A method to reproduce pH and Eh environmental changes due to sediment resuspension

open access: yesMethodsX, 2022
During the last decades, metals have been released into coastal areas increasing the environmental and human health risks, however, resuspension events of trace metals polluted sediment could represent even more severe risks.

Two Approaches to Measure Trace Metals Fluxes at the Sediment–Water Interface: Sediment Porewater Profile and Benthic Incubation

open access: yesASEAN Journal on Science and Technology for Development, 2020
The biogeochemical cycle of trace metals is very likely affected by the global change in the ocean, especially due to the increasing of sea surface temperature and acidity.

Trace metals and animal health: Interplay of the gut microbiota with iron, manganese, zinc, and copper

open access: yesAnimal Nutrition, 2021
Metals such as iron, manganese, copper, and zinc are recognized as essential trace elements. These trace metals play critical roles in development, growth, and metabolism, participating in various metabolic processes by acting as cofactors of enzymes or ...

Trends of labile trace metals in tropical urban water under highly contrasted weather conditions [PDF]

open access: yes, 2015
International audienceThe spatio-temporal trend of trace metals (Cd, Co, Cr, Cu, Ni, Pb, and Zn) in a tropical urban estuary under the influence of monsoon was determined using diffusive gradient in thin films (DGT) in situ samplers.

Preconcentration method for trace metals in natural waters using 4-morpholine dithiocarbamate [PDF]

open access: yesJournal of the Serbian Chemical Society, 2002
The optimum conditions were found for the preconcentration of trace metals in natural waters and model samples with standard metals concentrations by using 4-morpholinedithiocarbamate. The formed complexes were extracted with chloroform.
