VEGA 1/0146/18; (2018-2021); scientific co-worker (chief researcher was Assoc. Prof. Martin Urík, PhD.); Effects of microbial extracellular metabolites and bio-transformation processes on mobility of Mn, Fe and Si, and other environmentally significant micro-nutrients; This project studies the mutual interaction of microorganisms or their extracellular metabolites and the surfaces of solid amorphous or crystalline inorganic phases, which affect the mobility and bioavailability of various elements.; ABSTRACT: Although Fe, Mn and Si are important micronutrients from the point of view of agrobiology and no less important elements from the viewpoint of geochemistry, the influence of filamentous fungi on their mobility in the environment is omitted in current literature. However, chelating and redox properties of fungal extracellular metabolites, rapid metabolism and high tolerance to chemical stressors, make this heterotrophic group ideal candidate for efficient mobilization of nutrients in soils. This unique property is, however, two-sided and can also mobilize hazardous substances bound in natural geochemical barriers, the dominant component of which is iron and manganese oxides and hydroxides. Therefore, this project is primarily assessing the impact of this significant heterotrophic microbial group, especially their extracellular products, on the stability and transformation of solid phases with high Fe, Mn and Si content and related changes in mobility and bioavailability of these nutrients in the environment. 

VEGA 8 1/0836/15; (2015-2018); scientific co-worker (chief researcher was Assoc. Prof. Peter Matúš, PhD.); Interdisciplinary research on speciation, biosorption, bioavailability, bioaccumulation, biotransformation and toxicity of aluminium and other chemical elements entering the food chain within the soil ecosystems of Slovak Republic The spectrochemical methods as well as techniques of speciation analysis and fractionation will be applied to the model experiments and real samples to research the speciation, biosorption, bioavailability, bioaccumulation, biotransformation and toxicity of aluminum and other elements in selected components of soil ecosystems (soil, water, biota) of SR. The most suitable methods for the separation and determination of chemical species and fractions of monitored elements will be designed after critical evaluation and optimization of existing non-chromatographic techniques. The project aim is to contribute to the quality control and safety of plant and animal agrofood and extend current knowledges on the prevention of its contamination by toxic elements and production of functional foods fortified by essential elements, since the total concentrations of elements (compared with the concentrations of their species and fractions) are not always sufficiently represent their physiological and clinical effects.

VEGA 8 1/0164/17; (2017-2020); scientific co-worker (chief researcher was RNDr. Marek Bujdoš, PhD.); Effect of iron oxohydroxides on the movement of biogenic and hazardous elements in soils and their potential for entry into the food chain: ABSTRACT The aim of the project is to study the interaction of iron oxides and oxyhydroxides and biogenic elements (some macro - and microelements) and selected hazardous elements (toxic elements with biogenic and anthropogenic origin), which form oxyanions. Fe oxyhydroxides are a natural component of soils and sediments and their properties, especially the ability of sorption at the surface, makes significant impact on the cycles of elements in soils and waters. Parameters of bonding of element species to Fe oxyhydroxides will be studied, the conditions will be determined under which sorption occurs and in which the elements are re-mobilized and can be bioavailable. The transfer of elements into plants, which occur in the natural environment and agricultural soils and can introduce elements into the food chain will be studied. The results will be used to predict the movement of elements in the environment depending on the conditions and as a basis for remediation processes in which Fe oxyhydroxides are used.

VEGA 1/0331/23; (2023-2026); principal investigator; Innovative approaches to the methodological study of the properties of inorganic nanoparticles during their biosynthesis and transformation and other aspects of behaviour in the soil-plant model system using LA-ICP-MS, Mössbauer spectroscopy and other spectrometric methods: ABSTRACT Detection, quantification and transformation of nanoparticles in plant tissues and soil is a current issue with considerable attention from environmental and analytical chemists and geochemists. The project aims to create synthetic inorganic nanoparticles made of various elements (Au, Ag, Fe, Ti and Zn) by biosynthesis using plant and fungus extracts and to design, develop and validate innovative methodologies for LA-ICP-MS and Mössbauer spectroscopy to detect and quantify these nanoparticles in a soil-plant system. These methods, along with other spectrometric and electron microscopy methods, will help with the study of the factors affecting the transformation, distribution, and bioaccumulation of these inorganic nanoparticles and their potential to affect the translocation of potentially toxic elements (As, Cd, and others) to various plant parts.

VEGA 1/0175/22; (2022-2025); scientific co-worker (principal investigator is doc. RNDr. Martin Urík, PhD.); The influence of the interaction of humic substances and microorganisms on the mobility and bioavailability of iron: ABSTRACT Iron is an important micronutrient, and its amorphous and mineral phases are no less important components of the environment. However, reports on influence of microscopic filamentous fungi on its mobility and speciation is scarce. Nevertheless, both chelating and redox properties of the extracellular metabolites of this soil microbial group are factors that regulate its release from solid phases and its subsequent transfer into plants. Soil organic matter is another major factor influencing iron distribution. In particular, its component, humic substances, participates in its reductive dissolution and sorption. Thus, microbially induced alteration of humic substances also changes the geochemical behavior of iron. Therefore, the aim of this project is to analyze speciation and distribution of iron in a complex matrices of soils, and microbial and plant biomass, which would provide insight into the mechanisms and consequences of the interaction of biotransformed solid iron phases and humic substances.

Nanoparticles (NPs) are applied to plant leaves as foliar fertilizers and are absorbed into plant tissues and can affect plant growth and photosynthetic efficiency. The aim of this research is to develop a reliable and simple method to generate stable leaf cross-sections for research by using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to measure leaf cross-sections in lentil (Lens culinaris) plants. The first objective of the research proposal is to develop an innovative exploratory method adapted for the basic quantification of the mass transfer of elements from which NPs are formed in plant leaf cross-sections. We then propose the development of a simple, time- and material-efficient leaf cross-section method for the precise measurement of elements in leaf cross-sections with high resolution. This methodology can help to track the distribution of NPs in plant leaf tissues and elucidate how they interact with plants. The project aims to contribute to the scientific community's understanding of how NPs interact with plants, with potential implications for sustainable agriculture and environmental management.
