Nitrosamine ni imwe muri kanseri eshatu zizwi cyane ku isi, izindi ebyiri ni aflatoxine na benzo [a] pyrene.Nitrosamine ikorwa na nitrite na amine ya kabiri muri poroteyine kandi ikwirakwizwa cyane muri kamere.Ibigize nitrosamine mu mafi yumunyu, shitingi yumye, byeri, bacon na sosiso ni byinshi. Igihe kinini cyo gushyira igihe cyo kuzuza inyama n'imboga nacyo gishobora kubyara nitrite. .Nitrite na nitrate ni imyunyu ngugu idasanzwe mu ndyo ya buri munsi n'amazi yo kunywa. Muri rusange abantu bemeza ko gufata cyane ibyo bintu bishobora gutera metemoglobinemia kandi bikabyara nitrosamine ya kanseri mu mubiri.Nitrate na nitrite ni ionic ihumanya muri GB 2762-2017 yitwa "Ikigo cy’igihugu gishinzwe umutekano w’ibiribwa -Imipaka ihumanya ibiryo".GB 5009.33-2016 yiswe "Ibipimo ngenderwaho by’umutekano w’ibiribwa mu rwego rwo kumenya Nitrite na Nitrate mu biribwa" ni uguhuza kugena ibyo bintu byombi, hamwe na ion chromatografiya nkuburyo bwa mbere bwashyizwe mubipimo.
Ingero zabanjirijwe hakurikijwe GB / T 5009.33, hanyuma nyuma yimvura ya poroteyine no kuvanaho amavuta, ingero zavomwe kandi zisukurwa nuburyo bukwiranye.Ukoresheje CIC-D160 ion chromatografi, SH-AC-5 inkingi ya anion, 10.0 mM NaOH eluent hamwe nuburyo bwo gutwara bipolar pulse, mubihe byasabwe na chromatografique, chromatogramu nuburyo bukurikira.
