| Abstract: | Sequential, selective chemical extraction was used to separate estuarine (Mobile Bay, Ala.), freshwater (Ashtabula, Ohio), and marine (Bridgeport, Conn.) sediments into the fractions (a) dissolved in sediment interstitial water; (b) adsorbed on mineral surfaces; (c) associated with hydrous iron and manganese oxides and hydroxides; (d) associated with sediment organic matter and sulfides; and (e) bound within the lattice of crystalline minerals and the interlayer positions of phyllosilicate (clay) minerals. Separate sediment extractions using the Elutriate Test were also conducted. Manganese, nickel, cadmium,. zinc, and arsenic concentrations were determined in each extractant. Nickel, cadmium, zinc, and arsenic concentrations were highest in fractions (e), (d), (d), and (c), respectively. Manganese concentration was highest in fraction.(d) in sediments from Mobile Bay and Ashtabula arid in fraction (e) in Bridgeport sediment. Manganese concentration determined in the standard elutriate was correlated with its concentration in sediment fractions (a), (b), and (c). Zinc concentration determined in the standard elutriate was correlated with its concentration in sediment fractions (c) and (d). However, nickel, cadmium, and arsenic concentrations were not correlated with their respective concentrations, in any sediment fraction when all data were, considered, although some site-specific correlations were noted for arsenic and nickel. |
