“…To determine readily soluble, potentially bioavailable element concentrations, acetic acid extraction was applied (Quevauviller et al 1997;Milačič et al 2010). Approximately 2 g of moist soil sample was weighed into a 40-mL centrifuge tube with 20 mL 0.11 mol L −1 acetic acid added.…”

Purpose Riparian zone contamination is a growing problem for several European catchments due to high anthropogenic pressures. This study investigates As, Cd, Cr, Cu, Ni, Pb, and Zn concentrations in the Sava River riparian zone, characterized by wide agricultural areas, various geological substrates, and different types of industrial pollution. The accumulation and mobility of these elements were studied because they are listed as priority substances in the Water Framework Directive and environmental objectives for surface waters. Materials and methods Sampling was performed during the sampling campaign of the EU 7th FW-funded GLOBAQUA project in September 2015 during a low-water event. Soil samples were collected along the Sava River at 12 selected sampling sites, from a depth of 0–30 cm, at a distance of 10–15 m from the river bank. The extent of pollution was estimated by determining total and readily soluble element concentrations in the soils. Potential ecological risk and the source of the selected elements in the soils was determined using the enrichment factor (EF), potential ecological risk index (RI), and statistical methods such as the principal component analysis (PCA) and multiple linear regression analysis (MLRA). Results and discussion This study showed that concentrations of the selected elements increase along the Sava. In terms of origin, PCA and MLRA indicated that Cr and Ni in soils are predominantly lithogenic, while As, Cd, Pb, and Zn are both lithogenic and anthropogenic (ore deposits, industry, and agriculture). PCA singled out Cu since its origin in soil is most probably from specific point-source pollution. EF was generally minor to moderate for most of the examined elements, apart from Cu, for which the EF was significant at one sampling site. Overall ecological risk (RI) fell within the low-risk category for most sites, apart from Belgrade sampling site (BEO), where high total Cd content affected individual and overall ecological risk indicators, indicating Cd could represent a considerable ecological risk for the downstream riparian zone. Conclusions At downstream sites, there was a noticeable increase in PTE content, with Cd, Cr, Ni, and Zn exceeding the proposed threshold values for European soils, indicating rising contamination in riparian soils. In terms of the ecological risk, only Cd could pose a potential ecological threat for the downstream riparian zone.

“…Although the national environmental agencies monitor the quality of the Sava River on a regular basis, the sediment quality has not been assessed prior to our investigation supported by the EU FP6 Sava River Basin: Sustainable Use, Management and Protection of Resources (SARIB). The aim of our work was a comprehensive study to determine the extent of pollution according to Water Framework Directive recommendations (Commission Directive 2002/62/EC 2002Commission Directive 2000/60/EC 2000 and includes selected elements (A complex investigation of the extent of pollution in sediments of the Sava River: part 1: selected elements; Milačič et al 2009) and persistent organic pollutants (part 2, presented herein) in sediments along the Sava River.…”

Sediment pollution of the biggest Danube tributary, the Sava River, was investigated within the sixth framework European Union project "Sava River Basin: Sustainable Use, Management and Protection of Resources" (SARIB). The extent of pollution was estimated by determining the amount of inorganic and persistent organic pollutants in sediment samples at 20 selected sampling sites along the Sava River. For the purpose of clarity, the findings are presented and published separately (part I: selected elements and part II: persistent organic pollutants). This study presents an investigation into the presence of organic pollutants in the Sava River sediment. According to the Water Framework Directive, the following persistent organic pollutants were investigated: polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), selected chlorinated pesticides and organotin compounds. The results reveal that PAHs were present in moderate concentrations (sum of 16 PAHs: up to 4,000 ng g(-1)) and their concentrations increased downstream. Concentrations of PCB were low (sum of seven indicator PCBs: below 4 ng g(-1)) and among the pesticides analyzed only p,p-dichlorodiphenyltrichloroethane was found in moderate concentrations at two sampling sites in Croatia (up to 3 ng g(-1)) and hexachlorobenzene was found in a high concentration in the city of Belgrade (91 ng g(-1)), although the use of these persistent pesticides has been banned for decades. Repeated sampling at the same location revealed point pollution near Belgrade. Among the organic pollutants surveyed, organotin compounds were not detected. Overall results reveal the presence of persistent organic pollutants in 20 of the Sava River sediments tested that is, in general, comparable or lower than the levels in the Danube River and other moderately polluted European rivers.

“…There have been few chemical data available in the Serbian parts of the Danube and its biggest tributary the Sava up to now, especially information regarding metal, polycyclic aromatic hydrocarbon (PAH) and polychlorinated biphenyl (PCB) levels (Heath et al 2010;Milačič et al 2010;Vranković & Slavić 2015). Regarding the presence of cadmium (Cd), lead (Pb), nickel (Ni), mercury (Hg), copper (Cu), zinc (Zn), chromium (Cr), arsenic (As) and phosphorous (P), the Sava River and the Danube River exhibit similar extents of pollution with these elements .…”

The present study aims to assess the biological effects of different environmental pollution on the Asian clam Corbicula fluminea. Biomarkers indicative of oxidative stress (superoxide dismutase, SOD; catalase, CAT; glutathione peroxidase, GPx; glutathione reductase, GR; and the phase II biotransformation enzyme glutathione-S-transferase, GST) were measured in clams collected within the Serbian sector of the Danube River Basin at three locations: Višnjica, Zemun and Bela stena. Clams from Višnjica exhibited significantly higher SOD, CAT and GST activities than clams from the other two locations (p < 0.05), whereas GPx and GR activities do not have such a marked pattern. An alteration in the activity of SOD, CAT and GST reflects the presence of certain pro-oxidative chemicals that can lead to oxidative stress in clams at the Višnjica site. In conclusion, the noted antioxidant disparities among clam populations from different locations reflected physiological sensitivity of C. fluminea to environmental change, supporting its use as a sentinel organism in biomonitoring investigations.
