<prompt> Fingqa isihloko: Ibutho Lase-U.S. seliqale inqubo yokubhubhisa izimpahla zokugcina zesizwe zezikhali zamakhemikhali eziqukethwe emagobolondweni e-artillery acishe abe ngu-800 000. Lezikhali ezethusayo zigcinwe ePueblo Chemical Depot eningizimu yeColorado. Iqoqo lokuqala le-agent yesinaphi labhujiswa ngemva kokuba ososayensi basebenzise iziqhumane ukuze bavule isitsha esivaliwe futhi basigcwalisa ngamakhemikhali wesibili ukuze kungasebenzi oketshezi. Skrolela phansi ukuze ubone ividiyo. Ochwepheshe bazothatha iminyaka emine ukuqeda cishe iziqhumane ezingu - 800 000 eziqukethe i - mustard agent. I-agent yamakhemikhali, ngokuvamile eyaziwa ngokuthi igesi yesinaphi, empeleni inguketshezi olunephunga elifana nesinongo. Kulinganiselwa ukuthi kunamathani angu - 2 600 aleli gciwane lamakhemikhali eliqukethwe emagobolondweni angu - 780 000 kule ndawo. UBruce Huenefeld, ophethe inqubo yokucekela phansi wathi: Wonke umuntu ujabule ngempela, kodwa siyaqaphela, siqinisekisa ukuthi zonke izinqubo zilandelwa ngokunembile. I-agent yesinaphi ingakhubaza noma ibulale ngokulimaza isikhumba, amehlo nezindlela zokuphefumula. Ibhujiswa ngaphansi kwesivumelwano samazwe ngamazwe sika-1997 esivimbela zonke izinhlobo zezikhali zamakhemikhali. Kuzothatha iminyaka emine ukubhubhisa isitokwe sePueblo. Amanye amathani angu-523 esinaphi namagciwane abulala izinzwa agcinwe eBlue Grass Army Depot eKentucky. I-Blue Grass akulindelekile ukuba iqale ukubhubhisa izikhali zayo kuze kube ngu-2016 noma 2017, iqede ngo-2023. Izikhulu zithi inqubo yokucekela phansi iphephile. Ingxenye enkulu yemithombo kaPueblo izohlukaniswa futhi isetshenziswe esikhungweni esizenzakalelayo esibiza amaRandi ayizigidi eziyizinkulungwane ezingu-4,5 esakhiwe endaweni yokugcina impahla. Indawo yokugcina amakhemikhali ePueblo eningizimu yeColorado inendlela yokucekela phansi amagobolondo amakhemikhali alimele. Izwe laseMelika lathi alikaze lisebenzise i-agent yesinaphi kunoma iyiphi impi futhi lavuma ukubhubhisa inqolobane yalo. Amagobolondo acishe abe ngu - 1 400 alimele namabhodlela ensimbi ayishumi nambili e - mustard agent abhekwa njengangafanelekile kuleso sitshalo. Ziyovulwa ngeziqhumane bese zenziwa zingasebenzi ekamelweni elivaliwe, elingaphakathi kwesakhiwo esivaliwe eduze kwesitshalo esikhulu esizenzakalelayo. Amabhodlela ensimbi aqukethe isinaphi esakhishwa...  <response>: I - United States yavuma ukubhubhisa i - mustard yayo ngo - 1997. Lo mkhiqizo wamakhemikhali uvame ukubizwa ngokuthi igesi yesinaphi naphezu kokuba uketshezi. Cishe iziqhumane zezikhali ezingu - 800 000 zizobhujiswa eminyakeni emine ezayo. I - United States yagcina cishe amathani angu - 3 000 alo mkhiqizo.
