RT Journal Article ID 417d6a712871ad35 T1 Bottom Sediments of Reservoirs as a Potential Source of Secondary Pollution of the Aquatic Environment by Heavy Metal Compounds JF Hydrobiological Journal JO HYD YR 2001 FD 2001-02-01 VO 37 IS 1 OP 14 AB The article reports the results of long-term investigations of pollution of bottom sediments in the Dnieper water bodies by heavy metals. The most probable ways of heavy metals exchange between the bottom sediments and the contacting aquatic environment are considered. It is shown that the intensity of exchange processes depends not on the total content of heavy metals in bottom sediments, but rather on their existing forms in composition of both the solid substrata and interstitial solutions. The assessment is made of migration mobility of the investigated heavy metals and their exchange capacity.
