zokubulala ukhula ezithengiswa kwihlabathi liphela. Yaziswa njengombulali wokhula nguMonsanto ngo-1974 yaza yakhula yaba sesona sibulala ntsholongwane sisetyenziswa kakhulu emva kokungeniswa kukaMonsanto ngeminyaka yoo-1990s yezityalo ezakhiwe ngendlela yemfuza ukunyamezela imichiza. Iintsalela zeglyphosate zihlala zifumaneka ekutyeni nasemanzini. Ngenxa yoko, iintsalela zihlala zifunyanwa kumchamo wabantu ababhencwe kwi-glyphosate ngokusebenzisa ukutya kunye / okanye nokusetyenziswa.

Abalawuli baseMelika kunye nomnini weMonsanto uBayer AG bagcina ukuba akukho zinkxalabo zempilo yabantu ngokuchazwa kwe-glyphosate xa iimveliso zisetyenziswa njengoko bekucwangcisiwe, kubandakanya nentsalela ekudleni.

Umzimba wophando ophikisana nala mabango uyakhula, nangona kunjalo. Uphando malunga nefuthe elinokubakho le-glyphosate kwi-gut microbiome aluphantse lomelele njengoncwadi oludibanisa i-glyphosate nomhlaza, kodwa yindawo leyo izazinzulu ezininzi ziyaphanda.

Kwimeko enxulumene noko iphepha epapashwe kule nyanga, iqela labaphandi abavela kwiYunivesithi yaseWashington State naseDuke University bathi bafumene unxibelelwano phakathi kwamanqanaba ebacteria kunye nefungi kumaphecana esisu abantwana kunye neekhemikhali ezifumaneka emakhaya abo. Abaphandi abakhange bajonge i-glyphosate ngokukodwa, kodwa babenjalo wothukile ukuyifumana ukuba abantwana abanamanqanaba aphezulu eekhemikhali eziqhelekileyo zekhaya kwigazi labo babonisa ukunciphisa inani kunye nokwahluka kwebacteria ebalulekileyo emathunjini abo.

IGlyphosate kumchamo

An iphepha lezenzululwazi elongezelelweyo epapashwe kule nyanga igxininise isidingo sedatha engcono kunye nengakumbi xa kuziwa ekuvezweni kwe-glyphosate kunye nabantwana.

Iphepha, elipapashwe kwiphephancwadi LeMpilo yeNdalo ngabaphandi abavela kwiZiko loGuqulelo lwe-Epidemiology kwiSikolo i-Icahn yezoNyango kwiNtaba yeSinayi eNew York, sisiphumo sokuphononongwa koncwadi kwizifundo ezininzi ezixela amaxabiso okwenyani e-glyphosate ebantwini.

Ababhali bathi bahlalutye izifundo ezintlanu ezipapashiweyo kule minyaka mibini idlulileyo yokuxela amanqanaba e-glyphosate alinganiswe ebantwini, kubandakanya nesifundo esinye apho amanqanaba e-urinary glyphosate alinganiswa kubantwana abahlala emaphandleni eMexico. Kwabantwana abangama-192 abahlala kwindawo yaseAgua Caliente, iipesenti ezingama-72.91 zazinamanqanaba afumanekayo e-glyphosate kumchamo wabo, kwaye bonke abantwana abangama-89 abahlala e-Ahuacapán, eMexico, babenamanqanaba afumanekayo okubulala izinambuzane kumchamo wabo.

Nokuba uquka izifundo ezongezelelweyo, zizonke, kukho idatha encinci malunga namanqanaba e-glyphosate ebantwini. Izifundo kwihlabathi liphela zizonke ngabantu abangama-4,299, kubandakanya abantwana abangama-520, abaphandi bathi.

Ababhali baqukumbele ngelithi okwangoku akunakwenzeka ukuba baqonde "ubudlelwane obunokubakho" phakathi kokuvezwa kwe-glyphosate kunye nezifo, ngakumbi ebantwaneni, kuba ukuqokelelwa kwedatha kumanqanaba okuvezwa kwabantu kuncitshisiwe kwaye akumiselweyo.

Baqwalasele ukuba ngaphandle kokunqongophala kwedatha eqinileyo malunga nefuthe le-glyphosate ebantwaneni, inani leentsalela zeglyphosate ezivunyelwe ngokusemthethweni ngabalawuli base-US ekutyeni lenyuke kakhulu kule minyaka idlulileyo.

"Kukho izikhewu kuncwadi lwe-glyphosate, kwaye ezi zithuba kufuneka zigcwaliswe ngokungxamisekileyo, ngenxa yokusetyenziswa okukhulu kwale mveliso kunye nokufumaneka kwayo kuyo yonke indawo," utshilo umbhali uEmanuela Taioli.

Abantwana ngabona basesichengeni sokufumana i-carcinogens yokusingqongileyo kunye nokulandela umkhondo kwiimveliso ezinjenge-glyphosate ebantwaneni "yinto ephambili kwezempilo yoluntu," ngokutsho kwababhali bephepha.

"Njengayo nayiphi na ikhemikhali, kukho amanyathelo aliqela abandakanyekayo kuvavanyo lomngcipheko, kubandakanya nokuqokelela ulwazi malunga nokuvezwa kwabantu, ukuze amanqanaba avelisa ingozi kuluntu olunye okanye uhlobo oluthile lwesilwanyana unokuthelekiswa namanqanaba okuvezwa okuqhelekileyo," ababhali babhala.

“Nangona kunjalo, ngaphambili besibonisile ukuba idatha ekubonakalisweni kwabantu kubasebenzi nakubantu ngokubanzi inqongophele. Zininzi ezinye izithuba kulwazi ezikhoyo malunga nale mveliso, umzekelo, iziphumo kwi-genotoxicity yayo ebantwini isikelwe umda. Ingxoxo eqhubekayo malunga nefuthe lokuvezwa kwe-glyphosate yenza ukuba ukusekwa kwinqanaba lokuvezwa kuluntu ngokubanzi kube ngumcimbi oxinzelelweyo wezempilo, ngakumbi kwabona basemngciphekweni. ”

Ababhali bathi ukubekwa kweliso kumanqanaba e-urinary glyphosate kufuneka kuqhutywe kubemi ngokubanzi.

"Siyaqhubeka nokucebisa ukuba ukubandakanywa kwe-glyphosate njengokubonakaliswa okulinganiselweyo kwizifundo ezimele ilizwe njenge-National Health and Nutrition Examination Survey kuyakuvumela ukuqonda okungcono ngemingcipheko enokubangelwa yi-glyphosate kwaye ivumele ukubekwa esweni okungcono kwabo kunokwenzeka babhentswe kwaye abo basemngciphekweni wokuvezwa, ”babhala.

Iphepha leNqaku leGlyphosate: Umhlaza kunye nezinye iingxaki zeMpilo

ushicilelo Imeyli isabelo Ukufuna

Glyphosate, into eyenziwayo yokubulala ukhula enelungelo elilodwa lomenzi wayo ngo-1974 yiNkampani iMonsanto kwaye ngoku yenziwe yaza yathengiswa ziinkampani ezininzi kumakhulu eemveliso, inxulunyaniswa nomhlaza kunye nezinye iingxaki zempilo. IGlyphosate yaziwa njengeyona nto iphambili kwi-Roundup-branded herbicides, kunye ne-herbicide esetyenziswa kwi "Roundup Ready" yezinto eziphilayo eziguqulweyo (GMOs).

Ukunyamezelana nokubulala intsholongwane lolona hlobo lwe GMO luxhaphakileyo olwenziweyo kwizityalo zokutya, malunga ne-90% yengqolowa kunye ne-94% yeembotyi zesoya e-US ezilungiselelwe ukunyamezela i-herbicides, ngokweedatha ze-USDA. A Ucwaningo lwe-2017 ukufumanisa ukuba ukubonakaliswa kwabantu baseMelika kwi-glyphosate kunyuke malunga 500 ekhulwini okoko i-Roundup Ready GMO izityalo zaziswa e-US ngo-1996. Nazi ezinye iinyani eziphambili malunga neglyphosate:

Uninzi lweePesticide ezisetyenziswa kakhulu

Ngokutsho NgoFebruwari 2016 isifundo, Iglyphosate yi esetyenziswa kakhulu isibulali zinambuzane: E-US, akukho sibulali zinambuzane sisondeleyo kule ndawo isetyenziswa kakhulu. ” Iziphumo zibandakanya:

  • Abantu baseMelika basebenzise i-1.8 yezigidi zeetoni ze-glyphosate okoko yaqaliswa ngo-1974.
  • Ehlabathini lonke i-9.4 yezigidi zeetoni zekhemikhali ziye zafafazwa kumasimi-anele ukutshiza phantse isiqingatha sepawundi yeRoundup kuyo yonke iakile yomhlaba elinywayo.
  • Ehlabathini jikelele, ukusetyenziswa kwe-glyphosate kuye kwanda phantse kangangezihlandlo ezili-15 okoko kwaziswa izityalo zeRoundup Ready GMO.

Iingxelo ezivela kwizazinzulu nakubanikezeli bezempilo 

Iingxaki zomhlaza

Uncwadi lwezenzululwazi kunye nezigqibo zolawulo ngokubhekisele kwi-glyphosate kunye ne-glyphosate-based herbicides zibonisa ukuxubana kweziphumo, okwenza ukhuseleko lwe-herbicide lube sisifundo esixoxwa kakhulu. 

Kwi-2015, i I-Arhente yeHlabathi yezeMpilo yoPhando ngomhlaza (IARC) I-glyphosate echaziweyo njenge-mhlawumbi i-carcinogenic ebantwini”Emva kokuphonononga iminyaka yophando kunye nophengululo olwenziwe ngontanga. Iqela lezenzululwazi zamazwe aphesheya lafumanisa ukuba kukho umbutho othile phakathi kwe-glyphosate kunye ne-non-Hodgkin lymphoma.

Iiarhente zase-US: Ngexesha lokuhlelwa kwe-IARC, i-Arhente yokuKhuselwa kokusiNgqongileyo (i-EPA) yayiqhuba uphononongo lobhaliso. IKomiti yokuHlola uMhlaza ye-EPA (CARC) ikhuphe ingxelo ngoSeptemba 2016 Ukuqukumbela ukuba i-glyphosate "ayinakulindeleka ukuba ibe ngumhlaza ebantwini" ngeedosi ezifanelekileyo kwimpilo yabantu. NgeyoMnga yowama-2016, i-EPA yabiza iSigqeba esiCebisayo ngezeNzululwazi ukuze siqwalasele ingxelo; amalungu ebekhona yahlulwe kuvavanyo lomsebenzi we-EPA, ngokufumanisa ukuba i-EPA yenze impazamo kwindlela eluvavanye ngayo uphando oluthile. Ukongeza, iOfisi ye-EPA yoPhando noPhuhliso igqibe ekubeni iOfisi yeNkqubo ye-Pesticide ye-EPA ayilandelwa iiprothokholi ezifanelekileyo kuvavanyo lwayo lwe-glyphosate, wathi ubungqina bungathathwa njengexhasa ubungqina “obunokubakho” be-carcinogenic okanye obucebisayo “bokuhlelwa kwe-carcinogenicity. Nangona kunjalo i-EPA ikhuphe ingxelo eyilwayo kwi-glyphosate ngoDisemba 2017 eqhubeka nokubamba ukuba imichiza ayinakuba ngumhlaza. Ngo-Epreli 2019, i-EPA iphinde yaqinisekisa ukuma kwayo loo glyphosate ayibeki mngcipheko kwimpilo yoluntu. Kodwa kwangoko kwakuloo nyanga, i-Arhente yase-US yeZinto ezinobungozi kunye neRegistry yeZifo (i-ATSDR) ixele ukuba kukho amakhonkco phakathi kwe-glyphosate kunye nomhlaza. Ngokwe- Idrafti yengxelo evela kwi-ATSDR, "Uphononongo oluninzi luchaze umngcipheko omkhulu kunomnye kwimibutho phakathi kokuvezwa kwe-glyphosate kunye nomngcipheko we-non-Hodgkin's lymphoma okanye i-myeloma emininzi." 

I-EPA ikhuphe i Isigqibo sokuHlola okwethutyana ngoJanuwari 2020 ngolwazi oluhlaziyiweyo malunga nokuma kwayo kwi-glyphosate. 

Udibano lwaseyurophu: The IGunya loKhuseleko loKutya laseYurophu kwaye i I-arhente yeekhemikhali yaseYurophu bathe i-glyphosate ayinakubangelwa yi-carcinogenic ebantwini. A Ingxelo kaMatshi 2017 ngamaqela okusingqongileyo kunye nabathengi bathi abalawuli baxhomekeke ngokungafanelekanga kuphando olwalujolise kwaye lwenziwa ngumzi mveliso weekhemikhali. A Ucwaningo lwe-2019 ifumanise ukuba i-Federal Institute yaseJamani yoVavanyo loMngcipheko kwi-glyphosate, engafumananga mngcipheko womhlaza, ibandakanya amacandelo okubhaliweyo echazwe kwizifundo zeMonsanto. NgoFebruwari 2020, kwavela iingxelo zokuba izifundo ezingama-24 ezingeniswe kubalawuli baseJamani ukungqina ukhuseleko lwe-glyphosate zavela kwilabhoratri enkulu yaseJamani utyholwa ngobuqhetseba nokunye okungalunganga.

Intlanganiso edibeneyo ye-WHO / FAO kwiiNtsalela zeziBulala-zinambuzane misele Kwi-2016 ukuba i-glyphosate yayingenakulindeleka ukuba ibangele umngcipheko we-carcinogenic ebantwini ekuvezweni kukutya, kodwa oku kufunyaniswa kwaphazanyiswa ukugqubana kwemidla inkxalabo emva kokuvela ukuba usihlalo kunye nosihlalo weqela bakwizikhundla zobunkokheli kunye IZiko lezeNzululwazi ngezoBomi leHlabathi, iqela elixhaswe ngemali yinxalenye yeMonsanto kunye nenye yemibutho yokucela inkxaso.

California OEHHA: Ngomhla wamashumi amabini anesibhozo ku-Matshi ngo-28, iOfisi yeArhente yoKhuseleko lwezeNdalo eCalifornia yoVavanyo lweNgozi yezeMpilo yokusiNgqongileyo yaqinisekisa ukuba iya kuba njalo yongeza i-glyphosate Isindululo saseCalifornia uluhlu lwama-65 lweekhemikhali ezaziwa ngokubangela umhlaza. UMonsanto wamangalela ukuvimba isenzo kodwa ityala lachithwa. Kwityala elahlukileyo, inkundla yafumanisa ukuba iCalifornia ayinakufuna izilumkiso zomhlaza kwiimveliso eziqukethe i-glyphosate. Nge-12 kaJuni ka-2018, iNkundla yeSithili sase-US yasikhaba isicelo se-Attorney General sase-California sokuba inkundla iphinde isijonge isigqibo. Inkundla yafumanisa ukuba iCalifornia inokufuna kuphela intetho yentengiso echaze "ulwazi oluyinyani nolungenakuphikiswa," kwaye inzululwazi ejikeleze i-glyphosate carcinogenicity ayiboniswanga.

Isifundo seMpilo yezoLimo: Isifundo sexesha elide esixhaswa ngurhulumente wase-US esineqela elixhasayo ngeentsapho zasezifama e-Iowa nase-North Carolina khange lifumane nxu lumano phakathi kokusetyenziswa kwe-glyphosate kunye ne-non-Hodgkin lymphoma, kodwa abaphandi baxela ukuba "phakathi kwezicelo ezikwindawo ephezulu yokuvezwa, bekukho umngcipheko okhulayo we-myeloid leukemia (AML) xa kuthelekiswa nabantu abangazange basebenzise… ”Olona hlaziyo lupapashiweyo kutsha nje kuphando yenziwa esidlangalaleni ngasekupheleni kuka-2017.

Izifundo zamva nje zokudibanisa i-glyphosate kunye nomhlaza kunye nezinye iingxaki zempilo

Amacala omhlaza

Ngaphezulu kwabantu abangama-42,000 abafake isimangalo ngokuchasene neNkampani iMonsanto (ngoku eyiBayer) betyhola ukuba ukubhencwa kwi-Roundup herbicide kubangele bona okanye abo babathandayo ukuba baphuhlise i-non-Hodgkin lymphoma (NHL), kwaye iMonsanto yagquma ubungozi. Njengengxenye yenkqubo yokufumanisa, iMonsanto kuye kwafuneka iguqulwe kwizigidi zamaphepha eerekhodi zangaphakathi. Singo ukuthumela la maPhepha eMonsanto njengoko ezifumaneka. Ukufumana iindaba kunye neengcebiso malunga nomthetho oqhubekayo, jonga uCarey Gillam's Umjongi weTrial Rounder. Izilingo ezintathu zokuqala zaye zaphelela kumabhaso amakhulu kubamangali ngenxa yoxanduva kunye nomonakalo, ngamajaji agweba ukuba umbulali wokhula kaMonsanto waba negalelo elibangela ukuba baphuhlise i-NHL. I-Bayer ibhengeza isigwebo. 

Impembelelo yeMonsanto kuphando: Ngo-Matshi 2017, ijaji yenkundla yomanyano yavula amanye amaxwebhu angaphakathi eMonsanto iphakamise imibuzo emitsha malunga nefuthe likaMonsanto kwinkqubo ye-EPA nangabalawuli bophando abathembele kuyo. Amaxwebhu abonisa ukuba amabango akudala kaMonsanto malunga nokhuseleko lwe-glyphosate kunye neRoundup ungaxhomekeki kwisayensi elungileyo njengoko inkampani iqinisekisa, kodwa ivulwe iinzame zokusebenzisa inzululwazi

Ukuchithwa: omnye umthombo wokuvezwa kokutya 

Abanye abalimi basebenzisa i-glyphosate kwizityalo ezingezo-GMO ezifana nengqolowa, irhasi, i-oats, kunye neelentile ukomisa isityalo ngaphambi kokuvuna ukuze kukhawuleziswe isivuno. Lo mkhuba, eyaziwa ngokuba yi-desiccation, inokuba ngumthombo obalulekileyo wokuvezwa kokutya kwi-glyphosate.

IGlyphosate ekutyeni: I-US irhuqa iinyawo zayo kuvavanyo

I-USDA ithe cwaka yalahla isicwangciso sokuqala ukuvavanya ukutya kwentsalela ye-glyphosate ngo-2017. Amaxwebhu e-arhente angaphakathi afunyenwe yi-US Right to Know abonisa ukuba i-arhente icwangcise ukuqala ukuvavanya ngaphezulu kweesampulu ezingama-300 zesiraphu yengqolowa ye-glyphosate ngo-Epreli ka-2017. Iarhente ibulale iprojekthi ngaphambi kokuba iqale. I-US Food and Drug Administration yaqala inkqubo yovavanyo encinci ngo-2016, kodwa iinzame zazigcwele impikiswano kunye nobunzima bangaphakathi kwaye inkqubo yayi kumiswa ngoSeptemba 2016. Zombini ezi arhente zineenkqubo ezivavanya ukutya rhoqo ngonyaka kwintsalela yokubulala izitshabalalisi kodwa zombini ziye zayeka ukuvavanywa kwe-glyphosate.

Phambi kokumiswa, kwafunyanwa ikhemesti enye ye-FDA Amanqanaba othusayo e-glyphosate Kwiisampulu ezininzi zobusi baseMelika, amanqanaba awayengekho semthethweni ngenxa yokuba kungakhange kubekho manqanaba avumelekileyo enzelwe ubusi yi-EPA. Nalu uphinda lweendaba malunga ne-glyphosate efumaneka kukutya:
