“…Acidification of water is mainly to be attributed to the strong hydrological and hydrochemical influence of precipitation, which often has an acidic reaction and very low total hardness [9,10]. This entails very poor buffering of the water, as the water often does not contain enough alkalis that can neutralize the ions that cause acidification of the reservoir water [11]. Flowing waters feeding the reservoir are of similar importance.…”

“…The leaching of acidic soils is also one of the causes of water acidification. Alkalization of waters is the opposite situation, and its causes can be traced to human activities related to over-fertilization of soils in the basin and intensive fish farming [11]. Such chemical and bio-chemical transformations are also the result of very intensive photosynthesis in water [12].…”

“…Actions on a chemical basis are mainly associated with water activity and involve oxidation, reduction, and carbonation, among others. Another cause of rock disintegration is the influence of microorganisms, whose secretions lead to the gradual disintegration of rock material [11]. This biological part is also enriched by the activity of plants and animals.…”

“…The anthropogenic side of acidification is the effect of industrial and agricultural activity. It results from the release of sulfur and nitrogen compounds into the environment [8][9][10][11][12]. Among others, as a result of changes in water and sediment pH, increased metal leaching and then movement in the reservoir take place [13].…”

“…If the pH is low, the process of metals released by desorption from the sediment into the water is more intense. Another relationship concerns the level of organic matter, in which higher amounts are related to a greater capacity to accumulate (chelate) metals and inactivate them in the sediment, as organic matter can both dissolve and precipitate the metals [11,13].…”

Sediments from three rivers in south-western Poland and their tributaries were used in a laboratory experiment on metal (Al, Cu, Ni, Cd, Zn, Fe, Mn) release. Metal migration was studied under different pH (pH 3.93, pH 7.29, pH 9.59) during 96 h. Al concentration was the highest in Bystrzyca and lowest in Strzegomka; other metal concentrations were highest in Nysa Szalona and lowest in Strzegomka. The values of pH and electrolytic conductivity increase throughout the experiment in acidic and neutral environments. Water pH decrease was observed under alkaline conditions, but conductivity reached higher values with time. The aluminum release showed an increase in values followed by a decrease. The highest aluminum amounts were released from the sediment from Nysa Szalona and the lowest from Strzegomka. The greatest aluminum migration was observed in the acidic medium. Similar observations were made for Mn and Zn: Strzegomka < Nysa Szalona < Bystrzyca. For Cu, Cd, Fe and Ni, the highest values were recorded in sediments in alkaline conditions. The amount of metals migrating from sediments to water remains at a similar level as presented by other researchers. More metals are released under acidic conditions. The most intensive migration of metals is noted at the beginning of the experiment. This experiment shows the existing trend of metals migration from the sediments to the over-bottom water, which is important from the point of view of the use of water for drinking purposes. Satisfactorily, the sediments in varied environments behave predictably enough that the quality of raw water under these conditions is not compromised, which is confirmed by environmental and health standards. The research performed concerns a specific area of southwestern Poland, for which this type of research has not been conducted.
