Considered relevant for the construction industry the problem of air pollution by dust. A significant level of airborne dust is typical for plants of concrete products and structures. A physical model of the process of mixing of air pollution department, which includes the main stage of the contamination: education, allocation and distribution of pollutants. Ustanovnleno that the main objects of the physical model are contaminant technological raw materials, manufacturing equipment, the workplace air and the ground layer of the atmosphere.
Keywords: Contaminant technological raw materials, manufacturing equipment, workplace air, the physical model of air pollution
Submitted manufacturing operations performed at the landfill site TOP, their main types of negative impacts on the environment. The conditions of formation and emission of biogas generated in the interior of the landfill body and having a pronounced toxic effects. The dependence of the specific biogas yield for the period of his active stable generation.

The main characteristics of the different types of landfills for disposal of solid waste consumption: buried landfills poluzaglublenny landfills and surface polygon. For each landfills for disposal of solid waste consumption the features of operation
Keywords: Solid waste consumption, buried landfills, operation, poluzaglublenny landfills, surface polygons.
Methodical principles for selection of sites for the construction of solid waste landfills consumption suggested by other authors, based on which proposed a new method of selection of the site for the construction of a solid waste landfill consumption, examines its main stages and highlights the main advantages
Keywords: Solid waste consumption, operation, methods of site selection for the disposal of solid waste consumption.
Article is devoted to justification of approaches to research of influence of transport factors on ekologo-economic safety of the country on an example of railway transport. A basis of research is the system approach. The environmental management system on railway transport is offered for considering as set of the objects of railway transport interconnected and mutually influencing at each other and environment elements. Approaches to development of strategy of development of system of environmental management on railway transport and the directions of protection and improvement of a state of environment for service conditions of objects of a regional subsystem of railway transport are proved.

Article is devoted to justification of approaches to development of algorithm of an assessment of influence of railway transport on a state of environment for ensuring ekologo-economic safety of the country. Offers on use what econometrical modeling for development of imitating model of system of environmental management for the purpose of damage prevention to environment from impact on it anthropogenous factors of the enterprises-prirodopolzovateley, including emergency situations are proved. Stages of realization of a technique of an ekologo-economic justification of nature protection administrative decisions in environmental management system on railway transport are considered.
