Since their introduction in the late 1970s, sequential extraction procedures have
experienced a rapid increase in use. They are now applied for a large number of potentially …

A comprehensive review of the single and sequential extraction schemes for metal
fractionation in environmental samples such as soil and industrially contaminated soils …

Biochar, a green material that possesses high catalytic potential due to its persistent free
radicals (PFRs), has attracted increasing attention in the removal of refractory pollutants from …

Heavy metal (loid) s contamination is a constant issue at smelting sites. It is essential to
investigate the spatial distribution and migration characteristics of heavy metal (loid) s in the …

Some rivers in China have been seriously contaminated due to the discharge of lead (Pb)
smelting wastewater. In this study, biochar-supported nano-chlorapatite (BC-nClAP) was …

The chemical speciation of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in marine sediments
from two coastal regions of Singapore (Kranji in the NW, and Pulau Tekong in the NE) was …

Arsenic-alkali residue (AAR) and MSWI fly ash (MFA) are hazardous wastes, which still lack
effective treatment methods. In this study, a novel solidification/stabilization (S/S) method for …

Purpose The total concentration of trace elements in soils does not always represent the
fraction available for organisms and/or plants because they accumulate in several …

Heavy-metal pollution of soils has become a major environmental concern around the world
presently. Soil washing provides an effective measure of removing contaminants from soil …

Abstract Knowledge of the total concentration of heavy metals is not enough to fully assess
the environmental impact of urban soils. For this reason, the determination of metal …
