Zoyambitsa tirigu: Nchifukwa chiyani oats athu ali ndi chlormequat?

Chlormequat ndi mankhwala odziwika bwinochowongolera kukula kwa zomeraimagwiritsidwa ntchito kulimbitsa kapangidwe ka zomera ndikuthandiza kukolola. Koma mankhwalawo tsopano akufufuzidwanso mumakampani azakudya aku US pambuyo poti apezeka mosayembekezereka komanso mofala m'mafakitale a oat aku US. Ngakhale kuti mbewuzo zaletsedwa kugwiritsidwa ntchito ku United States, chlormequat yapezeka m'zinthu zingapo za oat zomwe zikupezeka kuti zigulidwe mdziko lonselo.
Kufalikira kwa chlormequat kunawululidwa makamaka kudzera mu kafukufuku ndi kafukufuku wochitidwa ndi Environmental Working Group (EWG), yomwe, mu kafukufuku waposachedwa wofalitsidwa mu Journal of Exposure Science and Environmental Epidemiology, idapeza kuti m'milandu isanu chlormequat idapezeka mu mkodzo wa anthu anayi mwa iwo.
Alexis Temkin, katswiri wa poizoni wa Environmental Working Group, adafotokoza nkhawa yake ndi zotsatira za chlormequat pa thanzi, ponena kuti: "Kugwiritsidwa ntchito kwambiri kwa mankhwala ophera tizilombo omwe sanafufuzidwe bwino mwa anthu kumapangitsa kuti zikhale zovuta kuwasamalira. Aliyense amadziwa kuti adadyedwa."
Kupezeka kuti kuchuluka kwa chlormequat mu zakudya zodziwika bwino kumayambira pa 291 μg/kg kwayambitsa mkangano wokhudza zotsatira za thanzi kwa ogula, makamaka popeza chlormequat yakhala ikugwirizana ndi zotsatira zoyipa zobereka komanso zotsatira zoyipa zobereka m'maphunziro a nyama.
Ngakhale kuti bungwe la US Environmental Protection Agency (EPA) likunena kuti chlormequat imakhala ndi chiopsezo chochepa ikagwiritsidwa ntchito monga momwe akulimbikitsira, kupezeka kwake m'zinthu zodziwika bwino za oat monga Cheerios ndi Quaker Oats n'kodetsa nkhawa. Izi zimafuna mwachangu njira yokhwima komanso yokwanira yowunikira chakudya, komanso maphunziro ozama a poizoni ndi matenda kuti aone bwinobwino zoopsa zomwe zingachitike pa thanzi zomwe zingachitike chifukwa cha chlormequat.
Vuto lalikulu lili m'njira zoyendetsera malamulo ndi kuyang'anira kugwiritsa ntchito mankhwala owongolera kukula ndi mankhwala ophera tizilombo popanga mbewu. Kupezeka kwa chlormequat m'mafuta a oat apakhomo (ngakhale kuti ndi oletsedwa) kukuwonetsa zofooka za dongosolo la malamulo la masiku ano ndipo kukuwonetsa kufunikira kokakamiza malamulo omwe alipo komanso mwina kupanga malangizo atsopano azaumoyo wa anthu.
Temkin anagogomezera kufunika kwa malamulo, nati, "Boma la federal limagwira ntchito yofunika kwambiri poonetsetsa kuti likuyang'anira bwino, kufufuza, komanso kuwongolera mankhwala ophera tizilombo. Komabe, Environmental Protection Agency ikupitirizabe kusiya udindo wake woteteza ana ku mankhwala omwe ali mu chakudya chawo. Udindo wa zoopsa zomwe zingachitike." zoopsa pa thanzi kuchokera ku mankhwala oopsa monga chlormequat.
Mkhalidwewu ukuonetsanso kufunika kwa chidziwitso cha ogula ndi gawo lomwe limagwira pa kulimbikitsa thanzi la anthu. Ogula odziwa bwino ntchito omwe akuda nkhawa ndi zoopsa zomwe zingachitike chifukwa cha chlormequat akugwiritsa ntchito kwambiri zinthu zopangidwa ndi oat zachilengedwe ngati njira yodzitetezera kuti achepetse kukhudzana ndi izi ndi mankhwala ena odetsa nkhawa. Kusintha kumeneku sikungowonetsa njira yodziwira thanzi, komanso kukuwonetsa kufunikira kwakukulu kwa kuwonekera poyera komanso chitetezo pakupanga chakudya.
Kupezeka kwa chlormequat mu oat ku US ndi nkhani yokhudza mbali zambiri zokhudza malamulo, thanzi la anthu, komanso chitetezo cha ogula. Kuti vutoli lithe bwino pamafunika mgwirizano pakati pa mabungwe aboma, gawo la ulimi ndi anthu kuti atsimikizire kuti chakudya chili chotetezeka komanso chopanda kuipitsidwa.
Mu Epulo 2023, poyankha pempho la 2019 lomwe linaperekedwa ndi wopanga chlormequat Taminco, bungwe la Biden loteteza zachilengedwe linapereka lingaliro lolola kugwiritsa ntchito chlormequat mu barele, oats, triticale ndi tirigu ku US koyamba, koma EWG inatsutsa dongosololi. Malamulo omwe aperekedwa sanamalizidwebe.
Pamene kafukufuku akupitiliza kuulula zotsatira zomwe zingachitike chifukwa cha chlormequat ndi mankhwala ena ofanana, kupanga njira zonse zotetezera thanzi la ogula popanda kuwononga umphumphu ndi kukhazikika kwa machitidwe opangira chakudya kuyenera kukhala patsogolo.
Food Institute yakhala "malo amodzi" abwino kwambiri kwa akuluakulu a makampani azakudya kwa zaka zoposa 90, popereka chidziwitso chothandiza kudzera mu imelo yosinthidwa tsiku ndi tsiku, malipoti a sabata iliyonse a Food Institute komanso laibulale yayikulu yofufuzira pa intaneti. Njira zathu zosonkhanitsira chidziwitso zimaposa "kufufuza mawu ofunikira" wamba.
