COD ni ikimenyetso cyerekana gupima ibirimo ibinyabuzima mumazi. Iyo COD iri hejuru, niko umwanda uhumanya umubiri wamazi nibintu kama. Ibintu bifite ubumara byinjira mu mubiri w’amazi ntabwo byangiza ibinyabuzima mu mubiri w’amazi nk’amafi gusa, ahubwo birashobora no gukungahazwa mu biribwa hanyuma bikinjira mu mubiri w’umuntu, bigatera uburozi budakira. Kurugero, uburozi budashira bwa DDT burashobora kugira ingaruka kumyanya mitsi, kwangiza imikorere yumwijima, gutera indwara zifata umubiri, ndetse bishobora no kugira ingaruka kumyororokere na genetique, bikabyara frake kandi bigatera kanseri.
COD igira ingaruka zikomeye ku bwiza bw’amazi n’ibidukikije. Iyo imyanda ihumanya ifite COD irenze urugero yinjiye mu nzuzi no mu biyaga, niba bidashobora kuvurwa igihe, ibintu byinshi kama bishobora gutwarwa nubutaka buri munsi y’amazi hanyuma bikarundanya mu myaka yashize. Bizatera kwangiza ibinyabuzima byose mumazi, kandi ingaruka zuburozi zizamara imyaka myinshi. Izi ngaruka z'uburozi zifite ingaruka ebyiri:
Ku ruhande rumwe, bizatera impfu nyinshi z’ibinyabuzima byo mu mazi, byangiza uburinganire bw’ibidukikije mu mazi y’amazi, ndetse bisenya byimazeyo urusobe rw’ibinyabuzima byose.
Ku rundi ruhande, uburozi bwirundanya buhoro buhoro mu mibiri y’ibinyabuzima byo mu mazi nk’amafi na shrimp. Abantu nibamara kurya ibyo binyabuzima byo mu mazi bifite uburozi, uburozi buzinjira mu mubiri w'umuntu kandi burundarundane mu myaka yashize, butera kanseri, ubumuga, ihinduka rya gene, n'ibindi. Ingaruka zikomeye zitateganijwe.
Iyo COD iri hejuru, bizatera kwangirika kwamazi yumubiri wamazi asanzwe. Impamvu nuko kwiyeza umubiri wamazi bigomba gutesha agaciro ibyo bintu kama. Iyangirika rya COD rigomba kurya ogisijeni, kandi ubushobozi bwa reoxygene mu mubiri w’amazi ntibushobora kuzuza ibisabwa. Bizahita bigabanuka kuri 0 hanyuma bihinduke leta ya anaerobic. Muri leta ya anaerobic, izakomeza kubora (kuvura anaerobic ivura mikorobe), kandi umubiri wamazi uzahinduka umukara numunuko (mikorobe ya anaerobic isa numukara cyane kandi itanga gaze ya hydrogen sulfide.).
Gukoresha ibyuma byifashishwa bya COD bishobora gukumira neza COD ikabije mu bwiza bw’amazi.
Isesengura rya COD rishobora gukoreshwa cyane muguhitamo amazi yo hejuru, amazi yubutaka, imyanda yo murugo hamwe n’amazi mabi y’inganda. Ntibikwiye gusa mu murima no ku kibanza cyihuta cy’ibizamini by’amazi byihuse, ariko kandi no gusesengura ubuziranenge bw’amazi ya laboratoire.
