Introduction. The relevance of the work for preventive medicine is due to the need to assess the impact of climate aridity on the hygienic safety of drinking water. The aim of the work is to determine the influence of the degree of aridity of the arid regions of Russia on the hygienic safety of drinking water prepared from surface water sources. Materials and methods. The objects of the study are the water of small rivers located in the arid regions of the Saratov Region and the Republic of Bashkortostan. The content of pollutants in water was determined by atomic absorption spectrometry, spectrophotometry, and potentiometry. Satellite images for the implementation of remote sensing of the Earth are obtained in the geoinformation catalogue earthexplorer.usgs.gov. Image processing and mapping of the studied territories was carried out using the QGIS program, version 3.12.3. Results. Using the method of remote sensing of the Earth, it was revealed for the first time that the low-arid regions of the Republic of Bashkortostan correspond to positive NDMI values. In contrast, the areas of the Saratov region are characterized by negative NDMI values. For the first time, a statistically significant correlation has been established between the hygienic hazard caused by polluting chemicals in water, typical for arid territories and the change in the aridity index NDMI. Biogenic nitrogen, iron, and manganese make the most significant contribution to the formation of the non-carcinogenic danger of small river waters in the conditions of climate warming. Conclusion. We have shown for the first time using the remote sensing method of the Earth that low-arid regions of the Republic of Bashkortostan correspond to low positive values of the aridity index NDMI than for the areas of the Saratov region characterized by negative NDMI values. For the first time, a correlation was established between an increase in the degree of aridity of arid areas of Russia and an increase in non-carcinogenic health risk due to the use of drinking water prepared from surface water sources.

The paper deals with the analysis of bioindicator opportunities of hydrobionts of various systematic categories that helps to assess and forecast anthropogenic pollution of the Belaya River (the top and average currents) during environmental monitoring of natural waters of the Republic of Bashkortostan. Hydrobionts were collected and the occurrence analysis (in unit shares) of 30 species of invertebrate animals from groups Pyramidelloida, Littorinimorpha, Pulmonata, Plecoptera, Ephemeroptera, Trichoptera and 12 species of the highest water vegetation was carried out from 2005 to 2017 in regions of 10 state water posts on the Belaya River. The data from annual State reports on the average annual content of compounds of manganese, nickel and iron, oil products, phenols, nitrogen ammoniyny, copper and zincum were used as hydrochemical parameters during the research. The reliable correlation between some water organisms with chemicals and their connections was defined in the water of the Belaya River. The author also constructs for the first time an indicator range of hydrobionts on decrease extent in their response to the chemicals content in the studied water. Similar approach can be used for recommendations development about the use of biological analyses while identifying the chemicals influencing water fauna and flora.

The story is now familiar. In the late 1960s humanity finally saw photographic evidence of the Earth in space for the first time. According to this narrative, the impact of such images in the consolidation of a planetary consciousness is yet to be matched. This book tells a different story. It argues that this narrative has failed to account for the vertiginous global imagination underpinning the media and film culture of the late nineteenth century and beyond. Panoramas, giant globes, world exhibitions, photography and stereography: all promoted and hinged on the idea of a world made whole and newly visible. When it emerged, cinema did not simply contribute to this effervescent globalism so much as become its most significant and enduring manifestation. Planetary Cinema proposes that an exploration of that media culture can help us understand contemporary planetary imaginaries in times of environmental collapse. Engaging with a variety of media, genres and texts, the book sits at the intersection of film/media history and theory/philosophy, and it claims that we need this combined approach and expansive textual focus in order to understand the way we see the world.

The Munku-Sardyk (Eastern Sayan) glacier has been described and studied for more than 100 years. The first largest glacier of Peretolchina was studied in the most detailed detail. Radde's second-largest glacier is much weaker. Monitoring of surface characteristics of the Radde glacier by ground methods and using data of remote sensing of the Earth (RSE) has been carried out since 2006. In 2018, georadar profiling of this glacier was performed for the first time. As a result, it was possible not only to clarify its surface characteristics, but also to assess the power of the ice and the internal structure (a layer of firn, ice, bed). According to the RSE, its geometric changes have been revealed. Over 120 years, the open part of the Radde Glacier has shrunk from 0.4 to 0.09 km2, and the length from 1 to 0.4 km. It also revealed the division of the glacier into two parts and the intensive reservation of the bottom of the main part of the tongue by surface moraines and the formation of a glacial lake on the glacier itself in the lower part of the second half. Radar research using the Oko-2 georadar, allowed to determine the volume of ice of this glacier 0.003 km3 and the greatest thickness of the main ice body 42 m. The main glacier flows down from the Eskadriliy top, 3168 m, to the north, flows on the cross-bar and from it turns to the northeast, and at the bottom of the kar will continue to flow north again.

<p>Groundwater is the main source of drinking water in the Nile Delta. Unfortunately, it might be polluted by seepage from polluted streams. This study was carried out to investigate the possible measures  to  protect groundwater  in the Nile delta aquifer using a numerical model (MT3DMS - Mass Transport 3-Dimension Multi-Species). The sources of groundwater contamination were identified and the total dissolved solids (TDS) was taken as an indicator for the contamination. Different strategies were investigated for mitigating the impact of polluted water: i) allocating polluted drains and canals in lower permeability layers; ii)  installing cut-off walls in the polluted drains, and finally, iii) using lining materials in polluted drains and canals. Results indicated these measures effective to mitigate the groundwater pollution. In particular, the cut-off wall was effective for contamination reduction in shallow aquifers, whereas it had no effect in the deep aquifer, while lining materials in polluted drains and canals were able to prevent contamination and to protect the freshwater in the aquifers.  It is worth mentioning that this study was partially supported by a bilateral project between ASRT (Egypt) and CNR (Italy).</p><p> </p><p> </p>

Abstract The authors examine the impact of the development of image-based remote sensing systems on the activities of state administrations in the cartographic production and making of geographical information publicly available in the Eastern Bloc countries. A convergence of cartography, secrecy, and power occurred during the Cold War. Through investigation of facts relevant to the acquisition image data of the Earth surface performed by the USA and the USSR, it aims to examine the key questions of why the logic behind the development of cartography in the Eastern Bloc countries after World War II was distorted. The lack of logic was reflected in the fact that the amount of information actually presented on maps decreased with an increase in the information about the surface of the Earth acquired by the means of remote sensing systems. It was suggested that image data in the member states of the Eastern Bloc, in spite of their restricted use and a drop in the informational value of maps, was the main factor behind the creation, detail, and geometric accuracy of civilian maps. Proving this thesis involved analyzing the correlations between the achievements in the field of remote sensing and the quality of maps developed during the Cold War in the Eastern Bloc states.

In mining operations, including those in the Republic of Bashkortostan, the health of workers is not good, due to the impact of adverse occupational factors, as evidenced by the level of occupational morbidity in the industry. In this regard, the solution of issues of workers’ health protection is the most significant in occupational health. The working conditions of male workers of the main underground occupations of the enterprise producing copper-zinc ores have been studied. We have evaluated the dependence of the identified diseases on occupational factors and findings on occupational morbidity between 1997 and 2018. The results of the studies indicate a complex of adverse factors affecting the workers of underground occupations that determine the evels and structure of work-related morbidity, including occupational, the main forms of which are vibrational disease, sensorineural hearing loss, diseases of the musculoskeletal and respiratory systems. Diseases of the musculoskeletal system, upper respiratory tract and arterial hypertension with a risk level from «medium» to «very high» are regarded to be work-related. The greatest number of cases of occupational morbidity among the underground occupations has been established among drifters, fasteners, and mining technicians. Preventive measures aimed at modifying occupational factors and improving medical support for enterprise workers have been developed.
