“…Elements like cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), chromium (Cr), nickel (Ni) and arsenic (As) are frequently present in sediments due to industrial (Giusti and Taylor 2007;Karadede-Akin and Ünlü 2007;Sakan et al 2010), municipal (Grosbois et al 2006) and mining activities (Svete et al 2001;Bird et al 2010), whereas phosphorous (P) is accumulated in sediments mainly as a consequence of the use of fertilisers at riparian agricultural areas (House and Denison 2002) or is released from municipal sewage treatment plants (Howell 2010).…”

Purpose River ecosystems are under pressure from several different stressors. Among these, inorganic pollutants contribute to multiple stressor situations and the overall degradation of the ecological status of the aquatic environments. The main sources of pollution include different industrial activities, untreated effluents from municipal waste waters and intensive agriculture. In the present study, water, suspended particulate matter (SPM) and sediments of the Sava River were studied in order to assess the pollution status of this river system. Materials and methods Sampling was performed during the first sampling campaign of the EU 7th FW funded GLOBAQUA project in September 2014, at 18 selected sampling sites along the Sava River. In 2014, floods predominated from spring to fall. Water samples were collected to determine the total element concentrations, the dissolved (0.45 μm) fraction and element concentrations in SPM. In order to assure comparative results with other river basins, the fraction below 63 μm was analysed in sediments. The extent of pollution was estimated by determination of the total element concentrations and by the identification of the most hazardous highly mobile element fractions (extraction 0.11 mol L −1 acetic acid) and anthropogenic inputs of elements to sediments (normalization to aluminium (Al) concentration). Concentrations of selected elements were determined by inductively coupled plasma mass spectrometry (ICP-MS). Results and discussion Since during sampling campaign the water level was extremely high, water samples contained high amounts of SPM (in general between 80 and 100 mg L −1). The data of chemical analysis revealed that concentrations of elements in water, SPM and sediments in general increase along the Sava River from its origin to the confluence with the Danube River. Elevated concentrations of chromium (Cr) and nickel (Ni) in SPM and sediments were observed at industrially exposed sites. Concentrations of Cr and Ni in sediments were up to 320 and 250 mg kg −1 , respectively. Nevertheless, these elements were present in sparingly soluble forms and hence did not represent an environmental threat. Phosphorus (P) was found in elevated concentrations (up to 1500 mg kg −1) at regions with intensive agricultural activities and cities with dense population. Conclusions With respect to element concentrations, the pollution of the Sava River is similar to other moderately polluted European rivers. The data from the present study are beneficial for the water management authorities and can contribute to sustainable utilization, management and protection of the Sava River water resources.

“…In addition, chemical analysis of sediments are commonly applied since they reflect spatial and temporal variation of contaminant concentrations of elements (Loring and Rantala 1992;Grosbois et al 2006;Santos Bermejo et al 2003;Tomiyasu et al 2006;de Miguel et al 2005;Meybeck et al 2007;Škrbić andČupić 2004;Woitke et al 2003). Among elements, Cd, Pb, Cu, Zn, Cr, Ni, Hg, and As are often accumulated in sediments as a consequence of industrial (Karadede-Akin and Ünlü 2007; Giusti and Taylor 2007;Sin et al 2001), municipal (Grosbois et al 2006;de Miguel et al 2005), and mining activities (Svete et al 2000;Covelli et al 2001;Hines et al 2006), while intensive rural land use and domestic sewage are a major source of P deposition in sediments (House and Denison 2002;Nguyen 1999). In many cases, the extent of pollution cannot be estimated solely on the basis of the determination of the total content of chemical substances in sediments because bioavailability and toxicity to organisms depend on their chemical forms.…”

The Sava River is the biggest tributary to the Danube River. As a part of the 6th FW EU project, Sava River Basin: Sustainable Use, Management and Protection of Resources (SARIB), ecological status of sediments was investigated. In order to assess the geographical distribution in sediment contamination of the Sava River, inorganic and persistent organic pollutants were analyzed in sediments at 20 selected sampling sites along the Sava River from its spring to its outfall into the Danube River. For comparability of data to other river basins the sediment fraction below 63 microm was studied. Due to complexity of the work performed, the results are published separately ("Part I: Selected elements" and "Part II: Persistent organic pollutants"). In the present study, the extent of pollution was estimated by determination of the total element concentrations and by the identification of the most hazardous highly mobile element fractions and anthropogenic inputs of elements to sediments. To assess the mobile metal fraction extraction in 0.11 mol L(-1), acetic acid was performed (first step of the Community Bureau of Reference extraction procedure), while anthropogenic inputs of elements were estimated on the basis of normalization to aluminum (Al) concentration. According to the Water Framework Directive, the following elements were investigated in sediments: cadmium (Cd), lead (Pb), nickel (Ni), and mercury (Hg). Furthermore, copper (Cu), zinc (Zn), chromium (Cr), arsenic (As), and phosphorous (P) were determined. The analyses of sediments demonstrated slightly elevated values for Hg, Cr, and Ni in industrially exposed sites (concentrations up to 0.6, 380, and 210 mg kg(-1), respectively). However, the latter two elements exist in sparingly soluble forms and therefore do not represent an environmental burden. P concentrations were found in elevated concentrations at agricultural areas and big cities (up to 1,000 mg kg(-1)).

The effect of contaminants on the genomes of Chironomus plumosus L. and Chironomus bernensis Wülker, Klötzli species was studied in the Dunajec River (station 1) and in the littoral of Czorsztyn Reservoir (stations 2 and 3). According to the index of geoaccumulation, the sediments were polluted by cadmium (Cd) and chromium (Cr). Cd concentrations at stations 1, 2, and 3 were 0.71, 0.56, and 1.27 μg g −1 , while Cr concentrations were 841.5, 186.9, and 40.7 μg g −1 , respectively. The pH of sediments ranged from 6.7 to 7.
