Bucharest is one of largest cities in Romania and disposes of natural and artificial lakes, which are utilized for different economical and leisure purposes. Water samples collected from lakes within the urbanized area were characterized by oxygen indicators (dissolved oxygen, chemical oxygen demand), nutrients related indicators (ammonia, nitrates) and spectroscopic response (fluorescence spectroscopy). The standard parameters were correlated with the fluorescence measurements and with pollution sources situated in the proximity of lakes. Degradation of water quality was noted for lakes which have individual residential areas in the proximity, in comparison with lakes surrounded by green spaces, collective residential or industrial areas, and even open fields.
