  • Analysis of experience of monitoring fine-particulate air pollution of roadside territories of the European Union countries and Russia

    The article reviews the three methods of assessment of vehicle exhaust gases in the countries of the European Union. In the first method fuel as an indicator of the transportation activity is used in combination with the average emission coefficient. The second method accounts for the fuel consumption of different types of vehicles and their emission standards. The third method allows for calculating exhaust gas emissions in combination with technical data and data on transport activity. The article presents equations to calculate the exhaust gas omission for each method and reviews examples of the particulate matter characteristics of the emissions of passenger and freight transport. The article also proposes the use of a log-normal law for dependence of transition of number of particles to integral functions on mass distribution of particles by diameter.

  • Decorative processing of natural stones

    Results of researches on influence of heat treatment on physicomechanical properties of the clay slates and sandstone extracted in the Rostov region are stated. It is established that the decorative effect for clay slates can be gained by heat treatment at temperatures of 300-500C then rock on all volume changes color with gray to the red-brown. Thus durability of samples at a bend increases by 20-70%. For change of color of a front surface of natural stones structures of coverings on the basis of phosphatic sheaves and the developed low-temperature enamel were considered. For giving to a layer of necessary flowers various ceramic pigments were used. Frost resistance of stones with coverings on the basis of phosphatic sheaves and enamel more than 50 cycles that testifies to the high durability of coupling of a decorative layer with a stone surface. It is defined that by use of simple technological decisions and inexpensive raw materials, the range of flowers of natural stones can be expanded significantly.

  • Assessment of the environmental impact of burning fossil fuels at enterprises of fuel-energy complex

    In article authors considered organic types of fuel as the most widespread sources of obtaining thermal and electric energy at the enterprises of fuel and energy complex. The prevailing types of organic fuel – natural gas, coal, fuel oil are revealed, and also the composition of flue gases depending on a type of the burned organic fuel is analysed. So, when burning natural gas the main polluting substances are nitrogen oxides and carbon oxides. When burning liquid fuel oxides of sulfur and ashes are added to them. Coal burning, besides above-mentioned substances, leads to receipt to the air basin firm particles, particles (flying ashes) consisting from the zolovykh, not burned down solid fuel and soot. Negative impact of the enterprises of fuel and energy complex on environment components is investigated. In the conclusion authors drew a conclusion that, in comparison with other types of organic fuel, burning of natural gas does the minimum harm to environment.
