SOIL AIR QUALITY IN THE URBAN ECOSYSTEMS: ENVIRONMENTAL MONITORING OF THE CAMPUS OF THE RUDN-UNIVERSITY
Abstract
Environmental monitoring systems in the cities existing in modern cities allow to control the state of natural (technogenic-natural) systems according to their programs. But it is not possible to receive an information for some special locations despite their significance ? this is a case of the RUDN-University campus. For these purposes an initiative group organized a special monitoring project for the campus. One part of these monitoring program is a control of the soil air quality. This is a one of the most representative parts of the urban ecosystem reflecting all the pollution processes on the territory. For sampling and chemical analyses has been used the standard methods. Total has been gathered the samples from 33 points on the campus area. The samples has been analyzed using the gaz analyser GANK-4 (certified). The results of the measurements obtained were compared: with the maximum permissible concentrations, with background concentrations, with the results of measurements carried out in March 2017. According to the obtained data, the soil absorption coefficient of the pollutants was calculated from air, this coefficient was plotted in the program Surfer 9.0. Assessment of the state of soils according to the coefficient of absorption allows us to conclude that on the territory of the RUDN-University campus a satisfactory state of soils is observed in the forest park area. In the rest of the territory, the soil is practically not able to process or poorly process pollutants emitted by road transport. Hence it can be concluded that motor transport intensively affects the condition of the soil. It is already necessary to develop and begin remediation measures to maintain the greening of the campus. Estimating seasonal changes in pollutant concentrations in the soil on the territory of the RUDN-University campus, it can be said that the state of soils in the zones of maximum impact of vehicles during the summer period has improved, and in the soils of the forest park zone, conversely, the changes from the spring have been negative, pollutant concentrations in the soil have increased.
