Spatio-Temporal Characterization of Nutrient Pollution
in Lower Danube Area


Abstract:

Eutrophication of large river systems, as a result of the increasing content of nutrients, is one of the major issues in water quality facing the authorities in the European countries. It is closely related to the environment, incurring profound effects on biodiversity of aquatic ecosystems, yet not fully understood so far. The present study is based on the characterization of spatio-temporal trend of nutrient pollution of the Danube River during one year, namely, from September 2012 to September 2013 in Calarasi-Braila sector. The studied area was chosen on the basis of some construction works which took place for improving the navigation conditions, which might have a potential negative impact on water quality and on biodiversity. Water quality assessment was carried on in 10 monitoring stations, which revealed significant pressure upstream pollution. The results disclosed the level of eutrophication and the relationship between the parameters analyzed and the influence of the land usage. Keywords: eutrophication, nutrients, surface water, Danube River
