I-Chlormequat yaziwa kakhuluisilawuli sokukhula kwezitshaloesetshenziswa ukuqinisa ukwakheka kwezitshalo nokwenza kube lula ukuvuna. Kodwa ikhemikhali manje isingaphansi kokucutshungulwa okusha embonini yokudla yase-US kulandela ukutholakala kwayo okungalindelekile nokusabalele ezitokisini ze-oat yase-US. Ngaphandle kokuthi isitshalo sivinjelwe ukusetshenziswa e-United States, i-chlormequat itholwe emikhiqizweni eminingi ye-oat etholakalayo ukuthengwa ezweni lonke.
Ukusabalala kwe-chlormequat kudalulwe ikakhulukazi ngocwaningo nophenyo olwenziwa yi-Environmental Working Group (EWG), okuthe, ocwaningweni lwakamuva olushicilelwe ku-Journal of Exposure Science and Environmental Epidemiology, lwathola ukuthi ezimweni ezinhlanu i-chlormequat itholwe kumasampula womchamo we ezine zazo. abahlanganyeli abane. .
U-Alexis Temkin, isazi sobuthi se-Environmental Working Group, wazwakalisa ukukhathazeka ngemiphumela engase ibe khona empilweni ye-chlormequat, ethi: “Ukusetshenziswa kabanzi kwalesi sibulala-zinambuzane esingakafundiwe kubantu kwenza kube nzima ukusiphatha. noma ubani uyazi ukuthi udliwe. “
Ukutholakala kokuthi amazinga e-chlormequat ekudleni okuyisisekelo asukela kokungabonakali kuye ku-291 μg/kg kuqubule impikiswano mayelana nemiphumela yezempilo engaba khona kubathengi, ikakhulukazi njengoba i-chlormequat ihlotshaniswa nemiphumela emibi yokuzala kanye nemiphumela emibi yokuzala ezifundweni zezilwane. ngezinkinga zokukhula kombungu.
Nakuba isikhundla se-US Environmental Protection Agency's (EPA) siwukuthi i-chlormequat idala ingozi encane uma isetshenziswa njengoba kunconyiwe, ukuba khona kwayo emikhiqizweni ye-oat edumile efana ne-Cheerios ne-Quaker Oats kuyakhathaza. Lesi simo sidinga ngokuphuthumayo indlela eqinile nephelele yokuqapha ukuhlinzekwa kokudla, kanye nezifundo ezijulile ze-toxicological kanye ne-epidemiological ukuhlola kahle izingozi zezempilo ezingaba khona ezihlobene nokuchayeka kwe-chlormequat.
Inkinga enkulu ilele ezindleleni zokulawula nokugadwa kokusetshenziswa kwezilawuli zokukhula nezibulala-zinambuzane ekukhiqizeni izitshalo. Ukutholakala kwe-chlormequat ezimpahleni ze-oat yasekhaya (naphezu kwesimo sayo sokuvinjelwa) kukhombisa ukushiyeka kohlaka lokulawula lwanamuhla futhi kukhomba isidingo sokuqiniswa okuqinile kwemithetho ekhona futhi mhlawumbe nokuthuthukiswa kwemihlahlandlela emisha yezempilo yomphakathi.
UTemkin ugcizelele ukubaluleka kokulawula, ethi, “Uhulumeni wobumbano udlala indima ebalulekile ekuqinisekiseni ukuqapha okufanele, ucwaningo kanye nokulawulwa kwezibulala-zinambuzane. Nokho i-Environmental Protection Agency isaqhubeka nokulahla igunya layo lokuvikela izingane kumakhemikhali ekudleni kwazo. Isibopho ngengozi engaba khona. " izingozi zempilo ezivela kumakhemikhali anobuthi njenge-chlormequat.”
Lesi simo siphinde sigqamise ukubaluleka kokuqwashisa abathengi kanye neqhaza elilibambayo ekumeleleni impilo yomphakathi. Abathengi abanolwazi abakhathazekile ngezingozi zezempilo ezingaba khona ezihlobene ne-chlormequat baya ngokuya bephendukela emikhiqizweni ye-oat ephilayo njengesexwayiso sokunciphisa ukuchayeka kulokhu namanye amakhemikhali akhathazayo. Lolu shintsho alubonisi nje kuphela indlela yokushesha kwezempilo, kodwa futhi lubonisa isidingo esibanzi sokubeka izinto obala nokuphepha emikhubeni yokukhiqiza ukudla.
Ukutholwa kwe-chlormequat ekuhlinzekweni kwe-oat yase-US kuyinkinga enezici eziningi ehlanganisa izindawo zokulawula, ezempilo yomphakathi, kanye nokuvikelwa kwabathengi. Ukubhekana nale nkinga ngempumelelo kudinga ukusebenzisana phakathi kwezinhlaka zikahulumeni, umkhakha wezolimo kanye nomphakathi ukuze kuqinisekiswe ukutholakala kokudla okuphephile nokungangcoliswa.
Ngo-Ephreli 2023, ephendula isicelo sika-2019 esafakwa ngumkhiqizi we-chlormequat uTaminco, i-Biden's Environmental Protection Agency yahlongoza ukuthi kuvunyelwe ukusetshenziswa kwe-chlormequat ebhali lase-US, i-oats, i-triticale nokolweni okokuqala ngqa, kodwa i-EWG yaphikisana nalolu hlelo. Imithetho ehlongozwayo ayikaphothulwa.
Njengoba ucwaningo luqhubeka nokuveza imithelela engaba khona ye-chlormequat namanye amakhemikhali afanayo, ukuthuthukiswa kwamasu aphelele okuvikela impilo yabathengi ngaphandle kokubeka engcupheni ubuqotho nokusimama kwezinhlelo zokukhiqiza ukudla kufanele kube yinto ehamba phambili.
I-Food Institute ibe undunankulu “umthombo wokuma okukodwa” wabaphathi bemboni yezokudla iminyaka engaphezu kwengama-90, ihlinzeka ngolwazi olungasetshenzwa ngezibuyekezo ze-imeyili zansuku zonke, imibiko yamasonto onke ye-Food Institute kanye nomtapo wolwazi obanzi we-inthanethi. Izindlela zethu zokuqoqa ulwazi zidlula “ukusesha kwamagama angukhiye” okulula.
