METHODOLOGICAL APPROACHES TO GEO-ECOLOGICAL ASSESSMENT OF OIL-CONTAMINATED LANDS

 

Annotation. The article is devoted to the urgent problem of geoecological assessment of lands contaminated with oil and petroleum products as a result of the activities of the oil extraction and oil transport complexes. The main sources of pollution, including emergency spills during transportation, and their negative impact on soil ecosystems are analyzed. A systematic review and comparative analysis of modern methods for assessing oil-contaminated soils, including chemical, biological, geophysical, and remote methods, has been carried out. Their advantages, disadvantages, and areas of application are identified. Using VOSviewer software, a cluster analysis of publication keywords was performed, which revealed two main interconnected areas of research: cleanup technologies, practical ecology (and microbiological-genetic aspects of pollutant degradation). As a promising direction, an innovative method for assessing phytotoxicity based on the growth efficiency of test plants based on calculating the fractal dimension of the green biomass of plant leaves, implemented in the form of an author’s computer program, is proposed. This approach allows for rapid and non-invasive assessment of soil phytotoxicity and the effectiveness of reclamation measures.

Keywords: oil contamination, geoecological assessment, cluster analysis, reclamation, phytotoxicity, bioindication, fractal analysis, fractal dimension.
