As the largest container and resource of metals, sediment has a special role in the fate of
metals. Factors influencing bioavailability of heavy metals in sediment have never been …

Heavy metals, such as arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb),
mercury (Hg) and zinc (Zn), are major environmental problem due to their toxic nature …

Bioavailability is a critical facet of metal toxicity. Although past studies have investigated the
individual role of sediment physico-chemical properties in relation to the bioavailability of …

In order to evaluate the effect of improved oxygen concentrations in overlying surface water
on the redox status, sediment geochemistry and metal bioavailability in metal-polluted …

Recent studies have demonstrated that the toxicity of divalent cationic metals (cadmium,
copper, lead, nickel, and zinc) in sediments can be controlled through binding to acid …

The exploration and proposed mining of sulfide massive deposits in deep-sea environments
and increased use deep-sea tailings placement (DSTP) in coastal zones has highlighted the …

In aquatic systems worldwide, heavy metal pollution has been increasing alongside rapidly
growing anthropogenic activities, and most heavy metals are stored in sediments. Overlying …

The release of sediment-bound heavy metals can have a significant influence on river water
quality. Generally speaking, variations of pH and oxygen are among the most important …

Sulfide minerals are an important sink for metals within anoxic sediments. Extraction
techniques using cold HCl to measure the concentration of sulfide mineral associated trace …

This study was performed to determine the distribution and chemical fractions of five heavy
metals (Cd, Cr, Cu, Pb, and Zn) in sediment from three sampling areas in Swan Lagoon, and …
