This article concentrates on the analysis of mercury concentration in uneven-aged needles of different wood species on the territory of peat bog ecosystems of Tomsk Region. The following original data is given: level of mercury accretion and peculiarities of allocation depending on a strain of conifers, needles age, and landscape and climate conditions. Mercury concentration data obtained on the territory of Tomsk Region does not exceed the data appearing in the cited literature. In general it lies within average concentration’s range for the territory of Siberia and Russia.
The article deals with the experimental data, on which base the mercury level and modes of occurrence are detected in the insoluble fractions of aerosol in snow and in snowmelt water in the impacted areas of Seversk thermal power plant. The geochemical indices were calculated, the value of mercury load on the snow cover in the conventionally near field and far field impacted areas of fuel and energy complex enterprise was defined.
Snow, as short-term consignation Wednesday, has several properties that lead to its widespread use in ecologicalgeochemical and geological research. By studying the chemical composition of the dust fallout you can indirectly assess the condition of atmospheric air.<sup>1-2</sup>. Determining the content of mercury in snow cover, you can define its contribution for the longest period of the year in our region, with the most intensive use of various types of fuel (coal, gas, firewood), that puts a strain on urban ecosystems in terms of ecology.<sup>3-4</sup>. In addition, snow cleans the atmosphere of mercury, but it accumulates in the snow, and during the spring melting of snow hits the ground and rivers, polluting them. Part of the mercury back into the atmosphere. It should also be note the special nature of the circulation of air masses over the city in winter, creating a heat CAP, which contributes to air pollution of the city. <sup>5-6-7</sup>. The high load areas of industrial impact were detected during the eco-geochemical investigations of mercury load index in the impacted areas of enterprises of Tomsk. It was found out, that aerosol particles of industrial emissions in Tomsk contain mercury. The contamination transfer character of mercury sources and occurrence modes of pollutants in snow solid residue were detected during the researches of industrial impact.
