REGRESSIVE DEPENDENCE OF THE BIOLOGICAL PROCESSES ACTIVITY IN SOLID HOUSEHOLD WASTE ON THE DEGREE OF ITS COMPACTION IN THE COURSE OF TIME (Ukr)

2022

In recent years the total area of the landfills and refuse dumps of solid municipal waste, including overloaded facilities and those, where the norms of ecological legislation are violated and are the objects of the intensive ecological loading has greatly increased in Ukraine. This may cause the pollution of the environment by chemical substances and leads to chemical pollution of the soil. Determination of the regression dependence of benzopyrene concentration in the soils of the landfills of solid municipal waste on the depth of measuring is an important scientific engineering problem.Aim of the research is to determine the regression dependence of benzopyrene concentration in the soils of the landfills of solid municipal waste on the depth of measuring. In the process of study the method of regression analysis of the results of single-factor experiments and other pair dependences with the selection of the rational type of function from sixteen most widely spread variants by the criterion of the maximum value of the correlation factor was used.Regression was carried out on the base of linearized transformations, which enable to reduce the nonlinear dependence to linear one. Determination of the coefficients of the regression equations was carried out by means of the least squares method, using the developed computer program "RegAnaliz", protected by the Certificate of the state registration of the rights to the copyright object.Adequate regression power dependence of benzopyrene concentration in the soils of the landfills of solid municipal waste on the depth of measuring was obtained, the dependence was used for the determination of the dangerous depth of chemical pollution of the soils. Graphic interpretation of the dependence of benzopyrene concentration in the soils of the landfill of solid municipal waste on the depth of measuring is constructed, this interpretation enables to illustrate this dependence and show the coincidence of the theoretical results with the actual results on the level of 0.96975. It was established that the dangerous depth of chemical pollution of the soils of the landfill of solid municipal waste with benzopyrene is 152 mm.

In recent years the total area of the solid municipal waste landfills and dumpsites, including the overloaded ones, which violate the norms of ecological safety and are the objects of intensive ecological loading, that may cause the pollution of the environment with chemical substances, contaminating soil, in particular with the lead has greatly increased. Determination of the regression dependence of lead concentration in the soil on the distance to solid municipal waste landfills is an important scientific-technical problem.Objective of the research is to determine the regressive dependence of lead concentration in the soil on the distance to solid municipal waste landfills. During the research the method of regressive analysis of the results of single-factor experiments and other pair dependences with the selection of the rational type of function from sixteen most widely spread variants by the criterion of maximum value of the correlation factor has been used. Regression was performed on the base of the linearizing transformations, which enable to reduce the nonlinear dependence in to linear one. Determination of the coefficients of the regression equations was carried out by means of the least squares method, applying the developed computer program "RegAnaliz", protected by the Certificate of the State registration of the rights to the copyright object.Adequate regressive power dependence of the lead concentration in the soil on the distance to solid municipal waste landfills was obtained, the dependence can be used for the determination of the level of chemical pollution of the soil with lead. Graphic interpretation of the lead concentration dependence in the soil on the distance to solid municipal waste landfill was constructed, it enables to illustrate this dependence and show the coincidence of the theoretical results with actual results on the level of 0.93493. It is established that the distance from the landfill of solid municipal waste, where the lead pollution of the soil does not exceed the background level (boundary of mild contamination area), is 526 m.

REGRESSION ANALYSIS OF PETROLEUM PRODUCTS CONCENTRATION IN THE SOILS OF MUNICIPAL SOLID WASTE LANDFILLS (Eng)

2022

In recent years the total area of the municipal solid waste landfills and waste dumps, including overloaded, which violate the norms of ecological safety and are the objects of the intensive ecological loading, that pollute the environment with chemical substances, causing chemical pollution of the soils, in particular, with the petroleum products, has greatly increased. Determination of the regression dependence of the petroleum products concentration in the soils on the distance to the landfills of municipal solid waste is the relevant scientific-technical problem.Objective of the study is determination of the regression dependence of the petroleum products concentration in the soils on the distance to the municipal solid waste landfills. Regression was performed on the base of the linearized transformations, which enable to reduce the nonlinear dependence to linear one. Determination of the regression equations coefficients was performed by the method of the least squares with the help of the elaborated computer program "RegAnaliz", protected by the Certificate of the State registration of the rights to the copyright object.Adequate regression power dependence of the petroleum product concentration in the soils on the distance to the landfills of municipal solid waste was obtained, the dependence was used for the determination of the safe distance for the solid municipal landfills location from the agricultural lands by the index of the level of chemical pollution of the soil with petroleum products. Graphic interpretation of the dependence of the petroleum products concentration in the soil on the distance to the landfill of municipal solid waste is constructed, this interpretation enables to illustrate this dependence and show the coincidence of the theoretical results with the actual results on the level of 0.9999996. It was established that the safe distance for the location of the landfills of municipal solid waste from the agricultural lands by the index of the level of chemical pollution of the soil with petroleum products is 66 m.
