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.

The basic approaches to the definition of the concept “ecological safety” are analyzed and their normative-legal interpretation is revealed. The components of ecological policy in a democratic society are considered. The peculiarities of the formation and implementation of ecological management in Ukraine are shown. The structure of ecological management is considered. The basic problems of ecological safety of Ukraine are found out.

The influence of rail transport on the environment creates many problems as it includes violation of the stability of natural landscapes transport infrastructure through the development of erosion and landslides; air pollution by exhaust gases; permanent increase in oil pollution of earth, lead, blowing products and shedding of bulk cargo (coal, ore, cement). Along with the benefits offered by the railway transport, there arise accute lssues of environmental safety during its use, which is caused by its negative and even destructive impacts on the environment.

We develop the elements of a new generalized approach to natural air ventilation of the industrial city. It is based on the Arakawa-Shubert and Glushkov models which allow to give a quantitative reliable modelling an unsteady turbulence in the urban area and atmospheric ventilation dynamics. To calculate the air circulation for the cloud layer arrays, penetrating into the territory of the urban area, we apply the methods of a plane complex field theory. The method allows to calculate the convection parameters and shifting cumulus cloud ensemble from surrounung regions.

The article summarizes the preconditions for the environmental paradigm formation. It has been set up that implementation of the environmental paradigm has been mostly held in sustainable development doctrine that being an economic theory has stimulated the progress of logistics in the direction of "green" logistics. The evolution of the "green" logistics concept has been researched in retrospect. Determinants that will have an impact on its future development have been identified. The development of logistics industry in Ukraine has been analyzed.

National and international approaches to the definition of environmental audit are 
analyzed. Established, that some domestic scholars in their studies are based on the definition 
provided by the Law of Ukraine “On Environmental Audit”. It is proved that an 
environmental audit is closely linked to sustainable agricultural environmental management 
supporting and plays an important point in its information basis. Own approach to the 
interpretation of environmental audit in the context of the rational agricultural use of drained
