Soils located in the Jaworznicko-Chrzanowski Industrial District in Southern Poland have been contaminated with heavy metals due to mining and processing of non-ferrous metals. The aim ofthe study was to evaluate the uptake of copper, cadmium, zinc and lead by vegetation on fallow land as a function of soil parameters and species composition of pla...

... this reason, it should be stated that the tested soils are not contaminated with this element [26]. The mean value amounted to 19.73 mg kg-1 (Table 2) with the standard for soils in Poland <100 mg kg_1 [32]. Really high values of Cu soil content, such as 8087 mg kg*' have been reported from the area near a Cu smelter in Slovakia [33]. ...

... in the study area were considerably con- taminated with lead [25]. The average lead content was 204.24 mg kgTl (Table 2), while the norm for Poland is <100 mg kg", however, the contamination of soils in the vicinity of smelters can be much higher, eg. in northern France 4480 mg kgI [34] or the Czech Republic 4660 mg kg-l [35]. Very high containination with lead reaching even the value of 22265 mg kg" was found in the old heaps nearby [13]. ...

... High values of PTEs were observed in the soil and dandelion sampled, in a locality with high traffic density situated in the Czech Republic [76]. Zarzycki and Petryk [77] indicated that influencing the accumulation of PTEs in plants is determined by different factors which depend on the metal types and main soil parameters. According to their results, factors affecting bioaccumulation of PTEs included organic matter and soil reactions for cadmium, organic matter and electrical conductivity for lead and pH for copper. ...
This study examined the use of an artificial soil substrate in a mine waste reclamation area and its effect on plant metabolic functions. Research was conducted by determining the relationship between the plants’ biochemical features and the properties of plant growth medium derived from post-flotation coal waste, sewage sludge, crushed stone and fly ash on the surface of the mine waste disposal area. Trees and shrubs were established on the material and allowed to grow for eight years. The study determined that the applied plants and the naturally occurring Taraxacum officinale were suitable for physio-biochemical assessment, identification of derelict areas and reclamation purposes. An evaluation of a soil substrate applied to post-mining areas indicated that it was beneficial for plant growth since it activated the metabolic functions of herbaceous plants, shrubs, and trees. The study showed that soil substrate can be targeted to improve plant stress tolerance to potentially toxic elements (PTEs). These data suggest the potential for growth and slower susceptible response to Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn. It is possible that the constructed soil-substitute substrate (biosolid material) would be an effective reclamation treatment in areas where natural soil materials are polluted by PTEs. This observation may reflect a more efficient use of soil substrate released from the cycling of organic biogene pools, in accordance with the circular economy approach. In further studies related to land reclamation using sewage sludge amendments, it would be necessary to extend the research to other stress factors, such as salinity or water deficiency.
