The chemical agents are released a large amount into the environment (e.g. drugs, reagents and other harmful compounds). In spite of their high biological activity, their releases are not regulated properly. Their trace analyses require dedicated instrumentation (GC/MS, HPLC/MS-MS). Our primary goal is to establish new environmental determination methods for dangerous agents.

The source of our samples:  surface water, natural water, mineral water

The penetration of antropogenic contamination into soil and water is one of the most important environmental problems today. Some heavy metals pose serious health hazards through entry into the food chain by anthropogenic pathways. Certain natural materials of biological origin, including microorganisms possess metal-sequestering property and can be used to concentrate and accumulate heavy metal ions and in this way decrease their concentration.

The aim of the research is to explore the the defensive mechanisms of fungal cells: Saccharomyces cerevisieae, Candida tropicalis, and algal cells: Spirulina platensis and Chlorella vulgaris against metal ion contamination.

The concentration of fungal and algal cells may affect the amount of absorbed metal ion concentration. The basis of this phenomenon is the communication of cells depending on environmental metal ion concentration (quorum sensing). It is important to explore the transfer of information and the compounds which play a role in the defense mechanism against metal ions.

The microorganisms interact with each other using small molecules, they respond to environmental effects with different physiological processes. The Quorum sensing describes the phenomenon of microorganisms in which the individual cells detect with accumulation of the low molecular weight signal particles when the population has reached a minimum unit, or "a quorum", which induces a population response.

            The detection of QS molecules (mostly trace amounts of substances) is carried out from culture medium of yeast and algas, using qualitative and quantitative instrumental analytical techniques using GC / MS, HPLC / MS. The concentration of metal ions is determined by atomic absorption spectrometry and ICP-MS.
