            ABSTRACT. The variation of nitrogen characteristics indicators in the surface water from Barcau hydrographical basin during the 1993-2009 period. The purpose of this paper is to determine the variation of nitrogen forms characteristic indicators, from surface water of the Barcau River, and their interacting with the environment. The evolution of these parameters was analyzed for eight first level monitoring sections (Boghis, Suplacu de Barcău downstr., Marghita downstr., Parhida, Kismarja, Pocsaj, Berettyˇ˙jfalu and Szeghalom), located on the main course; it characterizes large sections of the river and the influence of a different points of wastewater discharge, like anthropogenic influence factors. String data used is homogeneous, obtained by the systematic observations, between 1993-2009.

Keywords:ammonia, nitrites, nitrates, monitoring sections, water contamination
