Construction of the Danube Iron Gate Dam for hydroelectricity, 943km from the mouth of the Danube River, is changing sediment transport due to its retention in the Iron Gate Reservoir (IGR), ...potentially causing heavy metal enrichment, re-distribution within the solid phase, exchange or re-suspension on sediment–water interface. The concentrations of heavy metals (Cu, Zn, Pb and Cd) in water and sediment during a five-year period along the IGR were determined. The fluxes of heavy metals from river water to sediment due to sedimentation were determined, as well as their fluxes from the bottom sediment to the sediment–water interface due to sediment re-suspension at high flow rate, when fluvial erosion takes place and removes part of the previously deposited sediment from the river bed, in a yearly amount between 2 and 9%, depending on the hydraulic regime in the IGR.
•Surface sediment and water of Iron Gate Reservoir on heavy metals were analyzed.•The fluxes of heavy metals were determined.•The fluvial erosion provokes the resuspension of h.m. from sediments into the water.•Reservoir sediment is accumulating at men rate of 6cm/yr.
•Two periods (1987–1994; 2000–2003) were characterized by long and severe droughts.•The 2000year was the driest year during the observed period.•The significant increasing trend was at Negotin in ...spring and at Novi Sad in autumn.•The significant increasing trend in annual precipitation data was detected at Sombor.•No significant trend was detected in the SPI-12 series at the 5% significance level.
Precipitation and Standardised Precipitation Index (SPI) trends were analyzed by using linear regression, Mann–Kendall and Spearman’s Rho tests at the 5% significance level. For this purpose, meteorological data from 12 synoptic stations in Serbia over the period 1980–2010 were used. Two main drought periods were detected (1987–1994 and 2000–2003), while the extremely dry year was recorded in 2000 at all stations. The monthly analysis of precipitation series suggests that all stations had a decreasing trend in February and September, while both increasing and decreasing trends were found in other months. On the seasonal scale, there were the increasing trends in autumn and winter precipitation series, while on the annual scale the most of the stations had no significant trends. Besides, the decreasing trend was found at the Belgrade and Kragujevac stations, while the other stations had the increasing trend for the SPI-12 series.
In Serbia, as elsewhere in postsocialist Europe, the rise of “civil society” was expected to support a smooth transformation to Western models of liberal democracy and capitalism. More than twenty ...years after the Yugoslav wars, these expectations appear largely unmet. Frontiers of Civil Society asks why, exploring the roles of multiple civil society forces in a set of government “reforms” of society and individuals in the early 2010s, and examining them in the broader context of social struggles over neoliberal restructuring and transnational integration.
•LC–MS/MS was applied for analysis of maize samples from Northern Serbia (2012–2015).•Weather conditions had significant effect on the occurrence of 20 mycotoxins.•AFs were the most dominant in maize ...samples collected from very hot and dry years.•DON, ZEA and its derivatives occurred with high prevalence in samples from 2014.•FUMs were detected with very high prevalence (76%–100%) in samples from each year.
The main objective of this study was to apply a liquid chromatography–tandem mass spectrometric method to investigate the presence of 20 mycotoxins in 204 maize samples harvested in Northern Serbia in the period 2012–2015, including seasons with extreme drought (2012), hot and dry conditions (2013 and 2015) and extreme precipitation (2014). Between 2 and 20 mycotoxins contaminated examined samples. In samples collected from each year, all of six examined fumonisins were detected with very high prevalence (from 76% to 100%). Aflatoxin B1 was detected in 94% and 90% maize samples from 2012 and 2015, respectively. In samples from year 2014, deoxynivalenol, zearalenone and its derivatives were detected in 100% of samples. Furthermore, ochratoxin A (25%) was the most predominant in samples from 2012. The obtained results indicate that changes in weather conditions, recorded in the period of four years, had significant influence on the occurrence of examined mycotoxins in maize.
For the first time, a short hydrofaunistic research of Vlasina Lake, was carried in Serbia, Pčina District, Surdulica Municipalityut. A total 18 free-living fresh water nematods species were found. ...Information on frequency of occurrence and frequency of dominance is given. The study gives first information on the free-living fresh water nematods of the Vlasina Lake. For the first time data are reported on free-living fresh water Nematoda from Serbia.
This book focuses on the hitherto unexplored Hungarian influence on the Habsburg Monarchy’s policy toward Serbia after the 1867 Ausgleich, and it argues that this early period was critical in shaping ...policy after 1871, down to the imposition on Serbia in 1881 of a system of economic and political control.
