Abstract
The article presents an assessment of technogenic impact on the development of gas fields in the south-west of the Aral Sea regions. As a result of monitoring activities and conducted scientific research (2011-2012), a significant amount of data on the state of the natural environment in this region has been accumulated and data on the chemical composition of soils are presented. However, the processing of the received information consists mainly in comparing data on pollutants with the maximum permissible concentration (MPC). In particular, the dynamics of long-term anthropogenic impact on soil quality is determined by the soil/rock formations processes. Examples of technogenic impact of the Ustyurt gas-chemical complex on the environment are given. The scientific novelty of the work lies in taking into account the spatial dynamics of soil pollution (analysis of the dynamics of the chemical composition of soils depending on the distance from the source of pollution), the proposed method of gradient indication of the degree of pollution, based on a quantitative assessment of the spatial dynamics of pollution, the assessment of the summation effect using a normative characteristic - total concentration homogeneous pollutants.
