The article actualizes the environmental problem of ammonia emission in industrial and residential buildings into the indoor air environment.
In the process of studies it has been established that the main sources of ammonia emission into the indoor air are concrete structures (concrete walls, ceilings, columns, etc.) and finishing materials.
In concrete, ammonia is formed as a result of hydrolysis of urea (NH2)2CO contained in concrete, and urea (urea) and other similar substances are used as hardening gas pedals and anti-freeze additives, including ammonized fly ash.
It is possible to prevent ammonia emission into the indoor air not only by checking construction materials for cases of exceeding the maximum permissible concentration of urea in them, but also by experimental determination of amide nitrogen concentration in concrete mixtures at the stage of their delivery to construction sites.
The aim of the article is to present an experimental technique to determine amide nitrogen concentration in construction materials developed to control amide nitrogen concentration at the stage of concrete mixture delivery to construction sites to exclude ammonia formation after putting construction sites of different functional purposes into operation.
Experimental method for determining the concentration of amide nitrogen in building materials is the result of solving the following research tasks:
– examination of building materials by methods of physical and chemical analysis for the quantitative determination of amide nitrogen;
– comparison of the obtained results with the data of research laboratories with the conclusions about the quality of performed analyses.
Approbation of the proposed experimental method for determining the concentration of amide nitrogen in building materials was carried out in the laboratory of the test center «OOO«Settle City» in Kudrovo.

To perform many tasks in the system of EMERCOM of Russia, databases have been developed with the ability to select an aircraft model according to tactical and technical characteristics of helicopter and airplane types. Databases are presented in the form of digital and text invariants, in a certain range of numerical values, which provides search, processing and identification using a computer, on the SQLite3 database management system and for Windows 7 and higher operating systems. The databases in question can be used by employees and specialists of search and rescue teams and other services of EMERCOM of Russia to streamline and differentiate the approach in choosing the necessary unmanned aircraft system of the aircraft type to perform the tasks, taking into account the terrain and conditions of their use. The principle of operation is in the process of filling the database with information about the available models designed to equip the units of EMERCOM of Russia, so that in the future it would be possible to conduct a sample.

In order to develop reliable calculation methods for monitoring and predicting the impact of emissions from boats on the environment in cities, it is necessary to carry out experimental studies of the exhaust emissions of boat engines. The purpose of the present study was to carry out mooring (stationary) tests to measure the concentrations of carbon monoxide, carbon dioxide, nitrogen oxides and hydrocarbons in the exhaust emissions of the YaMZ-238 GM2 engine used as a power unit on single-deck tourist motor ships, crew boats, etc., by means of the gas analyzer «Infracar 5M3T.02L». It was found that the content of pollutants in the exhaust emissions of the engine did not exceed standard values, and the obtained values of average specific emissions for the YaMZ-238 GM2 engine correlated well with the corresponding values of foreign methods.

The purpose of the research is to substantiate the possibility of using carbon nanostructures in robotic fire extinguishing installations at facilities with the circulation of petroleum products. The paper presents the results of measuring the surface tension and viscosity of water with a wetting agent modified with carbon nanostructures (astralens), as well as determining the mass burnout rate of a flammable liquid under the conditions of supplying a fire extinguishing agent. The results of measurements of the extinguishing time of a class B model focus and the time of thermal destruction of a foaming agent film on the surface of a combustible liquid are presented. Based on the research, it was concluded that fire extinguishing compositions modified with astralenes should be used in robotic fire extinguishing installations at facilities with the circulation of petroleum products in order to provide thermal protection and reduce the time to extinguish a fire.

Modern polymer materials used in construction, transport and household products characterized, as a rule, by high flammability and combustibility, which has a significant impact on ensuring the required level of fire protection. A variant of the formalization of the choice of a flame retardant coating is proposed and an algorithm for its justification is proposed. The proposed algorithm for choosing a fire-retardant coating assumes a preliminary quantitative assessment of fire danger; analysis of possible scenarios of fire development; the choice of the type of fire protection system taking into account the operating environment, the size of potential damage from fire, technical, economic and human factors, and the rationale for choosing a fire-resistant coating that provides the specified (required) level of fire protection.

The trend observed in recent years towards an increase in crimes involving the use of combustion accelerators focuses the attention of specialists on issues related to the identification of two or more samples of thermally modified petroleum products. The solution of this problem will give results not only in establishing the circumstances of criminal crimes, but also in identifying the perpetrators of spills of liquid petroleum hydrocarbons, as well as spill fires. The article presents the results of a study of thermally altered samples of various brands of light petroleum products by atomic emission spectral analysis in terms of diagnosing metal impurities, the quantitative contents of which are proposed as identification criteria. The analysis of the obtained results substantiates the need for further research aimed at solving the problem of establishing the identity of two or more samples of petroleum products.

It is shown that the group of flame-retardant effectiveness does not actually reflect the nature and degree of realization of the mechanism of flame retardant action of flame retardants, their ability to influence the features of thermal transformations of wood. It has been established that the type of flame retardant, its chemical component composition and the mechanism of flame retardant action to varying degrees affect the main stages of thermal oxidative decomposition of wood.

The physical phenomenon of smog formation from burning peat bogs and its persistent air pollution on the highway is investigated. It is shown that particulate smog particles of small sizes PM10 and PM2.5 are capable, as on condensation nuclei, of creating optically dense aerosol fogs and, thereby, reducing the visibility range on the roadway to 50 meters or less, significantly increasing the risk of traffic accidents. It is proved that, together with carbon monoxide CO, smog saturates the air with pollutants to dangerous concentrations that can significantly weaken the reflex reactions of drivers to changing traffic conditions. In combination, this leads to an emergency situation, accompanied by a transport collapse, requiring the involvement of forces and means of emergency response.
