Danube River is considered one of the most important European rivers and it flows for a total distance of 2,860 km. The river plays an important role in activities such as transport and commercial fishing, which makes it permanently subjected to anthropogenic pressures. Metals are the main pollutants in Danube River and most of the pollution sources in the basin are found in Romania. The aim of the study was to evaluate water quality of Danube River Lower Sector in terms of heavy metals concentration (Cd, Pb, Ni, Cu, Fe, Zn) and to evaluate the environmental risk assessment, by calculating the pollution index for each analysed metal. Water samples were collected from the lower sector of Danube River, at river kilometres 150 and 170. The main conclusion of this research is that Danube River water in the lower sector is classified as a class I in the national quality ranking of surface waters in case of Zn, Cu, Ni, Pb, Cd concentrations, except for Fe concentration that classified Danube River water as a class V in the ranking.
