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 .
Keywords: river, pollution, ecosystem, nitrogen regim, classification, quality
