2017-2019: (deputy principal investigator) project VEGA 1/10597/17 "Geochemical conditions of mercury occurrence and mobility in environmental components of environmental burdens"

The project focused on the study of the occurrence and migration of mercury in the soil-water-plant system in abandoned mine areas of mercury mining. The greatest attention was paid to the abandoned mine area of ​​Merník in Eastern Slovakia. Despite high total concentrations of mercury (Hg) in mine wastes and soils, its mobilization into water and plant availability is minimal as Hg in these solid environmental matrices still occurs in the form of sparingly soluble and weathering-resistant minerals, as shown by solid-phase speciation results using micro-X-ray fluorescence (m-XRF) and synchrotron measurements (EXAFS).

2018-2022: (principal investigator) project APVV-17-0317 "Antimony - a critical element and a hazardous contaminant affecting biodiversity at sites with extractive waste".

The first analysis of critical raw materials was published in 2010. In this list, 14 critical raw materials were identified, among them antimony. Critical raw materials have a high economic importance for the European Union combined with the high risks associated with their offer. Currently, there is no primary source of antimony production in the EU. Overall, the EU is a net importer of antimony ores and concentrates. At the same time, antimony also representes a significant toxic contaminants occurring in Slovakia in all environmental compartments. In Slovakia, there were several significant deposits of antimony ores. They occurred primarily in three metallo-genetic areas: core mountains (Small Carpathians, Low Tatras), Spis - Gemer Ore Mountains, Central Slovakia and Eastern Slovakia Neovolcanites. The main objective of this project is to evaluate the potential of mining waste in abandoned deposits of Slovakia in terms of possible mining of antimony as critical raw materials for the European Union. Another important goal of the project is the definition of environmental and health risks associated with the use of mining waste as a raw material for obtaining Sb and the proposal of measures that should prevent negative impacts on the environment in the use of extractive waste. An important objective of the project is the microbiological study of mine wastes and the assessment of the potential of microbiological methods (biomining) in Sb eploitation. One of the project objectives is to determine the impact of contamination on the biodiversity at five abandoned Sb deposits. Within the molecular-genetic study, DNA information of higher organisms and microorganisms (method NGS) will be obtained. The total content of PTTEs will be determined in each studied abiotic, biotic and reference sample. Project will define PTTEs transfer from the contaminated environment into the selected groups of organisms (fungi, arthropods, fishes) as a potential sources of human intoxication.                                                                                                          

2019-2021: (deputy principal investigator) project VEGA 1/0678/19 "Occurrence, distribution and determination of chemical elements of platinum group and platinum cytostatics in solid matrices of the environment (soil, sediments and sludge) using modern methods of chemical analysis"

The project is focused on the study of occurrence, distribution and determination of elements of platinum (Pt) group and Pt cytostatics in solid matrices of the environment (urban land, river sediment and sludge). In the project, two main sources of the city pollution caused by Pt, due to the use of Pt compouds and automotive catalysts, will be solved. The obtained real data from the environment on the distribution of Pt in the solid phase-water system will be compared with the results from the study of the sorption of the investigated substances under laboratory conditions. Due to the low concentration levels of investigational substances in the environment, sensitive detection methods of atomic and molecular spectrometry with or without combination with liquid chromatography will be used.

2023-2026: (principal investigator) project VEGA 1/0246/23 "Spatial distribution, geochemical fractionation, oral bioaccessibility and bioaccumulation of hazardous trace metals/metalloids in soils and vegetables of urban community and private gardens in the city of Bratislava."

Gardens in the urban area have many functions, and one of them is the self-supply of the inhabitants with home-grown vegetables and fruits. On the other hand, the soil and the grown products can pose a health risk to people, because the urban area is typical of many emission sources of hazardous chemical elements. Primary objective of the presented project is the determination of the concentrations of trace metals/metalloids typical for the urban environment (e.g., arsenic (As), antimony (Sb), chromium (Cr), cadmium (Cd), manganese (Mn), copper (Cu), nickel (Ni), lead (Pb), mercury (Hg) and zinc (Zn)) in soils and vegetables of urban gardens in the city of Bratislava. Another objective of the project is the determination of oral bioaccessibility of these chemical elements using "in vitro" tests, which is a more appropriate indicator of potential health risk to humans. In addition, the project wants to find an answer to the question of whether soil properties, geochemical fractionation and soil mineralogy affect the distribution, in vitro bioaccessibility and bioaccumulation of hazardous metals/metalloids in soils and selected types of vegetables.

2022-2026: (principal investigator) APVV-21-0212 "Selected environmental burdens as a stress factor influencing biodiversity and health risks for exposed groups of the population."

Contaminated sites defined as environmental burdens pose a serious risk to human health and the biodiversity of organisms. Interdisciplinary study of environmental burdens aimed at defining the mobility of hazardous contaminants in environmental components carried out using modern field and laboratory methodologies in geochemistry, mineralogy combined with detailed knowledge of species biodiversity in such an anthropogenic environment is a key database for modeling potential risk scenarios for potential risk groups population. At the same time, such data are necessary for exact proposals of remediation measures aimed at eliminating the present risks resulting from the nature of hazardous contaminants of the sites. A comprehensive study of the biodiversity of the sites in question will provide a characterization of species communities in the sites, including their chemical composition as a potential entry of hazardous contaminants into the food chain, and species biodiversity of bacteria and fungi is the basis for bioremediation processes of contaminated matrices. The design of innovative remediation procedures for environmental loads currently represents a combination of stabilization of hazardous contaminants in the soil profile with bioremediation procedures and the use of various waste materials as contaminant sorbents. The long-term stability of the products of stabilization of risk elements in the soil profile under the natural action of the community of microorganisms and plants is critical for the effectiveness of the removal of contaminants from the environment. Detailed mineralogical and geochemical identification of contaminant immobilization products and especially definition of decomposition conditions of immobilization products with potential remobilization of risk elements in model environmental burdens will bring exact results for real remediation procedures in the field of environmental burdens.
