In this study, a total of 30 points along a track line of approximately10 km in downstream of Mazra’eh copper mine (Ahar-East Azarbaijan) covered with a mixture of transferredtailings and bed sediments of Mazra’eh seasonal river were selected. The composite samplings were carriedout fromsoils at depths of 0-10, 10-30 and 30-60 cmand fromsurficial sediments. In addition, six non-coveredpoints (controls) with minimum distance from the sampling points were selected. The total concentrations ofcopper in surficial sediments as well as soils were determined using aqua regia method. Then, the relationshipsbetween these concentrations and soil properties were assessed. The results showed very high concentrationsof copper (1116 mg kg-1, on average) in the surficial sediments. The concentrations of copper in the soil depthsof 0-10, 10-30 and 30-60 cm were 105, 86.4 and 79.8 mg kg-1, respectively. Based on results, 13% of 0-10 cmsoils, all of 10-30 cm soils and 57% of 30-60 cm soils were very contaminated, medium contaminated and lowcontaminated, compared to controls (48.4 mg kg-1, on average for three depths), respectively. Soil copperconcentration showed significant positive correlations with surficial sediment copper concentration, thicknessof surficial sediment and soil cation exchange capacity (CEC) in all three depths of the studied soils.}, keywords = {Copper mine,Mobility factor,Surficial sediments,Tailings dam}, title_fa = {روابط آلودگی مس با ویژگی های خاکهای پایین دست معدن مس مزرعه (اهر-آذربایجان شرقی)}, abstract_fa = {}, keywords_fa = {رسوبات سطحی,سد مواد باطله,فاکتور تحرک,معدن مس}, url = {https://water-soil.tabrizu.ac.ir/article_5520.html}, eprint = {https://water-soil.tabrizu.ac.ir/article_5520_e5e97767930769e580f28f7094529011.pdf} }
