Dinamica compușilor azotului mineral în apele râului Prut

In this article the results on the content of mineral nitrogen compounds (ammonium ions, nitrites and nitrates) during 2020 year in the Prut River Braniște – Giurgiulesti sector are presented. In the study is examinated the seasonal dynamics of these parameters in the winter – spring – summer – autumn period. The range of ammonium ions in the waters of the Prut River varies from 0.002 to 0.26 mgN /L, of nitrite – from 0.002 to 0.02 mgN /L and of nitrates – from 0.002 to 0.73 mgN /L, the maximums being lower than in 2009-2010, and much lower than in the 80s-90s of the last century.
