The toxicity of chemicals in sediments is influenced by the extent that chemicals bind to the
sediment. It is shown that acid volatile sulfide (AVS) is the sediment phase that determines …

Examinations of rare earth element (REE) adsorption in seawater, using a variety of surface-
types, indicated that, for most surfaces, light rare earth elements (LREEs) are preferentially …

We present REE patterns determined by isotope dilution mass spectrometry from 20
Precambrian banded iron formation (BIF) samples, ranging in age from 3.4 to 0.65 Ga. The …

Shipboard studies were performed for testing the classical hypothesis that Antarctic
phytoplankton suffers from a deficiency of Fe. In a suite of 5 experiments over 8 to 12 d …

The complexation of trace metals by organic ligands has long been proposed to play a
significant role in determining trace metal speciation in seawater. However, analytical …

Copper speciation has been studied at an oligotrophic station in the southwestern Sargasso
Sea to determine the distribution of Cu binding ligands and evaluate their potential sources …

Simultaneous uptake of Ce (III), Eu (III), Gd (III), Yb (III), and Zn (II) by an organic substrate,
Ulva lactuca L., was examined in seawater. REE behavior was observed to be strongly …

Dissolved zinc and copper and free cupric ions were present at high concentrations in water
from the Elizabeth River estuary (a polluted tributary of the southern Chesapeake Bay) when …

Formation constants for zinc complexation by bicarbonate, carbonate, and oxalate, on the
molal concentration scale, were determined through observation of aqueous/tributyl …

A newly developed method Is presented for the measurement of the ability of organic
ligands In seawater to form complexes with metal Ions. Organic ligands (nominal molecular …
