<p>Eksperimentalnim istraživanjem u okviru doktorske teze utvrđen je trend promene fizičko-hemijskih parametara: mutnoća, temperatura, provodljivost i pH vode, koncentracija katjona Cd2+, As3+, Hg2+ i Pb2+, ukupnog azota, fosfora i sulfatnog ajona u vodi i sedimentu, na lokalitetu Zapadne Srbije, slivno područje akumulacije Vrutci u 2003/2014. Rezultati istraživačkih aktivnosti predstavljali su osnovu za razvoj regresionog modela kojim se može predvideti koncentracija katjona teških metala u jezerskoj vodi. Primenom klaster analize, dendograma i PCA analize dobijena su tri faktora na osnovu kojih se posmatra uticaj ključnih fizičko-hemijskih parametara na kvalitet vode zatvorenog vodnog tela akumulacije pri čemu su dobijene visoko korespodentne funkcionalne zavisnosti sa realnim podacima u jezeru. Ovakva istraživanja su po prvi put sprovedena za selektovani lokalitet u Srbiji.</p> / <p>Experimental studies in the doctoral thesis established the trend of changes in the physico-chemical parameters: turbidity, temperature, conductivity and pH of the water, the concentration of cations Cd, As, Hg and Pb, total nitrogen, phosphorus and sulphate anion in water and sediment at the site of Western Serbia, the catchment area of the reservoir Vrutci in 2003/2014. Results of research activities constituted the basis for the development of a regression model which can predict the concentration of heavy metal cations in lake water. Cluster analysis, dendograms and PCA (principal component analysis) were resulted by three factors, which could be possible to registre the impact of key physical and chemical parameters on the water quality of the closed lake reservoirs.The obtained results by multivariance analysis has showen the highly correspondent functional dependence with real data in a lake. Such research investigations were for the first time carried out in selected localities in Serbia.</p>
