Abstract
There is considering actuality of deverloped construction of aspirating shelter application, which allows decrease needed capacity of system, and decrease water flow rate, and in some case, coceal from two stage air cleaning system as well as decreasing energy demand of system and increase their capacity.On theinmdudtrial experiments were developing methodology of base of caulated parameters of sheler.

Abstract
There were analyzed of available techniques for purposes of technology development and equipment design for used automotive catalysts (exhaust catalytic converter system) processing. These catalysts are contained precious metals. There was selected pyrometallurgical way of processing, and offered methods of overcoming known shortcomings of heat-resistant materials' direct melt. There was manufactured original complex on the ground of furnace with cold crucible (work space of 20 liters), ensuring continuous process of heat-resistant material's cumulative smelting. There were carrying out tests of complex, showed enabling extracting as much as 98 per cents of precious metals into alloy suitable for delivery on refinery. There were intended tracks of further improvements of process and equipment for solution of tasks' broad spectrum for processing of heat-resistant materials.

Abstract
There is offered chemiluminometric method based on application of enzymatic test system for the integrated short-term evaluation of environment pollution. This system is responding on presence of different pollutants, irrespective of its individual chemical nature and complexity of composite mixtures. There was used complex of multienzyme formulation as test system from hors radish's root, possessing by oxidase-peroxidase activity in association with sulfhydryl reagent and substrate-fluorogene. There was introduced a notion of "standard unit of pollution" for unification of Neva-river and other Sankt-Petersburg water basin's pollution intensity.

Abstract
It is investigated efficiency of multifunctional coloristic compositions usage for finishing hair side of fur against impact of deicing agents (calcium chloride). Treatment of hair side by means of developed biologic compositions confers it not only persistent coloristic effect, but protects it from negative influence of deicing agents. It is very important for wear furs in the winter time.

Abstract
There were investigated the methods of paper packaging recovery and development of integrated technology for convert these packaging materials into useful products. These methods allow completely recovered cardboard component of packaging Tetra-Pak. In this case, there is possibility emerges to obtain from waste bioactive substances (enzymes and plant growth stimulants) under action of glucose's microorganisms. Accordingly, these bioactive substances make good the global deficit of proteins. This technology could successfully use in agriculture as well as advanced way of paper packaging recovery.

Abstract
There were developed technology and equipment with programmed controlling for mechanical treatment of slab, fitted with automatic control system for working feed of logging. The equipment had certification tests as well as production approvement. Offered equipment and technology allow not only conserve material and energy resources during mechanical treatment of waste wood, but promoted conservation of forest resources owing in-depth treatment of wood.

Abstract
It is established that under the action of gas transportation liquids is occurred substantive phase transfer amplification. It is depicted that methane biooxidation velocity under introduction of gas transportation liquids at water phase is increased at 1.17-1.3 time, and this result is correlated with oxygen volumetric coefficient of mass transfer. Studying results could serve as physical-chemical base for development of chemical and biochemical processes amplification methods, that are limiting by mass transfer of marginally soluble gases from gas phase into water phase.

Abstract
This was analyzed transformation of petroleum contaminants' processes at ingress of oil and petroleum products in environment for the purpose of selection optimization of remediation technologies. While investigations were used current data on petroleum product and its derivatives' behavior as well as updated approaches to simulation of its transformatiob and migration. Obtained results could place accordingly with its practicable significance into higher priority for applied ecology in many different fields of industry. In connection with ratification of Russia Stockholm Convention on persistent organic pollutants represented data should promote investigations in selected direction. Results of investigations enable to evaluate and minimize risks, stipulated by migration of transforming components of oil and petroleum products, including the most dangerous components – polycyclic aromatic hydrocarbons.

Abstract
As an example of Orenburg City, it is carrying out structural and quantitative analysis of pollutions, discharging into water objects as wastewater, generated by enterprises of industrial-transport complex and housing services and utilities, storm waters and thawing waters. There was investi- gated chemical composition of Ural River in background and control site and in zone of aeration station. It is substantiated necessity of maximal snow utilization, offered concept of mobile snow-clearing complex. It is offered quantitative evaluation of waste treatment facilities' facilities, substantiated necessity of local treatment system's creation.

Abstract
This was analyzed outdoor air pollution in case of biogas' burning at cogeneration units. Calculated pollution level for 4 harmful substances at units with power from 60 until 1000 kVt at different heights of stack.

Abstract
There are demonstrated that the application of magnesia-silicate materials leads to change of mineralogical composition of wall accretion, that generated by high basic ferriferous slag of electrical furnaces and converters. As a result, we could observe increasing of refractory properties and lining resistance.

Abstract
There are carried out measurements of traffic intensity for studied streets, computed level of air pollution. At the first time for given land implemented in-situ measurements of acoustic pollution for some areas of town, and carried out questionnaire of citizens, lived nearby motorways. There are proposed noise-protective measures, decreasing level of acoustic load until regulatory level.
