Abstract
Soil pollution by heavy metals is a frequently encountered issue at many hazardous waste sites. Mining operations generate a significant volume of inert materials and waste, which are then deposited on the surface. The abandoned mine of Sidi Kambar could pose a major problem due to the potentially high concentrations of potentially toxic elements present in its discharges. To assess the level of soil contamination near the abandoned Pb-Zn mine in Sidi Kambar, heavy metal concentrations were determined in soil samples taken from the Essouk River. The results of the monitoring of the spatial evolution of metal trace elements (Zn, Pb, and Fe) during the month of February 2023 in the soil of this watercourse show that metal content is growing in the order: Pb > Zn > Fe. They also exhibit variations across the ten (10) study stations, ranging from 102.7 to 141.2 for Zn, 1918.8 to 3150.4 for Fe, and 115.5 to 134.5 for Pb. The degree and sources of contamination were determined by calculating metal contamination indices: the geoaccumulation index, the contamination factor, the degree of contamination, and the pollution load index. High levels of contamination have been observed around spills of mining waste, resulting in high levels of contamination. However, no cases of extremely high or ultra-high contamination were found in the mining fields of the studied area. Therefore, human activities could be the main factor in abandoned Pb/Zn mining areas.
期刊介绍：
Eurasian Soil Science publishes original research papers on global and regional studies discussing both theoretical and experimental problems of genesis, geography, physics, chemistry, biology, fertility, management, conservation, and remediation of soils. Special sections are devoted to current news in the life of the International and Russian soil science societies and to the history of soil sciences.
Since 2000, the journal Agricultural Chemistry, the English version of the journal of the Russian Academy of Sciences Agrokhimiya, has been merged into the journal Eurasian Soil Science and is no longer published as a separate title.
