Abstract

The ecological state of water environment is characterized by the contents of some organic substances in water. Due to the fluorescence properties of many organic compounds the laser fluorescence spectroscopy is widely used for remote sensing monitoring of natural water. In this paper the possibilities of laser spectroscopy were investigated to diagnose simultaneously the three most important ingredients of natural water: dissolved organic matter (humic substances), dissolved proteins, and petroleum hydrocarbons in dissolved-dispersed state. In our opinion the basic problem of fluorescence diagnostics is superposition of fluorescence bands from different organic substances. Getting information from sea water spectra is a very difficult task. For the solution of this problem the optimal wavelength range for fluorescence excitation of humic substances, petroleum hydrocarbons, and proteins was determined in this paper.
