Dry and wet deposition of nitrogen emitted in Buenos Aires City to waters of de la Plata River
Dry and wet deposition of atmospheric nitrogen species (NO2 and HNO3) coming from nitrogen oxides emissions in Buenos Aires city to surface waters of de la Plata River were estimated. Atmospheric dispersion models DAUMOD-RD (v.2) and CALPUFF were applied to area and point sources, respectively. Thes...
