In spite of enormous climatic differences between Burkina Faso and Germany, 20 species belong to the spontaneous flora of both countries, i.e. 1% of the flora of Burkina Faso and 0.15 % of the German flora. All of them are either ruderal and segetal species (16) or water and reed plants (4). All of the 16 ruderals/segetals are therophytes. From a recent point of view, most of the 20 species can be classified as cosmopolitan, because they cover three and more floristic zones, and/or at least three climatic zones, and/or are represented in at least three continents. Although Burkina Faso has a semi-arid climate, none of the species can be called a sclero- or xerophyte. Therefore, in Burkina Faso, all are more or less bound to habitats at least temporarily flooded or to humid soils. In Germany, however, the concerned ruderals, with one exception, are indicators of medium dry or dry habitats.

Abstract This paper is an attempt to answer the question whether common reed specimens growing in a particular habitat are genetically related. We have tried to identify groups of plants homogeneous in terms of habitat requirements and genetic similarity. Our objective was also to answer the question whether habitat conditions can affect the morphological characteristics of plants. Plants and bottom sediments were collected from 40 sites in central Poland, which differ in soil moisture and the degree of urbanization. Our research and analysis confirm the hypothesis to a certain extent. During the study, we identified three groups of plants homogeneous in terms of habitat and genetic factors (CVA model), which constitute 20% of all examined plants. In our opinion, further research is required on a larger population of P. australis in a larger area. The research revealed that plants growing in moist and wet areas were characterized by higher content of chlorophyll in leaves, longer stems as well as thicker and wider laminae. The common reed plants preferred anthropogenic substrates, which did not contain many nutrients, but were abundant in calcium. Our study confirmed the high tolerance of P. australis to soil salinity.

Abstract Among the numerous clean-up techniques for water treatment, sorption methods are widely used for the removal of trace metals. Phragmites australis is a macrophyte commonly used in constructed wetlands for water purification, and in the last decades, its use as biosorbent has attracted increasing attention. In view of a circularly economy approach, this study investigated improvement of trace metal removal by recycling the biomass of P. australis colonizing a constructed wetland, which operates as post-treatment of effluent wastewater from an activated sludge plant serving the textile industrial district of Prato (Italy). After the annual mowing of the reed plants, the biomass was dried and blended to derive a sustainable and eco-friendly biosorbent and its sorption capacity for Fe, Cu, and Zn was investigated comparing the batch system with the easier-to-handle column technique. The possibility of regeneration and reuse of the biosorbent was also evaluated. The biomaterial showed an interesting sorption capacity for Cu, Fe, and Zn, both in batch and in column experiments, especially for Fe ions. The immobilization of the biosorbent in column filters induced some improvement in the removal efficiency, and, in addition, this operation mode has the advantage of being much more suitable for practical applications than the batch process.

AbstractThe main aim of the presented work was to design and characterize the rhizofiltration system comprised of giant reed plants (Arundo donax L.), as species with phytoremediation potential, for the removal of cadmium as a toxic metal and zinc as an important microelement from model solutions spiked with radionuclides 109Cd and 65Zn. The possibility of effective cadmium and zinc rhizofiltration by the root system of giant reed plants under continuous flow conditions to achieve complete decontamination was confirmed. The highest 109Cd and 65Zn specific radioactivity (Bq g−1; dry mass) was found in case of plants located near the input of the solution into the system, whereby the radioactivity in the plants decreased in the direction of the solution flow within the system. On the other hand, gradual increasing of the concentration ratio [Cd]shoot: [Cd]root within this horizontal plants location was observed. Individual experiments showed that the efficiency of cadmium rhizofiltration decreased in the order of model solutions: synthetic wastewater (χ = 505 μS cm−1), deionized water (χ = 29.6 μS cm−1), 100 % Hoagland medium (χ = 1675 μS cm−1). The same results were also found in case of zinc rhizofiltration. For the description of cadmium and zinc rhizofiltration processes, the kinetic mathematical models widely applied for sorption processes under continuous flow conditions were successfully used.
