The water samples will be analyzed for the main nitrogen species (N-NO3, N-NH4, TN) and for the principal hydro-chemical constituents (Ca, Mg, Na, K, Cl, SO4, HCO3). The concentration and the temporal variation of nitrogen species were related to the N concentration of lakes and to the fluxes of wet deposition from the same area. The overall purpose of this research is the study of the hydrological and biological processes controlling the nitrogen cycling in the Himalayan alpine ecosystem. As this region represents one of the most remote and uncontaminated site in the world, the results of this study could be very useful to understand the phenomenon occurring in the Alps, in relation to the climate changes too Balestrini Raffaella IRSA-CNR Researcher Via del Mulino 19 Brugherio Lombardy 20861 Italy balestrini@irsa.cnr.it thumbnail large_thumbnail nitrate, ammonia, snow, precipitation , hydrology, biological processes Khumbu Valley, Sagarmatha eng boundaries 2007-10-07T17:35:00 2008-10-07T17:36:00 80.0522 88.1946 26.3684 30.4247 You can customize the template to suit your needs.
