In the context of the continuing decline of the species belonging to the order Acipenseriformes on a global level, the anadromous sturgeon species sturgeon species in the Lower Danube have been affected by a significant reduction in historical migration routes and fragmentation of breeding habitats. This paper presents the stages of the methodology...

The presence of emerging pharmaceutical pollutants in the aquatic environment is generally related to anthropogenic activities such as domestic, industrial and hospital wastewater discharges and landfills. Special attention should be paid to the contamination of surface waters, as they are partly used for drinking water supply, since they directly...

Anadromous sturgeon populations in the Lower Danube are in severe decline, and this is due to a combination of anthropogenic and natural factors that have a major impact on the life cycle of the species. Stationary swimming parameters, namely water temperature and depth, represent the starting point for developing the best procedures to identify br...

Abstract The stability of air masses in the atmosphere influences not only the dispersion but even the accumulation of pollutants in certain areas. The most common methods for determining the stability in the atmosphere are the Richardson number, the Monin-Obukhov length and the Pasquill-Gifford method. For this study, the Monin-Obukhov length met...

In big cities, certain meteorological phenomena can affect air quality even in cases where the main sources of pollution such as traffic have low intensity. The air pollution varies greatly, depending on the emission source and the type of pollutant. In addition, the dispersion of air pollutants is influenced by weather conditions, as well as other...

In the Lower Danube, sturgeon populations have declined dramatically in recent decades. Although efforts have been made at the legislative level since 2006, by forbidden commercial fishing, an assessment of stocks and conservation status of sturgeon species has not yet been made. In this context, it is necessary to estimate the age and growth rate...

The Black Sea sturgeons are anadromous fish species, which migrate upstream on the Danube River for breeding. The distance traveled in the migration process varies depending on each species, from tens to hundreds of kilometers . After breeding, the anadromous sturgeons return to the Black Sea and go back to the Danube after a time that varies depen...

The sturgeon species are a flagship species of the Danube River Basin that acts like an indicator of ecological health. They are protected by several international conventions (CITES, Habitats Directive, the Bern Convention and the Bonn Convention) and are assessed as endangered by the IUCN. Starting from 2011 the National Institute for Research an...

To acquire precise data on the hydrodynamic parameters is of major importance for the characterization of a watercourse. In this regard, specialized techniques have been developed and used in order to measure, process, analyze and forecast the data which define the watercourse, such as: riverbed bathymetry, flow, water level and water current veloc...

Sturgeon species are listed as some of the oldest species, adapting continuously to the various natural changes in their living environment. On the territory of Romania there were 6 sturgeons species of the genus Acipenser and Huso, but due to anthropogenic influences, it seems that two of the six sturgeon species are extinct, namely Acipenser nudi...

Danube River is of particular importance for countries whose territories it crosses, both economically but in its impressive biodiversity too. Thus, it is important to know the distribution of pollutants in certain areas of interest, in order to mitigate their expansion and to decontaminate the pollution prone zones. In this study was assessed an a...
