Abstract

This paper aims at monitoring the water quality and the pollution degree on a relevant sector from the Lower Danube using the levels of nutrients, minerals, organic matters and the oxygen conditions as the specific indicators. For this study, water samples were taken from 5 different sampling stations: Priza Dunarii, the confluence of the Danube with the Siret and the Prut, Dunare-Liberatatea, and Cotul Pisicii. In order to determine the pollution degree of the Danube water in the adjacent area of Galati city, nine chemical parameters were analysed: total nitrogen, nitrates, nitrates, ammonia, total phosphorus, chlorides, sulphate ions, total organic carbon (TOC) and chemical oxygen demand (COD). The results obtained were used to assess and classify the quality of the Lower Danube water into quality classes according to the Water Framework Directive transposed in Order 161/2006.
