Storage of ash and slag waste causes a number of environmental problems, including the transformation of natural geochemical cycles and the change of the natural radioactive background due to the increased concentration of heavy metals and radioactive isotopes in coal combustion products. Plants can provide an effective approach for the analysis and monitoring of heavy metals contamination. Additionally, vegetation plays a significant role in the restoration and remediation of heavy metal-contaminated soils. The application of plants in phytoremediation is a green and sustainable solution for decontaminating polluted sites. Moreover, the key role in the restoration of contaminated sites belongs to native species. Within the presented research, the abilities of native dominant species to accumulate and tolerate heavy metals in conditions of ash and slag dumps were investigated on a limited number of samples. Primary analysis of the bioaccumulation of heavy metals through the bioaccumulation coefficient showed that zinc has the highest accumulation capacity in the studied species. The ability to bioaccumulate the analyzed heavy metals decreases in the following order: Zn > Fe > Cu > Mn > Cd > Ni > Pb. Indexing the biogeochemical activity of the tested species showed higher levels of biochemical activity for Anthemis arvensis L. than for Achillea millefolium L., however, these data need to be confirmed by statistical analysis. Determination of the translocation index of elements reflected the high mobility of zinc and cadmium with a high rate of transferring to above-ground biomass, but the potential for accumulation requires scaling up the experiment with the involvement of a larger number of samples and performing statistical data processing. Due to their ability to accumulate heavy metals in roots, plant species could be used for phytostabilization. Establishing methods of biomonitoring and the development of green reclamation technologies with native species application need further research with both selected species and other local species. The presented research showed primary results of bioindication and references for phytoremediation of heavy metal contamination of the ash and slag dumps, which is relevant for other similar environmental conditions.

This article dealing with the problematic contamination surface water in dumps complex and there were monitoring basic physical and chemical parameters, toxic and strategic metals. There were analysed inorganic ions NH4, Cl, SO4, NO3, NO2 by standard laboratory analysis, and the elements Pb, Cd, Cr, Cu, Ni were measured by method ICP MS, and elements Zn, Fe, Mn, Na by method AAS. The case study of the contamination in the Burňa watercourse basin, in industrial landscape of the Ostrava city is unique in solving the problem of ecological burdens of the Ostrava city. One year of monitoring case study showed a significant load on the watercourse with the expected contamination especially by toxic metals. The surface water Burňa watercourse was affected by a dumps complex and their chemistry. The source of the contamination is the impact of former mining, in this post-mining landscape.
