    (2004-01-01) Lekova A.; Boiadjiev D.; Kostova S.; Gràncharova A.
    The objectives of this study were to assess the production of nitrate fertilizers taking into account all the stages in its life cycle from ``cradle-to-grave`` via Life Cycle Impact Assessment methodology. Archived data of two artificial fertilizer plants ``Neohim`` and ``Agropolihim`` has been utilized. Definition of the boundaries of the analysis and the stages of the nitrogen fertilizer life cycle, as identification of burdens, chemical and other environmental impacts, have been performed during the production of two types of nitrate fertilizers: stabilized ammonium nitrate and NEOFERT®. Data analysis is conducted by using LCA software - ``TRACI`` of USEPA. Stressors that may have potential effects on the following impact categories: global changing of nitrogen cycle, acidification, eutrophication, global warming, human health criteria, land and water use, have been characterized.
