Ishidi Leqiniso LeGlyphosate: Umdlavuza Nokunye Ukukhathazeka Kwezempilo

Phrinta imeyili Ungahlukıselana Ephathwayo

I-Glyphosate, i-herbicide yokwenziwa enelungelo lobunikazi ngonyaka we-1974 yiMonsanto Company futhi manje eyenziwe futhi ithengiswa yizinkampani eziningi emikhiqizweni engamakhulu, ihlotshaniswa nomdlavuza nokunye ukukhathazeka ngempilo. IGlyphosate yaziwa kakhulu njengesithako esisebenzayo kuma-herbicides anohlobo lwe-Roundup, kanye ne-herbicide esetshenziswa ne-"Roundup Ready" yezinto eziphilayo eziguqulwe izakhi zofuzo (GMOs).

Ukubekezelelana kwe-Herbicide kuyisici esande kakhulu se-GMO esenziwe izitshalo zokudla, kanti amanye ama-90% ommbila nama-94% kabhontshisi wase-US enzelwe ukubekezelela ukubulala ukhula, ngokusho kwedatha ye-USDA. A Ucwaningo lwe-2017 ithole ukuthi ukuvezwa kwabantu baseMelika ku-glyphosate kukhuphuke cishe 500 amaphesenti selokhu kwethulwa izitshalo ze-Roundup Ready GMO e-US ngo-1996. Nawa amanye amaqiniso abalulekile nge-glyphosate:

I-Pesticide Esetshenziswa Kakhulu

Ngokombiko othile NgoFebhuwari 2016 isifundo, i-glyphosate yiyona isibulala-zinambuzane esisetshenziswa kakhulu: "E-US, asikho isibulala-zinambuzane esiseduze kakhulu nokusetshenziswa okunamandla nokusakazeke kangaka." Okutholakele kufaka phakathi:

  • AbaseMelika basebenzise amathani ayi-1.8 wezigidi ze-glyphosate selokhu yethulwa ngo-1974.
  • Emhlabeni wonke kufuthwe amathani ayizigidi eziyi-9.4 amakhemikhali emasimini - anele ukufafaza cishe isigamu sephawundi seRoundup kuwo wonke amahektare alinywayo emhlabeni.
  • Emhlabeni jikelele, ukusetshenziswa kwe-glyphosate kukhuphuke cishe izikhathi eziyi-15 selokhu kwethulwe izitshalo zeRoundup Ready GMO.

Izitatimende ezivela kososayensi nabahlinzeki bokunakekelwa kwempilo 

Ukukhathazeka Ngomdlavuza

Imibhalo yesayensi kanye neziphetho zokulawula maqondana ne-glyphosate kanye ne-glyphosate-based herbicides ikhombisa ukuxubana kokutholakele, okwenza ukuphepha kwe-herbicide kube yindaba ephikisanayo. 

Ngo 2015, the I-International Health Organization's International Agency for Research on Cancer (IARC) i-glyphosate ehlukanisiwe njengo-mhlawumbe i-carcinogenic kubantu”Ngemuva kokubukeza iminyaka yocwaningo lwesayensi olushicilelwe nolubuyekezwa ontanga. Ithimba lososayensi bamazwe omhlaba lithole ukuthi kukhona ukuhlangana okuthile phakathi kwe-glyphosate ne-non-Hodgkin lymphoma.

Izinhlangano ze-US: Ngesikhathi sokuhlukaniswa kwe-IARC, i-Environmental Protection Agency (EPA) yayiqhuba ukubuyekeza ukubhalisa. IKomidi Lokubuyekeza Umdlavuza we-EPA (CARC) ukhiphe umbiko ngoSepthemba 2016 siphetha ngokuthi i-glyphosate "bekungeke kwenzeke ukuthi ibe yi-carcinogenic kubantu" ngemithamo efanele impilo yomuntu. NgoZibandlela wezi-2016, i-EPA yabiza iSigungu Sabeluleki Besayensi ukuze sibuyekeze lo mbiko; amalungu ayekhona ihlukaniswe ekuhloleni kwabo umsebenzi we-EPA, abanye bathola ukuthi i-EPA yenze iphutha ekutheni iluhlole kanjani ucwaningo oluthile. Ngokwengeziwe, iHhovisi Lezokucwaninga Nentuthuko le-EPA linqume ukuthi iHhovisi Lezinhlelo Zezibulala-zinambuzane ze-EPA ayilandelwa imigomo efanele ekuhloleni kwayo i-glyphosate, futhi yathi ubufakazi bungathathwa njengobusekela ubufakazi “obungenzeka” bomdlavuza noma “obusikisela” bokwehlukaniswa kwe-carcinogenicity. Noma kunjalo i-EPA ukhiphe umbiko osalungiswa ku-glyphosate ngoDisemba 2017 eqhubeka nokubamba ukuthi ikhemikhali akunakwenzeka ukuthi libe yi-carcinogenic. Ngo-Ephreli 2019, i-EPA kwaqinisekisa isikhundla sayo leyo glyphosate ayibeki bungozi empilweni yomphakathi. Kepha ekuqaleni kwenyanga efanayo, i-US Agency for Toxic Substances and Registry Registry (ATSDR) ibike ukuthi kunokuxhumana phakathi kwe-glyphosate nomdlavuza. Ngokusho kwe- umbiko wokusalungiswa ovela ku-ATSDR, "Ucwaningo oluningi lubike izilinganiso zobungozi ezinkulu kunezinye zezinhlangano eziphakathi kokuchayeka kwe-glyphosate kanye nengozi ye-non-Hodgkin's lymphoma noma i-myeloma eminingi." 

I-EPA ikhiphe i- Isinqumo Sokubukeza Okwesikhashana ngoJanuwari 2020 ngolwazi olusha mayelana nokuma kwalo ku-glyphosate. 

Iyuniyani yase-Europe: The Isiphathimandla Sezokuphepha KwaseYurophu futhi I-European Chemicals Agency bathe i-glyphosate ayinakuba yi-carcinogenic kubantu. A Umbiko ka-Mashi 2017 ngamaqembu ezemvelo nawabathengi athi abalawuli bathembele ngokungafanele ocwaningweni olwaluqondiswa futhi lusetshenziswa imboni yamakhemikhali. A Ucwaningo lwe-2019 ithole ukuthi umbiko weFederal Institute for Risk Assessment waseJalimane ngeglyphosate, ongatholanga ubungozi bomdlavuza, ubufaka phakathi izingxenye zombhalo kukhishwe izifundo zeMonsanto. NgoFebhuwari 2020, kwavela imibiko yokuthi izifundo zesayensi ezingama-24 ezithunyelwe kubalawuli baseJalimane ukufakazela ukuphepha kwe-glyphosate zaqhamuka elabhorethri enkulu yaseJalimane osolwa ngokukhwabanisa nokunye okungalungile.

Umhlangano ohlangene we-WHO / FAO wezinsalela ze-Pesticide kunqunywe ngo-2016 ukuthi i-glyphosate yayingenakwenzeka ukufaka ingozi ye-carcinogenic kubantu kusukela ekuvezweni ngokudla, kepha lokhu kutholakala kungcoliswe ngu ukushayisana kwezintshisekelo ukukhathazeka ngemuva kokuvela ukuthi usihlalo kanye nosihlalo weqembu nabo babephethe izikhundla zobuholi ne I-International Life Sciences Institute, iqembu elixhaswe ngokwengxenye yiMonsanto nenye yezinhlangano zalo zokunxenxa.

California OEHHA: Ngo-Mashi 28, 2017, iHhovisi Lezokuvikelwa Kwezemvelo e-California Environmental Protection Agency laqinisekisa ukuthi kuzokwenzeka engeza i-glyphosate ohlwini lwe-Proposition 65 lwaseCalifornia lwamakhemikhali aziwa ukudala umdlavuza. UMonsanto wamangalela ukuvimba lesi senzo kodwa icala lachithwa. Kwelinye icala, inkantolo ithole ukuthi iCalifornia ayinakudinga izexwayiso zomdlavuza ngemikhiqizo equkethe i-glyphosate. NgoJuni 12, 2018, iNkantolo yesiFunda e-US yasenqaba isicelo se-California Attorney General sokuthi inkantolo isiphinde icubungule lesi sinqumo. Inkantolo ithole ukuthi iCalifornia ingadinga kuphela inkulumo yezentengiso edalula "imininingwane eyiqiniso futhi engenakuphikiswa," futhi nesayensi ezungeze i-glyphosate carcinogenicity ayizange itholakale.

Isifundo Sezempilo Kwezolimo: Ucwaningo lukahulumeni wase-US olwalusekelwa isikhathi eside oluzoxhaswa yimindeni yasepulazini e-Iowa naseNyakatho Carolina alutholanga ukuxhumana phakathi kokusetshenziswa kwe-glyphosate kanye ne-non-Hodgkin lymphoma, kodwa abacwaningi babika ukuthi “phakathi kwabafaka izicelo ku-quartile yokuvezwa okuphezulu kakhulu, kwakukhona ingozi eyengeziwe ye-acute myeloid leukemia (AML) uma iqhathaniswa nabangakaze basebenzise… ”Ukubuyekezwa kwakamuva kakhulu okushicilelwe ocwaningweni yenziwa umphakathi ngasekupheleni kuka-2017.

Izifundo zakamuva ezixhumanisa i-glyphosate nomdlavuza nokunye ukukhathazeka ngempilo 

Cancer

Ukuphazanyiswa kwe-Endocrine, ukukhathazeka nokuzala 

Isifo sesibindi 

  • Ucwaningo lwango-2017 luhambisana nokuchayeka okungapheli, okunezinga eliphansi kakhulu le-glyphosate isifo sesibindi esingenawo utshwala kumagundane. Ngokusho kwabaphenyi, imiphumela "isho ukuthi ukusetshenziswa okungapheli kwamazinga aphansi kakhulu ekwakhiweni kwe-GBH (Roundup), ezindaweni ezivumelekile ezilingana ne-glyphosate, kuhlotshaniswa nokuguqulwa okuphawulekayo kwe-proteome yesibindi ne-metabolism," ama-biomarkers we-NAFLD.

Ukuphazanyiswa kweMicrobiome 

  • November 2020 iphepha ku-Journal of Materials Hazardous ibika ukuthi cishe amaphesenti angama-54 ezinhlobo ezisenkabeni ye-gut gut microbiome "angazwela" ku-glyphosate. Nge "ingxenye enkulu" yamabhaktheriya esiswini i-microbiome esengozini ye-glyphosate, ukutholwa kwe-glyphosate "kungathinta kakhulu ukwakheka kwe-gut microbiome yomuntu," kusho abalobi ephepheni labo. 
  • A 2020 ukubuyekezwa kwezincwadi kwemiphumela ye-glyphosate ku-gut microbiome iphetha ngokuthi, "izinsalela ze-glyphosate ekudleni zingadala i-dysbiosis, uma kubhekwa ukuthi amagciwane angosomathuba amelana kakhulu ne-glyphosate uma kuqhathaniswa nama-bacteria asebenzayo." Leli phephandaba liyaqhubeka, “IGlyphosate ingase ibe yisici esibucayi kwezemvelo ku-etiology yezifo eziningana ezihambisana ne-dysbiosis, kufaka phakathi isifo se-celiac, isifo samathumbu esivuthayo kanye nesifo samathumbu esivele sicasuke. Ukuvezwa kweGlyphosate nakho kungaba nemiphumela empilweni yengqondo, kufaka phakathi ukukhathazeka nokudangala, ngokushintsha kwesisu segciwane. ”
  • Ucwaningo lwama-rat lwango-2018 olwenziwe yiRamazzini Institute lubike ukuthi ukuvezwa kwamazinga aphansi ku-Roundup emazingeni athathwa njengaphephe kakhulu kushintshe i-gut microbiota kwamanye amazinyane egundane.
  • Olunye ucwaningo lwango-2018 lubike ukuthi amazinga aphezulu e-glyphosate afakwa kumagundane aphazamisa i-gut microbiota futhi kubangele ukukhathazeka nokuziphatha okufana nokudana.

Amacala omdlavuza

Bangaphezu kuka-42,000 abantu abafake isimangalo eMonsanto Company (manje eyiBayer) bethi ukutholakala kwe-Roundup herbicide kubangele bona noma abathandekayo babo ukuba bahlakulele i-non-Hodgkin lymphoma (NHL), nokuthi iMonsanto yamboza izingozi. Njengengxenye yenqubo yokutholwa, iMonsanto kudingeke ukuthi ivule izigidi zamakhasi amarekhodi angaphakathi. Singa ukuthumela la Maphepha eMonsanto njengoba ezotholakala. Ukuze uthole izindaba namathiphu mayelana nomthetho oqhubekayo, bheka uCarey Gillam's I-Roundup Trial Tracker. Izilingo ezintathu zokuqala zaphetha ngemiklomelo emikhulu kwabamangali ngesikweletu nomonakalo, amajaji athatha isinqumo sokuthi umbulali wokhula kaMonsanto waba nomthelela omkhulu ekubangeleni ukuthi bathuthukise i-NHL. IBayer iyasidlulisa lesi sinqumo. 

Ithonya leMonsanto ocwaningweni: Ngo-Mashi 2017, ijaji lenkantolo yombuso livule imibhalo yangaphakathi yeMonsanto leyo kwaphakamisa imibuzo emisha mayelana nethonya likaMonsanto kunqubo ye-EPA nangabalawuli bocwaningo abathembele kulo. Le mibhalo iphakamisa ukuthi izimangalo zikaMonsanto ezimi isikhathi eside mayelana nokuphepha kwe-glyphosate ne-Roundup musa ukuthembela kwisayensi ezwakalayo njengoba inkampani iqinisekisa, kepha ivuliwe imizamo yokusebenzisa isayensi

Imininingwane engaphezulu mayelana nokuphazamiseka kwesayensi:

Ososayensi baseSri Lankan banikeze umklomelo wenkululeko we-AAAS wocwaningo lwezifo zezinso

I-AAAS inikeze ososayensi ababili baseSri Lankan, uDkt. UChanna Jayasumana noSarath Gunatilake, the Umklomelo we-2019 Wenkululeko Yesayensi Nokuzibophezela ngomsebenzi wabo "wokuphenya ukuxhumana okungenzeka phakathi kwe-glyphosate nesifo esingapheliyo sezinso ngaphansi kwezimo eziyinselele." Ososayensi babike ukuthi i-glyphosate idlala indima enkulu ekuhambiseni izinsimbi ezisindayo ezinso zalabo abaphuza amanzi angcolile, okuholela emazingeni aphezulu esifo esingapheliyo sezinso emiphakathini yokulima. Bona amaphepha ku-  I-SpringerPlus (2015), I-BMC Nephrology (2015), Health Environmental (2015), Ijenali Yomhlaba Wonke Wocwaningo Lwezemvelo kanye Nezempilo Yomphakathi (2014). Umklomelo we-AAAS ubukade ukhona imisiwe phakathi komkhankaso ophikisayo wokuphikisana wabalingani bemboni yezibulala-zinambuzane ukubukela phansi umsebenzi wososayensi. Ngemuva kokubuyekezwa, i-AAAS ubuyisele umklomelo

Ukwehliswa: omunye umthombo wokuchayeka ekudleni 

Abanye abalimi basebenzisa i-glyphosate ezitshalweni ezingezona eze-GMO ezifana nokolweni, ibhali, i-oats, nama-lentile ukomisa isivuno ngaphambi kokuvuna ukuze kusheshiswe isivuno. Lo mkhuba, eyaziwa ngokuthi i-desiccation, kungaba ngumthombo obalulekile wokuchayeka ekudleni kwe-glyphosate.

IGlyphosate ekudleni: I-US idonsa izinyawo zayo ekuhlolweni

I-USDA yehlisa buthule uhlelo lokuqala ukuhlola ukudla kwezinsalela ze-glyphosate ngo-2017. Imibhalo ye-ejensi yangaphakathi etholwe yi-US Right to Know ikhombisa ukuthi i-ejensi yayihlele ukuqala ukuhlola amasampula angaphezu kuka-300 wesiraphu yommbila i-glyphosate ngo-Ephreli 2017. Kodwa i-ejensi yabulala iphrojekthi ngaphambi kokuthi iqale. Ukuphathwa Kwezokudla Nezidakamizwa e-US kwaqala uhlelo lokuhlola olunomkhawulo ngo-2016, kodwa umzamo wawugcwele impikiswano nobunzima bangaphakathi kanti uhlelo lwalunjalo yamiswa ngoSepthemba 2016. Womabili la ma-ejensi anezinhlelo ezivivinya minyaka yonke ukudla kwezinsalela ze-pesticides kodwa zombili ziye zeqa ukuhlolwa kwe-glyphosate.

Ngaphambi kokumiswa, kutholakale isazi samakhemikhali esisodwa se-FDA amazinga ashaqisayo e-glyphosate kumasampula amaningi oju lwase-US, amazinga ayengavumelekile ngokomthetho ngoba awekho amazinga avunyelwe ukusetshenziselwa uju yi-EPA. Nayi impinda yezindaba mayelana ne-glyphosate etholakala ekudleni:

Ama-pesticides ekudleni kwethu: Ikuphi idatha yokuphepha?

Idatha ye-USDA yango-2016 ikhombisa amazinga atholakala ngezibulala-zinambuzane kokungu-85% kokudla okungaphezulu kuka-10,000 XNUMX okusampuli, konke kusuka kumakhowe kuya kumagilebhisi kuya kubhontshisi oluhlaza. Uhulumeni uthi zincane izingozi zezempilo, kepha abanye ososayensi bathi akukho lwazi oluncane lokusekela leso simangalo. Bona “Amakhemikhali ekudleni kwethu: Uma "kuphephile" kungahle kungaphephi ngempela: Ukuhlolwa kwesayensi kwensalela ye-pesticin ekudleni kuyakhula; ukuvikelwa kokulawula kubuzwa, ”NguCarey Gillam (11/2018).
