Study of energy parameters of abiotic environment in near-field low-frequency electromagnetic field source zone

Grafkina M.V., Nyunin B.N., Sviridova E.Y.


One of the tasks of system ecology is the study of changes in the abiotic environment as a result of economic activity. Currently, environmental monitoring of low-frequency electromagnetic fields in the abiotic environment of built-over lands is based on the study of the amplitude spectrum of electric-field and magnetic-field intensities. On the basis of the similarity of wave processes the authors theoretically showed the possibility of intensymmetric approach to monitoring and definition of complex intensity of low-frequency electromagnetic field. The authors presented the theoretical and practical justification of the study of the active component of the integrated intensity of the near-field zone of low-frequency source of electromagnetic influence. Determination of the active component of the intensity will help to find the direction of the radiation source and develop the most effective methods of protection. Besides, the conducting of intensymmetric measurements of low-frequency electromagnetic fields will allow proceeding to the evaluation of the total negative impact on human and natural environment.

Influence of traffic emission on distribution of heavy metals and benzo(α)pyrene in water of recreational areas

Sorokin A.V., Sotnikova E.V.


A quantitative analysis of the heavy metals and benzo(a)pyrene in soil, water and sediments of several lakes was performed in this work. Quantitative analysis was performed by ICP-MS and HPLC technique. The coefficients of variation, which evidence is uneven, were calculated for the heavy metals and B[a]P in soil, water and sediments. Elements which have high concentrations were found. Components which exceeded background concentrations values were identified. The influence of road traffic flows on the background concentrations for heavy metals in soils and sediments of ponds of recreational areas was determined.

Gureev A.O., Pikulin Y.G.


Steady growth in world energy prices requires finding the optimal conditions for the processes of chemical technology. Results of testing of previously prepared a mathematical model of the process of purification of industrial gases from carbon dioxide. Shows the dependence of the absorption capacity and the amount of absorbed CO2 by the fluid flow. Proved that no need for the use of the liquid flow rate is similar flooding regime of absorber, since at some point the increase of liquid flow ceases to have a significant impact on the overall absorption capacity of the solution. Also shown is the possibility of reducing the flow of solution in industrial environments, which allows to obtain economic benefits from reduced energy consumption on the circulation of the solution and the gas purification process in general. The value of the temperature for maximum rate of chemisorption of carbon dioxide.
