BOD (tlhoko ea oksijene ea biochemical):

Tlhoko ea Oksijene ea Biochemical, kapa BOD, ke bongata ba oksijene e qhibilihisitsoeng e hlokoang ke lintho tse phelang tse phelang metsing ho bolisa lintho tse phelang tse teng sampole e fanoeng ea metsi mochesong o itseng bakeng sa nako e itseng. Polelo ena e boetse e bua ka mekhoa ea lik'hemik'hale e sebelisoang ho fumana bongata. Ena ha se teko e nepahetseng ea lipalo, leha e sebelisoa haholo e le sesupo sa boleng ba metsi a tlhaho. BOD e ka sebelisoa e le sesupo ho lekanya katleho ea limela tsa kalafo ea metsi a litšila. E thathamisitsoe e le tšilafalo e tloaelehileng linaheng tse ngata.

COD (Tlhoko ea Oksijene ea Lik'hemik'hale):

K'hemistri ea tikoloho, teko ea tlhoko ea oksijene ea lik'hemik'hale (COD) hangata e sebelisoa ho lekanya ka tsela e sa tobang bongata ba metsoako ea lintho tse phelang metsing. Litšebeliso tse ngata tsa COD li fumana bongata ba litšila tse silafatsang tse fumanoang metsing a holim'a metsi (joalo ka matša le linōka) kapa metsing a litšila, e leng se etsang hore COD e be sesupo se molemo sa boleng ba metsi.
