Assessment of Anthropogenic Pollution in Urbanized Ergene River by Fluorescence and Absorbance Spectroscopy

According to fluorescence spectrometer measurements of samples taken from Ergene River which is contaminated from both natural and anthropogenic sources, the characterization of natural organic matter in river and identification of the anthropogenic pollution in the river can be detected in a range of excitation and emission matrix. The samples are taken from eight different points begins from the origin of the river to the other regions close to domestic and agricultural activities. As a result of EEM-PARAFAC modelling, two protein like components are detected which indicate anthropogenic activities. The fluorescence results are correlated with the values of specific ultraviolet absorbance at 254 nm (SUVA254) and spectral slope parameters (S275-295, S350-400 and SR) of the river water samples. In future studies, the fluorescence spectroscopy will be applied to the river water samples before and after photodegradation spiked with emerging contaminants (ECs) such as ciprofloxacin, clothianidin, imazamox, imidacloprid, tetracycline, triclosan.
