Chlormequat inozivikanwa zvikurumutariri wekukura kwezvirimwainoshandiswa kusimbisa chimiro chezvirimwa uye kuita kuti kukohwewa kuve nyore. Asi kemikari iyi ikozvino iri kuongororwa patsva muindasitiri yechikafu yeUS mushure mekuwanikwa kwayo kusingatarisirwi uye kwakapararira mumasheya eoat ekuUS. Kunyangwe chirimwa ichi chakarambidzwa kudyiwa muUnited States, chlormequat yakawanikwa mune zvigadzirwa zveoat zvakawanda zviripo kuti zvitengeswe munyika yese.
Kuwanda kwechlormequat kwakaratidzwa zvakanyanya kuburikidza nekutsvagisa nekuferefeta kwakaitwa neEnvironmental Working Group (EWG), iyo, muongororo yakabudiswa muJournal of Exposure Science and Environmental Epidemiology, yakawana kuti muzviitiko zvishanu chlormequat yakaonekwa mumienzaniso yeweti yevana vavo.
Alexis Temkin, nyanzvi yezvipfuyo yeEnvironmental Working Group, akaratidza kunetseka nezvemigumisiro inogona kuitika pahutano yechlormequat, achiti: "Kushandiswa kwakapararira kwemushonga uyu wezvipembenene usinganyanyi kudzidzwa muvanhu kunoita kuti zviome kuushandisa. Chero ani zvake anoziva kuti wakadyiwa."
Kuwanikwa kwekuti huwandu hwechlormequat muzvikafu zvemazuva ano hunotangira pahusingaonekwe kusvika pa291 μg/kg kwakakonzera gakava pamusoro pemigumisiro inogona kuitika pahutano kune vatengi, kunyanya sezvo chlormequat yakabatana nemigumisiro yakaipa yekubereka uye mhedzisiro yakaipa yekubereka muzvidzidzo zvemhuka.
Kunyange hazvo maonero eUS Environmental Protection Agency (EPA) ari ekuti chlormequat haina njodzi yakawanda kana ikashandiswa sezvinokurudzirwa, kuvapo kwayo muzvigadzirwa zveoat zvakakurumbira zvakaita seCheerios neQuaker Oats kunonetsa. Mamiriro ezvinhu aya anoda nekukurumidza nzira yakaoma uye yakazara yekutarisa kuwanikwa kwechikafu, pamwe nezvidzidzo zvakadzama zvechepfu nezvirwere kuti vaongorore zvakakwana njodzi dzinogona kuitika pahutano dzine chekuita nekusangana nechlormequat.
Dambudziko guru riri muhurongwa hwekutonga uye kutarisirwa kwekushandiswa kwemishonga inodzora kukura nemishonga yezvipembenene mukurima zvirimwa. Kuwanikwa kwechlormequat mumafuta eat emumba (pasinei nekuti yakarambidzwa) kunoratidza zvikanganiso zvehurongwa hwemitemo yanhasi uye kunoratidza kudiwa kwekusimbiswa kwakasimba kwemitemo iripo pamwe nekuvandudzwa kwemitemo mitsva yehutano hweveruzhinji.
Temkin akasimbisa kukosha kwemutemo, achiti, "Hurumende yemubatanidzwa inoita basa rakakosha mukuona kuti kuchengetedzwa, kutsvagurudza, uye kudzorwa kwemishonga inouraya zvipembenene kwakakodzera kwakakodzera. Asi Environmental Protection Agency inoramba ichisiya basa rayo rekudzivirira vana kubva kumakemikari ari muchikafu chavo. Mutoro wenjodzi dzinogona kuitika." njodzi dzehutano dzinobva kumakemikari ane chepfu akadai sechlormequat.
Mamiriro ezvinhu aya anoratidzawo kukosha kwekuziva vatengi nezvebasa ravanoita mukutsigira hutano hweveruzhinji. Vatengi vane ruzivo vanonetseka nezvenjodzi dzinogona kuitika dzehutano dzine chekuita nechlormequat vari kuramba vachitendeukira kuzvigadzirwa zveoat zve organic senzira yekudzivirira kuderedza kusangana neizvi nemamwe makemikari ane chekuita nazvo. Kuchinja uku hakungoratidzi chete nzira yekugadzirira hutano, asiwo kunoratidza kudiwa kukuru kwekujeka uye kuchengetedzeka mumabasa ekugadzira chikafu.
Kuwanikwa kwechlormequat muhuwandu hweoat muUS inyaya ine mativi akawanda inosanganisira mitemo, hutano hwevanhu, uye kuchengetedzwa kwevatengi. Kugadzirisa dambudziko iri zvinobudirira kunoda kushanda pamwe chete pakati pemasangano ehurumende, vezvekurima neveruzhinji kuti vave nechokwadi chekuti chikafu chinopa chikafu chakachengeteka uye chisina kusvibiswa.
Muna Kubvumbi 2023, vachipindura chikumbiro chakaitwa muna 2019 nemugadziri wechlormequat Taminco, Biden's Environmental Protection Agency yakakurudzira kuti chlormequat ishandiswe mubhari, oats, triticale negorosi rekuUS kekutanga, asi EWG yakapikisa chirongwa ichi. Mitemo yakarongwa haisati yapedziswa.
Sezvo tsvakurudzo ichiramba ichiratidza migumisiro inogona kuitika yechlormequat nemamwe makemikari akafanana, kuumbwa kwenzira dzakakwana dzekuchengetedza hutano hwevatengi pasina kukanganisa kuvimbika uye kugara kwenguva refu kwemaitiro ekugadzira chikafu kunofanirwa kuve chinhu chakakosha.
Food Institute yave iri "nzvimbo imwe chete" yevatungamiriri veindasitiri yezvekudya kwemakore anopfuura makumi mapfumbamwe, ichipa ruzivo runoshanda kuburikidza nekuvandudza maemail zuva nezuva, mishumo yevhiki nevhiki yeFood Institute uye raibhurari yakakura yekutsvagisa online. Nzira dzedu dzekuunganidza ruzivo dzinopfuura "kutsvaga mazwi akakosha" chete.
