Abstract
Environmental monitoring of physical pollution of territories at the stage of pre-project work
Incoming article date: 13.02.2023Environmental monitoring of physical pollution of territories is carried out in various regions of the Russian Federation and abroad. Thus, the influence of, for example, radio frequency radiation on human health and ecosystems has been established. In this regard, the study of low-frequency fields of electric fields at the stage of pre-design work is relevant. The purpose of the study was to study the electric field strength (E,V/m) on the land allocated for horticulture in the DNT ""Luch"" of the Sredneakhtubinsky district of the Volgograd region in September 2021. Research objectives: measurement of the electric field strength; analysis of the obtained results; study of anthropogenic and natural sources of physical pollution of the territory; discussion of the obtained results. Materials and methods. The study of the electric field strength on a land plot allocated for gardening was carried out using a PZ-34 electromagnetic field parameter meter (Russia), which is registered in the state register of measurement systems (No. 64925-16) and is popular among other researchers. Research results. 30 measurements were taken. The data obtained (E=1.16+0.11 (V/m)) did not exceed the standards for residential areas. The median values of the electric field strength were 10-17 times higher than the median values of the studied indicator in comparison with similar rural areas in other countries of the world. Conclusion. These facts may indicate low-frequency pollution of the territory of a mixed type: an anthropogenic factor (highways, high-voltage power lines), a natural factor: a possible hidden mineral deposit, as a product of the post-volcanic activity of an ancient underground volcano in the Volga steppe zone, which requires further large-scale geological exploration of the study area and possible change in the status of the land.
