Abenzi bokudla okuziinkozo: Kutheni i-oats yethu iqulethe i-chlormequat?

I-Chlormequat yinto eyaziwayoumlawuli wokukhula kwezityaloisetyenziselwa ukomeleza ubume bezityalo kunye nokuququzelela ukuvuna. Kodwa imichiza ngoku iphantsi koqwalaselo olutsha kwishishini lokutya lase-US kulandela ukufunyanwa kwayo okungalindelekanga kunye nokuxhaphaka kwe-oat stocks yase-US. Ngaphandle kokuba isityalo sivaliwe ukuba sisetyenziswe e-United States, i-chlormequat ifunyenwe kwiimveliso ezininzi ze-oat ezikhoyo ukuze zithengwe kwilizwe lonke.
Ukuxhaphaka kwe-chlormequat kutyhilwe ikakhulu ngophando kunye nophando olwenziwe yi-Environmental Working Group (EWG), eyathi, kuphononongo lwakutsha nje olupapashwe kwiJournal of Exposure Science and Environmental Epidemiology, yafumanisa ukuba kwiimeko ezintlanu i-chlormequat yabhaqwa kwiisampulu zomchamo. ezine kuzo. abathathi-nxaxheba abane. .
UAlexis Temkin, osisazi ngetyhefu kwi-Environmental Working Group, wavakalisa inkxalabo ngemiphumo enokubakho empilweni yechlormequat, esithi: “Ukusetyenziswa ngokubanzi kwesi sibulali-zinambuzane singafundwanga kangako ebantwini kwenza kube nzima ukusilawula. nabani na uyazi ukuba udliwe. “
Ukufunyaniswa ukuba amanqanaba e-chlormequat ekutyeni okusisiseko aqala ngokungabonakaliyo ukuya kwi-291 μg/kg kuye kwavusa ingxoxo malunga neziphumo zempilo ezinokuthi zibekho kubathengi, ngakumbi kuba i-chlormequat inxulunyaniswe neziphumo ezibi zokuzala kunye neziphumo ezibi zokuzala kwizifundo zezilwanyana. kwiingxaki zophuhliso lomntwana.
Nangona indawo ye-Arhente yoKhuseleko lweNdalo yase-US (EPA) ikukuba i-chlormequat ibeka umngcipheko ophantsi xa isetyenziswa njengoko kunconyiwe, ubukho bayo kwiimveliso ze-oat ezithandwayo ezifana ne-Cheerios kunye ne-Quaker Oats buyaxhalabisa. Le meko ifuna ngokungxamisekileyo indlela engqongqo nebanzi yokubeka iliso kubonelelo lokutya, kunye nezifundo ezinzulu ze-toxicological kunye ne-epidemiological ukuhlola ngokucokisekileyo imingcipheko yempilo enokubakho enxulumene nokuvezwa kwe-chlormequat.
Eyona ngxaki ingundoqo ilele kwiindlela zolawulo kunye nokongamela ukusetyenziswa kwezilawuli zokukhula kunye nezitshabalalisi kwimveliso yezityalo. Ukufunyanwa kwe-chlormequat kwizinto ze-oat zasekhaya (nangona imeko yayo ivaliwe) ibonisa iintsilelo zesikhokelo solawulo lwanamhlanje kwaye ikhomba imfuneko yonyanzeliso olungqongqo lwemithetho ekhoyo kwaye mhlawumbi nokuphuhliswa kwezikhokelo zezempilo zoluntu.
UTemkin ugxininise ukubaluleka kolawulo, esithi, “Urhulumente womanyano udlala indima ebalulekileyo ekuqinisekiseni ukubekwa esweni okufanelekileyo, uphando, kunye nolawulo lwezibulali-zinambuzane. Nangona kunjalo i-Arhente yoKhuseleko lokuSingqongileyo iyaqhubeka nokushiya igunya layo lokukhusela abantwana kwiikhemikhali ekutyeni kwabo. Uxanduva ngengozi enokwenzeka. ” iingozi zempilo kwiikhemikhali eziyityhefu njengechlormequat.
Le meko iphinda ibonise ukubaluleka kokwazisa abathengi kunye nendima eyidlalayo ekukhuthazeni impilo yoluntu. Abathengi abanolwazi abanenkxalabo malunga nemingcipheko yempilo enokubakho enxulumene nechlormequat baya beguqukela kwiimveliso ze-oat ephilayo njengenyathelo lokunciphisa ukuvezwa koku kunye nezinye iikhemikhali ezixhalabisayo. Olu tshintsho alubonisi nje kuphela indlela esebenzayo kwimpilo, kodwa lukwabonisa imfuno ebanzi yokungafihli kunye nokhuseleko kwiindlela zokuvelisa ukutya.
Ukufunyanwa kwe-chlormequat kubonelelo lwe-oat yase-US ngumba onezinto ezininzi ezithatha iindawo zolawulo, impilo yoluntu, kunye nokhuseleko lwabathengi. Ukusombulula le ngxaki ngokufanelekileyo kufuna intsebenziswano phakathi kwee-arhente zikarhulumente, icandelo lezolimo kunye noluntu ukuze kuqinisekiswe ukubonelelwa kokutya okukhuselekileyo nokungangcolisi.
Ngo-Epreli ka-2023, ukuphendula kwisicelo sika-2019 esifakwe ngumvelisi we-chlormequat uTaminco, i-Arhente yoKhuseleko lokuSingqongileyo yase-Biden icebise ukuba ivumele ukusetyenziswa kwe-chlormequat kwibhali yase-US, i-oats, i-triticale kunye nengqolowa okokuqala, kodwa i-EWG yasichasa isicwangciso. Imithetho ecetywayo ayikagqitywa.
Njengoko uphando luqhubeka lubonisa iimpembelelo ezinokuthi zenzeke kwi-chlormequat kunye nezinye iikhemikhali ezifanayo, ukuphuhliswa kwezicwangciso ezibanzi zokukhusela impilo yabathengi ngaphandle kokuphazamisa ingqibelelo kunye nokuzinza kweenkqubo zokuvelisa ukutya kufuneka kube yinto ephambili.
Iziko loKutya libe yinkulumbuso "yendawo yokumisa enye" ​​yabaphathi beshishini lokutya ngaphezulu kweminyaka engama-90, ibonelela ngolwazi olusebenzayo ngohlaziyo lwe-imeyile yemihla ngemihla, iingxelo zeVeki yeZiko loKutya kunye nethala leencwadi elibanzi lophando kwi-Intanethi. Iindlela zethu zokuqokelela ulwazi zidlula ngaphaya "kokukhangela amagama angundoqo."
