ECOLOGICAL SAFETY OF IVANO-FRANKIVSK URBAN SYSTEM ACCORDING TO ACOUSTICAL AND ELECTROMAGNETIC LOAD FACTORS

Abstract

The article outlines the directions of the ecological safety formation on the territory of IvanoFrankivsk urban system according to acoustic and electromagnetic load factors. In order to provide an acoustically comfortable environment for inhabitants of the urban system the authors solved the following tasks: measurements of the equivalent sound level along the highways and near the residential buildings close to the roads were made; special attention was paid to the public transport stops where the audio-boxes of the "Street Radio " are located. In general, an equivalent sound level Leqv was measured at 165 points within the territory of Ivano-Frankivsk urban system. According to the research results separate zones (streets) with the greatest acoustic discomfort within the city were allocated, profiles of acoustic load distribution along main streets were built, taking into account the equivalent sound level in the green zones of the city which are located nearby. Using the software program Surfer a noise map for the territory of Ivano-Frankivsk was built. To ensure a comfortable living environment within the urban system according to the factor of electromagnetic load the following tasks were solved: isotropic measurements of the electromagnetic field components at 122 points of the test-ground were carried out. At each point in terms of maximum and average values the following parameters were measured: electric field strength (E, V/m); magnetic field strength (H, mA/m); surface energy flux density (W, mkW/cm2). Base cellular network stations were recorded, their contribution to the electromagnetic situation of the city was described. The maps of technogenic electromagnetic pollution were built with the help of the program Surfer for the spatial analysis of changes in the electromagnetic field levels within the urban system. Spline interpolation method was used to build the maps. Moreover, measurements of 5 basic test objects of the urban system were carried out, which are the most vulnerable to the electromagnetic field influence. According to the research results the schematic images of the electromagnetic field distribution inside the objects were built. The most sensitive zones within the test objects were determined. Thus, according to the analysis of the conducted research favorable zones for comfortable and safe residence in Ivano-Frankivsk urban system according to the factors of noise and electromagnetic pollution were determined.
