In a study of the bioaccumulation of metals as colloid complexes and free ions by the marine brown shrimp, Penaeus aztecus [29] the colloids were isolated and concentrated from water obtained from Dickinson Bayou, an inlet of Galveston Bay, Texas, using various filtration and ultrafiltration systems equipped with a spiral-wound 1 kDa cutoff cartridge. The total colloidal organic carbon in the concentrate was found to be 78 lmgdm 3. The shrimps were exposed to metals (Mn, Fe, Co, Zn, Cd, Ag, Sn, Ba and Hg) as radiolabelled colloid complexes, and free-ionic radiotracers using ultrafiltered seawater without radiotracers as controls. The experiments were designed so that the animals were exposed to environmentally realistic metal and colloid concentrations. [Pg.367]

At about the time that Honeyman and Santschi published their colloidal pumping hypothesis, lab and field studies showed that thorium and other metals in seawater are, indeed, associated with colloids (Baskaran et al., 1992 Moran and Buesseler, 1992 Moran and Moore, 1989 Niven and Moore, 1988). Subsequently, many more studies have demonstrated that colloids are abundant in seawater and that they play an important role in the marine biogeochemical cycles of organic carbon and of many trace elements (Guo and Santschi, 1997). [Pg.3103]

Generally speaking, a direct relationship between uranium concentration and increasing organic carbon content exists in marine black shales. Uranium content is also directly related to the colloidal size ranges of such sediments. [Pg.21]
