A new embedded-transportable monitoring system (SHARE-BOX), specifically designed to perform atmospheric observations in remote regions, has been deployed at Askole from 20th August to 10th November 2012. The system was equipped with an integrated weather station (Vaisala WXT 520), condensation particle counter (CPC - TSI 3010) able to provide total number concentration for particles with diameters 15 nm < Dp < 3 micron, ozone analyser (Ozone Monitor 220 2B Technologies) and a probe for carbon dioxide measurements (Vaisala CARBOCA GMP 343).

Wet depositions have been collected at the EVK2CNR Pyramid site, in Sagarmatha National Park. Daily and weekly samples have been collected during the monsoon season in 2007 and 2008. Ionic content, total nitrogen and low molecular weight organic acids have been analysed by Ion Chromatography and colorimetric methods.

Two sampling campaign were carried on in 2007 and 2008 in order to collect running water samples from high elevation zone (4500-5500 m asl) in the Sagarmatha National Park. 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.

Persistent Organic Pollutants (POPs) and Polycyclic Aromatic Hydrocarbons (PAHs) are important classes of compounds of serious environmental concern. These compounds were measured in waters, sediments and soils from several high altitude sites in the Sagarmatha National Park (Nepal) and included in the Himalayan ridge. In water samples, low-level substituted PCBs and PBDEs, along with more volatile PAHs, were the most common contaminants. In sediment and soil samples, the PCB profile was mainly composed of medium-level chlorinated congeners and significantly correlated with altitude. The PAH profile for water and soil samples showed the main contribution of pyrogenic PAHs due to emissions of solid combustion, whereas the profile for sediments indicated the main contribution of pyrogenic PAHs from gasoline emissions. The PAH levels measured in Himalayan samples must be considered as low to medium contaminated, whereas the regarded Himalayan stations can be considered undisturbed remote areas concerning PCB, PBDE and OC compounds.
