HUMAN DAILY ACTIVITIES REFLECTED BY THE ECOLOGICAL STATE OF NATURAL WATER RESOURCES

The study aimed at a new approach for assessment of lake water quality, correlating physico-chemical analyses and spectroscopic data with pollution sources. Water quality of lakes from a major urban area was analyzed and correlated with specific degradation sources along each lake. The results showed that water quality is impacted by the antropic activities, which leave a specific mark on these systems. Strong microbial activity, resulting from the wastewater inputs in lakes was reflected by the high nutrients level and the high fluorescence intensity of protein-like components. The presence of birds and restaurants in the vicinity of the lakes can also induce bad water quality, reflected by a peak in the protein-like spectral domain, appearing at different wavelength than that associated with the wastewaters input.
