Silesia, i.e. the region of Poland which roughly dozen years ago was the most powerful industrial center in the country, is still struggling with residues of heavy metals, which are still present in the soil, water, mine waste dumps, and in the air – despite the fact that the number of polluting plants has been reduced and the use of appropriate filters, measures that have admittedly limited the emission of harmful substances into the environment, has been made obligatory. Metals will not disappear on their own; they are assimilated by plants, which animals feed on, and thus the “uninvited guests” are passed on. Humans are not spared by metals as well. The bare post-mining and post-production landfills around which housing estates are erected “endow” their residents with toxic dust. It turns out, however, that there are plant species which attach themselves to polluted areas and only exist where the concentration of heavy metals is high.

Ecological Reconstruction

This study aims at an ecological reconstruction, by means of macromycetes species, of the soils degraded by mining activities. To this end, samples of both soils and macromycetes from altitude mining waste dumps- resulted from the exploitation of iron and sulphur ores - have been collected and analyzed. The metal contents were determined by atomic spectrometry and the results were performed with Microsoft Excel, Origin and SPSS programs. The statistical study of the distribution of the metal content data among soil, substrate and macromycetes indicates an adequate correlation.

<p>Formation of soil anomalies in the operation area and the mine waste dumps results in an accumulation of heavy metals in plants, particularly if the physic-chemical properties of soil to facilitate the transition elements available to form them. We have proved that the individual organs of plants have a high capacity for accumulation of heavy metals, which allows us to recommend them for landscaping of dumps and heaps like plants, is actively contributing to the stabilization of technologically impaired environment under conditions of significant contamination.</p><p>It should be noted that an embodiment of the ecological stabilization of anthropogenic disturbed territory, on which the landfills and waste dumps of coal mines, is the introduction of individual plant micro associations that will be investigated in more detail in our further work on the technologically impaired phytomelioration territory.</p><p>Despite the fact that the overgrowth of dumps and heaps helps to improve the environmental situation, the number of pollutants, including heavy metals, hydrosphere and lithosphere remains high. This is due to the fact that the soil is able to deposit the contaminants and can be long-term source of secondary pollution.</p><p>We proved that that dumps and heaps of coal mines led to an increase of industrial hazard in the region based on the research of background radiation, heavy metals contamination in edaphotopes and vegetation. We also studied the species diversity, the stage of overgrowing, distribution of individuals in the vegetation communities in devastated landscapes. Analysis of our research results testified the necessity of protective trees shield within devastated landscapes to improve the ecological condition of industrial congested region and increasing the productivity of disturbed lands.</p>

Abstract The aim of this study was to determine the ecological characteristics of vascular plants colonizing serpentine mining waste dumps and quarries in Lower Silesia. The investigated flora was analyzed with regard to species composition, geographical-historical status, life forms, as well as selected ecological factors, such as light and trophic preferences, soil moisture and reaction, value of resistance to increased heavy metals content in the soil, seed dispersal modes and occurrence of mycorrhiza. There were 113 species of vascular plants, belonging to 28 families, found on seven sites in the study. The most numerous families were Asteraceae, Poaceae, Fabaceae and Caryophyllaceae. Only 13% of all plants recorded occurred on at least five of the study sites. The most numerous were species related to dry grassland communities, particularly of the Festuco-Brometea class, which included taxa endangered in the region of Lower Silesia: Avenula pratensis, Salvia pratensis, Festuca valesiaca. Apophytes dominated in the flora of the investigated communities. Hemicryptophytes were the most numerous group and therophytes were also abundant. The serpentine mining waste dumps and querries hosted heliophilous species which prefer mesic or dry habitats moderately poor in nutrients, featuring neutral soil reaction. On two study sites 30% of the flora composition consisted of species that tolerate an increased content of heavy metals in the soil. Anemochoric species were the most numerous with regard to types of seed dispersal. Species with an arbuscular type of mycorrhiza were definitely dominant in the flora of all the study sites, however, the number of nonmycorrhizal species was also relatively high. It was suggested that both the specific characteristics of the habitats from serpentine mining and the vegetation of adjacent areas had a major impact on the flora composition of the communities in the investigated sites.

Knowledge of tailings characteristics is required for utilisation and management purposes in the mining and construction industry. Tailings from the mine waste dumps at Itakpe iron ore mine were collected and analysed in the laboratory to determine their chemical and physical characteristics and these include; permeability, porosity, specific gravity, particle size distribution, chemical composition and bioavailability factor of element. Geochemical speciation with quantitative X-ray powder diffraction was used to evaluate the chemical and mineral composition of Itakpe iron ore tailings. The aim is to offer base line data necessary to assess metal mobility and bioavailability. The distribution of heavy metals such as Cu, Ni, Cd, Cr, Zn and Fe was determined using multi- step sequential extraction. The results obtained indicate that the permeability is 6.24 x 10-3 cm/sec; porosity is 35%; and specific gravity is 3.58. The tailings is well graded and is sand gravel. Nickel and Zinc was found to be considerably high in exchangeable and bound to carbonates fraction which are mobile region and is bound to Fe – Mn oxides which is slightly mobile region but the higher concentration of Ni found in residual fraction. The implication of this result is that Nickel and Zinc partially enter into the food chain. Chromium and Cadmium concentration result indicated that these metals can easily enter into the food chain because of their presence in the mobile region and their higher mobility percentage.

A number of soils were examined from areas of a mine waste contaminated with heavy metals. Soils from areas vegetated with Agrostis gigantea Roth, which did not possess copper tolerance were compared with adjacent barren areas. Soils from sites which supported non-tolerant grasses had higher pHs and were lower in water-extractable metals than soils from non-vegetated areas. The soils did not differ with respect to any other factor examined. The non-vegetated soils were shown to be more toxic to the growth of Avena sativa than vegetated soils. The establishment and survival of grasses not having the selective advantage of copper tolerance were found to be restricted to the less toxic regions of the study site.
