Assessment of soil pollution by petroleum products in cities of Karaganda region

Abstract

The article is devoted to assessing soil pollution with petroleum products in the cities of the Karaganda region and developing recommendations for its improvement. The environmental survey consisted of determining the content of petroleum products in the soil. The article presents the results of the analysis of 40 soil samples at 20 points in the city of Karaganda and 12 soil samples at 6 points in the city of Temirtau (at a depth of 0-5 and 5-20 cm) for the content of petroleum products. In addition, studies of the influence of roads on soil cover were carried out by analyzing soil samples taken near the Karaganda-Temirtau highway. Analysis of the results obtained showed that there is an almost universal excess of the maximum permissible concentration for petroleum products in the cities of the Karaganda region. The data obtained served as the basis for the recommendations proposed in the article for improving soil quality in the region under study.
