An indicator that describes the total amount of all forms of nitrogen (ammonium, nitrite, nitrate, organic nitrogen) in water, usually expressed in mg/L
Shows the total concentration of nitrogen compounds, which affects water quality and the condition of ecosystems
A high total nitrogen value indicates organic or chemical pollution, can promote eutrophication, oxygen deficiency and ecosystem degradation
this indicator allows to assess the intensity of the nitrogen cycle and pollution sources
In occupational health and safety assessments (e.g. drinking water quality)
In the control of industrial facilities (wastewater analysis, monitoring of technological processes)
In environmental studies (assessment of the condition of water bodies, monitoring of nitrogen compounds, identification of pollution sources)
