Concentrations and depth distribution of the total content and forms of trace elements in fluvisols with different technogenic load were studied. Alluvial soddy saturated soil of the Oka river (Moscow region) was studied as soils with a low technogenic load. Increased concentrations of metals in the background fluvisol are observed in the riverbed floodplain, which indicates their entry during floods. In the fluvisol near the industrial center, the concentration of trace elements may not exceed hygiene standards due to their intensive removal from the landscape. Agricultural use can cause uniform depth distribution of total and mobile forms of the elements. Thus, the concentrations, depth distribution and speciation of trace elements in fluvisols with different technogenic loads depend not only on the scale of this load but also on the soil properties and the ratio of the processes of element input to and removal from the soils.

研究了不同工艺负荷下流水溶胶中微量元素总含量和形态的浓度和深度分布。奥卡河（莫斯科地区）的冲积泥质饱和土壤被研究为具有低技术负荷的土壤。在河床漫滩中观察到背景河流中的金属浓度增加，这表明它们是在洪水期间进入的。在靠近工业中心的河流中，微量元素的浓度可能不会超过卫生标准，因为它们被大量地从景观中去除。农业使用可以导致元素的总形式和移动形式的均匀深度分布。因此，浓度，
