Features of Heavy Metal Contamination of Agricultural Soils in the Kursk Region of Russia and Economic Assessment of Restoration

Abstract

Kursk region of Russia has unique fertile soils. Heavy metals are among the factors that pollute the soil. The article is devoted to the study of the spatial distribution of heavy metals in soils. The relevance of the study is that the value of the soil is determined by its value for obtaining environmentally friendly agricultural products. Data on the content of heavy metals in the soil can prevent intensive cultivation of crops. The task of the work is to identify heavy metals that predominate in the soils of various landscapes of the Kursk region. The assessment of soil contamination with chemical elements was carried out in the course of geo-ecological studies of black earth soils in the Kursk region of Russia. The selected soil samples were examined by semi-quantitative spectral analysis. The results obtained were subjected to statistical processing. It was found that cobalt is the main pollutant in the vast majority of sampling points. In other zones, molybdenum, lead, zinc, and chromium predominate in approximately equal amounts. Soils in the surveyed area belong to the permissible category of contamination with chemical elements. Soil remediation should be applied in local areas.

Assessment of heavy metals concentrations intropical agroecosystem (Wakwa,Adamawa,Cameroon): An Index Analysis Approach

“…This could explain why many HM are found to be greater than some reference values and other study in site Wk 4 . Tomakov and Tomakov, (2021) reported that Pb has a cumulative effect and causes damage to the central and peripheral nervous system; human health is in danger through food chain. Excessive pollution of site Wk 4 could affect the marine ecosystem of the downstream Lake.…”

“…For the case study Mo concentrations are very high. Knowing that Mo belongs to the second class of danger and has a General toxic, carcinogenic and mutagenic effect at significant concentrations (Tomakov and Tomakov, 2021); it can be dangerous for human and environment. In addition, a diet rich in molybdenum caused deformities in the joints of the extremities of cattle; so, this high concentration in molybdenum exposed also animals present in the agroecosystem.…”

“…In the study carried out by Defarge et al, (2017) Machender et al (2013). It belongs to the third class of danger and causes at significant concentrations of General toxic damage to internal organs, nervous and circulatory systems (Tomakov and Tomakov, 2021).…”

Investigation of the factors forming the attitude of construction workers to unsafe behavior in work

“…Охрана труда является важной обязанностью работодателя по обеспечению государственных нормативных требований охраны труда и одним из важнейших приоритетов деятельности любых организаций всех форм собственности. Однако на предприятиях различных сфер экономики Курской области производственный травматизм продолжает оставаться одной из актуальных социально-экономических проблем, поскольку имеют место несчастные случаи со смертельным исходом [1,2]. При многоотраслевом укладе экономики региона наиболее высокий уровень производственного травматизма со смертельным исходом регистрируется в строительстве [3,4].…”

“…Подавляющее большинство причин производственного травматизма на предприятиях региона случается по вине руководителей и самих работников -они не в полной мере выполняют возложенные на них функции и обязанности [1,2].…”
