Zinc is a ubiquitous metal, acting both as an essential and a toxic element to organisms
depending on its concentration and speciation in solution. Human activities mobilize and …

Zinc (Zn) is an essential trace element widely present in rivers and plays a crucial role in
ecosystems. Human activities have led to the extensive migration and dissemination of Zn in …

Abstract Characterization of the spatial distribution and speciation of iron (Fe) in Fe-modified
biochars is critical for understanding the mechanisms of contaminant removal. Here …

The use of multiple isotopic ratios and statistical methods can substantially increase the
reliability and precision of determining contamination sources and pathways. In this study …

Degraded water quality and environmental impacts caused by weathering of sulfide-bearing
mine wastes are a legacy remaining at many historical mine sites. Release and mobilization …

The contamination of coastal environments by metallurgical wastes involves multiple
biogeochemical processes; accordingly, understanding metal behavior and risk evaluation …

Toulon bay is severely impacted by metal contamination induced by past and recent naval
activities. In this work, Cu, Zn and Pb isotope compositions and elemental concentrations of …

Abstract Zinc (Zn) and cadmium (Cd) are two important biological-sensitive elements, and
their isotopes are strongly fractionated during biological processes. To develop the potential …

Fe-modified biochars (FeBC) are effective antimony (Sb) removal materials; however, the
removal mechanisms require further investigation. In this study, aqueous Sb (III) and Sb (V) …

Fe-loaded biochar (FeBC) has been considered for Sb (III) adsorption, but the effects of
oxygen (O 2) on the adsorption need further investigation. Liquid-/solid-phase analyses …
