Eco-Geophysical and Geoecological Factors in Assessing the State of the Geological Environment Based on the Analysis of Spatial Databases of the Territory of the Republic of North Ossetia–Alania

The article considers the main sources of pollutionin the territory of the Republic of North Ossetia–Alania. A study of environmental geophysical factors in the city of Vladikavkaz was carried out at 126 points; indicators of noise pollution, electric fields and the level of gamma radiation were measured. A geoaccumulation index of heavy metals in soils and indices of carcinogenic and non-carcinogenic risks were calculated and corresponding maps were constructed. The obtained data supporting a high level of carcinogenic risk are consistent with a high level of cancer morbidity in the city, which indicates a close relationship between morbidity and the carcinogenic risk index. It has been determined that emissions from road transport are greater by an order of magnitude than stationary sources emissions, while there is a steady trend towards an increase in air pollution as a result of the increasing negative impact of motor vehicle emissions. It has been established that the most hazardous way for heavy metals to enter the human body from the soil is by inhalation. It has been determined that in areas where environmental pollution with heavy metals is higher, cancer morbidity is also higher

Investigation of ecogeophysical factors of the environment of Vladikavkaz

A study of ecogeophysical factors of the environment in Vladikavkaz was carried out at 126 points: indicators of noise pollution, electric fields and the level of gamma radiation were measured. The noise level was determined with the help of noise and vibration meter Ekogeofizika-110A of the domestic company Oktava. It has been defined that the population of Vladikavkaz is subjected to a significant noise period of time, which exceeds the permissible level, which can negatively affect the health of citizens. Measurements of gamma radiation level were made using a gamma radiation dosimeter DBGA-OCHA. According to the obtained data, the population of Vladikavkaz is exposed to the gamma radiation in the range of 0.05–0.18 µSv/h and with an average value of 0.11 µSv/h, which is below the maximum permissible level. In order to study the electric fields, the measurements were carried out by the electric field meter IEP-05. The electric field strength reached up to 1400 V/m at individual measurement points, at an acceptable level of 800 V/m; this indicator exceeds the maximum permissible values
