ABSTRACT
The Baia Mare city - the residence of Maramures county, is known as one of the most polluted cities from Romania, following a long history of mining activities and ores processing. The improper treatment of wastewater from flotation and treatment with cyanide ores and their discharge into the river Sasar led, slowly, but surely destroying the ecosystem. In addition to mining activities have contributed of course, and the metallurgical activities in the area. One of constant pollutions is and disposal of sewage waste water (treated poorly or not at all) in the mass water of the Sasar river. The nitrogen regime may provide clues as to the possibility of developing various forms of life, being an indicator of the nutrient regime of aquatic life. This study aims at assessing the quality of the nitrogen regime of Sasar river, in the section upstream and downstream of Baia Mare, in the period 2000-2010, with reference to the Order 161/2006 - regarding the classification of surface water quality to determine the ecological status of water bodies .
