The area of the former mining plant Plumbum, located in the city of Adrianopolis (Paraná) received mining wastes enriched with potentially toxic metals. These mining wastes were disposed directly on the ground without any previous treatment, being exposed to weathering processes until the year 2007, when such materials received thin soil coverage. Even with the coverage, mining waste in d…
Anthropogenic activities, such as mining and the use of fertilizers in agricultural areas, are identified as the main responsible for the contamination of the environment by potentially toxic metals. Potentially toxic metal, especially lead (Pb), cadmium (Cd), and zinc (Zn), offer a risk to ecosystems and human health, since, while contaminating the soil, they can infiltrate and contamina…
Potentially toxic metals (PTM) include both elements that are considered essential and non-essential. They occur naturally in the environment, most of the time in low concentrations, depending on the geological material. It is noteworthy that anthropic activities interfere with the biogeochemical cycle of PTMs, which can cause them to reach levels that are toxic to the ecosystem, mainly d…
In Brazil and worldwide, many areas have been contaminated by inadequate disposal of mining waste containing potentially toxic metals. Among these metals, there is zinc (Zn), which is an essential element with great biological importance for plants, animals, and humans, but which becomes toxic in high concentrations. Thus, it is necessary to develop techniques (if possible at low cost and…
Mining activities changes the natural geochemical cycle of potentially toxic metals, often culminating in environmental liabilities associated with the intense contamination by these metals. From this perspective, an alternative is the disposal of mining waste, which still contains considerable concentrations of the interest metals in an encapsulated form through the sealant and cover bar…

Mining can drastically modify the potentially toxic metals natural geochemical cycle, leading to intense contamination by such elements. Therefore, an alternative is the use of so-called reactive materials, which stand out for their recognized metallic contaminants capacity retention. They can be used both in the construction of sealant and roofing barriers, as well as in amendments in so…
Adsorption evaluation plays a fundamental role in the study of potentially toxic metals retention by geologic materials. The study of adsorption of Pb, Zn and Cd by natural residual soils and by mixtures of these soils with peat and organic compost is being carried out in the Master Project developed in Brazil. However, only the characterization of the adsorption behaviour and the determi…
This project will be developed in partnership with the University of Aveiro. Thus the adsorption tests shall be carried out with Pb and Zn by unconsolidated materials (transported soils) provided for in the project of Scientific Initiation. The laboratory where the student will perform the stage is focused for geological and geochemical analyses, with the necessary equipment to conduct th…
