“…In contrast the As concentrations were within of ranges for affected rivers from polluted European rivers (4.5-45 lg L -1 ) and for rivers mining influenced (\0.2-7,900 lg L -1 ) (Plant et al 2005). Similarly, the dissolved concentrations of Cd, Cu and Pb were comparable to and within the ranges found in rivers from the Danube and Marisa drainage basins (Cd, \0.3-9.4 lg L -1 ; Cu, \0.8-250 lg L -1 ; Pb, \0.3-200 lg L -1 ), with the exception of the Zn levels, which were two times higher than those from Eastern Europe (Zn,\1-460 lg L -1 ) (Bird et al 2010). However, when the levels are compared to the maximum levels found in streams from southern Ecuadorian rivers impacted by gold mining (Carling et al 2013) or miningaffected tributary streams from the Danube basin (Bird et al 2010), our values are low.…”

“…However, our results are low compared to those from watersheds influenced by metal mining activities in regions of Europe or South America. In the Danube, levels as high as 33 mg kg -1 for Cd, 8,088 mg kg -1 for Cu, 1,700 mg kg -1 for Pb, and 2,010 mg kg -1 for Zn have been reported (Bird et al 2010). In Ecuadorian rivers impacted by gold mining, concentrations as high as 46,049 mg kg -1 for As, 104 mg kg -1 for Cd, 9,134 mg kg -1 for Cu, 34 mg kg -1 for Hg, 6,646 mg kg -1 for Pb, and 9,792 mg kg -1 for Zn have been reported (Carling et al 2013).…”

“…The release of contaminant metals into river environments within mining-affected river systems generally results from (Bird et al 2010): acid mine drainage; the release of waste slurries that contain solute and particulateassociated metals; dumping of mining waste that is subsequently leached or dispersed downstream; and the occurrence of mine tailings dam failures. The frequency of spills associated with mine tailings dam failures is surprisingly high; e.g., Villarroel et al (2006) reported that during the period 1970-2003, there were at least 59 major metal-related tailings impoundments that failed worldwide, with a volume of material released ranging from 5,500 to 1,300,000 m 3 .…”

Concentrations of arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), silver (Ag) and zinc (Zn) were evaluated in water and suspended sediments of the upper waters of San Lorenzo River in NW Mexico following a mine tailing spill. Except As (6.64-35.9 µg L(-1)), dissolved metal concentrations were low (Ag <0.06-0.22; Cd 0.01-0.34; Cu 4.71-10.2; Hg 0.02-0.24; Pb <0.15-0.65; Zn 86-1,080 µg L(-1)) and were less than the upper limits established by UNEP (Water quality for ecosystem and human health, 2nd edn. United Nations Environment Programme Global Environment Monitoring System/Water Programme, Burlington, 2008), EPA (2014) and the Mexican regulation (NOM 1994). In contrast, the suspended metal concentrations were high (As 91.4-130; Ag 22.1-531; Cd 3.14-6.30; Cu 65-123; Hg 0.47-1.09; Pb 260-818; Zn 742-1,810 mg kg(-1)) and most of samples exceeded the probable effect level of the Canadian Sediment Quality Guidelines for the Protection of Aquatic Life.

“…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).…”

Elements in water, suspended particulate matter and sediments of the Sava River

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.

“…Concentrations of Cd, Cu, Pb and Zn in river water were found to be highest in close proximity to locations of Cu and PbZn mining regions in the Maritsa catchment. Downstream dispersal of solute metals in these catchments and into the River Danube, was found to be limited by physical dilution and a well-buffered pH environment (Bird et al, 2010).…”

Problem statement: Serious health problems and other economic costs related to water treatment, remediation and locating a new water supply, become an evidence of water pollution caused by human activities. The main problems of the Danube River basin are associated with nutrients, organic pollution and hazardous pollutants. The aim of the study is to assess the surface water of the Danube in Budapest for sustainability of human and environment health. The relation between O 2 and Chl-a content of the samples, clearly shows that the cause of high dissolved O 2 content in the water lies in accelerated primary production. Enumerations of both total and fecal Coliforms are continuously growing during the investigation periods. These results suggested that bacteriological properties can be a specific indicator of fecal contamination and organic pollution. With large numbers of new chemical substances entering the river ecosystem, continuous monitoring systems for their detection will become increasingly important with respect to environmental effects they produce, in addition to other toxic effects. The challenges to continuous physical, chemical, biological and bacteriological monitoring will be immense.
