Walxaha birta oksaydhisku waxay soo saaraan midabyo aan sun ahayn, aan dhiig-baxin, cimiladu adkaysi u leh, oo fudud.Okssaydhyada birta ee dabiiciga ah waxaa ka mid ah isku darka hal ama ka badan oo ah ferric oxides ama ferric oxides, iyo wasakh, sida manganese, dhoobo, ama organics.Okssaydhyada birta ee synthetic waxa loo soo saari karaa siyaabo kala duwan, oo ay ku jiraan kuleyl-kulka cusbada birta, sida ferrous sulfate, si loo soo saaro casaan;roobab si ay u soo saaraan huruud, casaan, bunni, iyo madow (tusaale, habka Penniman-Zoph);iyo dhimista iskudhisyada organic by birta (tusaale, nitrobenzene lagu dhimay aniline marka ay joogaan kiimikooyin gaar ah) si ay u soo saaraan huruud iyo madow.Reds waxaa lagu soo saari karaa iyadoo la xisaabinayo jaalaha ama madow.

Waxay ku xooggan yihiin midab madow waxayna aad uga mugdi badan yihiin midabada kale sidaas darteed inta badan waxaa loo isticmaali karaa saami ka hooseeya midabada dabiiciga ah.
