Resumo

Natural and anthropogenic factors determining the distribution and accumulation features of Pb, Cu, Zn, Cr, Ni, Cd, Mn, and As in the soil–plant system of the Don River estuary and the northern and southern Russian coasts of Taganrog Bay estuary have been studied. High mobility of Cu, Zn, Pb, and Cd has been revealed in alluvial soils. This is confirmed by the significant bioavailability of Cu, Zn, and, to a lesser degree, Cd and the technophily of Pb, which are accumulated in tissues of macrophytic plants. Statistically significant positive correlations have been found between the mobile forms of Cu, Zn, Cd, and Mn in the soil and the accumulation of metals in plants. Impact zones with increased metal contents in aquatic ecosystems can be revealed by bioindication from the morphofunctional parameters of macrophytic plants (with Typha L. as an example).
