The results of field, chemical analytical and numerical studies of aerosol deposition of inorganic components in snowpack in the environ of Novosibirsk thermal power plant (TPP) No 5 in winter season of 2018/19 are presented. The snowpack sampling was made in the mainstream winter wind rose directions at the distances of 1.0 – 20.0 km. After melting, the samples were analyzed by the methods of atomic absorption, atomic emission, capillary electrophoresis, pH- , conductivity and gravimetry measurements. It was shown that there is the concentration decreasing with the distance from the source for the following parameters as sediment, the content of main macro- and some microelements in a whole. In order to identify the impurity belonging to a joint source, there was done the microelement statistical correlations. The numerical analysis of snow cover contamination monitoring data on the basis of reconstruction model of weakly settling impurities is presented and discussed.
The results of field and chemical analytical investigation of aerosol contamination of snowpack in the vicinity of Novosibirsk electrode making plant fulfilled in 2016 are presented. The correlation analysis of intercomponent composition of aerosol impurity deposition was done. Using monitoring data, the numerical reconstruction of sedimentation fields of macto- and microelements was made. It was shown that the major sources of pollution are the tall pipes of the factory.
The paper presents data on chemical composition of snow cover samples collected in the vicinity of Iskitim cement plant in March of 2017. The high pH values, the presence in large content of Ca2+, Mg2+, Na+, K+, Cl–, NO3–, SO42– and the existence of pair correlations between them assume to be a unique source of pollution, namely the cement plant dust. Chemical thermodynamic modeling the samples equilibrium composition and the space dynamics reconstruction models approve the conclusion.
