Abstract:
During the last five decades, fluorescence spectroscopy has been intensely applied to the study of aquatic environment due to the method high sensitivity and ability to analyze rapidly and noninvasively the water samples. These studies are focused on the analysis of a complex mixture of compounds that form the fluorescent fraction of the dissolved organic matter.
Dissolved organic matter is present in all aquatic systems and has a great influence on the biological, chemical and physical state of the water body. The organic matter can be formed in situ through microbial degradation or transported into the water system by anthropogenic and geologic activities. Dissolved organic fluorescent compounds that determine the water quality are humic substances derived from plant degradation and aminoacids (tryptophan and tyrosine) from proteins. This work reviews the state of art in fluorescence spectroscopy applied to the study of aquatic organic matter.
