Monitoring of stream waters and sediments before and after settlement in city of Zagreb

In many environmental applications, decomposing the mixture of substances in the water into its various chemical ingredients for subsequent analysis is a very complicated task. The most productive approach to diagnosis is to treat the object as an integral spectroscopic sample, characterized by certain specific spectral fluorescent signatures (SFS). The SFS are recorded as a matrix of fluorescent intensity, in coordinates of excitation and emission spectra, of organic compounds in water, providing a three-dimensional spectrum. The objective of this study was to evaluate and compare the amount of the pollution of streams in city of Zagreb before and after settelment analaysing TOC and fluorecent signatures (SFS) by Fluo-Imager. With the Fluo-Imager Spectral windows SFS are defined by fluorescent characteristics of basic groups of organic substances in the water sample. The results showed that mineral oils in stream waters before settlement are below 5 mg/l and in range from 5 – 356.7 mg/l after settlement. Analysing of TOC in waters showed that they have less total organic carbon before settlement, from 0.72 mg/l to 1.57 mg/l and more TOC (from 1.03 to 2.35 mg/l) after settlement. In sediments total organic carbon were in range from 0.28 to 0.68 % dry mass before settlements, and from 0.60 to 8.60% dry mass after settlement. The results indicate that these applied methods are very quick and could be very usefull in biomonitoring of pollution in streams and thereby in monitoring of population influence on environment.
