Flotation tailings, formed mainly in copper mining, are the largest percentage of waste generated during the extraction of mineral resources. Polish copper mining deposits 100% of tailings in landfills. Flotation tailings, although there are many concepts of management, is unused. This waste contains a considerable amount of toxic metals that can pollute the natural environment near the reservoir of flotation tailings and accumulate in plant tissues. The aim of our research was to evaluate the heavy metals concentrations in soils and their bioaccumulation in plant and mushroom tissues from a landfill.
