Abstract. The water quality ranking in this study was conducted using the PROMETHEE/ GAIA method based on the monitoring data collected from seventeen measuring locations on the Danube in 2009. In terms of the investigation, ten water quality parameters (conductivity, pH, suspended matter, oxygen saturation, temperature, orthophosphates, total nitrogen oxides, biochemical oxygen demand (BOD-5), ammonium ion and E.coli) were used as ranking criteria. Locations were grouped into clusters according to the mutual dependence of the parameters. The results of the PROMETHEE/GAIA analysis indicate that the location with the best water quality is Dobra (L14), while the location with the worst water quality is Pančevo (L9). The direction of concluding suggests that Pančevo (L9) is the location of the potential environmental risks that require the implementation of adequate preventive measures in order to achieve and preserve better water quality in this part of the Danube.

RANGIRANJE LOKACIJA POTENCIJALNOG EKOLOŠKOG RIZIKA NA DUNAVU
Rangiranje kvaliteta vode u ovom radu izvršeno je korišćenjem PROMETHEE/GAIA metode, na osnovu rezultata monitoringa sedamnaest mernih lokacija na Dunavu u 2009. godini. Za potrebe istraživanja posmatrano je deset parametara kvaliteta vode (elektroprovodljivost, pH, suspendovane materije, zasićenost vode kiseonikom, temperatura, ortofosfati, ukupni oksidi azota, biološka potrošnja kiseonika (BPK-5), amonijum jon i E.coli) koji predstavljaju kriterijum rangiranja lokacija na Dunavu. Lokacije su grupisane u klastere prema međusobnoj zavisnosti parametara. Rezultati PROMETHEE/GAIA analize rangiranja pokazuju da je najbolji kvalitet vode na lokaciji Dobra (L14), dok je najlošiji kvalitet vode na lokaciji Pančevo (L9). Smer zaključivanja ukazuje da je Pančevo (L9) lokacija potencijalnog ekološkog rizika koja zahteva sprovođenje adekvatnih mera zaštite u cilju postizanja i očuvanja boljeg kvaliteta vode na ovom delu Dunava.
