Atmospheric air quality is one of the determining factors of environmental state and public health.Atmosphere near the big cities is influenced by both local and regional sources of pollution.Researches of the chemical composition of atmospheric precipitation allow to assess the level of pollution of the atmosphere and to identify the sources of this pollution.The aim of this work is to evaluate the current trace metals pollution of atmospheric environment of Barnaul city and to considerate applying the HYSPLIT model to identify possible sources of trace elements.Sampling point was located on the roof of the Institute building,samples of precipitations events collected during cold season 2013-2014.Concentrations of trace metals were determined by ICP-MS(ICAP-Qc,Thermo Scientific),mercury concentration were determined by CVAFS(Mercur DUO Plus,Analitik-Jena).Concentrations of metals in precipitation during the study period vary widely.Correlation between the concentrations of elements and the amount of precipitation is different for heavy metals and anions.The pair correlation coefficients between the concentrations of the studied metals and the amount of rain precipitation ranged from-0.55 to-1.0.While for snow precipitation the reverse correlation was observed only for some metals.Absence of correlation between the amounts of snow and metal content may indirectly indicate that the sources of these metals are not only local urban but also regional emissions due to medium-and long atmospheric transport.In order to determine the possible pollution sources of trace metals in precipitations,the correlation between them in samples was determined.Significant correlation of some metals with each other indicated internal relationships among these elements due to common sources of pollution.Individual considered of trace metals ratios in separate precipitation events combined with HYSPLIT model allow to identify possible sources of these metals and their transport pathways.As an example the maximum concentrations of most heavy metals were determined in precipitation sampled at December 5,2013.On this day,there was a dramatic warming,lowering of atmospheric pressure and rain precipitation due to incursion into the territory of the Altai moist and warm southwestern air masses.The trajectory of air masses passed through the East Kazakhstan region,where the main non-ferrous metallurgy plants are located.Their emissions could be the main sources of high concentrations of metals in atmosphere and further deposition with precipitation on the territory of the Altai,as evidenced a characteristic set of metals in precipitation samples.
