Cities have a significant contribution to the contamination of urban lakes by input with surface runoff, illegal wastewaters discharges, sewage discharges, which lead to increased eutrophication and reduce the ecological health status. Complex temporal monitoring is needed to understand the changes in water quality, including dissolved organic matter. This study presents the first temporal evaluation of dissolved organic matter from urban lakes, using fluorescence spectroscopy. Samples were collected from urban la...

Numerous past studies proved the potential of fluorescence spectroscopy to characterize aquatic organic matter and its link to function and chemical water quality. It was proposed as an optimum monitoring method due to its advantages, such as: rapid measurements, high sensitivity and selectivity, requires small quantities of sample with little or no sample preparation. Although fluorescence spectroscopy was used on different types of water systems, no complex study was undertaken to compare the fluorescence signal...
