In publication overflows and leaks of oil products are considered on petrol filling stations. The materials used to collect overflows and leaks of oil products on petrol filling stations are indicated. Disadvantages of sand and properties of silica clay are considered. The petroleum was used for carrying experiments to collecting of oil products by sand and silica clay. The experiments were carried out and the data on changes in the mass of petroleum remaining on the samples (particles of silica clay, particles of sand) from initial mass of the samples (before contact with petroleum) were received. The assumption was made about the possibility of using silica clay instead of sand to collect overflows and leaks of oil products in urban environment.

Data on the effect on human health of dust from office air conditioners are presented. The microbial and dispersion composition of dust has been studied. Studies have shown that the microbial number in the rooms depends on the floor on which the air conditioner is installed. Also, the presence of large fractions of dust decreases with increasing height at which the air conditioner is installed.

The article is devoted to the calculation and assessment of background pollution of the atmosphere srednebalansovogo integral criterion for the studied regions of Volgograd for the years 2010-2013. Assessing the background air pollution, and creating a map of alternative sites for new industrial construction, is determined srednebalansovy integral criterion of pollution of the atmosphere of the study area. This requires calculation of the average concentration of harmful substances in each group summation of polluting the area. The data obtained were built integral and differential distribution function srednebalansovogo integral criterion of atmospheric pollution for Volgograd regions. According to the analysis the greatest volume of air pollution falls on Central and Traktorozavodskiy districts, which corresponds to the results of the calculations of the specific pollution load on the atmosphere of the city.

The article reviews questions about description disperse composition and concentration of dust using the theory of stationary random functions. This approach allows us not only to obtain the characteristics of disperse composition of dust in the air, but also determine the number of additional parameters, namely, the average residence time fractional concentration above a predetermined level, the average number of outputs fractional concentration per unit time for a fixed level. Examples of correlation functions that can be used to approximate empirical data in the case of stationary процесс are submitted.
