Ioksijini yemolekyuli enyibilikisiweyo emanzini ibizwa ngokuba yioksijini enyibilikisiweyo kwaye idla ngokubizwa ngokuba yi-D0. Ubungakanani beoksijini enyibilikisiweyo emanzini angaphezulu yi-5-10mg/L. Xa kukho imimoya enamandla kunye namaza, ioksijini enyibilikisiweyo emanzini inokufikelela kwi-14mg/L. Ubungakanani beoksijini enyibilikisiweyo = ixabiso elilinganisiweyo leoksijini enyibilikisiweyo/ubungakanani beoksijini enyibilikisiweyo phantsi kweemeko ezilinganisiweyo * 100%, oko kukuthi, i-90% nangaphezulu, ixabiso elilinganisiweyo lingaphezulu kwe-7.5 mg/L, kwaye ubuncinci yi-2 mg/L.
Ioksijini ephantsiamanziiya kudlula kwizityalo ize isuse ioksijini kwiingcambu. Ngokufanayo, iya kunciphisa ioksijini emhlabeni. Izityalo ezisempilweni kunye nezityalo zomhlaba ezisempilweni zifuna ioksijini kwezi ndawo zimbini.
Ukungabikho kweoksijini enyibilikisiweyo emanzini kunokubangela nezinye iingxaki. Umzekelo, ii-nematodes zithanda umhlaba ongena-oxygen. Ukunkcenkceshela izityalo ngamanzi angenayo ioksijini eninzi kuya kuzisondeza kumphezulu kwaye konakalise iingcambu zezityalo ngokulula.
Izifundo zibonise ukuba ukunciphisa uxinzelelo lweoksijini enyibilikisiweyo kwindawo yeengcambu zezityalo kuya kunciphisa amandla ezityalo okufunxa initrogen namanzi. Ukunqongophala kweoksijini kunokonakalisa iingcambu. Kwinkqubo yokuziqhelanisa noxinzelelo oluphantsi lweoksijini enyibilikisiweyo, imetabolism yezityalo itshintshile. I-Hypoxia ngaphakathi kwesityalo ibizwa ngokuba yi-hypoxia yangaphakathi. Esinye seziphumo kukuwohloka kwe-sucrose, kwaye izityalo zijika ziye kwiindlela zokonga amandla ukuze zibuyisele ukungabikho kweoksijini.
I-photosynthesis ye-phytoplankton yeyona mthombo uphambili weoksijini emachibini, ngokubanzi ibandakanya i-56%-80% yomthombo weoksijini; okuseleyo kuvela ekuvutheni komoya kunye namaza, ukuze ioksijini esemoyeni inyibilike ngqo emanzini.amanziIluncedo 12-14mg/L
IHeilongjiang: A 600-square-imithaichibi lokuthambisa i-tanning linokunyusa ubushushu bamanzi ngama-degrees ama-3 ukuya kuma-4 kwaye lonyuse imveliso yengqolowa nge-6%.
