This scientific achievement is the result of research work carried out on the project in collaboration with national and foreign collaborators. The work describes the development of a biological sensor (biosensor), which is based on live bacterial cells and is used for the detection of biologically available mercury. Based on the research performed in the project, we concluded how different matrices in the environment (i.e. soil, sediment, fresh and salt water, etc.) can affect the availability of biologically available mercury. We also concluded that the use of ecologically relevant microorganisms is very important when detecting bioavailable mercury in the environment. The use of the automated detection robot allowed us to culture these strains and perform the analysis at the same time. The system represents a platform for the development of future biosensing systems that will incorporate microorganisms from the environment that will be under examination. At the same time the system can be used as backbone for the development of new biosensors that can detect other forms of pollutants in the environment.

The paper describes the validation of methods for the determination of elemental and bi-valent mercury in aqueous solutions. The method is based on a FIA principle where volatile elemental Hg (0) is separated in the gas-liquid separator and detected by atomic absorption spectrometry. The validated method was used in measuring Hg (0) in surface waters (concentrations in the range from 0.01 to 0.5 ng / L) and a solution of a desulphurisation unit of the termo power plant (concentrations ranging from a few ng to 100 ng / L).

A method based ID ICP-MS was developed for measuring Hg (0) in the air, which allows traceability of measurements to SI units. It is a completely new approach which confirmed deviations from conventional Dumarey equations in the working temperature range for about 6-8%.
