AB  - The main goal of this work is focused on water quality classification of the Sava River (Serbia) and the evaluation of temporal/spatial variations of pollution data and the interpretation of a large complex water quality data set obtained by the monitoring of significant quality parameters measured during the several years of monitoring. Selected chemometrics techniques, such as principal component analysis (PCA), factor analysis (FA), cluster analysis (CA) and discriminant analysis (DA), were applied to the dataset obtained by monitoring more than twenty physico-chemical quality parameters for water samples. Multivariate analysis of very complex matrix demonstrated the power of chemometrics in identification of factors as groups of correlated variables with the highest percentage of explanatory variance. Natural clusters of analyzed variables with a similar pollution character were identified for the investigated period of time. Chemometrics tools appeared as very efficient for river water classification and rapid assessment of water quality necessary for management of water resources.
AB  - U uzorcima vode iz životne sredine, kao što su površinske, podzemne i otpadne vode nalazi se veliki broj elemenata i jedinjenja, koji redovno moraju biti praćeni, kako bi blagovremeno bili uklonjeni u cilju prečišćavanja vode i održavanja kvaliteta vode u propisanim granicama. Zbog toga je veoma važno na vreme utvrditi pravilnost i zakonomernost u pogledu promene raspodele sadržaja zagađujućih materija i predvideti pravac njihovog daljeg kretanja. U ovom radu pažnja je posvećena analizi sadržaja najvažnijih elemenata koji su bitni za kvalitet vode (teški metali, pojedini katjoni i anjoni, organska jedinjenja), a takođe su mereni i praćeni neki fizičko-hemijski parametri (temperatura, pH, boja, mutnoća, provodljivost). U ispitivanjima je analizirana površinska voda reke Save. Analiza i statistička obrada svih rezultata merenja urađena je primenom multivarijantnih statističkih metoda. Izabrane hemometrijske tehnike, kao što su analiza glavnih komponenata (PCA), faktorska analiza (FA), klasterska analiza (CA) i diskriminaciona analiza (DA) primenjene su na primeru sveobuhvatne analize i procene kvaliteta rečne vode, praćenjem preko 15 fizičko-hemijskih parametara bitnih za kvalitet vode, uzorkovanih u višegodišnjem periodu i u različitim sezonama. Na ovaj način izvršena je karakterizacija i klasifikacija kvaliteta savske vode i evaluacija podataka o zagađujućim materijama.

AB  - Belgrade's water supply relies mainly on the River Sava and groundwater supply wells, which are located in the vicinity of the river and Ada Ciganlija. In this paper, the contents of aluminum, boron, chromium, manganese, cobalt, nickel, copper, zinc, arsenic, cadmium, barium and lead were analyzed in raw water as well as drinking water distributed by the Water Supply and Sewage of Belgrade. A total of 14 samples were examined from all water treatment plants that are part of the distribution system. The measurements were conducted using the inductively coupled plasma-mass spectrometry (ICP-MS) technique. The aim of this research was to examine the effectiveness of the drinking water preparation process in the plants belonging to the Water Supply and Sewage of Belgrade. The content of certain elements varies considerably in raw water (river and groundwater): the concentration of boron in river water is two to three times lower than the concentration in groundwater; the concentration of arsenic in river water is ten to twenty five times lower than the concentration in groundwater; the concentration of aluminum in all groundwater samples was below the detection limit of the instrument (0.50 μg/dm3), whilst in the river water the content of aluminum was about 50 μg/dm3 and the concentration of manganese in the river water was up to 10 times lower than the concentrations in groundwater. In all drinking water samples the concentration of the elements were bellow the maximum allowed levels according to the Serbian regulations. Correlation coefficients determined for boron, manganese, cobalt, nickel, copper, zinc, arsenic, barium and lead, which were analyzed in raw waters, show that four groups of elements can be distinguished. Boron, manganese, arsenic and barium are related to each other and probably have a common natural origin; copper and lead probably have a common anthropogenic origin; correlation of nickel and cobalt was observed, while zinc was not in correlation with any other element.
AB  - U ovom radu ispitivan je sadržaj aluminijuma, bora, hroma, mangana, kobalta, nikla, bakra, cinka, arsena, kadmijuma, barijuma i olova u sirovoj vodi i vodi za piće koju koristi, odnosno isporučuje potrošačima Javno komunalno preduzeće Beogradski vodovod i kanalizacija. Ispitano je ukupno 14 uzoraka sa svih pogona za pripremu vode koja su u sastavu Beogradskog vodovoda i kanalizacije. Analiza uzoraka je rađena primenom indukovano spregnute plazme sa masenom spektrometrijom. Cilj istraživanja je bio da se ispita efikasnost procesa za pripremu vode za piće koji se primenjuju u pogonima Beogradskog vodovoda i kanalizacije. Iako su koncentracije pojedinih elemenata u sirovoj vodi bile u širokom opsegu vrednosti i znatno se razlikovale u podzemnim i rečnim vodama, u uzorcima vode za piće koncentracije svih ispitivanih elemenata bile su niže od maksimalno dozvoljenih koncentracija propisanih zakonskom regulativom Republike Srbije.
