Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The ecological situation continues to remain very tense in the Turkistan region, which is associated with the consequences of the extensive economic activity of the past decades with the use of outdated technologies, as well as the urbanization of the city of Shymkent.The aim: to determine the impact of industrial pollution on the state of soils in technogenic landscapes.Objectives: (1) to identify polluted industrial areas in the Turkistan region; (2) to distinguish the primary pollutants emitted from industries in the Turkistan region; and (3) to assess the state of soil in industrial areas of the Turkistan region.To obtain a qualitative analysis of the soil, the method of atomic absorption spectrometry was used, then the method of a scanning electron microscope was used to obtain enlarged images and morphology of the soil.The scanning electron microscope made it possible to obtain quantitative data on the elements contained in soils.The examined soil specimens were found to have very low concentrations of metals, such as aluminum (Al), silicon (Si), phosphorus (P), sulfur (S), and titanium (Ti).The primary pollutants (Pb, Zn, Cu, and Cd) were determined.These metals were present in concentrations that significantly exceeded the regional background values.
