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...

This research is a necessity given the importance of conserving and protecting aquatic ecosystems, as well as declining species, especially sturgeon species. Given that these species are considered vulnerable and critically endangered according to IUCN Red List rules and because there is currently insufficient data to prove their possible breeding...
The aim of this research was to evaluate the results obtained by ultrasonic tagging of sturgeon species and to collect field data for the period 2019-2021. Thus, an analysis was made of the information collected from the beginning of the period and also will be presented the migration capacity of sturgeons in the area of hydrotechnical arrangements...
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...
Pharmaceuticals are a major group of emerging pollutants frequently identified in surface waters. The occurrence of pharmaceuticals as environmental pollutants is a problem involving multiple aspects and continue to cause new and serious challenges to ecosystems and human health. For example, antibiotics exert a selective pressure on bacterial comm...
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...
Located in the Danube Delta Biosphere Reserve, the Chilia branch serves as country boundary between Romania and Ukraine. The former state started in 2004 a project intended to increase the navigability capacity of Bystroe Channel, the environmental impact of the works carried out being discordantly considered by the Romanian and Ukrainian authoriti...
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...

Intensiv sturgeon monitoring on the Danube in Romania
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...
The importance of the sturgeon species conservation has conducted to the development of numerous research projects to complement and improve the current knowledge of the behavior of these species. The sturgeon anadromous migratory species are sensitive to hydromorphological changes, which is of particular importance for the monitoring of their beha...
The monitoring carried out by the INCDPM team for sturgeon species during the period 2011-2016 showed that upstream migrations of the beluga specimens it is realizing in 98% on the Borcea branch and only 2% on the Old Danube (km 248-345) and in proportion of 96% on Borcea and 4% on the Old Danube in the case of the stellate sturgeon species. Given...
Sturgeon are cartilaginous bony fish species appeared more than 200 million years ago. Four of this species are still found today in the Black Sea and the Danube River. Historical data and archaeological discoveries show that fishing for this species dates back more than 5000 years along the Danube. However, a multitude of anthropogenic factors has...

Air quality modelling is an essential tool for most air pollution studies. The air quality models are the means whereby pollutant emissions can be related to atmospheric pollutant concentrations. The uncertainties in assessment of air quality are related to both the quality of measured values of pollutant concentrations in local network and the inp...
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...
