Among the important problems of today, one should single out environmental security in the con- ditions of a full-scale war in Ukraine. Since the war has affected the regions of Ukraine in different ways, it is relevant to study the formation of a regional policy for financing environmental protection costs in the conditions of a full-scale war, which is the purpose of the presented article.

The migration of highly concentrated pesticide solutions in the soil has been experimentally studied. A mathematical model of the diffusion process in the soil environment has been developed. Based on the mathematical model, a system of equations for calculating the duration and intensity of the process depending on environmental parameters was obtained. The dependence of the process velocity on the direction of the diffusion front is determined, and the diffusion coefficients, kinetic coefficients of the diffusion process and the diffusion front velocity were calculated.
