“…An increasing trend in Cl À concentration with time has actually been observed in the upper Oder River, which was possibly caused by the inflow of saline waters from coal mine drainage [15]. Increased Cl loading from agricultural activities can also have affected the Cl À concentration in the river.…”

a b s t r a c tDistribution of 36 Cl/Cl ratios in a river-recharged aquifer was investigated in the Oderbruch area, northeastern Germany. The aquifer is confined up to 3.5-4 km inland, where it changes to an unconfined condition. The 36 Cl/Cl ratios in the confined area were in the range between 4.6 Â 10 À14 and 23.1 Â 10 À14 , showing a peak at 2-3 km away from the river. A plot of 36 Cl/Cl vs. reciprocal Cl À concentrations indicated possible effect of the Cl À concentration variation on the observed 36 Cl/Cl ratios. After accounting for this effect, the estimated 36 Cl fallout rates for the last 30 yrs show reasonable agreement with the Dye-3 data and the mid-latitude background value. The results suggest that a local 36 Cl fallout curve can be constructed from groundwater when dispersive mixing is of minor importance.

“…In the investigated sediments the organic matter content exceeding roughly 10% is an additional feature indicating a large overall content of pollutants in the river at the time of their deposition. Indeed, it is known that the upper Odra and the upper Vistula were among the most polluted rivers in Europe during the post-World War II period of rapid industrialization (Korol et al, 2005;Absalon and Matysik, 2007). Also, a high content (reaching 70%) of sewage effluents in river discharges was reported at the end of the nineteenth century for drainage basins of the upper Vistula and the upper Odra (Czaja, 2005).…”

Channelization of the severely polluted Odra and Vistula Rivers in Poland induced intensive accumulation of finegrained deposits rich in organic matter and heavy metals. These sediments have been identified in vertical profiles in a narrow zone along river banks both in groyne-created basins and on the floodplain. Grain size, organic matter, zinc (Zn), lead (Pb), copper (Cu) content and cesium-137 ( 137 Cs) was used for sediment dating and, stratigraphy and chemistry have been diagnostic features for these deposits, named industrial alluvium. In the most polluted river reaches stabilized by bank reinforcements and groynes, 2-m-thick slack water groyne deposits are composed of uniform strata of polluted silts with organic matter content over 10%, Zn content over 1000 mg/kg and average Cu and Pb over 100 mg/kg. The average rate of sediment accretion in groynes is higher than on the floodplain and reaches 5 cm/yr. Stratification which appears at higher levels in the groyne fields and on the levees reflects a change from in-channel to overbank deposition and is typified by dark layers separated by bright, sandy, and less polluted strata. Stratified, 4-mthick, sediment sequences have been found in groyne fields of incised river reaches. The average rate of sediment accretion in these reaches is of the order of 5 cm/yr. In stable and relatively less polluted river reaches, vertical-accretion organic deposits are finely laminated and the average rate of deposition amounts to a few millimeters per year. Investigations indicate that groyne construction favors conditions for long-term storage of sediments at channel banks. For this reason, groynes should be considered as structures that efficiently limit sudden release of sediment-associated heavy metals stored in channels and in floodplains of the historically polluted rivers.

“…On the contrary, the levels of COD, that is the expression of organic substances chemically oxidizable, ranged widely in the five classes of pollution. High COD and low BOD values are generally associated with the presence of non-degradable organic compounds in river waters, or to high concentrations of heavy metals, that kill the micro-organisms (Simeonov et al 2003, Kotti et al 2005, Absalon and Matysik 2007. In the cases presented here, given the not low concentrations of E. coli, the worst distribution of COD, with respect to BOD, is likewise an indication of an escape of organic waste with limited biodegradability.…”

According to the European Water Framework Directive, Italy introduced two aggregate indices for evaluating the ecological status of rivers, called respectively LIM (Pollution Level of the Macro-descriptors) from 2000 to 2008, and LIM eco from 2010 onwards. The LIM index considered the % of Dissolved Oxygen (DO%), ammonium nitrogen (NH 4 -N), nitrate nitrogen (NO 3 -N), total phosphorus (P), Biochemical Oxygen Demand (BOD 5 ), Chemical Oxygen Demand (COD), and Escherichia (E.) coli, while LIM eco considered only DO%, NH 4 -N, NO 3 -N, and total P. The aim of this study was to evaluate differences between LIM and LIM eco for defining quality status of freshwaters. For this purpose, data obtained during an annual monitoring campaign of four main rivers of southern Italy were used to calculate both indices. LIM eco seems to return the quality status of a river better than LIM when the state of the water body is more compromised, while there is a substantial consistency when the river quality is at a medium/high level. Indeed, LIM intended to give a 'traditional' classification of freshwaters, integrating environmental and ecological descriptors, while LIM eco focuses on the trophic status of freshwaters, considering only nutrients and oxygen, essential for the aquatic biological communities and it does not consider organic load and microbiological contamination.
