Soil plays an important role in controlling the biogeochemical cycling of nutrients and
contaminants in the environment. Reliable analytical techniques are critical to better …

The determination of the concentration of an environmental pollutant is not sufficient to
assess the related health risk because this pollutant may not be bioavailable. Therefore …

This critical review explores the quantification, analysis, and detection of radionuclides in the
environment using the diffusive gradients in thin films (DGT) technique. Radionuclides …

The speciation of trace metals in an aquatic system involves the determination of free ions,
complexes (labile and non-labile), colloids, and the total dissolved concentration. In this …

Yerba mate tea contains various biochemically active substances. However, it can contain
toxic metals. Thus, this work reports the total concentrations of Cd, Cu, Pb and Al in the …

A simple method was proposed by ultrasound-assisted emulsification microextraction
(UAEME) combined with GF AAS for Cr speciation in water samples using …

Barium (Ba) is a significant contaminant from shale gas extraction and is also used in
various other industries. However, there has been very limited attention paid to Ba …

Hydrolysis of acid oils is an important alternative for the production of non-ionic surfactants
and fatty acids that can be converted to fatty acid methyl esters (biodiesel) by esterification …

The uranium speciation in humic acid (HA) and fulvic acid (FA) model solutions was
investigated by diffusive gradients in thin films (DGT). A reference solution was used to …

Many contaminants have been released into the environment in recent times, requiring the
need to investigate these compounds presence, impact, and destination in different …
