The results of the analysis of existing approaches to the determination of the efficiency of trapping pollutants at their sources of isolation, as well as the prediction of residual contamination of the air of working areas. The classification of methods for determining the effectiveness of local suction ventilation systems. Given the technological distinction between the concepts (factor "technology capture") and sanitary (factor "technological breakthrough"), the efficiency of local suction. The tasks of improving the mathematical description of both types of efficiencies.

The article deals withreduce environmental risksmeasures in case of dangerous geological processes. A variant of engineering-geological zoning of the urban area, depending on the state and properties of the geological environment.
Keywords: ecology, geology, risk
It is shown that to describe the phenomena and processes in a transition interfacial layer having a certain thickness, it is useful to distinguish the boundary layer of the surface and boundary diffusion layer, which lies entirely in the less condensed phase related. In accordance with this energy and power characteristics of the transition layer should be attributed to the boundary surface of the interphase transition layer. The basic equation of electro capillary boundary of the surface layer, establishing the dependence of the surface tension of this layer on the chemical composition of the second phase, and bordering the jump of electric potential between them.

The implementation of any construction project is successful only when it is rational planning. At the stage of pre-construction preparation one of the main problems of planning are: the presence of order in the organization of pre-construction preparation, the presence of a modern design and the regulatory framework, the definition of the resource with the time factor, the definition of adequate duration and timing of the project. Selecting the most reliable method of determining the stage of pre-analysis, resource support of the construction process to a large extent affect the implementation of the project. In conditions of uncertainty are the most efficient flexible systems. The technique of construction and update of one of these systems is described in the article.
