Obiettivo TO BETTER UNDERSTAND THE ROLE OF AMMONIA IN THE ATMOSPHERIC CYCLE OF NITROGEN COMPOUNDS, IN VIEW OF THEIR CONTRIBUTION TO THE ACIDIFICATION OF SOILS. THE RESEARCH PROJECT IS DIVIDED IN FOUR SUB-PROJECTS: 1. ESTIMATION OF THE EMISSIONS OF NH3 IN THE E.C. MEMBER STATES FROM EXISTING LITERATURE DATA. SPATIAL DISTRIBUTION AND VARIATIONS IN TIME ARE TAKEN IN ACCOUNT. 2. COLLECTION AND EVALUATION OF EXISTING DATA ON CONCENTRATION LEVELS OF NH3 AND NH4+ IN AIR OF NH4+ IN PRECIPITATION. 3. MEASUREMENT OF NH3 CONCENTRATION LEVELS AND NH3 DEPOSITION VELOCITIES ON SELECTED SITES AND DURING SUMMER AND WINTER SEASONS. 4. ESTIMATION OF THE DEPOSITION FLUX OF TOTAL AMMONIA (NH3 + NH4+) FROM THE DATA OBTAINED IN SUB-PROJECTS 2 AND 3.
