Populations and metropolitan centers are accumulated in coastal areas around the world. In
view of the fact that they are geographically adjacent to coasts and intense anthropogenic …

Thallium (Tl) is a dispersed trace metal showing remarkable toxicity. Various anthropogenic
activities may generate Tl contamination in river sediments, posing tremendous risks to …

This study investigates the relationships among Ni, Cd and Pb's different chemical forms
determined by different methodologies in coastal and transitional waters across a broad …

In this study, the historical variation (210 Pb dating) and distribution of toxic trace metals in
sediments of the Nanliu River Estuary (NRE) were studied to understand the spatiotemporal …

We analyze Pb content and Pb isotope ratios in 29 surface sediments and one sediment
core from the eastern Beibu Gulf, Southern China. The results indicate that obvious Pb …

One hundred soil samples were collected from urban spaces, in Lisbon, Portugal, in two
surveys that were carried out in consecutive years, to assess the potential adverse human …

In continental margins, canyons appear to act as natural conduits of sediments and organic
matter from the shelf to deep basins, providing an efficient physical pathway for transport …

Continental margins play a key role in the cycling of natural and anthropogenic trace metals
(TMs) as pathways at the interface between landmasses and deep ocean basins but also as …

Platinum is one of the least abundant elements in the earth crust with an average
concentration of 0.51 ng g− 1, but its use in several human activities (mainly automobile …

Catalytic converters in automobiles have significantly increased the input of platinum group
elements (PGE) to the environment, and their coupled geochemical behavior has been …
