I-Chlormequat iyaziwa kakhuluumlawuli wokukhula kwezitshaloisetshenziselwa ukuqinisa isakhiwo sezitshalo nokwenza kube lula ukuvuna. Kodwa leli khemikhali manje lihlolisiswa kabusha embonini yokudla yase-US ngemuva kokutholakala kwalo okungalindelekile nokusabalele ezitokisini ze-oat zase-US. Naphezu kokuthi isivuno sivinjelwe ukudliwa e-United States, i-chlormequat itholakale emikhiqizweni eminingana ye-oat etholakala ukuze ithengwe kulo lonke izwe.
Ukusabalala kwe-chlormequat kwembulwe ngokuyinhloko ngocwaningo kanye nophenyo olwenziwe yi-Environmental Working Group (EWG), okuthe, ocwaningweni lwakamuva olushicilelwe kuyi-Journal of Exposure Science and Environmental Epidemiology, kwatholakala ukuthi ezimweni ezinhlanu i-chlormequat yatholakala kumasampula omchamo wabane babo.
U-Alexis Temkin, isazi sezobuthi e-Environmental Working Group, uveze ukukhathazeka ngemiphumela engaba khona yezempilo ye-chlormequat, ethi: “Ukusetshenziswa kabanzi kwalesi sibulala-zinambuzane esingakafundwa kangako kubantu kwenza kube nzima ukusiphatha. Noma ubani uyazi ukuthi sidliwe.”
Ukutholwa kokuthi amazinga e-chlormequat ekudleni okuyisisekelo aqala kokungatholakali kuya ku-291 μg/kg kudale impikiswano mayelana nemiphumela engaba khona yezempilo kubathengi, ikakhulukazi njengoba i-chlormequat ihlotshaniswa nemiphumela emibi yokuzala kanye nemiphumela emibi yokuzala ezifundweni zezilwane.
Nakuba isikhundla se-US Environmental Protection Agency (EPA) sithi i-chlormequat ibeka ingozi ephansi uma isetshenziswa njengoba kunconywa, ukuba khona kwayo emikhiqizweni ye-oat ethandwayo njenge-Cheerios ne-Quaker Oats kuyakhathaza. Lesi simo sidinga ngokushesha indlela eqinile nebanzi yokuqapha ukutholakala kokudla, kanye nezifundo ezijulile ze-toxicological kanye ne-epidemiological ukuze kuhlolwe ngokuphelele izingozi zempilo ezingaba khona ezihlobene nokuchayeka kwe-chlormequat.
Inkinga enkulu isezindleleni zokulawula kanye nokuqapha ukusetshenziswa kwezindlela zokulawula ukukhula kanye nezibulala-zinambuzane ekukhiqizweni kwezitshalo. Ukutholakala kwe-chlormequat ekuhlinzekweni kwe-oat yasekhaya (naphezu kwesimo sayo esivinjelwe) kukhombisa ukushiyeka kohlaka lokulawula lwanamuhla futhi kukhomba isidingo sokuqiniswa okuqinile kwemithetho ekhona kanye mhlawumbe nokuthuthukiswa kweziqondiso ezintsha zezempilo yomphakathi.
UTemkin ugcizelele ukubaluleka komthetho, ethi, “Uhulumeni wobumbano udlala indima ebalulekile ekuqinisekiseni ukuqapha okufanele, ucwaningo, kanye nokulawulwa kwezibulala-zinambuzane. Kodwa i-Environmental Protection Agency iyaqhubeka nokushiya umsebenzi wayo wokuvikela izingane kumakhemikhali ekudleni kwazo. Umthwalo wemfanelo wengozi engaba khona.” izingozi zempilo ezivela kumakhemikhali anobuthi njenge-chlormequat.”
Lesi simo siphinde sigcizelele ukubaluleka kokuqwashisa abathengi kanye nendima edlalwayo ekukhuthazeni impilo yomphakathi. Abathengi abanolwazi abakhathazekile ngezingozi zempilo ezingaba khona ezihlobene ne-chlormequat baphendukela kakhulu emikhiqizweni ye-oat yemvelo njengesixwayiso sokunciphisa ukuchayeka kulokhu nakwamanye amakhemikhali akhathazayo. Lolu shintsho alubonisi nje kuphela indlela yokubhekana nempilo, kodwa futhi lubonisa isidingo esibanzi sokucaca nokuphepha emikhubeni yokukhiqiza ukudla.
Ukutholakala kwe-chlormequat ekuhlinzekweni kwe-oat yase-US kuyinkinga enezici eziningi ehlanganisa izindawo zokulawula, ezempilo yomphakathi, kanye nokuvikelwa kwabathengi. Ukubhekana nale nkinga ngempumelelo kudinga ukubambisana phakathi kwezikhungo zikahulumeni, umkhakha wezolimo kanye nomphakathi ukuqinisekisa ukutholakala kokudla okuphephile nokungangcolisi.
Ngo-Ephreli 2023, ephendula isicelo sika-2019 esafakwa ngumkhiqizi we-chlormequat uTaminco, i-Environmental Protection Agency kaBiden yaphakamisa ukuthi ivumele ukusetshenziswa kwe-chlormequat kubhali lase-US, i-oats, i-triticale kanye nokolweni okokuqala, kodwa i-EWG yaphikisana nohlelo. Imithetho ehlongozwayo ayikakaphothulwa.
Njengoba ucwaningo luqhubeka nokwembula imiphumela engaba khona ye-chlormequat namanye amakhemikhali afanayo, ukuthuthukiswa kwamasu aphelele okuvikela impilo yabathengi ngaphandle kokubeka engcupheni ubuqotho kanye nokusimama kwezinhlelo zokukhiqiza ukudla kumele kube yinto eza kuqala.
I-Food Institute ibilokhu “ingumthombo ohamba phambili” wabaphathi bemboni yokudla iminyaka engaphezu kwengu-90, ihlinzeka ngolwazi olusebenzisekayo ngezibuyekezo ze-imeyili zansuku zonke, imibiko yamasonto onke ye-Food Institute kanye nomtapo wolwazi obanzi we-inthanethi. Izindlela zethu zokuqoqa ulwazi zidlula “ukusesha amagama angukhiye” okulula.
