An indicator of the amount of organic and some inorganic reducing substances in water, determined by their oxidation with potassium permanganate (KMnO₄); expressed as the amount of oxygen consumed (mg O₂/L)
Shows the chemical composition of water and the level of organic pollution, which affects its suitability for domestic, industrial and ecosystem stability
A high permanganate oxidation value indicates intensive organic pollution, which can lead to oxygen deficiency in water bodies and damage to ecosystems
In occupational health and safety assessments (drinking water quality)
In water control of industrial facilities (wastewater analysis, technological processes)
In environmental studies (assessment of the condition of water bodies)
