The analysis of the samples also showed high concentrations of nitrogen and phosphorus in sections of the Danube near Budapest and Belgrade, suggesting also a need for more studies and measures to improve the quality of the water.
Analiza uzoraka takođe je pokazala da postoji visoka koncentracija azota i fosfora u delovima Dunava u blizini Bukurešta i Beograda, što takođe ukazuje na neophodnost novih studija i merenja kako bi se unapredio kvalitet vode.
