“…The Sava is also one of the main sources of drinking water for its riparian population. Sources of PTE in the Sava's riparian zones are diverse, relating mostly to chemical weathering of parent material and various anthropogenic factors (Vertačnik et al 1995;Orescanin et al 2004;Crnković et al 2008;Markovics et al 2010;Vuković et al 2011;Šajn and Gosar 2014;Ščančar et al 2015). These factors include industrial and intensive agricultural activities, urbanization, and, in the Sava's lower reaches, non-treated municipal sewage (Komatina and Grošelj 2015).…”

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.

“…Presence of various stressors in the environment (primarily organic and inorganic pollutants) can influence the integrity of DNA molecules in aquatic organisms which can have consequences on individual and population levels [ 4 ]. In the study of Ščančar et al [ 5 ], moderate pollution by substances with nothworty genotoxic potential such as polycyclic aromatic hydrocarbons, pesticides and metalls (Hg, Cr, Ni) was detected at several sites along the Sava River. Therefore, ecogenotoxicological bioassays could become essential as early warning systems for the possible deterioration of the ecosystem health.…”

In this study we have performed a comprehensive genotoxicological survey along the 900 rkm of the Sava River. In total, 12 sites were chosen in compliance with the goals of GLOBAQUA project dealing with the effects of multiple stressors on biodiversity and functioning of aquatic ecosystems. The genotoxic potential was assessed using a complex battery of bioassays performed in prokaryotes and aquatic eukaryotes (freshwater fish). Battery comprised evaluation of mutagenicity by SOS/umuC test in Salmonella typhimurium TA1535/pSK1002. The level of DNA damage as a biomarker of exposure (comet assay) and biomarker of effect (micronucleus assay) and the level of oxidative stress as well (Fpg—modified comet assay) was studied in blood cells of bleak and spirlin (Alburnus alburnus/Alburnoides bipunctatus respectively). Result indicated differential sensitivity of applied bioassays in detection of genotoxic pressure. The standard and Fpg—modified comet assay showed higher potential in differentiation of the sites based on genotoxic potential in comparison with micronucleus assay and SOS/umuC test. Our data represent snapshot of the current status of the river which indicates the presence of genotoxic potential along the river which can be traced to the deterioration of quality of the Sava River by communal and industrial wastewaters. The major highlight of the study is that we have provided complex set of data obtained from a single source (homogeneity of analyses for all samples).

“…As bottomdwelling fish that feeds primarily on invertebrates (Piria et al, 2016), N. melanostomus may be affected by severe pollutants throughout its life cycle. The higher toxic potential along the Sava River was identified at specific "hot spots" and in its lower reaches (Källqvist et al, 2008;Ščančar et al, 2015;Marković et al, 2018). The sampling sites in this study were characterised by different environmental factors and conditions, resulting in higher anthropogenic pollution around BGG and further downstream (Milačič et al, 2017).…”

“…The sampling sites in this study were characterised by different environmental factors and conditions, resulting in higher anthropogenic pollution around BGG and further downstream (Milačič et al, 2017). BGG is the site with the abundant population of N. melanostomus (Piria et al, 2016) and the high environmental stress (Ščančar et al, 2015;Marković et al, 2018;Zuliani et al, 2019). This could be a reason for the higher values of the bilateral asymmetry of N. melanostomus taken from the most downstream point (BGG) in this study.…”

Round goby Neogobius melanostomus is one of the three invasive Ponto-Caspian gobies found in the Sava River basin in Croatia. It has a negative effect on the native ecosystems and is more abundant in highly polluted areas. The objective of this study was to determine the fluctuating asymmetry of four morphometric characters, as well as otolith width and length. Thirty individuals of N. melanostomus were collected and analysed at two sampling sites in the main course of the Sava (Babina Greda, Slavonski Brod) and in a modified habitat (Sava-Odra canal). The squared coefficient of asymmetry variation was used to analyse potential differences between populations. We identified variations in the asymmetry values of the analysed characters, as well as otolith width and length between sampling sites. The highest fluctuating asymmetry was observed in individuals at the Babina Greda sampling site, which could be due to high environmental stress. The results of the study show that the study of fluctuating asymmetry can be used on invasive fish species as a simple approach to identifying habitat quality.
