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 …

This review of 19 chemical approaches used in assessing sediment quality are classified
into empirical, mechanistic and sediment quality indices (SQI) groups. Empirical sediment …

Chemical speciation of heavy metals (Zn, Pb, Cu, and Cd) was studied to evaluate the
contamination status and associated risks and to constrain the sources of heavy metals in …

Morocco is one of the most affected regions by heavy metal pollution worldwide. In this
study, two ecosystems in Agadir Bay, southern Morocco, were studied seasonally, using …

Microplastics (MPs) are considered to influence the bioavailability of heavy metals through
direct adsorption, but this neglects the distribution of heavy metal chemical speciation …

Sediment quality guidelines (SQGs) are a fundamental component of sediment quality
assessment framework, frequently used in the first tier of assessment to predict the potential …

Abstract Heavy metal (Cr, Cu, Ni, Pb, and Zn) pollution and the risks posed by the heavy
metals in riverine sediments in a mountainous urban-belt area (MB), a mountain–plain …

Identifying the mobilization mechanisms and predicting the potential toxicity risk of metals in
sediment are essential to contamination remediation in river basins. In this study, a …

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 …

The occurrence, toxicities, and ecological risks of five heavy metals (Pb, Cu, Cd, Zn and Ni)
in the sediment of Taihu Lake were investigated in this study. To evaluate the toxicities …
