Ku wa kabiri, tariki ya 14 Gashyantare, abaturage bo mu Ntara ya Pima mu majyepfo ya Arizona basabwe kwimuka cyangwa guhungira mu ngo nyuma yuko ikamyo yari itwaye aside nitricike ikora impanuka igasesa ibiyirimo ku muhanda ukikije.

Iyi mpanuka yabaye ahagana mu ma saa mbiri n'iminota 43 z'ijoro kandi irimo ikamyo y'ubucuruzi ikurura “ibiro 2000” (~ 900 kilo) ya acide ya nitric, yaguye, ihitana umushoferi ndetse ihungabanya inzira nini y'iburasirazuba-iburengerazuba yambuka igice kinini cy'amajyepfo ya Amerika. Iburengerazuba.

Ababajijwe bwa mbere, barimo ishami ry’umuriro wa Tucson hamwe n’ishami ry’umutekano wa Arizona, bidatinze bahungishije abantu bose mu kirometero kimwe cya kilometero 0.8 cy’impanuka maze bategeka abandi kuguma mu ngo no kuzimya ubukonje ndetse n’ubushyuhe. Nubwo nyuma itegeko rya "ubuhungiro-mu-mwanya" ryakuweho, biteganijwe ko hakomeje kubaho imvururu ku mihanda ikikije aho impanuka yabereye kuko imiti ishobora guteza ibibazo.

Acide Nitric (HNO3) ni amazi atagira ibara kandi yangirika cyane aboneka muri laboratoire nyinshi zisanzwe kandi akoreshwa mu nganda zitandukanye nk'ubuhinzi, ubucukuzi bw'amabuye y'agaciro, no gukora amarangi. Acide ikunze kuboneka mugukora ifumbire aho ikoreshwa mu gukora nitrati ya amonium (NH4NO3) na nitrate ya calcium ammonium (CAN) ifumbire. Hafi y'ifumbire mvaruganda hafi ya azote yose ikoreshwa mubigega by'ibiryo bityo hakaba hakenewe byinshi kuri bo kuko abatuye isi biyongera kandi bagakenera cyane umusaruro w'ibiribwa.

Ibi bintu kandi bikoreshwa nkibibanziriza mu gukora ibisasu kandi byashyizwe ku rutonde kugira ngo bigenzurwe mu bihugu byinshi bitewe n’ubushobozi bwabo bwo gukoresha nabi - nitrati ya amonium mu byukuri yari nyirabayazana y’iturika rya Beirut mu 2020.

Acide Nitric yangiza ibidukikije kandi ni uburozi kubantu. Guhura na aside, nk'uko Ikigo gishinzwe kurwanya no gukumira indwara (CDC) kibitangaza, bishobora gutera uburakari ku maso no ku ruhu kandi bishobora gutera ibibazo bitandukanye bitinda by’ibihaha, nka edema, pneumonitis, na bronchitis. Uburemere bwibi bibazo biterwa nigipimo nigihe cyo kumurika.

Amashusho n'amafoto yafashwe nabenegihugu yerekana igicu kinini cya orange-umuhondo kiguruka mu kirere aho impanuka yabereye Arizona. Iki gicu gikorwa na acide ya nitric iyo ibora ikabyara gaze ya azote.

Isuka ya nitric ije nyuma yiminsi 11 gusa gari ya moshi itwara imizigo ya Norfolk y'Amajyepfo yasohotse muri Ohio. Ibi birori kandi byatumye abaturage bimurwa mu gihe vinyl chloride yatwaraga mu modoka eshanu za gari ya moshi yafashwe n'inkongi y'umuriro maze yohereza ibyuka bya hydrogène hydrogène na fosgene mu kirere.
