Olakwa: Chifukwa chiyani oats athu ali ndi chlormequat?

Chlormequat ndi odziwika bwinochowongolera kukula kwa mbewuamagwiritsidwa ntchito kulimbikitsa kapangidwe ka mbewu ndikuthandizira kukolola. Koma mankhwalawo tsopano akuwunikiridwa kwatsopano m'makampani azakudya aku US kutsatira kupezeka kwake mosayembekezeka komanso kufalikira mu masheya a oat ku US. Ngakhale mbewuyo idaletsedwa kudyedwa ku United States, chlormequat yapezeka muzinthu zingapo za oat zomwe zitha kugulidwa m'dziko lonselo.
Kuchuluka kwa chlormequat kudawululidwa makamaka kudzera mu kafukufuku ndi kafukufuku wopangidwa ndi Environmental Working Group (EWG), yomwe, mu kafukufuku waposachedwa wofalitsidwa mu Journal of Exposure Science and Environmental Epidemiology, idapeza kuti milandu isanu chlormequat idapezeka mkodzo wa anayi a iwo. ophunzira anayi. .
Alexis Temkin, katswiri wa za poizoni m’gulu la Environmental Working Group, anasonyeza nkhaŵa ponena za mmene chlormequat ingawononge thanzi la munthu, anati: “Kufala kwa mankhwala ophera tizilombo osaphunzira kwenikweni mwa anthu kumapangitsa kukhala kovuta kuwasamalira. aliyense amadziwa ngakhale kuti adadyedwa. “
Kupezeka kuti milingo ya chlormequat m'zakudya zokhazikika imachokera ku zosazindikirika mpaka 291 μg/kg kwadzetsa mkangano pazathanzi lomwe lingakhalepo kwa ogula, makamaka popeza chlormequat yakhala ikugwirizana ndi zotulukapo zoyipa za ubereki komanso zotsatira zoyipa zaubereki m'maphunziro a nyama. pamavuto akukula kwa fetal.
Ngakhale udindo wa US Environmental Protection Agency (EPA) ndikuti chlormequat imakhala ndi chiopsezo chochepa ikagwiritsidwa ntchito monga momwe ikufunira, kupezeka kwake muzinthu zotchuka za oat monga Cheerios ndi Quaker Oats ndizodetsa nkhawa. Izi zimafuna mwachangu njira yokhazikika komanso yokhazikika yowunika momwe chakudya chimakhalira, komanso kafukufuku wozama wa toxicological ndi miliri kuti awone bwino zomwe zingachitike paumoyo wokhudzana ndi kukhudzidwa kwa chlormequat.
Vuto lalikulu lagona pa njira zowongolera ndi kuyang'anira kagwiritsidwe ntchito ka zowongolera kukula ndi mankhwala ophera tizilombo polima mbewu. Kupezeka kwa chlormequat mu zinthu za oat zapakhomo (ngakhale kuti ndizoletsedwa) kukuwonetsa zolakwika za dongosolo lamasiku ano lowongolera ndikuwonetsa kufunikira kokhazikitsa mwamphamvu malamulo omwe alipo komanso mwina kupangidwa kwa malangizo atsopano azaumoyo.
Temkin adatsindika kufunikira kwa malamulo, ponena kuti, "Boma limagwira ntchito yofunika kwambiri pakuwonetsetsa kuti kuwunika moyenera, kufufuza, ndi kuwongolera mankhwala ophera tizilombo. Komabe bungwe la Environmental Protection Agency likupitirizabe kusiya ntchito yake yoteteza ana ku mankhwala omwe ali m'zakudya zawo. Udindo pa ngozi zomwe zingachitike. ” kuopsa kwa thanzi la mankhwala oopsa monga chlormequat.”
Izi zikuwonetsanso kufunikira kwa chidziwitso cha ogula komanso ntchito yomwe imagwira pakulimbikitsa thanzi la anthu. Ogula odziwitsidwa okhudzidwa ndi zoopsa zomwe zingachitike paumoyo wokhudzana ndi chlormequat akutembenukira kuzinthu za oat ngati njira yodzitetezera kuti achepetse kukhudzidwa ndi izi ndi mankhwala ena omwe ali ndi nkhawa. Kusintha kumeneku sikungowonetsa kukhazikika kwaumoyo, komanso kukuwonetsa kufunikira kowonekera bwino komanso chitetezo pakupanga chakudya.
Kupezeka kwa chlormequat ku US oat supply ndi nkhani yochuluka yokhudzana ndi malamulo, thanzi la anthu, ndi chitetezo cha ogula. Kuthana bwino ndi vutoli kumafuna mgwirizano pakati pa mabungwe a boma, ntchito zaulimi ndi anthu kuti awonetsetse kuti chakudya chili chotetezeka komanso chopanda matenda.
Mu Epulo 2023, poyankha pempho la 2019 lopangidwa ndi wopanga chlormequat Taminco, Biden's Environmental Protection Agency ikufuna kulola kugwiritsa ntchito chlormequat mu balere waku US, oats, triticale ndi tirigu kwa nthawi yoyamba, koma EWG idatsutsa dongosololi. Malamulo omwe aperekedwawo sanamalizidwebe.
Pomwe kafukufuku akupitiliza kuwulula zomwe zingachitike chifukwa cha chlormequat ndi mankhwala ena ofanana, kupanga njira zonse zotetezera thanzi la ogula popanda kusokoneza kukhulupirika ndi kukhazikika kwa njira zopangira chakudya ziyenera kukhala patsogolo.
Food Institute yakhala yoyamba "yoyimitsa imodzi" kwa oyang'anira mafakitale azakudya kwazaka zopitilira 90, ikupereka zidziwitso zomwe zingatheke kudzera muzosintha zamaimelo zatsiku ndi tsiku, malipoti a Food Institute a sabata ndi laibulale yayikulu yofufuza pa intaneti. Njira zathu zosonkhanitsira zidziwitso zimapitilira "kusaka mawu osakira".
