Title: Manganese and iron accumulation in a eutrophic, submontane dam reservoir - The role of speciation
Authors: Szarek-Gwiazda Ewa
Abstract: The manganese and iron in the water and sediments of the submontane, eutrophic Dobczyce Dam Reservoir (southern Poland) was partitioned. Manganese and iron occurred mainly in the particulate phases in the water. In the sediments, approximately 77% of Mn was bound to exchangeable carbonate and easily reducible fractions, whereas approximately 90% of Fe was bound to moderately reducible fractions and residues. The cumulation coefficient (K) indicated that Mn, the more “mobile” element, accumulated in lower amounts in the sediments (K=7200) than did Fe (K = 51000). Element partitioning in the sediments was an important factor in determining the level of accumulation.
