The paper discusses the use of different biocenosis to clean soil from oil pollution. Indicated that the use of artificial biocenosis expensive and not always effective. It is shown that the use of natural ecological communities, for example, in the form of activated sludge wastewater treatment plants were selected on the oil refineries are much cheaper and as effective as the action of biological products, which are based on artificial biocenosis.

One of the most promising methods of radioactive waste decontamination, used salt fusion – sorption purification method with the use of lithium and potassium inoculated NaA zeolite sorbent (LiKNaA) is considered. Sorption properties of inoculated LiKNaA sorbent in the course of salt treatment produced as a result of processing by non-aqueous methods of four fuel elements with dense spent fuel elements from BOR-60 reactor from fission products in the static regime under the conditions of the protective chamber have been studied. The high boundary of salt mass fraction trapped by the sorbent as a result of occlusion is determined. An assessment of decontamination index of salt by cesium and cesium radionuclides distribution coefficient in the sorbent is carried out. On the basis of the performed researches, the recommended salt - LiKNaA sorbent mass ratio is proposed at which the salt decontamination index will be not less than 9 and the mass fraction of sodium, lithium, and potassium in the salt varies nonessentially, which allow us to regenerate salt many times for recovery to the process.

The raw-material base of non-ferrous metal production can be extended now as a result of recycled material and technogenic product processing. For the zinc industry, a special interest can concern polymetallic dusts of the copper production containing a complex of valuable components including zinc, lead, tin, and copper. An actual problem is selective extraction of the metals in the course of industrial processing of dusts. The work describes the copper processing practice now in force at OAO "Chelyabinsk Zinc Works"; the basic technical problems concerned with inhomogeneity of properties of various zinc-containing raw materials are presented. The phase and element compositions of the subject of inquiry – dusts of allowing powder materials – are given. Based on the results of the thermodynamic simulation of the pyrometallurgical copper dust processing practice, the principal reactions promoting the distillation of volatile zinc, lead, and tin compounds at the conditions of high temperatures have been analyzed. The results of kinetic parameter determination for sublimation reactions of the said metals are given. From the results of some laboratory researches, the basic optimum conditions are developed for the maximum transit of zinc, lead, and tin compounds into gas phase at the Waelz process of dusts of the copper production.

Physical and chemical processes of decomposition of some "criterion" contaminants of surface and wastewaters (phenol and some synthetic surfactants) in plasma systems have been studied. The decomposition degrees of examined compounds were from 75 to 99 % depending on the processing conditions. Intermediate materials are shown to be carboxylic acids, aldehydes, sulfate-ions, and nitrate-ions. Carbon dioxide was the finite product of decomposition of aldehydes and carboxylic acids. Based on experimentally measured concentrations of phenol, sulfonol, and sodium laurilsulfate decomposition products, the potential toxicity of initial solutions and the solutions after plasma effect for the purpose of determination of effectiveness of its decrease has been calculated. The results with the data obtained by biotesting method are compared.

The overall performance of all industries must be estimated from the point of view of the balance between the main product mass and the volume technogenic waste products formed. The researches have shown that phosphate binder, produced by tempering of iron-containing slag from thermal power station and 70 % ortho-phosphoric acid, begins to fasten in 45 – 50 min and solidifies in 2 – 2.5 h. Subsequently, when the contents of iron orthophosphates in cement stone increases, its strength grows roughly directly proportional to solidification time in the air conditions, and after seven days it can be stabilized at level of 45.0 – 50.0 МПа. Upon introducing aluminum-containing dead-catalyst into the composition of iron-containing slag from thermal power station with ortho-phosphoric acid, the refractoriness of mixed iron-phosphate binding agent increases to practically directly proportional to the value of aluminum oxide contents.

The effect addition of various types of waste products to clayey raw materials on processing characteristics of raw masses designed for manufacture of aglite grail has been investigated. To correct the composition of clayey raw materials by the contents of iron oxides, grinding sludge is examined. Oil-containing slimes are considered as a correcting additive by the contents of organic matter. The possibility of correcting the clayey raw material composition by the contents of iron oxides, free silicon dioxide, and calcium oxide is defined by an additive of galvanic sludges. As a correcting organomineral additive, settings of sludge banks at the plants of biological treatment of water of the housing and utilities and waste coal characterized by increased contents of iron and carbon oxides have been investigated. Application of the examined waste types as correcting additives to clayey raw materials allows us to obtain raw masses designed for manufacture of aglite grail with improved performances, besides to eliminate their warehousing in refuse dumps and holding lagoons.

Bioplateau creation researches at Kirovogorsky sediment pond of AO "OLKON" (Olenegorsk, Murmansk Region) have been carried out for the purpose of decrease in water of mineral nitrogen compounds ingressive into the pond with waste quarry waters as a result of explosive works with the use of nitrogen compounds. The assortment of indigenous plants has been selected; the method of their fixing and cultivation on the water surface is developed; and observation of their vegetation is carried out. In the conditions of laboratory and full-scale experiments, the dynamics of decreasing the mineral forms of nitrogen compounds is found. The necessary area of the pond bioplateau coating for decrease of the mineral nitrogen compounds is calculated. Application of the floating bioplateaus promoted decrease in water of the sediment pond of the contents of ammonium and nitrite nitrogen to values of maximum concentration limit and lower. The trend of nitric nitrogen concentration decrease is marked as well. The developed process can be applied in any climatic zone with characteristic to the locality assortment of plant-improvers.

The investigation is performed in a mid-taiga subzone of Karelia. The influence of harvesters on the properties of forest soils is investigated in conditions of a model field experiment. When performing the study, we used a complex approach and all-rounded evaluation of the properties of podzolic soils. It is shown that the most pronounced changes in soil properties are followed on logging roads. The change of morphological properties, which was expressed in the change of the soil profile structure, is established. The presence of artefacts indicates the anthropogenic past of these solids. The variation in chemical properties of soils was diagnosed by the content of mineral feeding elements of plants and ash content. The changes in microbe community are revealed against the background of the anthropogenic effect. Our data can be used when planning the forestry measures. Microorganisms sensitive to the change of a soil medium can be used as an indicator of the state of soils of anthropogenically transformed ecosystems.

The "waste products" normative concept used in the normative-legal documentation is analyzed. The ambiguity of interpretation is shown to be able to affect the accounting system in handling with waste products.

Advantages of applying street railway in solving the problems of providing the mobility of urban population and environmental safety. It is shown that additional vibration and noise sources, which generate uncomfortable state of human, appear if the tramroad state is unsatisfactory. A mathematical model for evaluating the vibration and noise when the tram moves over tramroad sections, which disagree with the sanitary code, is proposed.
