Abstract

The paper presents a process that allows determining the volumetric configuration of contamination of soil components with a linear source of organochlorine pesticides to their maximum allowable concentrations with a limited amount of field research data. The work was carried out on the basis of the data of sampling and analysis of samples of soil components polluted with organochlorine pesticides and a mathematical analysis of pollution concentrations as a function of the distance and depth of sampling of the samples studied from the center of linear pollution. The paper points out the shortcomings of the standard method for determining soil contamination, the main of which is a greater number of sampling points on the surface of soil components and in depth, which leads to a significant increase in the time of sampling and analysis of samples and an increase in the total cost of monitoring. The basis of the process proposed in the work was the assertion that the concentration of organochlorine pesticides contaminating soil components is a function of distance and depth from the center of pollution, that is, the concentration of pollutant is approximated by non-linear (exponential) regression dependence. The paper presents the sequence of operations of the proposed process: recognition of the regression model of changes in the concentration of pollutants; selection and analysis of a small number of samples of soil components; finding unknown parameters of the adopted regression equation; mathematical calculation of the concentration of organochlorine pesticides in soil components; check the quality of the regression using the coefficient of determination; calculation of the volume configuration of pollution. The paper presents the configurations of contamination of soil components with organochlorine pesticides, up to their maximum permissible concentrations, on the territory of a large warehouse of their former storage, which were obtained with a limited amount of data.
