In recent years in Ukraine, the total area of the solid domestic waste dumps and landfills, including the overloaded ones, which violate the norms of ecological safety and are the objects of the intensive ecological loading has grown. This may cause the pollution of the environment with harmful substances: heavy metals, microorganisms (colibacilli bacteria, streptococci, staphylococci, ascarids), high toxic filtrate, landfill gas, etc., giving rise to diseases. Determination of the regression dependences of various diseases incidence among the adult population of the residential areas, adjacent to the disposal sites on the distance to the solid domestic waste dump is an actual scientific engineering problem. The aim of the research is the determination of the regressive dependences of various diseases incidence among the adult population of the residential areas, adjacent to the disposal sites on the distance to the solid waste dump. In the process of the research the method of the regression analysis of single-factor experiments results and other pair dependences with the selection of the best type of function from the sixteen the most spread variants by the criterion of the maximum value of the correlation factor was used. The regression was carried out on the base of the linearized transformations, which enable to reduce the non-linear dependence to linear one. The determination of the coefficients of the regression equations was carried out, applying the method of the least squares by means of the developed computer program "RegAnaliz". Adequate regression power dependences of the diseases of various types incidence among the adult population of the residential areas, adjacent to the disposal sites on the distance to the dump are obtained. These dependences are used for the determination of the safe distance for the location of the solid domestic waste dumps from the residential areas by the indices of the pathology incidence of the respiratory system and diseases of the circulatory system. Graphic dependences of various types of the diseases spreading among the adult population of the residential areas, adjacent to the disposal sites on the distance to the dump, these dependences allow to illustrate these dependences and show the sufficient convergence of the theoretical results with the actual data.
