“…The contamination levels of Sr were low in the protected oxbow and the two fishing oxbows (FO1 and FO3), while in the case of fishing oxbow 2 (FO2) and the sewage-contaminated oxbow, moderate levels of contamination were found for Sr. Furthermore, our results indicated that the contamination of the River Tisza with Cu, Pb, and Zn from the mining area in Northern Romania has continued up to the present day similar to earlier studies (Osán et al 2007;Bird et al 2008;Simon et al 2017).…”

We assessed contamination in the Upper Tisza region (Hungary, Central Europe), analyzing the elemental concentrations in sediment cores of oxbows. Our hypothesis was that the metal contamination which occurred in the year 2000 and which came from the mining area in Transylvania (Romania) may be detected even 15 years after the contamination, based on the vertical profile of sediment cores. Sediment cores were collected from five oxbows, and the following elements were measured with microwave plasma-atomic emission spectrometry (MP-AES): Cu, Cr, Ba, Fe, Mn, Pb, Sr, and Zn. Among the oxbows studied, there was one protected oxbow, three were used for fishing, and one was contaminated with sewage. Our results indicated that the year of contamination is still observable in the vertical profile of the sediment cores. The pollution index (PI) was used to characterize the sediment enrichment of metal elements in the sediment cores. In the case of Cu, Pb, and Zn, the contamination which originated in the year 2000 was detected in the layers of the sediment cores. The contamination levels of Cu, Pb, and Zn were high or moderate in the studied oxbows. All oxbows were moderately contaminated by Mn, while a moderate level of contamination was found for Fe in the protected oxbow, one fishing oxbow, and the sewage-contaminated oxbow. In the fishing oxbows, a low level of contamination was found for Fe. The contamination level of Sr was low in the protected oxbow and in the two fishing oxbows, while in one of the fishing oxbows and in the sewage-contaminated oxbow, a moderate level of Sr contamination was found. The pollution index scores indicated that the contamination level for Ba and Cr was low in the sediment cores of the oxbows studied. Our results indicated that the contamination of the Tisza River from the mining area in Northern Romania has been continuous and is still ongoing.

“…Thereafter, trace element concentrations decreased in both the Szamos and the Tisza (Óvári et al, 2004). However, recent pollution of the River Szamos with Pb, Cd, Cu and Zn has occurred due to intensive mining activities in Romania (Simon et al, 2017).…”

Highlights Three different feeding groups of chub from the River Szamos were analyzed.  Feeding groups were differed based on the trace element patterns of tissue. Generally, the highest concentrations of elements were found in the juveniles. Only the hepatic copper concentrations showed positive correlation with fish age. The juveniles of chub can be used as a bioindicators of the recent metal pollution.

“…In the year 2000, two major mining accidents in the Tisza's upper catchment area released huge amounts of cyanide and heavy metals into the Tisza through its tributaries, damaging its ecosystem (Soldán et al 2001). The impact of the cyanide and heavy metal spills on the flora and fauna of the Tisza has been extensively evaluated, as well as the metal contamination status of the river itself (Hum and Matschullat 2002;Bird et al 2003;Fleit and Lakatos 2003;Lakatos et al 2003;Óvári et al 2004;Kraft et al 2006;Woelfl et al 2006;Osán et al 2007;Sakan et al 2009;Sakan and Đorđević 2010;Sakan et al 2013;Simon et al 2017). However, a limited number of studies focused on the impact of the metal-contaminated river on its active floodplain, and those studies are restricted to the Upper and the Middle Tisza regions (Black and Williams 2001;Szabó et al 2008;Prokisch et al 2009;Babka et al 2011;Csedreki et al 2011;Győri et al 2015).…”

Assessing the impacts of the main river and anthropogenic use on the degree of metal contamination of oxbow lake sediments (Tisza River Valley, Hungary)

Purpose Oxbow lakes, reaches that were cut off from a river during river straightening works, can accumulate during flooding metal-rich suspended sediments transported by a river from mining-impacted source areas and other anthropogenic sources. Additionally, the anthropogenic use of oxbow lakes may significantly impact the sediment-bound metal concentrations. The aim was to determine the dominating effect in the sediments' enrichment in heavy metals. Materials and methods We collected surface sediments (< 10-cm depth) from seven oxbow lakes once connected to the Tisza River (a transboundary river in Central and Eastern Europe). Four of the oxbows were located on the active floodplain, while three oxbows were at the reclaimed side (i.e., outside the flood defense levee). The sediment samples were subjected to total metal analyses (Cd, Co, Cr, Cu, Ni, Pb, and Zn) and sequential chemical extractions. Results and discussion Contamination indices (geoaccumulation index (Igeo) and pollution load index (PLI)) show a moderate but significant metal pollution of oxbow lakes situated on the active floodplain (I geo (Pb) 0.95-1.25, PLI 2.1-2.8) and an overall unpolluted to slightly polluted status of those at the reclaimed side (I geo (Pb) − 0.36-0.51, PLI 1.3-1.7). Additionally, the geochemical fractionation of the target metals showed that Cd and Zn were the most labile (Cd 29-48%, Zn 18-37% of nonresidual proportions), indicating their environmental significance. Conclusions Canonical discriminant analysis of the sediment-bound metal concentrations revealed the prevalent role of the river connection over the anthropogenic use in controlling the metal enrichment of oxbow sediments.
