- Аннотация: The ultimate goal of ecological research for EANET is to evaluate an effect of atmospheric pollution on the properties of regional environment ecosystems and their changes under air pollutant impact. This study presents the first estimation of the annual input-output budget components of sulfur and nitrogen compounds at the natural catchment area of a small river in the Far East of Russia for 2005-2015. The assessment is based on the considered principal individual components of pollutant transfer: atmospheric wet and dry deposition fluxes and river runoff discharge. The study was conducted for Komarovka river catchment where the Russian EANET ecological site Primorskaya was established in 2002. Most of the data for the calculations were collected as part of regular performing at the EANET program measurements. The procedures of atmospheric deposition flux estimation were done in line with EANET Technical documents. Our results of budget components estimation demonstrate that the values of sulphur compounds (SOx) output from watershed were higher than their input for the same period for the most of years. In opposite, for nitrogen compounds (NHx and NOx) the atmospheric input exceeded the output at river catchment. Presented results can be applied for the further elaboration of pollutant migration in ecosystem and out as well as to be used for comparisons with similar studies at the other EANET ecological monitoring sites.
