The estuarine region of the Don River is a unique area occupied by a complex natural-technogenic system of interacting natural, urbanized, and agrarian ecosystems. The aim of this work was to study the level and degree of mobility of heavy metals (HMs) in the soil-plant system and to perform bioindication observations in the Don River estuarine region and the Russian sector of the Taganrog Bay coast. The soil cover is represented by following soils types: Fluvisols, Haplic Chernozem, Arenosol, Solonchak. The follo...

The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of heavy metals (HM) in soils and plants of the estuarine ecosystems of the Don river and the Taganrog bay coast (Russian Federation). The soil cover is represented by following soils types: Fluvisols, Haplic Chernozem, Arenosol, Solonchak. The following higher plants were sampled: Phragmites australis Cav., Typha angustifolia L., Carex riparia Curtis, Cichorium intybus L., Bolboschoen...

The determination of the geochemical fractions of heavy metals in soils of technogenic landscapes is a key issue in the study of their mobility. The current study aims to investigate of the accumulation and mobility of Cu in soils adjacent to the Karabash copper smelter at South Urals, Russia. Studies were performed in the plume zone of the Karabash smelter and in the floodplains of Ryzhii Brook and Sak-Egla River for the surface layer of soil (0-5 cm). The level of Cu pollution by soil located at a distance from ...
