The paper is devoted to the study of the microbiota of the river waters, located in the southern region of the Azerbaijan Republic. As a result of studies performed, we have determined the classification, the prevalence of micromycetes in different substrates and their frequency. In the studies, the water temperature, dissolved oxygen, pH and concentration of nutrients are measured. The studies have been conducted during all the seasons. The results obtained show that the amount of micromycetes is maximal in summer, and in winter their number is minimal.

The influence of the content of copper oxide nanoparticles (NP CuO) and Cu2+ ions in the medium on their accumulation in the hemolymph of the mussel Crenomytilus grayanus is studied. The effect of copper oxide nanoparticles and metal ion (Cu2+) on cholinesterase activity in hemolymph of mussels is estimated. Multidirectional effects of CuO and Cu2 + nanoparticles on the copper content and cholinesterase activity in hemolymph are demonstrated. At the initial stage of the experiment, cholinesterase activity is shown to decrease in the case of the ionic form of copper, and in the case of copper nanoparticles, the activity increases. At the final stage of the experiment, an opposite situation for the considered forms of copper is observed.

The paper considers biomechanical characteristics of motor by the example of volleyball technical techniques. In the course of the experiment, as a model we use two volleyball techniques, namely 1) feeding the ball from the take-off and jump and 2) attacking blow. In the experiment, the following parameters were measured: 1) the rate of motor reaction; 2) the accuracy of the throw, 3) the speed of the ball, 4) the total center of mass of the body; 4) comparison of all attempted shots performed by the participants in the experiment. The research was carried out during the volleyball training session. The technique was based on three levels of complexity.

We report a study of the composition of the soil in the Moscow region (the soils of the biology plant of the Moscow State Pedagogical University in the village of Pavlovskaya Sloboda of the Istrinsky district of the Moscow Region and the Yauza Station of the Yaroslavl direction of the Moscow Railway). The content of mobile forms of heavy metals (cadmium, lead, zinc, copper) in soils is evaluated using inversion voltammetric analysis (IVA). It is found that according to the degree of soil contamination, the metals under study form a series: cadmium > lead > zinc > copper. It can be assumed that the nature of the pollution is mainly aerogenic, i.e. atmospheric, which is convincingly proven by the data on the distribution of ions along the vertical profile of the investigated soils.

A modified scheme for preparation of a widely used reagent for immunofluorescence analysis, an isothiocyanate derivative of diethylenetriamine tetraacetic acid, is proposed. Certain stages of the compound preparation are optimized and the product yield is significantly increased (up to 70%). The developed scheme allows one not to apply an additional stage of the isothiocyanate derivative purification using preparative chromatography.

We consider eco-psychology of people in the conditions of a mega-polis and an eco-polis. It is shown how the problems of the city and its ecology affect human mentality and behavior. Attention is paid to the issues of the positive environment formation in an eco-polis. The ecological environment of a mega-polis and an eco-polis are compared. The term ‘eco-polis’ is considered as an environmental city of the future being designed and created at the present day.

We analyze the use of modern information and communication systems and technologies in the training of students at the Moscow region State University. The practical experience in the application of information and communication technologies in the educational process is generalized in order to improve the quality of the training of students and the effectiveness of the professional activity of a teacher. The analysis makes it possible to point out the main problems of practical use of modern information and communication technologies in the training of students.

In recent years, due to the development in various sectors of the economy and the implementation of ongoing economic and infrastructural projects, the changes in the natural and geographical environment on the northeastern slope of the mountain geosystem of the Greater Caucasus have caused some ecogeographic problems. The paper reviews the results of changes of varying degree related to closer population living, over a long historical period, on favorable hypsometric territories at a height of 200-500 m. The scientific foundations of the measures necessary to optimize the ecogeographical problems that have arisen as a result of intensive development of the territory are indicated, including in water basins, in the atmosphere, and in soils and vegetation cover.

We present the results of the analysis of the spatial distribution of the morphometric parameters and define indicators of ecological and geomorphological stresses of geosystems on their basis within the southern slope of the Greater Caucasus in the territory between the Dashagilchay - Girdimanchay rivers. Intensive development of mountain areas leads to a sharp degradation of unstable mountain geo-complexes, which requires a comprehensive study and identification of the patterns of the formation of mountain landscapes.

The paper analyzes the main approaches to solving the problem of waste disposal in Moscow. The problem of waste disposal is currently one of the most actual environmental problems in Moscow. The solution of this problem is carried out mainly through the disposal of waste. In recent years, programs have been implemented based on autorecycling and hydroseparation. Programs of autorecycling and hydroseparation cannot fundamentally solve the problem of disposal of waste that is currently produced in the city. The problem must be addressed using an integrated approach. Methods of disposal shall be provided at the stage of manufacture of the goods.
