The biological activity of soils is an essential parameter of their ecological status. The anthropogenic Heavy Metals (HMs) disturb the normal functioning of soil biota and, hence, the entire soil system. The aim of this work was to estimate the toxicity of loosely bound HM compounds in Haplic Chernozem using parameters of cellulose-degrading and urease activities. Contamination of Haplic Chernozem with Zn, Cd, Cu and Pb enlarged the group of mobile (loosely bound to soil) metal compounds, which includes exchangeable, complexed and specifically sorbed compounds of HMs. The increase of mobile HM forms content in soil inhibited the cellulose-degrading and urease activities after 30 days of the input of metal into the soil. A decrease in the toxic effect of metals on the studied parameters mainly occurred in the next 30 days. It was found that all HM forms similarly affected biological activity parameters. During two months from the moment of soil contamination with HMs, their toxic effect on cellulose-degrading and urease activities decreased. According to the degree of inhibition of biological activity in Haplic Chernozem, the studied metals formed the following series: Cd >Pb > Zn > Cu.

“…Loosely bound compounds are the most important group of metals for the ecological point of view, as it enters plants and dispersed to environments. Hazardous ecological consequences of soil contamination with metals are related to these compounds [ [1] , [2] , [3] ]. The studies of the loosely bound compounds can assess not only the supply of nutrients to plants but also the degree of mobility and availability of toxic elements to living organisms, which is important to observe under anthropogenic pollution.…”

“…where C i is the total content of metal i in soil, and C b is the background value [15]. Four categories of soil pollution were defined according to Zc values [46]: acceptable (<16), moderately hazardous (16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32), hazardous , and extremely hazardous (>128).…”

“…The study of the mechanisms of resistance of coastal-aquatic vegetation, including hydrophytes, to pollution of aquatic ecosystems at the land-sea margin is becoming increasingly important. It has been noted that the Typhaceae family can grow in habitats with high PTE levels [11][12][13][14][15][16][17][18][19]. PTE take-up is a very complicated process, including element uptake from soil solution to inside cells of roots [20].…”

“…High concentrations of PTEs in Typha can be accumulated from the water column and from soils demonstrating the usefulness of Typha plants as biomonitors for estuarine systems [27]. Bioaccumulation of PTE by the plants in changing environmental conditions results in transformations at the morphological and cellular levels providing the resistance and possible adaptation of the plants to various ecological conditions [14,15,[28][29][30][31].…”

The aim of this study is to investigate the adaptation of two species of cattail Typha australis Schum. and Thonn. and Typha laxmannii Lepech. based on analysis of the morphological and anatomical features of their vegetative and generative organs to soil pollution with potentially toxic elements (PTE) in the riparian zones of the sea edge of the Don River delta (Southern Russia). Both species of the cattail are able to accumulate high concentrations of Ni, Zn, Cd, Pb and can be used for phytoremediation of polluted territories. The pattern of PTE accumulation in hydrophytes has changed on polluted soils of coastal areas from roots/rhizomes > inflorescences > stems to roots/rhizomes > stems ≥ inflorescences. The comparative morphological and anatomical analysis showed a statistically significant effect of the environmental stress factor by the type of proliferation in T. australis, and species T. laxmannii was visually in a depressed, deformed state with mass manifestations of hypogenesis. These deformations should be considered, on one hand, as adaptive, but on the other, as pathological changes in the structure of the spikes of the cattails. Light-optical and electron microscopic studies have shown that the degree and nature of ultrastructural changes in cattails at the same level of soil pollution are different and most expressed in the assimilation tissue of leaves. However, these changes were destructive for T. australis, but for T. laxmannii, these indicated a high level of adaptation to the prolonged technogenic impact of PTE.
