dc.description.abstract This paper analyzes the pollution of the Prut River with ammonium nitrogen (NH₄⁺) during the period 2019–2021, focusing on exceedances of the maximum allowable concentration (MAC) of 0.2 mg/L. The analyzed data comes from measurements taken in various localities along the river. The results indicate constant pollution with significant exceedances of the MAC, the highest measured concentration being 3.85 mg/L. Descriptive analysis reveals an asymmetric distribution, with extreme values raising the average to 0.8456 mg/L. The 2019–2021 period was chosen because this interval recorded significant MAC exceedances. Urban localities, such as Leova and Lipcani, show the highest concentrations, and are correlated with intense human activities. The conclusions emphasize the need for urgent action to reduce pollution and protect aquatic ecosystems and public health. en_US
dc.description.abstract Această lucrare analizează poluarea râului Prut cu azot provenit din amoniu (NH₄⁺) în perioada 2019–2021, punând accent pe depășirile concentrației maxime admisibile (CMA) de 0,2 mg/L. Datele analizate provin din măsurători efectuate în diverse localități de-a lungul râului. Rezultatele arată o poluare constantă, cu depășiri semnificative ale CMA, cea mai mare concentrație măsurată fiind de 3,85 mg/L. Analiza descriptivă evidențiază o distribuție asimetrică, cu valori extreme care ridică media la 0,8456 mg/L. Perioada 2019–2021 a fost selectată din considerentul că în acest interval s-au înregistrat depășiri semnificative ale CMA. Localitățile urbane, precum Leova și Lipcani, prezintă cele mai mari concentrații, fiind corelate cu activitățile umane intense. Concluziile subliniază necesitatea unor măsuri urgente pentru reducerea poluării și protejarea ecosistemelor acvatice și a sănătății publice. en_US
