The humic substances (HS) are always present in the natural waters to a greater or lesser extent. Their property to fluorescent while being excited optically can be applied to use humic substances as a water ecosystem natural indicator. To realize the possibility of using HS as an natural indicator it is necessary to ascertain the correlation between the fluorescence characteristics of HS, their fluorophore structure and the genesis of HS with the influence of the parameters of the environment. It is also important to analyze these rules in the water surface micro-layer which is very important in the mass exchange between the hydrosphere and atmosphere (and in the pollution transfer also). The results of the determination of the molecular photophysical parameters of the HS fluorophores of different genesis are presented in the paper. The non-linear and kinetical fluorimetry methods with variation and artificial neural net algorithms were applied. During the research were solved the inverse problems for which the kinetic fluorescence curves were taken as an initial data. The curves were obtained through the HS excitation with the third harmonic of Yag-Nd Laser. The differences in the meanings of these parameters are discovered. The precise analysis of the shape of HS fluorescence band is accomplished. The results of this analysis are used to determine the structure of the water masses using the fluorescence characteristics of HS. The differences of the HS fluorescence characteristics in the water surface micro-layer and in the water volume is discovered. The ability of determining the structure of water micro-layer by laser probe is shown. The significant investigation result is the possibility of distinguishing the small fluorescenting anthropogenic admixture from the intense HS fluorescence background.
