The article presents the results of assessing the element mobility (chemical elements and compounds) from the copper smelting slag recycling waste into brown forest soils (Haplic Cambisols) of the southern taiga district in Middle Urals, Russia. The copper smelting slag recycling waste was obtained by crushing the cast slag of the Sredneuralskiy Smelter ("technical sand") followed by flotation extraction of copper concentrate. The investigations were carried out in two forest types, distinguished according to the principles of the genetic forest typology, cowberry shrub pine forest and berry pine forest with linden, and the corresponding clear-cuttings. We conducted the experiment in the autumn before the snow cover was established in two variants: (i) we evenly scattered 1 kg of waste on meter sample plots; (ii) we weighed the "technical sand" by 100 g, packed it in non-woven material and buried it in the soil to a depth of 7-10 cm. Two years later, we dug up the bags with waste and weighed them. The analyses were performed by inductively coupled plasma mass spectrometry using Elan-9000 ICP mass spectrometer. As a result of the research, it was found that waste loses 11% mass over 2 years of being in forest soils. The content of Zn, As, Cd, and Se changes most strongly. The difference in the degree of element migration from the "technical sand" to the brown forest soils of the two forest types and clear-cuttings was revealed. The study of the effect of technogenic waste on the dominant and diagnostic species of grassy vegetation in the selected forest ecosystems of the Middle Urals was carried out. There was no negative effect on the qualitative composition of the grassy layer of two forest types and their clear-cuttings after 1 year after a single surface application of mineral waste at a concentration of 1 kg/m.
本文介绍了评估俄罗斯中乌拉尔南部南部泰加林地区棕色森林土壤（典型暗棕色森林土）中铜冶炼渣回收废物元素（化学元素和化合物）迁移能力的结果。铜冶炼渣回收废物是通过粉碎斯捷尔日涅尔冶炼厂的铸渣（“技术砂”）并随后进行浮选提取铜精矿获得的。研究在两种森林类型中进行，根据遗传森林分类学的原则进行区分，分别为越桔灌丛松林和含有椴树的浆果松林，以及相应的皆伐林。我们在两种变例下于秋天下雪前在 1 米样方上进行实验：（i）我们均匀地在样方上撒 1 公斤废物；（ii）我们称取 100 克“技术砂”，将其装入无纺材料中并埋入土壤中 7-10 厘米深。两年后，我们挖出装有废物的袋子并称重。分析使用电感耦合等离子体质谱法（ICP-MS）通过 Elan-9000 ICP 质谱仪进行。研究结果表明，废物在森林土壤中 2 年内损失了 11%的质量。Zn、As、Cd 和 Se 的含量变化最大。揭示了“技术砂”中元素向两种森林类型和皆伐林的棕色森林土壤中迁移程度的差异。研究了中乌拉尔选定森林生态系统中矿质废物对优势和诊断种草本植被的影响。在单一表面施用量为 1 公斤/米时，经过 1 年，两种森林类型及其皆伐林的草本层质量组成没有受到负面影响。
