Heavy metals are one of the leading environmental pollutants that are hazardous to the health of humans, soils, plants, and aquatic life. This study investigated the potential of Athyrium filix-femina, Ludwigia peruviana, and Sphagneticola trilobata for phytoextraction of Al, Ag, Cd, Cr, Ga, and Sr. To evaluate the heavy metal uptake by the plants, a pot experiment was conducted using uncontaminated soil mixed with a heavy metal solution. At the end of thirty days of planting, the bioconcentration and translocation factors were calculated. Cd accumulated to a greater degree in the shoots of A. filix-femina and L. peruviana than in their roots (8% and 12% respectively). Conversely, S. trilobata accumulated 27% more Cd in its roots than in its shoots. In all three plant species, roots had significantly higher heavy metal concentrations than shoots. These findings demonstrate that L. peruviana, A. filix-femina, and S. trilobata have high potential for phytoextraction and bioaccumulation of Cd, Sr, Ag, and Ga. The herbaceous nature of these plants, coupled with their deep roots and rapid growth rates, make them promising candidates for phytoremediation in heavy metal-contaminated soils.

The phosphogypsum dumps are one of the most toxic solid wastes of phosphoric acid, phosphate and phosphorus fertilizers manufacturing enterprises. In the article the possibility of remodeling of phosphogypsum dumps with using the Poaceae family herbaceous plants seeding was considered. On the basis of determination of growth parameters as well as sulfur and fluorine ions accumulation in the plants, the expediency of the dumps surface covering with a ground-covering mixture consisting of sand and sediment of wastewater in the amount of 10% or 20% by weight is established. In the dumps Bromus inermis Leyss., Dactylis glomerata L., Elytrigia pseudocaesia (Pacz.) Procud., Festuca arundinacea L. and Festuca altissima L. are the most suitable plants for cultivation.

This paper presents the results of study on heavy metals in soil and in herbaceous plants in selected pine forests in Słowiński National Park. The heavy metals, such as Zn, Cu, Mn and Fe were studied. Concentrations of zinc in tested soil are strongly and very strongly related to manganese and copper content (r = 0.57 do r = 0.98, p < 0.05). Moreover, the soil moistening has vital impact on copper content in the plants of the ground cover. It was also found that moss in comparison to other forest plants captures higher volume of zinc and copper. The content of the above mentioned metals in the plants of dry coniferous forests (Bs), fresh coniferous forests (Bśw) and humid coniferous forests (Bw) of the ground cover constitute the following decreasing series: Mn(438.1) > Fe(98.6) > Zn(35.2) > Cu(3.5).
