I-Chlormequat yinto eyaziwayoumlawuli wokukhula kwezityaloisetyenziselwa ukuqinisa ulwakhiwo lwezityalo kunye nokwenza kube lula ukuvunwa. Kodwa le khemikhali ngoku iphantsi kovavanyo olutsha kwishishini lokutya lase-US emva kokufunyanwa kwayo okungalindelekanga nokubanzi kwi-oat stocks yase-US. Nangona isivuno singavumelekanga ukutyiwa e-United States, i-chlormequat ifunyenwe kwiimveliso ezininzi ze-oat ezikhoyo ukuze zithengwe kulo lonke ilizwe.
Ukuxhaphaka kwe-chlormequat kutyhilwe ikakhulu ngophando nophando olwenziwe yi-Environmental Working Group (EWG), ethi, kuphononongo lwakutshanje olupapashwe kwi-Journal of Exposure Science and Environmental Epidemiology, ifumanise ukuba kwiimeko ezintlanu i-chlormequat ifunyenwe kwiisampulu zomchamo wabane babo.
UAlexis Temkin, ingcali yetyhefu kwi-Environmental Working Group, uvakalise inkxalabo malunga nemiphumo enokubakho kwimpilo ye-chlormequat, esithi: “Ukusetyenziswa ngokubanzi kwesi sibulali-zinambuzane esingafundwanga kangako ebantwini kwenza kube nzima ukusilawula. nabani na uyazi nokuba sityiwe.”
Ukufunyanwa kokuba amanqanaba e-chlormequat ekutyeni okuqhelekileyo aqala kwi-291 μg/kg kubangele ingxoxo malunga nemiphumo enokubakho kwimpilo yabathengi, ingakumbi kuba i-chlormequat iye yanxulunyaniswa neziphumo ezibi zokuzala kunye neziphumo ezibi zokuzala kwizifundo zezilwanyana.
Nangona isikhundla se-US Environmental Protection Agency (EPA) sikukuba i-chlormequat ibeka umngcipheko ophantsi xa isetyenziswa njengoko kucetyiswayo, ubukho bayo kwiimveliso ze-oat ezidumileyo ezifana neCheerios kunye neQuaker Oats kuyaxhalabisa. Le meko ifuna ngokungxamisekileyo indlela engqongqo nebanzi yokujonga ukubonelelwa kokutya, kunye nezifundo ezinzulu zetyhefu kunye ne-epidemiological ukuvavanya ngokupheleleyo iingozi zempilo ezinokubakho ezinxulumene nokuvezwa kwe-chlormequat.
Ingxaki ephambili ikwiindlela zokulawula kunye nokubeka esweni ukusetyenziswa kwabalawuli bokukhula kunye nezibulali-zinambuzane kwimveliso yezityalo. Ukufunyanwa kwe-chlormequat kwimveliso ye-oat yasekhaya (nangona imeko yayo ivaliwe) kubonisa ukusilela kwesakhelo solawulo sanamhlanje kwaye kubonisa imfuneko yokunyanzeliswa okungqongqo kwemithetho ekhoyo mhlawumbi nokuphuhliswa kwezikhokelo ezintsha zempilo yoluntu.
UTemkin ugxininise ukubaluleka komthetho, esithi, “Urhulumente wobumbano udlala indima ebalulekileyo ekuqinisekiseni ukuba ukubekwa esweni ngokufanelekileyo, uphando, kunye nokulawulwa kwezibulali-zinambuzane. Sekunjalo i-Environmental Protection Agency iyaqhubeka nokuyeka umyalelo wayo wokukhusela abantwana kwiikhemikhali ekutyeni kwabo. Uxanduva lwengozi enokubakho.” iingozi zempilo ezivela kwiikhemikhali ezinobuthi ezifana ne-chlormequat.”
Le meko ikwagxininisa ukubaluleka kolwazi lwabathengi kunye nendima eyidlalayo ekukhuthazeni impilo yoluntu. Abathengi abanolwazi abaxhalabileyo malunga neengozi zempilo ezinokubakho ezinxulumene ne-chlormequat baya beguqukela ngakumbi kwiimveliso ze-oat eziphilayo njengendlela yokuthintela ukunciphisa ukuvezwa koku kunye nezinye iikhemikhali ezixhalabisayo. Olu tshintsho alubonisi nje kuphela indlela yokujongana nempilo, kodwa lukwabonisa isidingo esibanzi sokungafihlisi kunye nokhuseleko kwimisebenzi yokuvelisa ukutya.
Ukufunyanwa kwe-chlormequat kubonelelo lwe-oat lwase-US yingxaki eneenkalo ezininzi equka iinkalo zolawulo, impilo yoluntu, kunye nokukhuselwa kwabathengi. Ukujongana nale ngxaki ngempumelelo kufuna intsebenziswano phakathi kwee-arhente zikarhulumente, icandelo lezolimo kunye noluntu ukuqinisekisa ukuhanjiswa kokutya okukhuselekileyo nokungenazo iintsholongwane.
Ngo-Epreli 2023, ukuphendula isicelo sika-2019 esafakwa ngumvelisi we-chlormequat uTaminco, i-Arhente yoKhuseleko lokusiNgqongileyo kaBiden yacebisa ukuvumela ukusetyenziswa kwe-chlormequat kwirhasi yase-US, i-oats, i-triticale kunye nengqolowa okokuqala, kodwa i-EWG yachasa esi sicwangciso. Imithetho ecetywayo ayikagqitywa.
Njengoko uphando luqhubeka nokutyhila iimpembelelo ezinokubakho ze-chlormequat kunye nezinye iikhemikhali ezifanayo, uphuhliso lwezicwangciso ezibanzi zokukhusela impilo yabathengi ngaphandle kokubeka emngciphekweni ukuthembeka kunye nokuzinza kweenkqubo zemveliso yokutya kufuneka kube yinto ephambili.
I-Food Institute ibisoloko “ingumthombo ophambili” kubaphathi beshishini lokutya kangangeminyaka engaphezu kwama-90, inika ulwazi olusebenzayo ngohlaziyo lwe-imeyile yemihla ngemihla, iingxelo zeveki ze-Food Institute kunye nethala leencwadi lophando elikwi-intanethi. Iindlela zethu zokuqokelela ulwazi zidlula “ukukhangela amagama angundoqo” nje.
