The paper considers the quality of land in the Astrakhan gas condensate field, including the background section of the field’s right bank and the structure of the Yelenovskaya license area of the Alexesevskoe deposit. At this stage, the critique says it was necessary to study the land cover in the gas condensate field, which accounts for the major sources of pollution (gas emissions at a gross rate of more than 100 tons per year). The structure, for its part, is dominated by emissions of acidic components and heavy metals. In the atmosphere, by contrast, the pollutants are partially transformed during the process of dry and wet deposition, and are subsequently absorbed by the soil and vegetation. The natural systems in the study area as a whole have been classified as semi-sandy terrain. The dominant vegetable the field contains is Lerch sagebrush. The document relates that the sampling was conducted during the growing season. It included a spectral analysis, which was carried out using the MCA-915 atomic absorption spectrometry device’s metal-graphite atomizer. According to the blueprint, the study showed that the ’background’ levels of certain trace elements in the soil are higher than those in the included technological areas: the right bank of the Astrakhan gas condensate field and the Yelenovskaya license area of the Alexesevskoe deposit. The commentary relates that the work was conducted to obtain timely data and to assess the background level of contamination at new sites in the landscape that are to undergo development.
