Distribution trace elements among solid-phase

BINDING AND DISTRIBUTION OF TRACE ELEMENTS AMONG SOLID-PHASE COMPONENTS IN ARID ZONE SOILS...

Carbonates, organic matter, Fe and Mn oxides, and clay minerals play important roles in controlling overall reactivity of trace elements in soils and sediments. This chapter addresses the interaction of trace elements with carbonates, organic matter, Fe and Mn oxides and clay minerals. Analytical techniques for trace element speciation in solid-phase and their distribution among various solid-phase components in arid and semi-arid soils are reviewed. Solubilities of trace elements in solid phases and their mineralogical characteristics in arid and semi-arid soils also are discussed. 

Until now the attainment of these results was not possible, as few data are available to describe the trace metal concentrations in the Southern Ocean (5-11). In order to contribute to the knowledge of the distribution of trace elements and of the biological cycles in Antarctica over the past twelve Italian expeditions, attention was focused, among others, on trace metals in solid and in dissolved phases (12 29).
