New methods of control of ecological state of soils and municipal wastewater
The object of the research is dynamics of heavy metal pollution of soils and sewage. The main factors affecting the degree of air pollution, soil and water resources in highly populated areas are described. Some indicators of the ecological state of urban facilities are shown. The aim of this study is the application of new control methods based on x-ray fluorescence analysis to assess the anthropogenic changes of the soil environment and municipal wastewater. In the main part of the study the results of the research of soil and municipal wastewater by x-ray fluorescence analysis are given as a resalt of the research. It is shown that the degree of contamination of soils correlated with the degree of depletion of the species composition of microalgae. By examining the x-ray fluorescence spectra of the samples of aquatic plants it is established that high efficiency of wastewater treatment is happened by using algae. The author proposes a rapid method of monitoring the ecological state of soils and municipal wastewater on the basis of x-ray fluorescence analysis.
