The proposed project focusing on the use of fluorescent properties during tracer tests reflects the absecne of tracer substances not modifying the hydrochemical properties of the environment and not being radioactive. A positive result of the proposed research will enable more accurate evalutation of absorption properties of the rock environment in case of leakage of hazardous substances than it is for chemical tracers. Fluorescence salts offer the possibility of continuous monitoring of fluorescence changes without endangering the environment and without negative effects on hydrochemistry. Research will proceed according the fillowith scheme: bibliography-laboratory research-field tests-mathematical modeling. The project proposer has already acquired a patent and design rights in the frame of previous research project concerning the developed facility and technology enabling continuous monitoring and evaluation of fluorescence changes in liquids. The investigation of interaction between fluorescent salts and migratory pproperties of the rock environment will focus on rock with fracture permeability. Further selection of fluorescence salts accomplishing the objectives of the project will be based on the detailed bibliographic study. Particular fluorescent salts will be investigated in laboratory scale on selected rocs. Most promising fluorescence solutions will be consequently used for migration tests in specified rock environment with fracture permeability. The research polygon will be equipped with small-diameter boreholes interconnected by fracture network with two network section - with and without sorption properties. The results of both, laboratory and field tests, will be validated by mathematical models.
