The Apodi/Mossoró basin is one of the most important water resources in the state of Rio Grande do Norte. Recent studies have shown that nitrogen compounds stand out among the river’s main contaminants. There is thus a need to relate their presence to other physicochemical properties that influence their formation. This paper aims to correlate the concentrations of NO3-, NO2- and NH3 with the values of pH, T, Eh and DO in the waters of this basin. The results indicate the predominance of a strongly oxidizing environment, highlighting NO3- as the main form of nitrogen present, even in places where significant reductions in Eh and OD were observed. This paper gives a contribution for the development of control and treatment of sources of pollution and better management of water resources. |
