Azote nikintu cyingenzi gishobora kubaho muburyo butandukanye mumazi nubutaka muri kamere. Uyu munsi tuzavuga kubyerekeranye na azote yuzuye, azote ya amoniya, azote ya nitrate, azote ya azote na azote ya Kjeldahl. Azote yuzuye (TN) ni ikimenyetso gikunze gukoreshwa mugupima umubare wibintu byose bya azote mumazi. Harimo azote ya ammonia, azote ya nitrate, azote ya nitrite nibindi bintu bya azote nka nitrate na nitrate. Azote ya Amoniya (NH3-N) bivuga guhuriza hamwe kwa ammonia (NH3) hamwe na okiside ya amoniya (NH4 +). Ni azote ya alkaline nkeya kandi irashobora gukomoka kubinyabuzima na chimique mumazi. Azote ya nitrate (NO3-N) bivuga ubunini bwa nitrate (NO3 -). Ni azote acide cyane nuburyo nyamukuru bwa azote. Irashobora gukomoka kubikorwa byibinyabuzima byamazi biva muri azote ya amoniya na azote kama mumazi. Nitrite ya azote (NO2-N) bivuga ubunini bwa nitrite (NO2 -). Ni azote acide nkeya kandi ibanziriza azote ya nitrate, ishobora kuboneka binyuze mubinyabuzima na chimique mumazi. Azote ya Kjeldahl (Kjeldahl-N) bivuga igiteranyo cya okiside ya amoniya (NH4 +) na azote kama (Norg). Ni azote ya ammonia ishobora kuboneka binyuze mubinyabuzima na chimique mumazi. Azote mu mazi ni ikintu cyingenzi gishobora kugira ingaruka ku bwiza bw’amazi, ku bidukikije, no gukura n’iterambere ry’ibinyabuzima byo mu mazi. Niyo mpamvu, ni ngombwa cyane kugenzura no kugenzura azote yose, azote ya amoniya, azote ya azote, azote ya nitrite, na azote ya Kjeldahl mu mazi. Ibiri muri azote yose ni ikimenyetso cyingenzi cyo gupima ingano ya azote mu mazi. Mubisanzwe, azote yuzuye mumazi igomba kuba murwego runaka. Kurenza urugero cyangwa hasi cyane ibirimo bizagira ingaruka kumazi meza. Byongeye kandi, azote ya amoniya, azote ya nitrate, azote ya nitrite, na azote ya Kjeldahl na byo ni ibimenyetso by'ingenzi mu kumenya ibintu bya azote mu mazi. Ibirimo nabyo bigomba kuba murwego runaka. Kurenza urugero cyangwa hasi cyane ibirimo bizagira ingaruka kumazi meza. Nkintungamubiri, azote yinjizwa mubiyaga, kandi ingaruka zitaziguye ni eutrophication:
1) Iyo ibiyaga bimeze muburyo busanzwe, usanga ahanini oligotropique cyangwa mesotropique. Nyuma yo kwakira intungamubiri zidasanzwe, intungamubiri z'umubiri w'amazi ziriyongera, zishobora guteza imbere imizi n'ibiti by'ibimera byo mu mazi mu rugero runaka, kandi intungamubiri ntizigaragara.
2) Hamwe nogukomeza kwinjiza intungamubiri nka azote, igipimo cyo kurya intungamubiri n’ibimera byo mu mazi kiri munsi yikigereranyo cyo kwiyongera kwa azote. Ubwiyongere bw'intungamubiri butera algae kugwira ku bwinshi, buhoro buhoro bigabanya ubworoherane bw'umubiri w'amazi, kandi iterambere ry'ibimera byo mu mazi rirabuzwa kugeza igihe rizimira. Muri iki gihe, ikiyaga gihinduka kiva mu kiyaga cyo mu byatsi kigahinduka ikiyaga cyo mu bwoko bwa algae, kandi ikiyaga cyerekana ibiranga eutrophasi.
Kugeza ubu, ibihugu byinshi bifite amategeko akomeye ku bikubiye muri azote nka azote yose, azote ya amoniya, azote ya azote, azote ya azote na azote ya Kjeldahl mu mazi. Niba amabwiriza yarenze, bizagira ingaruka zikomeye ku bwiza bw’amazi n’ibidukikije by’umubiri w’amazi. Niyo mpamvu, buri wese agomba kwitondera kugenzura no kugenzura ibintu bya azote mu mazi kugira ngo amazi y’amazi y’amazi yujuje ubuziranenge bw’igihugu.
Muri make,azote yose, azote ya amoniya, azote ya azote, azote ya azote na azote ya Kjeldahlni ibimenyetso byingenzi byerekana ibintu bya azote mu mibiri y’amazi. Ibirimo ni ikimenyetso cyingenzi cyerekana ubwiza bw’amazi, kandi kugenzura no kugenzura ni ngombwa cyane. Gusa binyuze mu kugenzura no kugenzura ibintu bya azote mu mibiri y’amazi dushobora kwemeza ko ubwiza bw’amazi bujuje ubuziranenge no kurengera ubuzima bw’umubiri w’amazi.
